[2.1.0-rc1] - 2020-05-25

We’re pleased to be publishing the release candidate for 2.1.0 (the official release should follow in a week or so).

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, @jwheare, @k4bek4be, @kula, @kylef, @Mitaka8, @petteri, @PizzaLover2007, @prawnsalad, @RyanSquared, savoyard, and @xPaw for reporting issues, and to TODO: TRANSLATORS 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 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).

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!)

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 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 redundant /INVITE commands not sending 443 ERR_USERONCHANNEL (#842, thanks @hhirtz!)
• Fixed /NICKSERV REGISTER response displaying mailto: out of context (#985, thanks @eklitzke!)
• Fixed HostServ approval and rejection notices being sent from the wrong source (#805)
• Error messages for invalid TLS certificate/key pairs are now more informative (#982)
• 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 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)
• /CHANSERV AMODE now takes immediate effect (#729)
• The channel founder can now take any action that would require channel privileges without actually having the +q mode (#950, #998)
• Account unregistration now always disconnects the client (#1028)
• Fakelag is now temporarily disabled during the sending of a draft/multiline message batch (#817)
• Failed attempts to join a +R channel now send 477 ERR_NEEDREGGEDNICK (#936, thanks @PizzaLover2007, @jesopo!)
• Channels with persistent history can no longer be renamed with /RENAME (#827)
• The self-signed certificate generation command oragono mkcerts now generates a 2048-bit RSA certificate, instead of a NIST P-521 ECDSA certificate (#898)
• 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 /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 /HISTSERV FORGET for deleting all history messages associated with an account (see the config option history.retention.enable-account-indexing) (#858)
• Added /HISTSERV EXPORT for exporting all history messages associated with an account as JSON. This can be used at the user’s request for regulatory compliance reasons (see the config option history.retention.enable-account-indexing) (#858)
• Added support for logging legacy clients into accounts via the PASS command, with the account:password syntax used by Freenode. To enable this feature, set accounts.login-via-pass-command to true. (#1020, thanks @jlnt!)
• Added /NICKSERV ERASE as an escape hatch for operators, allowing an account to be erased and re-registered (#793)
• Added support for playing back MODE and TOPIC messages in history (#532)
• Added conventional.yaml, a version of the config file that provides a more traditional IRC experience. We recommend a config file based on oragono.yaml for production networks, and one based on conventional.yaml for IRCv3 conformance testing. (#918)
• Added an optional global throttle on the creation of new accounts (#913)
• 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!)

[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:

1. 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.
2. 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:

1. 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
2. Rehash your server, confirming that the new config file is valid for for the previous version of the server
3. Upgrade your oragono binary to the new 2.0.x version and restart your server
4. 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

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).

[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:

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

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).

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

• Improved display of NickServ timeout warnings in some clients (#572, thanks @bogdomania!)
• LUSERS output is now sent at the end of connection registration (#526)
• Fixed operators not being able to WHOIS some Unicode nicknames (#331, thanks @bogdomania!)
• Fixed RESUME not clearing the BRB reason (#592, thanks @jesopo!)
• 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

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).

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.

• 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!).
• History playback now includes messages that the user sent themselves (especially useful with the new bouncer-like capabilities) (#487).

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).

• Fixed portability issues with 32-bit architectures (#527).

[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.

Highlights include:

• Optional support for storing and replaying message history with the draft/resume-0.3 capability, the draft IRCv3 CHATHISTORY command, and a custom HISTORY command.
• 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.

• Exemption lists now accept localhost as a value, meaning any loopback IPV4, loopback IPV6, or unix domain address.
• Logging type server has been added, replacing the startup, rehash, and shutdown types.
• The default logging configuration now logs to stderr only, rather than to both stderr and a file.
• We no longer listen on port 6668 by default (this fixes Docker installs).

• Updated all translation files (thanks to our amazing translators!).
• Updated proposed IRCv3 capability draft/resume to draft/resume-0.3.
• When nick ownership is enabled, users can now select which enforcement mechanism to use with their nickname.

Fixed

• INVITE: Fixed bug where invited users could not join the channel they were invited to (thanks to @unendingpattern!).
• 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.

Internal Notes

• DLINE and KLINE refactored, and expired bans are now removed from the database.
• 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

• allow-multiple-per-connection key removed from accounts.
• autoupgrade key added under datastore, specifying whether to upgrade to new database versions automatically.
• bcrypt-cost key added under accounts, to control how strongly account passwords are hashed.

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!).
• Rehashing is now more consistent and safe.

Removed

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

Fixed

• 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!

Config Changes

• callbacks section added under accounts/registration, configuring our new email verification (disabled by default).
• fakelag section added, configuring our new fakelag implementation.

• 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!).

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.
