Changelog

All notable changes to Ergo will be documented in this file.

[2.7.0-rc1] - 2021-05-30

We’re pleased to be publishing Ergo 2.7.0-rc1, our first release candidate under our new name of Ergo. This release contains bug fixes and minor enhancements.

This release includes changes to the config file format, all of which are fully backwards-compatible and do not require updating the file before upgrading. This release includes no changes to the database format.

Because the name of the executable has changed from oragono to ergo (ergo.exe on Windows), you may need to update your system configuration (e.g., scripts or systemd unit files that reference the executable).

Many thanks to @ajaspers and @jesopo for contributing patches, to @ajaspers, @ChrisTX, @emersion, @jwheare, @kylef, @Mikaela, @mogad0n, and @ProgVal for reporting issues and helping test, and to our translators for contributing translations.

Changed

The project was renamed from “Oragono” to “Ergo” (#897, thanks to everyone who contributed feedback or voted in the poll)

Config changes

Entries in server.listeners now take a new key, min-tls-version, that can be used to set the minimum required TLS version; the recommended default value is 1.2 (#1611, thanks @ChrisTX!)
Added max-conns (maximum connection count) and max-conn-lifetime (maximum lifetime of a connection before it is cycled) to datastore.mysql (#1622)
Added massmessage operator capability to allow sending NOTICEs to all connected users (#1153, #1629, thanks @jesopo!)

Security

If require-sasl.enabled is set to true, tor-listeners.require-sasl will be automatically set to true as well (#1636)
It is now possible to set the minimum required TLS version, using the min-tls-version key in listener configuration
Configurations that require SASL but allow user registration now produce a warning (#1637)

Added:

Operators with the correct permissions can now send “mass messages”, e.g. /NOTICE $$* will send a NOTICE to all users (#1153, #1629, thanks @jesopo!)
Operators can now extend the maximum (non-tags) length of the IRC line using the server.max-line-len configuration key. This is not recommended for use outside of “closed-circuit” deployments where IRC operators have full control of all client software. (#1651)

Fixed

RELAYMSG now sends a full NUH (“nick-user-host”), instead of only the relay nickname, as the message source (#1647, thanks @ProgVal, @jwheare, and @Mikaela!)
Fixed a case where channels would remain visible in /LIST after unregistration (#1619, thanks @ajaspers!)
Fixed incorrect tags on JOIN lines in +u (“auditorium”) channels (#1642)
Fixed an issue where LUSERS counts could get out of sync (#1617)
It was impossible to add a restricted set of snomasks to an operator’s permissions; this has been fixed (#1618)
Fixed incorrect language in NS INFO responses (#1627, thanks @ajaspers!)
Fixed a case where the REGISTER command would emit an invalid error message (#1633, thanks @ajaspers!)
Fixed snomasks displaying in a nondeterministic order (#1669, thanks @Mikaela!)

Removed

Removed the draft/resume-0.5 capability, and the associated RESUME and BRB commands (#1624)

Internal

Optimized MySQL storage of direct messages (#1615)

[2.6.1] - 2021-04-26

Oragono 2.6.1 is a bugfix release, fixing a security issue that is critical for some private server configurations. We regret the oversight.

The issue affects two classes of server configuration:

Private servers that use server.password (i.e., the PASS command) for protection. If accounts.registration.allow-before-connect is enabled, the REGISTER command can be used to bypass authentication. Affected operators should set this field to false, or upgrade to 2.6.1, which disallows the insecure configuration. (If the field does not appear in the configuration file, the configuration is secure since the value defaults to false when unset.)
Private servers that use accounts.require-sasl for protection. If these servers do not additionally set accounts.registration.enabled to false, the REGISTER command can potentially be used to bypass authentication. Affected operators should set accounts.registration.enabled to false; this recommendation appeared in the operator manual but was not emphasized sufficiently. (Configurations that require SASL but allow open registration are potentially valid, e.g., in the case of public servers that require everyone to use a registered account; accordingly, Oragono 2.6.1 continues to permit such configurations.)

This release includes no changes to the config file format or the database.

Many thanks to @ajaspers for reporting the issue.

Security

Fixed and documented potential authentication bypasses via the REGISTER command (#1634, thanks @ajaspers!)

[2.6.0] - 2021-04-18

We’re pleased to announce Oragono 2.6.0, a new stable release.

This release has some user-facing enhancements, but is primarily focused on fixing bugs and advancing the state of IRCv3 standardization (by publishing a release that implements the latest drafts). Some highlights:

A new CHATHISTORY API for listing direct message conversations (#1592)
The latest proposal for IRC-over-websockets, which should be backwards-compatible with existing clients (#1558)
The latest specification for the bot usermode (+B in our implementation) (#1562)

This release includes changes to the config file format, all of which are fully backwards-compatible and do not require updating the file before upgrading.

This release includes no changes to the embedded database format. If you are using MySQL for history storage, it adds a new table; this change is backwards and forwards-compatible and does not require any manual intervention.

If you are using nginx as a reverse proxy for IRC-over-websockets, previous documentation did not recommend increasing proxy_read_timeout; the default value of 60s is too low and can lead to user disconnections. The current recommended value is proxy_read_timeout 600s;; see the manual for an example configuration.

Many thanks to @ajaspers and @Mikaela for contributing patches, to @aster1sk, @emersion, @eskimo, @hhirtz, @jlu5, @jwheare, @KoraggKnightWolf, @kylef, @Mikaela, @mogad0n, @ProgVal, and @szlend for reporting issues and helping test, and to our translators for contributing translations.

Config changes

Listeners now support multiple TLS certificates for use with SNI; see the manual for details (#875, thanks @Mikaela!)
Added server.compatibility.allow-truncation, controlling whether the server accepts messages that are too long to be relayed intact; this value defaults to true when unset (#1577, #1586, thanks @kylef!)
Added new snomasks operator capability; operators must have either the ban or snomasks capability to subscribe to additional snomasks (#1176)

Security

Fixed several edge cases where Oragono might relay invalid UTF8 despite the UTF8ONLY guarantee, or to a text-mode websocket client (#1575, #1596, thanks @ProgVal!)
All operator privilege checks now use the capabilities system, making it easier to define operators with restricted powers (#1176)
Adding and removing bans with UBAN now produces snomasks and audit loglines (#1518, thanks @mogad0n!)

Fixed

Fixed an edge case in line buffering that could result in client disconnections (#1572, thanks @ProgVal!)
Upgraded buntdb, our embedded database library, fixing an edge case that could cause data corruption (#1603, thanks @Mikaela, @tidwall!)
Improved compatibility with the published draft/register specification (#1568, thanks @ProgVal!)
433 ERR_NICKNAMEINUSE is no longer sent when a fully connected (“registered”) client fails to claim a reserved nickname, fixing a bad interaction with some client software (#1594, thanks @ProgVal!)
Fixed znc.in/playback commands causing client disconnections when history is disabled (#1552, thanks @szlend!)
Fixed syntactically invalid 696 ERR_INVALIDMODEPARAM response for invalid channel keys (#1563, thanks @ProgVal!)
User-set nickserv settings now display as “enabled” instead of “mandatory” (#1544, thanks @Mikaela!)
Improved error messages for some invalid configuration cases (#1559, thanks @aster1sk!)
Improved CS TRANSFER error messages (#1534, thanks burning!)
Handle panics caused when rehashing with SIGHUP (#1570)

Changed

Registered channels will always appear in /LIST output, even with no members (#1507)
In the new recommended default configuration, Oragono will preemptively reject messages that are too long to be relayed to clients without truncation. This is controlled by the config variable server.compatibility.allow-truncation; this field defaults to true when unset, preserving the legacy behavior for older config files (#1577, #1586, thanks @kylef!)
Auto-away behavior now respects individual clients; the user is not considered away unless all clients are away or disconnected (#1531, thanks @kylef!)
Direct messages rejected due to the +R registered-only usermode now produce an error message (#1064, thanks @KoraggKnightWolf, @ajaspers!)
RELAYMSG identifiers now respect bans and mutes (#1502)
If end user message deletion is enabled, channel operators can now delete channel messages (#1565, thanks @Mikaela!)
Halfops can change the channel topic (#1523)
Snomask add/remove syntax now matches other ircds more closely (#1074)
CS OP will regrant your channel AMODE, in case you removed it (#1516, #1307, thanks @jlu5!)
User passwords may no longer begin with : (#1571)
Improved documentation of CS AMODE and NS UNREGISTER (#1524, #1545, thanks @Mikaela!)
Disabling history disables history-related CAPs (#1549)

Added

Implemented the new CHATHISTORY TARGETS API for listing direct message conversations (#1592, thanks @emersion, @hhirtz, @jwheare, @kylef!)
Implemented the new IRC-over-websockets draft, adding support for binary websockets and subprotocol negotiation (#1558, thanks @jwheare!)
Implemented the new bot mode spec (#1562)
Implemented the new forward mode spec (#1612, thanks @ProgVal!)
WARN NICK ACCOUNT_REQUIRED is sent on failed attempts to claim a reserved nickname (#1594)
NS CLIENTS LIST displays enabled client capabilities (#1576)
CS INFO with no arguments lists your registered channels (#765)
NS PASSWORD is now accepted as an alias for NS PASSWD (#1547)

Internal

Upgraded to Go 1.16 (#1510)

[2.5.1] - 2021-02-02

Oragono 2.5.1 is a bugfix release that fixes a significant security issue. We apologize for the oversight.

This release includes no changes to the config file format or the database.

Many thanks to @xnaas for reporting the issue.

Security

Fix an incorrect permissions check in NickServ (#1520, thanks @xnaas!)

[2.5.0] - 2021-01-31

We’re pleased to announce Oragono 2.5.0, a new stable release.

This release includes enhancements based on the needs of real-world operators, as well as bug fixes. Highlights include:

UBAN, a new “unified ban” system for server operators, with a corresponding CHANSERV HOWTOBAN command for channel operators (#1447)
A new forwarding/overflow channel mode +f (#1260)
Support for PROXY protocol v2 (#1389)

This release includes changes to the config file format, including two breaking changes. One is fairly significant: enabling a websocket listener now requires the use of server.enforce-utf8, as has been the recommended default since 2.2.0 (so continuing to accept legacy non-UTF-8 content will require disabling websockets). The other is that the “unban” operator capability has been removed (it is now included in the “ban” capability). Other config changes are backwards compatible and do not require updating the file before upgrading.

This release includes a database change. If you have datastore.autoupgrade set to true in your configuration, it will be automatically applied when you restart Oragono. Otherwise, you can update the database manually by running oragono upgradedb (see the manual for complete instructions).

Many thanks to @jlu5, @kylef and @Mikaela for contributing patches, to @bogdomania, @eskimo, @happyhater, @jlu5, @kylef, @LukeHoersten, @Mikaela, @mogad0n, @robinlemon, and @vertisan for reporting issues and helping test, and to our translators for contributing translations.

Config changes

Enabling websockets now requires server.enforce-utf8 = true (#1483)
proxy is now a top-level field of the listener config block; in particular, the PROXY protocol (v1 or v2) can now be required ahead of a plaintext connection. The field is still accepted in its legacy position (inside the tls block). (#1389, thanks @robinlemon!)
Added accounts.multiclient.always-on-expiration, allowing always-on clients to be timed out for inactivity (#810, thanks @bogdomania!)
local_ prefixes have been stripped from operator capability names, so that, e.g., local_ban is now just ban. The old names are still accepted. (#1442)
The local_unban operator capability has been removed (unbanning is now contained in the ban permission). (#1442)
The recommended value of accounts.bcrypt-cost is now 4, the minimum acceptable value (#1497)
server.ip-limits.custom-limits now accepts networks that contain multiple CIDRs; the old syntax is still accepted (#1421, thanks @Mikaela!
A new field, history.restrictions.query-cutoff, generalizes the old history.restrictions.enforce-registration-date (the old field is still accepted) (#1490, thanks @Mikaela!)
Added server.override-services-hostname, allowing the hostname of NickServ, ChanServ, etc. to be overridden (#1407, thanks @Mikaela!)
Added a boolean hide-sts key to the listener block; this can be used to hide the STS CAP when the listener is secured at layer 3 or 4 (e.g., by a VPN or an E2E mixnet). It will still be necessary to add the relevant IPs to secure-nets. (#1428, thanks @Mikaela!)

Security

Improved validation of names and encodings for client-only tags (#1385)
Improved auditability of sensitive operator actions (#1443, thanks @mogad0n!)
DEFCON 4 and lower now require Tor users to authenticate with SASL (#1450)

Fixed

Fixed NS UNSUSPEND requiring the casefolded / lowercase version of the account name (#1382, thanks @mogad0n!)
Fixed client-only tags in direct (user-to-user) PRIVMSG not being replayed (#1411)
Fixed many bugs in import of Anope and Atheme databases (#1403, #1423, #1424, #1431, #1435, #1439, #1444, thanks @jlu5, @kylef, and @Mikaela!)
Fixed case-handling bugs in RENAME (i.e., channel rename) (#1456, thanks @mogad0n!)
Fixed incorrect processing of color code escapes in MOTD files (#1467, thanks @mogad0n!)
STS is no longer advertised to Tor clients (#1428, thanks @Mikaela!)
Fixed HELP/HELPOP numerics not including the nick as an argument (#1472, thanks @kylef!)
Made connection registration snomasks less confusing (#1396, thanks @eskimo!)
Fixed duplicated nicks in KLINE response (#1379, thanks @mogad0n!)
The RELAYMSG tag name is now draft/relaymsg, conforming to the amended draft specification (#1468, thanks @jlu5!)
Fixed SAJOIN not sending a MODE line to the originating client (#1383, thanks @mogad0n!)
Improved consistency of message sources sent by CS AMODE (#1383, thanks @mogad0n!)
Fixed duplicated JOIN line sent to some clients using the draft/resume-0.5 extension (#1397, thanks @kylef!)
Added a warning that MySQL cannot be enabled by rehash (#1452, thanks @Mikaela!)

Changed

Channel-user modes (e.g., +o, +v) of always-on clients are now persisted in the database (#1345)
/CHANSERV PURGE now takes ADD, DEL, and LIST subcommands; the separate UNPURGE command has been removed; PURGE ADD now requires a confirmation code (#1294, thanks @mogad0n!)
The characters <, >, ', ", and ; are no longer allowed in nicknames (previously registered account names containing these characters are still accepted) (#1436, thanks @happyhater!)
Authenticated clients from Tor now receive their (account-unique) always-on cloaked hostname; this allows channel operators to ban unauthenticated Tor users by banning *!*@tor-network.onion (#1479, thanks @mogad0n!)
Included the network name in the human-readable final parameter of 001 RPL_WELCOME (#1410)
RELAYMSG can now take client-only tags (#1470)
WebSocket listeners will attempt to negotiate the text.ircv3.net subprotocol; negotiating this is optional for clients (#1483)

Added

Added UBAN, a new command giving server operators a unified interface to D-LINEs (IP bans), K-LINEs (NUH mask bans, which are now deprecated), and account suspensions (NS SUSPEND) (#1447)
Added CHANSERV HOWTOBAN, a ChanServ subcommand that helps channel operators choose an appropriate ban (#1447)
Added a new channel mode +f; users who cannot join the channel due to +i or +l will be forwarded to the channel specified by +f. (#1260)
Added support for the PROXY protocol v2 (#1389, thanks @robinlemon!)
Added support for /JOIN 0 (part all channels), requiring a confirmation code (#1417, thanks @Mikaela!)
Added support for grouped nicknames as SASL usernames (#1476, thanks @eskimo!)
Added history support for INVITE (#1409, thanks @Mikaela!)
Added a new channel setting accessible via /CS SET: history-cutoff, allowing the channel owner more fine-grained control over who can see history (#1490, thanks @Mikaela!)
Added the UTF8ONLY ISUPPORT token, allowing the server to advertise to clients that only UTF-8 content is accepted (#1483)
Added /NICKSERV RENAME, an operator-only command that can change the case of an account name (#1380, thanks @LukeHoersten!)

Internal

Added caching for serialized messages (#1387)
Improved memory efficiency of line reading (#1231)

[2.4.0] - 2020-11-08

We’re pleased to announce Oragono 2.4.0, a new stable release.

This release includes a number of exciting enhancements and fixes. Here are some highlights:

Support for migrating an Anope or Atheme database to Oragono (#1042)
A pluggable system for validating external IPs, e.g., via DNSBLs (#68, thanks @moortens!)
draft/relaymsg, a new draft extension simplifying bridging with other chat systems (thanks @jlu5!)
New moderation tools: +u (“auditorium”, #1300), +U (“op-moderated”, #1178), +M (“moderated-registered”, #1182, thanks @ajaspers!), and +b m: (an extban for muting users, #307)

This release includes changes to the config file format, including one breaking change: roleplay.enabled now defaults to false (the new recommended default) instead of true when unset. Other config changes are backwards compatible and do not require updating the file before upgrading.

Many thanks to @ajaspers, @jesopo, @moortens, and @RunBarryRun for contributing patches, to @csmith for contributing code reviews, to @ajaspers, @Amiga60077, @bogdomania, @csmith, @edk0, @eskimo, @jlu5, @jwheare, @KoraggKnightWolf, @Mitaka8, @mogad0n, @RyanSquared, and @vertisan for reporting issues and helping test, and to our translators for contributing translations.

Config changes

Added server.ip-cloaking.enabled-for-always-on, which generates a unique hostname for each always-on client. The recommended default value of this field is true (#1312)
Added server.coerce-ident; if this is set to a string value, all user/ident fields supplied by clients are ignored and replaced with this value. The recommended default value of this field is ~u. This simplifies bans. (#1340)
Simplified the config file format for email verification into a new accounts.nick-reservation.email-verification section. The old format (callbacks) is still accepted (#1075)
The recommended value of roleplay.enabled is now false; this field now defaults to false when unset (#1240, #1271)
Added server.relaymsg section for configuring the new draft/relaymsg capability; added the new relaymsg operator capability for exercising it (#1119)
Added allow-environment-overrides config variable, allowing config options to be overridden by environment variables. See the manual for more details. (#1049, thanks @csmith!)
Added server.ip-check-script for configuring IP check plugins (#68, #1267, thanks @moortens!)
Added max-concurrency restriction to accounts.auth-script section. The recommended default value is 64 (0 or unset disable the restriction) (#1267)
Added accounts.registration.allow-before-connect; this allows the use of the new REGISTER command before connecting to the server (#1075)
Added hidden option in operator blocks: if set to true, operator status is hidden from commands like WHOIS that would otherwise display it (#1194)
Added accounts.nick-reservation.forbid-anonymous-nick-changes, which forbids anonymous users from changing their nicknames after initially connecting (#1337, thanks @Amiga60077!)
Added channels.invite-expiration, allowing invites to +i channels to expire after a given amount of time (#1171)

Security

Added /NICKSERV CLIENTS LOGOUT command for disconnecting clients connected to a user account (#1072, #1272, thanks @ajaspers!)
Disallowed the use of service nicknames during roleplaying (#1240, thanks @Mitaka8!)
Improved security properties of INVITE for invite-only channels, including an UNINVITE command (#1171)

Removed

Removed the request queue system for HostServ, i.e., the REQUEST, APPROVE, and REJECT subcommands of HOSTSERV (#1346)

Fixed

PONG is now sent with the server name as the first parameter, matching the behavior of other ircds (#1249, thanks @jesopo!)
It was not possible to set or unset the +T no-CTCP user mode; this has been fixed (#1299, thanks @mogad0n!)
Fixed edge cases with /NICKSERV SAREGISTER of confusable nicknames (#1322, thanks @mogad0n!)
Fixed websocket listeners with proxy-before-TLS enabled closing on invalid PROXY lines (#1269, thanks @RyanSquared!)
Fixed error responses and history for SANICK (#1277, #1278, thanks @eskimo!)
Ensured that stored realnames of always-on clients are deleted during account unregistration (#1330)
Whitespace is now stripped from KLINEs (#1327, thanks @mogad0n!)
Fixed incorrect LUSERS counts caused by KLINE (#1303, thanks @mogad0n!)
CHATHISTORY queries for invalid channels now get an empty batch instead of a FAIL (#1322)
fakelag.messages-per-window = 0 no longer causes a panic (#861, thanks @vertisan!)

Added

Added oragono importdb command for importing a converted Anope or Atheme database; see the manual for details (#1042)
Added support for the new draft/relaymsg extension, which simplifies bridging IRC with other protocols relaymsg (#1119, thanks @jlu5!)
Added ip-check-script, a scripting API for restricting access by client IP. We provide oragono-dnsbl, an external script that can query DNSBLs for this purpose (#68, #1267, thanks @moortens!)
Added channel mode +u. This is an “auditorium” mode that prevents unprivileged users from seeing each other’s JOIN and PART lines. It’s useful for large public-announcement channels, possibly in conjunction with +m (#1300)
Added channel mode +U. This is an “op-moderated” mode; messages from unprivileged users are sent only to channel operators, who can then choose to grant them +v. (#1178)
Added a mute extban +b m:: users matching the ban expression (e.g., +b m:*!*@j6dwi4vacx47y.irc) will be able to join the channel, but will be unable to speak. (#307)
Added support for the new draft/register extension, which exposes a cleaner account registration API to clients (#1075, thanks @edk0!)
Added a 379 RPL_WHOISMODES line to the WHOIS response, making it easier for operators to see other users’ modes (#769, thanks @Amiga60077 and @KoraggKnightWolf!)
Added /CHANSERV DEOP command for removing channel operator privileges (#361, thanks @RunBarryRun!)
Added r flag to /WHO responses for registered nicknames (#1366, thanks @Amiga60077!)

Changed

Always-on clients now receive a user/ident of ~u by default, instead of ~user; this can be changed by setting the coerce-ident field (#1340)
/NICKSERV SUSPEND has been modified to take subcommands (ADD, DEL, and LIST); the ADD subcommand now accepts time duration and reason arguments. See /msg NickServ HELP SUSPEND for details. (#1274, thanks @mogad0n!)
Only the channel founder can kick the channel founder, regardless of either party’s modes (#1262)
/NICKSERV SESSIONS is now /NICKSERV CLIENTS LIST, but the old command is still accepted (#1272, thanks @ajaspers!)
Improved SETNAME behavior for legacy clients (#1358, thanks @KoraggKnightWolf!)
Halfops can set the channel topic (#1306)
Full client certificates are now passed to auth scripts. This allows for more flexible checks on certificates, including verification against an internal CA (#414)

Internal

Added a logline for debugging client disconnections (#1293)
Renamed conventional.yaml to traditional.yaml (#1350)
Integration tests are now run during CI (#1279)

[2.3.0] - 2020-09-06

We’re pleased to announce Oragono 2.3.0, a new stable release.

This release contains primarily bug fixes, but includes one notable feature enhancement: a change contributed by @hhirtz that updates the draft/rename specification to correspond to the new (soon-to-be) published draft.

Many thanks to @hhirtz for contributing patches, to @bogdomania, @digitalcircuit, @ivan-avalos, @jesopo, @kylef, @Mitaka8, @mogad0n, and @ProgVal for reporting issues and helping test, and to our translators for contributing translations.

This release includes no changes to the config file format or database changes.

Config changes

The recommended value of lookup-hostnames for configurations that cloak IPs (as has been the default since 2.1.0) is now false (#1228)

Security

Mitigated a potential DoS attack on websocket listeners (#1226)

Removed

Removed /HOSTSERV OFFERLIST and related commands; this functionality is superseded by IP cloaking (#1190)

Fixed

Fixed an edge case in handling no-op nick changes (#1242)
Fixed edge cases with users transitioning in and out of always-on status (#1218, #1219, thanks @bogdomania!)
Fixed a race condition related to the registration timeout (#1225, thanks @hhirtz!)
Fixed incorrectly formatted account tags on some messages (#1254, thanks @digitalcircuit!)
Improved checks for invalid config files (#1244, thanks @ivan-avalos!)
Fixed messages to services and *playback not receiving echo-message when applicable (#1204, thanks @kylef!)
Fixed a help string (#1237, thanks @Mitaka8!)

Changed

Updated draft/rename implementation to the latest draft (#1223, thanks @hhirtz!)

Internal

Official release builds now use Go 1.15 (#1195)
/INFO now includes the Go version (#1234)

[2.2.0] - 2020-07-26

We’re pleased to announce Oragono 2.2.0, a new stable release.

This release contains several notable enhancements, as well as bug fixes:

Support for tracking seen/missed messages across multiple devices (#843)
WHOX support contributed by @jesopo (#938)
Authentication of users via external scripts (#1107)

Many thanks to @clukawski and @jesopo for contributing patches, to @ajaspers, @bogdomania, @csmith, @daurnimator, @emersonveenstra, @eskil, @eskimo, Geo-, @happyhater, @jesopo, @jwheare, @k4bek4be, @KoraggKnightWolf, @kylef, @LukeHoersten, @mogad0n, r3m, @RyanSquared, savoyard, and @wrmsr for reporting issues and helping test, and to our translators for contributing translations.

This release includes changes to the config file format, including one breaking change: timeout is no longer an acceptable value of accounts.nick-reservation.method. (If you were using it, we suggest strict as a replacement.) All other changes to the config file format are backwards compatible and do not require updating before restart.

Removed

Timeout-based nickname enforcement has been removed. We recommend strict as the default enforcement method. Users who configured timeout for their account will be upgraded to strict. With accounts.login-via-pass-command enabled, clients lacking support for SASL can authenticate via the PASS (server password command) by sending account_name:account_password as the server password. (#1027)
Native support for LDAP has been removed. LDAP is now supported via the external oragono-ldap plugin; see its repository page for details. (#1142, #1107)

Config changes

Added server.enforce-utf8, controlling whether the server enforces that messages be valid UTF-8; a value of true for this is now the recommended default (#1151)
Added history.tagmsg-storage for configuring which TAGMSG are stored in history; if this is not configured, TAGMSG will not be stored (#1172)
All TLS certificate fingerprints in the config file are now named certfp instead of fingerprint (the old name of fingerprint is still accepted) (#1050, thanks @RyanSquared!)
Added accounts.auth-script section for configuring external authentication scripts (#1107, thanks @daurnimator!)
Removed accounts.ldap section for configuring LDAP; LDAP is now available via the auth-script plugin interface (#1142)
Added defcon operator capability, allowing use of the new /DEFCON command (#328)
Default awaylen, kicklen, and topiclen limits now reflect the 512-character line limit (#1112, thanks @k4bek4be!)
Added extjwt section for configuring the EXTJWT extension (#948, #1136)
login-via-pass-command: true is now a recommended default (#1186)

Added

Added support for WHOX, contributed by @jesopo (#938, thanks!)
Added support for tracking missed messages across multiple devices; see the “history” section of the manual for details (#843, thanks @jwheare and @wrmsr!)
Added /NICKSERV SUSPEND and /NICKSERV UNSUSPEND commands, allowing operators to suspend access to an abusive user account (#1135)
Added support for external authentication systems, via subprocess (“auth-script”) invocation (#1107, thanks @daurnimator!)
Added the /DEFCON command, allowing operators to respond to spam or DoS attacks by disabling features at runtime without a rehash.

[2.1.0] - 2020-06-01

We’re pleased to announce Oragono 2.1.0, a new stable release.

Since the release of 2.0.0 in March, a number of new communities and organizations have adopted Oragono as a communications tool. This new release incorporates many improvements and fixes derived from the experiences of real-world operators and end users. Highlights include:

Native support for websockets contributed by @hhirtz, eliminating the need for a separate websockets-to-IRC proxy server
Tighter control over the relationship between account names and nicknames, eliminating the need for extbans
Support for sending account verification emails directly from Oragono, including DKIM signatures

Many thanks to @ajaspers and @hhirtz for contributing patches, to @ajaspers, @eklitzke, and @hhirtz for contributing code reviews, to @ajaspers, @bogdomania, @clukawski, Csibesz, @csmith, @eklitzke, @nxths, @hhirtz, @jesopo, @jlnt, @justjanne, @jwheare, @k4bek4be, @KoraggKnightWolf, @kula, @kylef, @Mitaka8, @petteri, @PizzaLover2007, @prawnsalad, @RyanSquared, savoyard, and @xPaw for reporting issues, and to @bogdomania, @boppy, Nuve, stickytoffeepuddingwithcaramel, and @vegax87 for contributing translations.

This release includes changes to the config file format, including one breaking change: support for server.ip-cloaking.secret-environment-variable has been removed. (See below for instructions on how to upgrade if you were using this feature.) All other changes to the config file format are backwards compatible and do not require updating before restart.

This release includes a change to the MySQL schema. This change will be applied automatically when you restart Oragono. It is fully backwards compatible (i.e., if it is necessary for you to downgrade Oragono back to 2.0.0, it will not be necessary to downgrade the schema).

Config Changes

Added websocket attribute of individual listeners, and a new server.websockets section, for configuring websocket listeners. (#967, thanks @hhirtz!)
The recommended default is now to enable IP cloaking. In order to facilitate this, the cloaking secret is now stored in the database, instead of the config file. If you currently have a secret stored in the config file (as server.ip-cloaking.secret), it will be automatically imported into the database. If you were using secret-environment-variable to distribute your cloaking secret, you can import it manually after restart using the new /HOSTSERV SETCLOAKSECRET command. (#952)
Added accounts.nick-reservation.force-nick-equals-account, which ensures that logged-in clients are using their account name as their nickname. This eliminates the need for extbans and is a new recommended default. (#864)
Added guest-nickname-format and force-guest-format, which optionally add a prefix like Guest- to the nicknames of unauthenticated users (#749)
The recommended default is now to enable history storage and playback, with messages expiring after 7 days. (As with all changes in recommended config values, applying this to an existing config file requires explicitly changing the values.) (#1030)
Added history.retention section for controlling new features related to history storage and deletion (#858)
The recommended default for accounts.multiclient.always-on is now opt-in (#919)
Added accounts.default-user-modes; the recommended default is now to set +i on all users automatically (#942, thanks @ajaspers!)
Added channels.list-delay, allowing restrictions on channel listings as a defence against spambots (#964)
Added accounts.multiclient.auto-away, allowing always-on clients to be automatically marked as away when all their sessions disconnect
Added accounts.throttling as a global throttle on the creation of new accounts (#913)
New format for accounts.callbacks.mailto, allowing direct email sending and DKIM signing (#921)
Added accounts.login-via-pass-command, providing a new mechanism for legacy clients to authenticate to accounts by sending PASS account:password pre-registration (#1020)
Added datastore.mysql.socket-path, allowing MySQL connections over UNIX domain sockets (#1016, thanks savoyard and @ajaspers!)
Added roleplay section for controlling the server’s roleplay features (#865)
The recommended default for accounts.nick-reservation.allow-custom-enforcement is now false (#918)
The recommended default is now to allow PROXY and WEBIRC lines from localhost (#989, #1011)
Added channels.registration.operator-only, optionally restricting channel registrations to operators (#685)
Added server.output-path for controlling where the server writes output files (#1004)
Operator capability names prefixed with oper: have been normalized to remove the prefix (the old names are still respected in the config file) (#868)
The log category names localconnect and localconnect-ip have been changed to connect and connect-ip respectively (the old names are still respected in the config file) (#940)

Security

Fixed incorrect enforcement of ban/invite/exception masks under some circumstances (#983)
STATUSMSG were being stored in history without the relevant minimum-prefix information, so they could be replayed to unprivileged users. This was fixed by not storing them at all. (#959, thanks @prawnsalad!)
Fixed invisible users not being hidden from WHO * queries (#991, thanks @ajaspers!)
Restricted nicknames of some additional common services: OperServ, BotServ, MemoServ, and Global (#1080, thanks @KoraggKnightWolf!)

Fixed

Fixed incorrect rejection of draft/multiline messages containing blank lines (#1005, thanks @jwheare!)
Fixed roleplay commands, which were completely broken from v1.1.0 through v2.0.0 (#865, thanks @petteri and @Mitaka8!)
Fixed /SAMODE applying user mode changes to the operator instead of the target user (#866, thanks @csmith!)
Fixed some channels not being unregistered during account unregistration (#889)
Fixed /NICKSERV SET and related commands being unavailable when account registration is disabled (#922, thanks @PizzaLover2007!)
Fixed TAGMSG not being replayed correctly in history (#1044)
Fixed incorrect 401 ERR_NOSUCHNICK responses on TAGMSG sent to a service (#1051, thanks @ajaspers!)
Fixed 301 RPL_AWAY not being sent in WHOIS responses when applicable (#850)
/OPER with no password no longer disconnects the client (#951)
Fixed failure to send extended-join responses after account unregistration (#933, thanks @jesopo!)
Improved validation of channel keys (#1021, thanks @kylef!)
Fixed labeling of 421 ERR_UNKNOWNCOMMAND responses (#994, thanks @k4bek4be!)
Fixed incorrect parsing of ident protocol responses (#1002, thanks @justjanne!)
Fixed registration completing after NICK and an ident response, without waiting for USER (#1057, thanks @KoraggKnightWolf!)
Fixed messages rejected by the +R mode being stored in history (#1061, thanks @KoraggKnightWolf!)
Fixed redundant /INVITE commands not sending 443 ERR_USERONCHANNEL (#842, thanks @hhirtz!)

Fixed error message when attempting to attach a plaintext session to an always-on client (#955, thanks @bogdomania and @xPaw!)
Increased the TLS handshake timeout, increasing reliability under high CPU contention (#894)
Fixed CHANMODES ISUPPORT token (#408, #874, thanks @hhirtz!)
Fixed 002 RPL_MYINFO parameters (#1058, thanks @KoraggKnightWolf!)
Fixed incorrect parameter limit for MONITOR in the TARGMAX isupport token (#1090, thanks @KoraggKnightWolf!)
Fixed edge cases in handling of the +k channel mode parameter (#874, thanks @hhirtz!)
account-notify lines are now part of the labeled-response batch when applicable (#1018)
Fixed incorrect help description of channel mode +R (#930, thanks @PizzaLover2007!)
Fixed 255 RPL_LUSERME response to indicate that the number of federated peer servers is 0 (#846, thanks @RyanSquared!)

Changed

Account names are now permanent identifiers; they cannot be re-registered after unregistration, and applicable nickname protections remain in force. (#793)
User modes of always-on clients now persist across server restarts (#819)
Registered channels with no members remain present on the server, including their in-memory history messages when applicable (#704, thanks @bogdomania!)
Updated the setname IRCv3 capability to its ratified version (#1001)

Cleaned up compatibility with an obsolete WEBIRC escaping convention (#869)
The cloak secret is now stored in the database, so it can no longer be rotated by changing server.ip-cloaking.secret. To rotate the secret, use the new /HOSTSERV SETCLOAKSECRET command. (#952)

Added

Added native support for websockets (#967, thanks @hhirtz!)
Added support for sending verification emails directly (i.e., without a MTA/smarthost), including DKIM signing (#920, #921)
Added /NICKSERV LIST and /CHANSERV LIST, allowing operators to list registered nicknames and channels (#974, thanks @ajaspers!)
Added auto-away feature for marking always-on clients away when all their sessions are disconnected; see accounts.multiclient.auto-away and /NICKSERV HELP SET for more information (#824)
Added /HISTSERV PLAY, which plays back history messages as NOTICEs from the HistServ service (#383, thanks @nxths!)
Added /HISTSERV DELETE for deleting history messages (see the config option history.retention.allow-individual-delete) (#858)

Added support for restricting /LIST responses sent to anonymous clients (#964)
Added support for the Plan 9 operating system and its derivatives, including testing on 9front (#1025, thanks @clukawski!)

Removed

Removed support for colored log output (#940, #939)
Removed support for distributing the cloaking secret via environment variables (#952)

Internal

make build now includes an abbreviated git hash in the 002 RPL_YOURHOST and 004 RPL_MYINFO version strings, when applicable (#1031)
Official releases no longer contain the git hash, only the revision tag (#1031)

[2.0.0] - 2020-03-08

We’re pleased to announce Oragono 2.0.0, a major update with a wide range of enhancements and fixes. Highlights include:

Support for storing chat history in a MySQL backend
Full “bouncer” functionality, including “always-on” clients that remain present on the server even when disconnected
LDAP support contributed by @mattouille
Support for the ratified labeled-response IRCv3 capability
Enhanced support for Kubernetes
Many new service commands, improving management of client certificates, vhosts, and channel ownership

Many thanks to @csmith, @mattouille, and @xPaw for contributing patches, to @csmith and @wrmsr for contributing code reviews, to @bogdomania, @brenns10, @daurnimator, @ekianjo, horseface, @ivucica, @jesopo, @jwheare, KoDi, lover, @notbandali, @poVoq, @TETYYS, and @zaher for reporting issues, and to @bogdomania and Nuve for contributing translations.

This release includes changes to the config file format, including two breaking changes:

Backwards compatibility with the old server.listen format for configuring listeners has been removed; you must now use the server.listeners format that was introduced in 1.2.0.
The two sections server.connection-limits and server.connection-throttling have been consolidated into one new section, server.ip-limits.

Other changes to the config file format are backwards compatible and do not require updating before restart. To minimize potential downtime, we suggest the following workflow:

Without upgrading your oragono binary, edit your config file to add new server.listeners and server.ip-limits sections, based on the example config file
Rehash your server, confirming that the new config file is valid for for the previous version of the server
Upgrade your oragono binary to the new 2.0.x version and restart your server
Once your deployment is stable on 2.0.x, delete the old server.listen, server.connection-limits, and server.connection-throttling sections from your config, and rehash your server to confirm

[1.2.0] - 2019-11-17

We’re pleased to announce Oragono 1.2.0. This version contains bug fixes and minor improvements.

Many thanks to @bogdomania, @csmith, @edmund-huber, @jesopo, @jwheare, @poVoq, @prawnsalad, and stealthgin for reporting issues and contributing code reviews, and also to @bogdomania, Forbidden (cptbl00dra1n), Nuve, @streaps, and UnLokitoFeliz for contributing translations.

This release includes a change to the config file format: the old server.listen format for configuring listeners has been replaced by a new server.listeners format. See the bundled oragono.yaml configuration file for a commented example. For now, Oragono maintains backwards compatibility with the old format. To minimize potential downtime, we recommend the following workflow:

Without rewriting your config file, upgrade your oragono binary to the new 1.2.x version and restart your server
Rewrite your configuration file to use the new server.listeners format
Rehash your server, confirming that the rewritten config file is valid and correct

Config Changes

Replaced server.listen section with server.listeners; see oragono.yaml for a commented example (#565)
Added history.autoresize_window for automatically resizing history buffers (#349)

Added

Added STS-only listeners; you can configure port 6667 so that it “redirects” clients to TLS on port 6697. See the manual for details. (#448)
Added the CHANLIMIT ISUPPORT token (#625, thanks @poVoq!)
Added ban creator and creation time to banlist output (#644, thanks stealthgin!)

Changed

Upgraded to the new draft/labeled-response-0.2 capability (#555)
oragono mkcerts no longer overwrites existing certificate files (#622, thanks @poVoq!)
Allowed Tor and non-Tor connections to attach to the same nickname via bouncer functionality (#632)

Fixed

Fixed CAP LS 302 response being potentially truncated (#594, #661)
Fixed redundant output to some MODE commands (#649)
Improved display of replies to /msg NickServ verify in some clients (#567, thanks @edmund-huber!)
Improved display of NickServ timeout warnings in some clients (#572, thanks @bogdomania!)

Fixed an edge case where the BRB timestamp wasn’t reset correctly (#642)
Fixed behavior of SAMODE issued against a different user (#585)
Fixed a false-positive error logline (#601)
oragono.io/bnc is no longer advertised when disabled in the config (#595)
Made the connection limiter and throttler more resilient against the failure to whitelist a reverse proxy IP (#197, thanks @prawnsalad!)

Internal Notes

Official builds now use Go 1.13, which includes native TLS 1.3 support (#626)
Minor performance improvements (#640, #615)

[1.1.1] - 2019-07-21

Oragono 1.1.1 is a bugfix release for flaws in message handling, including one with security implications.

Many thanks to @streaps for reporting issues.

Upgrade notes

This release does not change the database or configuration file format.

Security

Previous releases of Oragono would incorrectly relay chat messages containing the \r byte. An attacker could use this to spoof protocol messages from the server (depending on the implementation of the victim’s client). This has been fixed. (#610)

Fixed

Fixed incorrect rejection of messages with multiple spaces (#602, thanks @streaps!)

[1.1.0] - 2019-06-27

We’re pleased to announce Oragono version 1.1.0. This version has a number of exciting improvements, including:

Simplified commands for registering new accounts with NickServ.
Support for IP cloaking.
Support for attaching multiple clients to the same nickname.
Support for the newly ratified message tags and message ID IRCv3 specifications; client developers are invited to use Oragono as a reference when implementing these specifications.
Support for running Oragono as a Tor hidden service.

Many thanks to @Ascrod, @amyspark, @bogdomania, @csmith, @jesopo, @jwheare, lover, and @transitracer for reporting issues and contributing patches, and also to @bogdomania, Elvedin Hušić, Nuve, and @streaps for contributing translations.

Upgrade notes

No changes to your configuration file should be required for this upgrade. However, updating the file is necessary to enable some new functionality, as described below.

Config changes

tor-listeners section added for configuring listeners for use with Tor.
compatibility section added for toggling compatibility behaviors for legacy clients.
ip-cloaking section added for configuring cloaking.
bouncer section added for configuring bouncer-like features (in particular, whether multiple clients can use the same nickname).
check-ident now has recommended value false.
nick-reservation.method now has recommended value “strict”`.
fakelag.enabled now has recommended value true.
limits.linelen.tags removed due to ratification of the message-tags spec, which fixes the maximum tags length at 8191 bytes.
limits.registration-messages added to restrict how many messages a user can send to the server during connection registration (while connecting to the server).
channels.operator-only-creation added to optionally restrict creation of new channels to ircops (#537).

Security

Users can no longer impersonate network services like ChanServ by using confusing nicks like “ChɑnServ” (#519, thanks @csmith!).
Closed several loopholes in confusable nick detection (#562, #564, #570, thanks lover!)
Secret channels (mode +s) now act more secret (#380, thanks @csmith!).
The +R (registered-only) mode now prevents unregistered users from joining the channel, not just from speaking (#463, thanks @bogdomania!).
Limited how many messages clients can send during connection registration to mitigate potential DoS attacks (#505).
Attempting to reauthenticate with SASL now fails with 907 ERR_SASLALREADY (#476).

Fixed

We now treat channel privileges such as halfop more consistently (#400).
Fixed a bug where clients could receive message tags they hadn’t enabled (#434).
When replaying history, messages now have more consistent IDs and timestamps
IDs and timestamps are now applied more consistently to messages (#388, #477, #483).
Client-to-client tags are now stored and replayed in message history (#437).
Fixed various error numerics that were being sent with incorrect parameters (#425, thanks @Ascrod!).
Fixed STATUSMSG not adding the correct prefix to the channel when relaying the message (#467).
Fixed /RENAME command not correctly renaming the channel for some users (#300, thanks @jesopo!).
History playback is now batched when applicable (#456, thanks @transitracer!).
Notices from NickServ/ChanServ/etc should display better in some clients (#496, thanks @jwheare!).
Fixed nickname timer warnings not displaying correctly sometimes (#449, thanks @bogdomania!).
When history playback is disabled, the /HISTORY command now says so instead of silently failing (#429, thanks @bogdomania!).
The /HOSTSERV ON/OFF commands now tell you when you don’t have a vhost (#404, thanks @bogdomania!).
When operators use the /SANICK command, the snomask now says which operator did it instead of saying the target changed their nickname themselves (#360, thanks @bogdomania!).

Added

IP cloaking is now supported (see the manual for details) (#108).
Users can now attach multiple clients to the same nickname (see the manual for details) (#403).

[1.0.0] - 2019-02-24

We’ve finally made it to v1.0.0! With this release, our list of need-to-haves is rounded out, and we reckon the software’s ready for production use in smaller networks. slingamn and I have been working with our contributors and translators to prepare a cracker of a release. Thanks to @csmith our Docker builds have been updated, with automatic rebuilds as we develop the software. Thanks to @bogdomania our translation workflow has been improved a lot.

Better detection of confusing nick/account/channel names.
User-customizable nickname protection methods.
An account-only mode in which all clients must have an account and login to it (using SASL) before they can join the server.

Thanks to Mauropek, @modinfo, @bogdomania, @Shillos, Tony Chen, and Remini for adding new translations. Thanks to @Ascrod, @bogdomania, @csmith, @jesopo, @jwheare, @remini1998, @enckse, and @iNecas for finding bugs and/or writing new features.

oragono.io/maxline capability was accidentally disabled, and is now re-enabled.
oragono genpasswd now works when piping input in (fixes Docker installs).
PRIVMSG: Messages sent to multiple clients (such as channel messages) now share the same timestamp (previously each client got a very slightly different time).
WHOIS: Now responds properly for NickServ, ChanServ, etc.
Channel names with right-to-left characters are now casefolded correctly (thanks to @remini1998!).
Fixed handling of CIDR width in connection limiting/throttling.

Command-line parsing was upgraded to match modern best practices (thanks to @iNecas!).
Direct responses to client commands are now sent “synchronously”, bypassing the sendq.
Logging system optimised.
Services handlers refactored.
Translations are now sent to/PR’d from CrowdIn automagically as we develop the software.

[0.12.0] - 2018-10-15

There’s been a host of changes in the past six months, and this Halloween release has a number of very useful improvements.

For example, passwords are now hashed in a much better way than we did it before (jlatt’s original method back from Ergonomadic was the right way to do things), the database now auto-upgrades for you when it detects a new version, thanks to Slingamn we now have vhosts, and there’s been a ton of rewrites under-the-hood to improve stability and performance.

If you have any trouble with this release, please let us know with an issue on our tracker, or by talking to us in #oragono on Freenode.

Thanks to slingamn for a lot of heavy lifting this release and to vilmibm for contributing a documentation fix!

Config Changes

Added

Added database auto-upgrades.
Added new subcommands to ChanServ including:
- AMODE to allow setting persistent channel modes for users.
- DROP to unregister a channel.

Changed

ChanServ and NickServ now show in their help output when commands have been disabled.
Channel keys and modes are now stored for registered channels.
Client capability handling rewritten under-the-hood.
Disabled services commands now show as disabled (rather than being completely hidden).
Many under-the-hood optimisations (thanks @slingamn!).

Removed

Removed StackImpact debug support, as we don’t find it useful these days.

Fixed

Fixed LUSERS to make it display correct client count and output correct params (thanks @moortens!.
Fixed PROXY support for IPv6 clients.
Fixed SAMODE crash when using it on a channel you’re not joined to.
Fixed WHOIS so that RPL_WHOISACCOUNT is now sent correctly.
Fixed fakelag timing to better match expected values.
Fixed issue where incoming and outgoing private messages were being incorrectly modified (a space was being added to the end) due to a bug with our protocol handling.
Fixed password hashing method, with existing passwords being auto-upgraded to use the new method.

[0.11.0] - 2018-04-15

And v0.11.0 finally comes along! This release has been in the works for almost four months now, with an alpha and beta helping square away the issues.

We’re adding a lot of features to improve debugging, better support international users, and make things better for network administrators. Among the new features, you can use the LANGUAGE command to set a custom server language (see our CrowdIn to contribute), expose a debugging pprof endpoint, reserve nicknames with NickServ, and force email verification for new user accounts. On the improvements side we have a CAP REQ fix, and we now have a manual that contains a nice overview of Oragono’s documentation.

If you have any trouble with this release, please let us know with an issue on our tracker, or by talking to us in #oragono on Freenode.

Thanks a bunch to everyone for the help with this release – especially to our translators and to Slingamn for being an awesome co-maintainer!

Added a manual to our documentation! This is primarily where we’ll be adding user-facing information and instructions from now on.
Added current running git commit to the sent version string.
Added fakelag, so that the server can slow down clients hitting it too aggressively. Disabled by default while we work out the kinks and the specific settings (thanks @slingamn!).

Added user modes, including:
- B: Mark yourself as a bot, and display that you’re a bot in WHOIS.

Changed

genpasswd now requires that you confirm the input passphrase.
Message IDs are now much shorter and easier to read – down from 39 characters to 16 while preserving a very similar gaurantee of uniqueness (thanks @prawnsalad for bringing up this issue).

Fixed

We now correctly suspend registration when receiving a CAP REQ, as per the spec.
We now properly cut off clients who try to send us too much data at once.

[0.10.3] - 2017-12-26

This patch fixes a couple bugs, updates cap/isupport token names in response to spec changes, and allows unprivileged users to list channel bans. Ah, DLINE and KLINE also store oper names, so you can see who set those pesky bans later on!

Overall, a fairly standard patch that just improves things. No config changes, no database changes.

Also, Merry Christmas and Happy Holidays!

Added

DLINE/KLINE: We now save the name of whichever oper set the ban (and display it later).

Changed

draft/maxline capability is now oragono.io/maxline.
WHO: First parameter now must be a mask or channel name, cannot be ommitted.
Casemapping is now advertised using the UTF8MAPPING token, matching the new spec changes.
We now allow unprivileged users to list channel bans.

Fixed

Fixed a bug around removing channel bans.
Fixed a client timeout bug.

[0.10.2] - 2017-11-13

This patch release fixes a bunch of crashes that were introduced in the last release, 0.10.1.

If you have 0.10.1 running, replace it with this release.

Security

Fixed lots of miscellaneous crashes.

[0.10.1] - 2017-11-09

This patch release of Oragono fixes a fairly big channel mode bug, where users could set channel modes when they weren’t actually allowed to.

Config Changes

recover-from-errors key added under debug, which enables recovery from client-caused errors (at the cost of possible server instability).

Security

Clients could set channel modes when they weren’t supposed to be able to.

Added

We now allow recovering from client-caused panics.

Fixed

SAMODE now lists other users’ modes.
Removed some possible crashes and races.

[0.10.0] - 2017-10-23

There has been a bunch of new changes in this release! From sts being ratified to supporting WEBIRC to rewriting a whole lot of our internals, 0.10.0 represents a real step forward in terms of where Oragono’s going.

In addition to the new features, this issue fixes a bunch of fairly large bugs (such as an errant INVITE being able to crash the server, the +mRchannel modes not working at all, and making rehashing safer).

I’d like to thank @slingamn for really contributing a lot in this release! He’s done a whole bunch of the internal work, cleaned up the code, and in general just been a great help while developing. Running Oragono on an actual network has really helped find and track down some serious bugs, and lead us to some much-needed improvements.

Config Changes

motd-formatting key added under server, which supports MOTD formatting characters.
rest-api section removed from server (since we no longer support the Rest API).
webirc section added under server, which specifies the gateways can use the WEBIRC command.
ws-listen key removed from server (since we no longer support websocket ports).
Connection limits and connection throttling has become more relaxed by default.

Security

INVITE: Fixed a server crash when sending an invite for a channel that doesn’t exist (thanks @josephbisch for telling me about the bug!).

Added

Added support for the WEBIRC command, allowing gateways to connect.
We now list XLINEs with DLINE LIST and KLINE LIST.
We now support using escaped formatting codes in the MOTD (tl;dr easy colors, bold and italics).

Changed

D-LINE and K-LINE code is now cleaner under the hood and less likely to crash.
Ident (looking up usernames) now times out a whole lot quicker, meaning you connect to the server more quickly.
IRCv3 capability draft/sts has been renamed to sts, since it’s now been ratified.
Rehashing is now safer.
Server opers could always speak on channels, even when they shouldn’t be able to. Now they aren’t above the law.

Removed

Removed the draft/message-ids cap since… it doesn’t actually exist. The feature is now enabled by default when clients request the draft/message-tags-0.2 capability, as written in the Message IDs spec.
Removed websocket support (conflicted with existing larger IRCd’s implementations and not used by any real clients).
REST API has been removed, until we can build up the web interface in parallel with it.

Fixed

AWAY was sending an incorrect mode string, and now sends the correct mode string (thanks @jwheare for pointing this out).
Fixed some bugs with our MONITOR implementation which meant we weren’t returning the right info to clients.
The Moderated (+m) and RegisteredOnly (+R) channel modes could not be set. Now they can be set.

[0.9.1] - 2017-09-28

This is a patch release to fix compatibility with Irssi and resolve some issues! Thanks very much @dequis, @slingamn and squigz for the help and for bringing up the issues.

Added

Allow the MODE b syntax, which certain clients use to check lists.

Changed

QUIT: We now send the actual quit message to other users.

Fixed

Fix incorrectly forwarding AWAY messages to clients without away-notify.
Fix incorrect login check which prevented account registration.
Fix ERR_NOSUCHNICK numerics (we weren’t sending the nick correctly).

[0.9.0] - 2017-09-25

So many fixes! You can now set the default modes for new channels, use HAProxy again, use the umode +R to protect yourself against unwanted PMs, and we now warn on configurations/setups that look incorrect!

In addition, this release makes testing easier, makes sure we better adhere to the SASL specification and also removes some memory leaks around the place. All in all, just a solid upgrade and less bugs across the board.

Config Changes

Added allow-multiple-per-connection flag under accounts/registration, which can be used for account setup by testing software. Never enable it in production.
Added default-modes key under channels, which is a standard modestring that’s applied to new channels.
Added proxy-allowed-from key under server, which is a list of hostnames/IPs that the HAProxy PROXY command can be used from.

Security

Clients could use a nickname that isn’t sane. This has the possibility of allowing clients to subvert our admin commands and monitoring features.

Added

Added a warning if the server’s not listening on a TLS port or if it’s not listening for TLS connections on port 6697.
Added a warning if you’re trying to run from source or an otherwise unreleased version.
Added INFO.md document to better explain the design decisions behind Oragono, exactly how to rehash, etc.
Added support for HAProxy’s PROXY v1 command, useful for certain installations.
Added user modes, including:
- R: Only receive private messages and notices from other registered users.

Fixed

Fixed a bug where certain clients couldn’t connect as we were incorrectly rejecting their valid PTR record (thanks @slingamn!).
Fixed a crash around monitoring clients.
Fixed a memory leak in our socket code when clients disconnect.
Fixed a SASL bug that resulted in certains clients getting caught in a cycle of trying (and failing) to abort authentication.
Fixed an instance where clients could use a nickname that isn’t sane (thanks @euank!).
Fixed an issue where certain clients who connect incorrectly would stay connected (thanks @euank!).
Fixed how we handle particularly unique Unicode strings (we now ensure they stabilize while casefolding).
Fixed some issues around rehashing, where listeners wouldn’t rehash in time and could crash (thanks @slingamn!).

[0.8.2] - 2017-06-30

Just a patch release to fix a bug! The bug that’s been fixed prevented you from modifying channel privilidges at all, which isn’t great. With this release, now you can do so again!

This is one I’m gonna have to add to the testcases, to make sure it doesn’t happen again.

Fixed

Fixed a bug where users could not give other users operator/halfop/voice in channels.

[0.8.1] - 2017-06-26

Lots of quality-of-life fixes, improved oversight for opers, and a proposed channel renaming command!

With this release, we’re moving to a proper Github organisation, becoming more consistent with other IRCds, and introducing a bunch more snomasks. In addition, when setting DLINE and KLINE bans, you can also kill all clients who match the ban by supplying the parameter ANDKILL when you set the ban.

Channel LIST filtering is now more useful, and I’ll keep expanding this in future releases. As well, there’s been some useful extensions to WHOIS, and a bug with SANICK fixed thanks to @lbeziaud. @enckse has also added Oragono to the Arch AUR, to make it easier to install on that distro.

Thanks to everyone for suggesting improvements and reporting issues! There’s a lot to do as we move forward, and I have a pretty decent plan of where to go next.

Added

Added proposed channel rename capability draft/rename.
Send a bunch more server notice masks, now including:
- j: Channel registration.
- k: Kills, including those resulting from DLINEs and KLINEs.
- n: Nick changes.
- o: Clients opering-up.
- q: Clients quitting.
- u: Account registration and login.
- x: Setting and removing DLINE/KLINE.

Changed

DLINE and KLINE: Added ANDKILL parameter to also kill all clients that match the ban.
LIST: Implement extended list conditions U (which filters the channels by user count).
Renamed a number of dependency libraries, and changed Oragono to its’ own organisation (only useful if you’re building Oragono from source).
WHOIS: Show the target’s real IP address if you’re whoising yourself or you’re an oper.
WHOIS: Show whether the target has connected securely using TLS.

Removed

Removed the JOIN 0 command (matching what InspIRCd has done here), since this is easily abusable.

Fixed

SANICK works properly now (thanks @lbeziaud!).

[0.8.0] - 2017-05-09

Debugging! Fixes! Better realtime monitoring!

This release isn’t too exciting, but packs large improvements to how we handle floods and similar issues. As well, the introduction of snomasks (take a look at /HELPOP snomasks) should help opers keep a basic view over their server during use. Only the "c" (connects) snomask is active right now, but others will be added and extended in future releases.

Config Changes

Added debug section containing additional debug settings.
Added modes key on oper config, for setting modes on oper-up.
Added ability to log to stdout in logger methods.

Added

Added ability to log to stdout.
Added ability to use StackImpact profiling.
Added initial server notice masks (snomasks).

Changed

Socket code rewritten to be a lot faster and safer.
Updated account registration to use the latest proposed syntax (now being /ACC REGISTER instead of /REG CREATE).

Fixed

Clients now timeout properly if they don’t complete connection registration.
Word wrapping (with draft/maxline) no longer randomly drops characters.

[0.7.2] - 2017-04-17

This is a patch release of Oragono to fix discovered bugs and crashes. I’ll also be implementing some more stringent checks before pushing releases after this, to ensure these same sort of bugs don’t happen again.

Security

Fixed a bug where any user joining an unregistered channel was given chanop status (thanks @vegax87).

Fixed

Fixed a number of various crashes and races.

[0.7.1] - 2017-03-28

This is a quick patch release of Oragono to work around a discovered bug.

Security

Fixed a bug where non-logged in users could register channels. Bleh.

[0.7.0] - 2017-03-27

This release brings channel registration with ChanServ, logging improvements, and a whole host of improvements across the board.

Thanks to a suggestion by dp- on our channel (#oragono on Freenode), the socket handling code has been overhauled to allow for a larger number of more stable connections. As well, improved testing has brought with it a bunch of strange hang and crash fixes, which means that Oragono should be more stable than ever.

Channel registration is really cool. Essentially, you register the channel with /CS REGISTER as you would on any network, and then all topic changes, the +b/+e/+I lists, and your founder status, are all remembered and re-applied when the server’s restarted.

Config Changes

channels section added to control channel registration.
logging key under server removed, replaced with logging section.
max-sendq key added under server.
registration and authentication-enabled keys moved under accounts section.
samode capability added to oper capabilities.
sts section added under server.

Added

Added ChanServ service, to allow channel registration.
Added USERHOST command (thanks @vegax87).
Added SAMODE command.
Added draft IRCv3 capability draft/sts.

Changed

DLINE and KLINE now let you specify years, months and days (e.g. 1y12m30d) in durations.
Logging is now much more useful, displays colours and can log to disk.
Socket handling has been rewritten, which means we should support more connections more effectively (thanks dp- for the suggestion!).

Fixed

Fixed a bunch of small hangs and crashes.
Fixed an account issue where clients could login to multiple accounts at once.
Fixed an issue where server times were incorrect (thanks @martinlindhe!).
Fixed halfops not being able to talk during moderated mode (+m).
Fixed issues that prevented rehashing after the first rehash had gone through successfully.
Fixed the inability to view channel ban, ban exception, and invite exception lists.

[0.6.0] - 2017-01-19

We’ve added a ton of new features in this release! Automated connection throttling, the ability to KLINE, updated casemapping and line-length specifications.

I’ve also started including a new section in the changelog called Config Changes, which should help you find what you need to update across releases.

Config Changes

enabled key added under the connection-limits section.
connection-throttling section added under server.
linelen section added under limits.

Added

Added ARM build (for Raspberry PIs and similar).
Added automated connection throttling! See the new connection-throttling section in the config.
Added KLINE and UNKLINE commands. Complementing DLINE’s per-IP and per-network bans, this lets you ban masks from the server.
Added LUSERS command (thanks @vegax87).
Added draft IRCv3 capabilities draft/message-tags-0.2 and draft/message-ids.
Added proposed IRCv3 capability draft/maxline.

Changed

Changed casemapping from “rfc7700” to “rfc7613”, to match new draft spec.
Connection limits can now be freely enabled or disabled. If updating, check the new enabled flag under the connection-limits section of the config.

Fixed

Fixed an issue where UNDLINE didn’t save across server launches.
Removed several race conditions which could result in server panics.
WHOIS: Multiple channels now appear in a single reply (thanks @vegax87).

[0.5.0] - 2016-12-10

This release includes a ton of fixes, as well as the ability to ban IP addresses from your network with the DLINE command!

As well, there are some major fixes with the libraries Oragono depends on, which fix various DoS attacks, crashes and timeouts. In short, this release is more stable and fixes a bunch of issues.

This release also updates the database, so be sure to run the oragono upgradedb command.

Added

Added ability to ban IP addresses and networks from the server with the DLINE and UNDLINE commands.
Added alpha REST API (intended primarily for use with a future web interface to manage accounts, DLINEs, etc).

Changed

Database upgraded to make handling accounts simpler.
Only give chanop (@) on channel join, not channel founder (~). We’ll do channel founder and all on registered chans only.

Fixed

Fixed a bunch of bugs around setting nicknames on join.
Fixed crash when using STATUSMSG-like messaging.
Fixed crash with gIRC-Go ircmsg library we depend on.
Fixed not sending MODE changes to all clients in a channel.
Fixed timeout issue with go-ident library we depend on (which caused hangs on connection).
Prevented a DoS related to lots of clients connecting at once.
Removed races around setting and changing NICKs, to be more safe.
Send channel NOTICEs properly.

[0.4.0] - 2016-11-03

This release packs a more extensive oper privelege framework, bugfixes for capabilities/modes, support for new RP commands and more RPL_ISUPPORT tokens. In general, a bunch of new features and bugfixes to make using Oragono more smooth.

Added

Added automatic client connection limiting, similar to other IRCds.
Added operator classes, allowing for more finely-grained permissions for operators.
Added roleplaying commands, both inside channels and between clients.
Length of channel mode lists (ban / ban-except / invite-except) is now restricted to the limit in config.
Support MAXLIST, MAXTARGETS, MODES, TARGMAX in RPL_ISUPPORT.
Added support for IRCv3 capability chghost.

Changed

In the config file, “operator” changed to “opers”, and new oper class is required.

Fixed

Fixed being able to change modes when not an operator.
Fixed bug where HELP wouldn’t correctly display for operators, and added more help topics.
Fixed bug where you would always have certain capabilities enabled.
Fixed display of large MONITOR lists.

[0.3.0] - 2016-10-23

We now support dynamically reloading the config file, along with some new IRCv3 capabilities and some fixes.

The REHASH changes are fairly extensive here, but should now be stable (this also fixes a denial of service possible with the old code).

Security

Prevent a denial of service where the server would stop accepting connections.

Added

Added REHASH command.
Added ability to message channel members with a specific privelege (i.e. support for STATUSMSG).
Added ability to enable and disable SASL.
Added support for IRCv3 capabilities cap-notify and echo-message.

Changed

Server operators no longer have permissions to do everything in channels.

Fixed

MODE: Fixed issue where channel privelege changes returned incorrectly.

[0.2.0] - 2016-10-16

Improved compatibility, more features.

Now comes with a new proper Unicode-capable casemapping and integrated help!

Added

Added integrated help (with the /HELP command).
Added support for IRCv3.2 capability negotiation including CAP values.
Added support for IRCv3 capabilities account-notify, invite-notify, monitor, sasl, and draft capability message-tags as draft/message-tags.

Changed

Casemapping changed from custom unicode mapping to preliminary rfc7700 mapping.

Removed

Removed channel persistence with the +P mode (not too useful as currently implemented, to be replaced later).
Removed the PROXY command (breaks our TLS user mode, and our integrated support for TLS should be fine).

[0.1.0] - 2016-09-18

Initial release of Oragono!

Security

PROXY command is now restricted appropriately.
Nicknames, usernames and channel names that break the protocol are no longer allowed.
Default channel modes set to restrict new channels more appropriately by default.

Added

YAML config file format.
buntdb key-value store for persistent data.
Native SSL/TLS support (thanks to @edmand).
Ability to generate testing certificates from the command line.
Support for looking up usernames with ident on client connection.
RPL_ISUPPORT numeric as advertised by most other IRCds today.
Ability to parse complex mode change syntax commonly used these days (i.e. +h-ov dan dan dan).
User mode for clients connected via TLS (+Z).
Ability to register and login to accounts (with passphrase or certfp).
Added support for IRCv3 capabilities account-tag, away-notify, extended-join, sasl, server-time, and userhost-in-names.

Changed

Channel creator (O) privilege changed to founder/admin/halfops (qah) privileges.
Private (+p) channel mode changed to secret (+s), to match what’s used by servers today.
Default channel modes changed to (+nt), matching most other IRCds.
CLI commands and arguments made more consistent with typical software.
Usernames set by the USER command now start with "~" (to work with new ident support).
Renamed ONICK command to SANICK to be more consistent with other IRCds.
Made maximum nickname and channel name lengths configurable.
Made maximum WHOWAS entries configurable.

Removed

Removed gitconfig configuration format [replaced with YAML].
Removed sqlite database [replaced with buntdb key-value store].
Removed THEATER command (it broke and I’m not that interested in putting the work in to get it working again with the aim of this project. PRs accepted).

Fixed

Fixed clients no longer being able to send commands after a single command errored out.
CAP: Registration is now properly suspended during CAP negotiation.
CAP: Remove CAP CLEAR (recommended in IRCv3 3.2), and allow capability negotiation after registration.
MODE: Fixed <modestring> evaluation (we were parsing all ungrabbed parameters as a modestring, when it is actually only the first param).
MODE: New-style mode change syntax (with both adding and removing modes in a single MODE command) is now parsed properly.
MOTD: Now store MOTD in-memory rather than on-disk, and don’t limit it to 80 characters per line (not required with today’s servers or clients).
NICK: Restrict nicknames that break the protocol.
USER: Restrict usernames that break the protocol.
PROXY: Restrict to specified hostnames only.
WHOIS: Include the required <nick> param on RPL_ENDOFWHOIS.
WHOIS: Hide hidden channels in WHOIS responses.
