We're pleased to be publishing the release candidate for 2.8.0 (the official release should follow in a week or so).
This release contains many fixes and enhancements, plus one major user-facing feature: user-initiated password resets via e-mail (#734).
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 a database change. If you have `datastore.autoupgrade` set to `true` in your configuration, it will be automatically applied when you restart Ergo. Otherwise, you can update the database manually by running `ergo upgradedb` (see the manual for complete instructions).
As part of this release, our official Docker images will move from Docker Hub to [the GitHub Container Registry at ghcr.io](https://ghcr.io); more details will be forthcoming with the final release.

* Added `accounts.registration.email-verification.timeout` to impose a timeout on e-mail sending; the recommended default value is `60s` (60 seconds) (#1741)
* Added `server.suppress-lusers` to allow hiding the LUSERS counts (#1802, thanks [@eskimo](https://github.com/eskimo)!)
### Security
* Added `accounts.registration.email-verification.timeout` to impose a timeout on e-mail sending; the recommended default value is `60s` (60 seconds) (#1741)
### Added
* Added user-initiated password resets via email (#734). This requires e-mail verification of accounts, and must additionally be enabled explicitly: see the `email-verification` block in `default.yaml` for more information.
* Added the `draft/extended-monitor` capability (#1761, thanks [@delthas](https://github.com/delthas)!)
* When doing direct sending of verification emails, make email delivery failures directly visible to the end user (#1659, #1741, thanks [@tacerus](https://github.com/tacerus)!)
* For operators, `NS INFO` now shows the user's email address (you can also view your own address) (#1677, thanks [@ajaspers](https://github.com/ajaspers)!)
* Operators with the appropriate permissions will now see IPs in `/WHOWAS` output (#1702, thanks [@ajaspers](https://github.com/ajaspers)!)

* Added support for the `SCRAM-SHA-256` SASL authentication mechanism (#175). This mechanism is not currently advertised in `CAP LS` output because IRCCloud handles it incorrectly. We also [recommend against using SCRAM because of its lack of genuine security benefits](https://gist.github.com/slingamn/3f2fed196df5ef14d1316a1ffa9d59f8).
*`/UBAN LIST` output now includes the time the ban was created (#1725, #1755, thanks [@Mikaela](https://github.com/Mikaela) and [@mogad0n](https://github.com/mogad0n)!)
* Added support for running as a `Type=notify` systemd service (#1733)
* Added a warning to help users detect incorrect uses of `/QUOTE` (#1530)
### Fixed
* The `+M` (only registered users can speak) channel mode did not work; this has been fixed (#1696, thanks [@Mikaela](https://github.com/Mikaela)!)
* A channel `/RENAME` that only changed the case of the channel would delete the channel registration; this has been fixed (#1751, thanks [@Mikaela](https://github.com/Mikaela)!)

* Fixed parameter sent with `696 ERR_INVALIDMODEPARAM` (#1773, thanks [@kylef](https://github.com/kylef)!)
* Fixed handling of channel mode `+k` with an empty parameter (#1774, #1775, thanks [@ProgVal](https://github.com/ProgVal)!)
*`WHOWAS` with an empty string as the parameter now produces an appropriate error response (#1703, thanks [@kylef](https://github.com/kylef)!)

* Fixed buggy behavior when `+i` is configured as a default mode for channels (#1756, thanks [@Mikaela](https://github.com/Mikaela)!)
* Fixed issues with `channels.operator-only-creation` not respecting `/SAJOIN` or always-on clients (#1757)
* Protocol-breaking operator vhosts are now disallowed during config validation (#1722)
* Fixed error message associated with `/NS PASSWD` on a nonexistent account (#1738, thanks [@Mikaela](https://github.com/Mikaela)!)
* Fixed an incorrect `CHATHISTORY` fail message (#1731, thanks [@ProgVal](https://github.com/ProgVal)!)
* Fixed a panic on an invalid configuration case (#1714, thanks [@erikh](https://github.com/erikh)!)
### Changed
* Upgraded the `draft/register` capability to the latest [`draft/account-registration`](https://github.com/ircv3/ircv3-specifications/pull/435) iteration (#1740)
* Unregistered users with `+v` or higher can now speak in `+R` (registered-only) channels (#1715, thanks [@Mikaela](https://github.com/Mikaela) and [@ajaspers](https://github.com/ajaspers)!)

* Added an s6 init script (#1786, thanks [@majiru](https://github.com/majiru)!)
We're pleased to be publishing Ergo 2.7.0, our first official release 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](https://github.com/ajaspers) and [@jesopo](https://github.com/jesopo) for contributing patches, to [@ajaspers](https://github.com/ajaspers), [@ChrisTX](https://github.com/ChrisTX), [@emersion](https://github.com/emersion), [@jwheare](https://github.com/jwheare), [@kylef](https://github.com/kylef), [@Mikaela](https://github.com/Mikaela), [@mogad0n](https://github.com/mogad0n), and [@ProgVal](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/ProgVal), [@jwheare](https://github.com/jwheare), and [@Mikaela](https://github.com/Mikaela)!)
* Fixed a case where channels would remain visible in `/LIST` after unregistration (#1619, thanks [@ajaspers](https://github.com/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](https://github.com/ajaspers)!)
* Fixed a case where the `REGISTER` command would emit an invalid error message (#1633, thanks [@ajaspers](https://github.com/ajaspers)!)
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:
1. 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.)
2. 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](https://github.com/ajaspers) for reporting the issue.
### Security
* Fixed and documented potential authentication bypasses via the `REGISTER` command (#1634, thanks [@ajaspers](https://github.com/ajaspers)!)
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 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](https://github.com/ajaspers) and [@Mikaela](https://github.com/Mikaela) for contributing patches, to [@aster1sk](https://github.com/aster1sk), [@emersion](https://github.com/emersion), [@eskimo](https://github.com/eskimo), [@hhirtz](https://github.com/hhirtz), [@jlu5](https://github.com/jlu5), [@jwheare](https://github.com/jwheare), [@KoraggKnightWolf](https://github.com/KoraggKnightWolf), [@kylef](https://github.com/kylef), [@Mikaela](https://github.com/Mikaela), [@mogad0n](https://github.com/mogad0n), [@ProgVal](https://github.com/ProgVal), and [@szlend](https://github.com/szlend) for reporting issues and helping test, and to our translators for contributing translations.
* 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](https://github.com/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](https://github.com/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](https://github.com/mogad0n)!)
### Fixed
* Fixed an edge case in line buffering that could result in client disconnections (#1572, thanks [@ProgVal](https://github.com/ProgVal)!)
* Upgraded buntdb, our embedded database library, fixing an edge case that could cause data corruption (#1603, thanks [@Mikaela](https://github.com/Mikaela), [@tidwall](https://github.com/tidwall)!)
* Improved compatibility with the published `draft/register` specification (#1568, thanks [@ProgVal](https://github.com/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](https://github.com/ProgVal)!)
* Fixed `znc.in/playback` commands causing client disconnections when history is disabled (#1552, thanks [@szlend](https://github.com/szlend)!)
* 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](https://github.com/kylef)!)
* Auto-away behavior now respects individual clients; the user is not considered away unless all clients are away or disconnected (#1531, thanks [@kylef](https://github.com/kylef)!)
* Direct messages rejected due to the `+R` registered-only usermode now produce an error message (#1064, thanks [@KoraggKnightWolf](https://github.com/KoraggKnightWolf), [@ajaspers](https://github.com/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](https://github.com/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](https://github.com/jlu5)!)
* User passwords may no longer begin with `:` (#1571)
* Improved documentation of `CS AMODE` and `NS UNREGISTER` (#1524, #1545, thanks [@Mikaela](https://github.com/Mikaela)!)
* Disabling history disables history-related CAPs (#1549)
### Added
* Implemented the new [CHATHISTORY TARGETS](https://github.com/ircv3/ircv3-specifications/pull/450) API for listing direct message conversations (#1592, thanks [@emersion](https://github.com/emersion), [@hhirtz](https://github.com/hhirtz), [@jwheare](https://github.com/jwheare), [@kylef](https://github.com/kylef)!)
* Implemented the new [IRC-over-websockets draft](https://github.com/ircv3/ircv3-specifications/pull/342), adding support for binary websockets and subprotocol negotiation (#1558, thanks [@jwheare](https://github.com/jwheare)!)
* Implemented the new [bot mode spec](https://github.com/ircv3/ircv3-specifications/pull/439) (#1562)
* Implemented the new [forward mode spec](https://github.com/ircv3/ircv3-specifications/pull/440) (#1612, thanks [@ProgVal](https://github.com/ProgVal)!)
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](https://github.com/jlu5), [@kylef](https://github.com/kylef) and [@Mikaela](https://github.com/Mikaela) for contributing patches, to [@bogdomania](https://github.com/bogdomania), [@eskimo](https://github.com/eskimo), [@happyhater](https://github.com/happyhater), [@jlu5](https://github.com/jlu5), [@kylef](https://github.com/kylef), [@LukeHoersten](https://github.com/LukeHoersten), [@Mikaela](https://github.com/Mikaela), [@mogad0n](https://github.com/mogad0n), [@robinlemon](https://github.com/robinlemon), and [@vertisan](https://github.com/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](https://github.com/robinlemon)!)
* Added `accounts.multiclient.always-on-expiration`, allowing always-on clients to be timed out for inactivity (#810, thanks [@bogdomania](https://github.com/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](https://github.com/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](https://github.com/Mikaela)!)
* Added `server.override-services-hostname`, allowing the hostname of NickServ, ChanServ, etc. to be overridden (#1407, thanks [@Mikaela](https://github.com/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](https://github.com/Mikaela)!)
### Security
* Improved validation of names and encodings for client-only tags (#1385)
* Improved auditability of sensitive operator actions (#1443, thanks [@mogad0n](https://github.com/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](https://github.com/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](https://github.com/jlu5), [@kylef](https://github.com/kylef), and [@Mikaela](https://github.com/Mikaela)!)
* Fixed incorrect processing of color code escapes in MOTD files (#1467, thanks [@mogad0n](https://github.com/mogad0n)!)
* STS is no longer advertised to Tor clients (#1428, thanks [@Mikaela](https://github.com/Mikaela)!)
* Fixed HELP/HELPOP numerics not including the nick as an argument (#1472, thanks [@kylef](https://github.com/kylef)!)
* Made connection registration snomasks less confusing (#1396, thanks [@eskimo](https://github.com/eskimo)!)
* Fixed duplicated nicks in `KLINE` response (#1379, thanks [@mogad0n](https://github.com/mogad0n)!)
* The `RELAYMSG` tag name is now `draft/relaymsg`, conforming to the amended draft specification (#1468, thanks [@jlu5](https://github.com/jlu5)!)
* Fixed `SAJOIN` not sending a `MODE` line to the originating client (#1383, thanks [@mogad0n](https://github.com/mogad0n)!)
* Improved consistency of message sources sent by `CS AMODE` (#1383, thanks [@mogad0n](https://github.com/mogad0n)!)
* Fixed duplicated `JOIN` line sent to some clients using the `draft/resume-0.5` extension (#1397, thanks [@kylef](https://github.com/kylef)!)
* Added a warning that MySQL cannot be enabled by rehash (#1452, thanks [@Mikaela](https://github.com/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](https://github.com/mogad0n)!)
* The characters `<`, `>`, `'`, `"`, and `;` are no longer allowed in nicknames (previously registered account names containing these characters are still accepted) (#1436, thanks [@happyhater](https://github.com/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](https://github.com/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](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#subprotocols); 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](https://github.com/robinlemon)!)
* Added support for `/JOIN 0` (part all channels), requiring a confirmation code (#1417, thanks [@Mikaela](https://github.com/Mikaela)!)
* Added support for grouped nicknames as SASL usernames (#1476, thanks [@eskimo](https://github.com/eskimo)!)
* Added history support for `INVITE` (#1409, thanks [@Mikaela](https://github.com/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](https://github.com/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](https://github.com/LukeHoersten)!)
### Internal
* Added caching for serialized messages (#1387)
* Improved memory efficiency of line reading (#1231)
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](https://github.com/moortens)!)
* [draft/relaymsg](https://github.com/ircv3/ircv3-specifications/pull/417), a new draft extension simplifying bridging with other chat systems (thanks [@jlu5](https://github.com/jlu5)!)
* New moderation tools: `+u` ("auditorium", #1300), `+U` ("op-moderated", #1178), `+M` ("moderated-registered", #1182, thanks [@ajaspers](https://github.com/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.
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
* 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](https://github.com/csmith)!)
* Added `server.ip-check-script` for configuring IP check plugins (#68, #1267, thanks [@moortens](https://github.com/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](https://github.com/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](https://github.com/ajaspers)!)
* Disallowed the use of service nicknames during roleplaying (#1240, thanks [@Mitaka8](https://github.com/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](https://github.com/jesopo)!)
* It was not possible to set or unset the `+T` no-CTCP user mode; this has been fixed (#1299, thanks [@mogad0n](https://github.com/mogad0n)!)
* Fixed edge cases with `/NICKSERV SAREGISTER` of confusable nicknames (#1322, thanks [@mogad0n](https://github.com/mogad0n)!)
* Fixed websocket listeners with proxy-before-TLS enabled closing on invalid PROXY lines (#1269, thanks [@RyanSquared](https://github.com/RyanSquared)!)
* Fixed error responses and history for SANICK (#1277, #1278, thanks [@eskimo](https://github.com/eskimo)!)
* Ensured that stored realnames of always-on clients are deleted during account unregistration (#1330)
* Whitespace is now stripped from KLINEs (#1327, thanks [@mogad0n](https://github.com/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](https://github.com/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](https://github.com/ircv3/ircv3-specifications/pull/417) extension, which simplifies bridging IRC with other protocols relaymsg (#1119, thanks [@jlu5](https://github.com/jlu5)!)
* Added `ip-check-script`, a scripting API for restricting access by client IP. We provide [oragono-dnsbl](https://github.com/oragono/oragono-dnsbl), an external script that can query DNSBLs for this purpose (#68, #1267, thanks [@moortens](https://github.com/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](https://gist.github.com/edk0/bf3b50fc219fd1bed1aa15d98bfb6495) extension, which exposes a cleaner account registration API to clients (#1075, thanks [@edk0](https://github.com/edk0)!)
* Added a `379 RPL_WHOISMODES` line to the `WHOIS` response, making it easier for operators to see other users' modes (#769, thanks [@Amiga60077](https://github.com/Amiga60077) and [@KoraggKnightWolf](https://github.com/KoraggKnightWolf)!)
* Added `r` flag to `/WHO` responses for registered nicknames (#1366, thanks [@Amiga60077](https://github.com/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](https://github.com/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](https://github.com/ajaspers)!)
* Improved `SETNAME` behavior for legacy clients (#1358, thanks [@KoraggKnightWolf](https://github.com/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)
This release contains primarily bug fixes, but includes one notable feature enhancement: a change contributed by [@hhirtz](https://github.com/hhirtz) that updates the `draft/rename` specification to correspond to the new (soon-to-be) published draft.

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.
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).
### 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](https://github.com/oragono/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](https://github.com/RyanSquared)!)
* 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](https://github.com/k4bek4be)!)
* Added `extjwt` section for configuring the EXTJWT extension (#948, #1136)
*`login-via-pass-command: true` is now a recommended default (#1186)
* Added support for [WHOX](https://github.com/ircv3/ircv3-specifications/issues/81), contributed by [@jesopo](https://github.com/jesopo) (#938, thanks!)
* Added support for tracking missed messages across multiple devices; see the "history" section of the manual for details (#843, thanks [@jwheare](https://github.com/jwheare) and [@wrmsr](https://github.com/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](https://github.com/daurnimator)!)
* Added the `/DEFCON` command, allowing operators to respond to spam or DoS attacks by disabling features at runtime without a rehash. (This feature requires that the operator have a newly defined capability, named `defcon`; this can be added to the appropriate oper blocks in the config file.) (#328, thanks [@bogdomania](https://github.com/bogdomania)!)
* Added support for the [EXTJWT](https://github.com/ircv3/ircv3-specifications/pull/341) draft extension, allowing Oragono to be integrated with other systems like Jitsi (#948, #1136)
* Services (NickServ, ChanServ, etc.) now respond to CTCP VERSION messages (#1055, thanks [@jesopo](https://github.com/jesopo)!)
* Added `BOT` ISUPPORT token, plus a `B` flag for bots in `352 RPL_WHOREPLY` (#1117)
* Added support for the `+T` no-CTCP user mode (#1007, thanks [@clukawski](https://github.com/clukawski)!)
* Added support for persisting the realname of always-on clients (#1065, thanks [@clukawski](https://github.com/clukawski)!)
* Added a warning on incorrect arguments to `/NICKSERV REGISTER` (#1179, thanks [@LukeHoersten](https://github.com/LukeHoersten)!)
* Fixed a number of issues affecting the `znc.in/playback` capability, in particular restoring compatibility with Palaver (#1205, thanks [@kylef](https://github.com/kylef)!)
* Fixed interaction of auto-away with the regular `/AWAY` command (#1207)
* Fixed a race condition where nicknames of signed-out users could remain in the channel names list (#1166, thanks [@eskimo](https://github.com/eskimo)!)
* Fixed the last line of the MOTD being truncated in the absence of a terminating `\n` (#1167, thanks [@eskimo](https://github.com/eskimo)!)
* Fixed incorrect source of some nickserv messages (#1185)
* Fixed idle time being updated on non-PRIVMSG commands (thanks r3m and [@happyhater](https://github.com/happyhater)!)
* Fixed `/NICKSERV UNREGISTER` and `/NICKSERV ERASE` not deleting stored user modes (#1157)
### Security
* Connections to an STS-only listener no longer reveal the exact server version or server creation time (#802, thanks [@csmith](https://github.com/csmith)!)
### Changed
*`/DLINE` now operates on individual client connections (#1135)
* When using the multiclient feature, each client now has its own independent `MONITOR` list (#1053, thanks [@ajaspers](https://github.com/ajaspers)!)
*`MONITOR L` now lists the nicknames in the form they were originally sent with `MONITOR +`, without casefolding (#1083)
* We now send the traditional `445 ERR_SUMMONDISABLED` and `446 ERR_USERSDISABLED` in response to the `SUMMON` and `USERS` commands (#1078, thanks [@KoraggKnightWolf](https://github.com/KoraggKnightWolf)!)
* RPL_ISUPPORT parameters with no values are now sent without an `=` (#1067, #1069, #1091, thanks [@KoraggKnightWolf](https://github.com/KoraggKnightWolf) and [@jesopo](https;//github.com/jesopo)!)
* TAGMSG storage is now controlled via the `history.tagmsg-storage` config block (#1172)
*`/NICKSERV CERT ADD` with no argument now adds the user's current TLS certificate fingerprint, when applicable (#1059, thanks [@emersonveenstra](https://github.com/emersonveenstra)!)
### Internal
* The config file containing recommended defaults is now named `default.yaml`, instead of `oragono.yaml` (#1130, thanks [@k4bek4be](https://github.com/k4bek4be)!)
* The output of the `/INFO` command now includes the full git hash, when applicable (#1105)
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](https://github.com/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

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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/prawnsalad)!)
* Fixed invisible users not being hidden from `WHO *` queries (#991, thanks [@ajaspers](https://github.com/ajaspers)!)
* Restricted nicknames of some additional common services: `OperServ`, `BotServ`, `MemoServ`, and `Global` (#1080, thanks [@KoraggKnightWolf](https://github.com/KoraggKnightWolf)!)
* Fixed roleplay commands, which were completely broken from v1.1.0 through v2.0.0 (#865, thanks [@petteri](https://github.com/petteri) and [@Mitaka8](https://github.com/Mitaka8)!)
* Fixed `/SAMODE` applying user mode changes to the operator instead of the target user (#866, thanks [@csmith](https://github.com/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](https://github.com/PizzaLover2007)!)
* Fixed `TAGMSG` not being replayed correctly in history (#1044)
* Fixed registration completing after `NICK` and an ident response, without waiting for `USER` (#1057, thanks [@KoraggKnightWolf](https://github.com/KoraggKnightWolf)!)
* Fixed messages rejected by the `+R` mode being stored in history (#1061, thanks [@KoraggKnightWolf](https://github.com/KoraggKnightWolf)!)
* 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](https://github.com/bogdomania) and [@xPaw](https://github.com/xPaw)!)
* Increased the TLS handshake timeout, increasing reliability under high CPU contention (#894)
* Fixed incorrect parameter limit for `MONITOR` in the `TARGMAX` isupport token (#1090, thanks [@KoraggKnightWolf](https://github.com/KoraggKnightWolf)!)
* Fixed edge cases in handling of the `+k` channel mode parameter (#874, thanks [@hhirtz](https://github.com/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](https://github.com/PizzaLover2007)!)
* Fixed `255 RPL_LUSERME` response to indicate that the number of federated peer servers is 0 (#846, thanks [@RyanSquared](https://github.com/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](https://github.com/bogdomania)!)
* Updated the [setname](https://ircv3.net/specs/extensions/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](https://github.com/PizzaLover2007), [@jesopo](https://github.com/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
* Added native support for websockets (#967, thanks [@hhirtz](https://github.com/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](https://github.com/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](https://github.com/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](https://freenode.net/kb/answer/registration#logging-in) syntax used by Freenode. To enable this feature, set `accounts.login-via-pass-command` to `true`. (#1020, thanks [@jlnt](https://github.com/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](https://github.com/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)
* Official releases are now built with `-trimpath` (#901)

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).

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:
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).
* Made the connection limiter and throttler more resilient against the failure to whitelist a reverse proxy IP (#197, thanks [@prawnsalad](https://github.com/prawnsalad)!)
Oragono 1.1.1 is a bugfix release for flaws in message handling, including one with security implications.
Many thanks to [@streaps](https://github.com/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](https://github.com/streaps)!)
* 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](https://ircv3.net/specs/extensions/message-tags.html) and [message ID](https://ircv3.net/specs/extensions/message-ids.html) 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.

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.
*`limits.linelen.tags` removed due to ratification of the [message-tags spec](https://ircv3.net/specs/extensions/message-tags.html), 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).

* Secret channels (mode `+s`) now act more secret (#380, thanks [@csmith](https://github.com/csmith)!).
* The `+R` (registered-only) mode now prevents unregistered users from joining the channel, not just from speaking (#463, thanks [@bogdomania](https://github.com/bogdomania)!).

* Notices from NickServ/ChanServ/etc should display better in some clients (#496, thanks [@jwheare](https://github.com/jwheare)!).
* Fixed nickname timer warnings not displaying correctly sometimes (#449, thanks [@bogdomania](https://github.com/bogdomania)!).
* When history playback is disabled, the `/HISTORY` command now says so instead of silently failing (#429, thanks [@bogdomania](https://github.com/bogdomania)!).
* The `/HOSTSERV ON/OFF` commands now tell you when you don't have a vhost (#404, thanks [@bogdomania](https://github.com/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](https://github.com/bogdomania)!).
* History playback now includes messages that the user sent themselves (especially useful with the new bouncer-like capabilities) (#487).
* 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).
* Oragono can now be used as a Tor hidden service (see the manual for details) (#369).
* The `znc.in/playback` capability is now supported, which can automate history playback for clients that support it (#486).
* User preference system controlling various behaviors (`/msg NickServ help set` for details) (#466).
* Support for the [draft/event-playback](https://github.com/DanielOaks/ircv3-specifications/blob/master+event-playback/extensions/batch/history.md) spec (#457).

* Added the draft IRCv3 [`SETNAME` command](https://ircv3.net/specs/extensions/setname) for changing your realname (#372).
* Registering an account with NickServ is now `/msg NickServ register <password>`, which registers the current nickname as an account, matching other services (#410).
* Added a compatibility hack to make SASL work with ZNC 1.6.x (#261).
* We now support the ratified [message-tags](https://ircv3.net/specs/extensions/message-tags.html) spec, replacing `draft/message-tags-0.2`.

* We now support [`draft/resume-0.5`](https://github.com/ircv3/ircv3-specifications/pull/306) and the associated `BRB` command, replacing `draft/resume-0.3`.
* Upgraded support for the `/RENAME` command to the [latest draft of the specification](https://github.com/ircv3/ircv3-specifications/pull/308).
* Upgraded support for the `/ACC` command to the [latest draft of the specification](https://github.com/DanielOaks/ircv3-specifications/blob/register-and-verify/extensions/acc-core.md) (#453, #455).
* Removed the `+a` away mode as no other servers use it (#468, thanks [@jesopo](https://github.com/jesopo) and [@jwheare](https://github.com/jwheare)!).
* Forcing trailing parameters for legacy compatibility can now be disabled in config (#479).
*`autoreplay-on-join` no longer replays `JOIN` and `PART` lines by default (#474, thanks [@amyspark](https://github.com/amyspark)!).
* snomasks are no longer sent for unregistered clients (#362, thanks [@bogdomania](https://github.com/bogdomania)!).

*`ISON` now reports services (ChanServ/NickServ/etc) as online (#488).
* All times are now reported in UTC (#480).
*`NICKSERV ENFORCE` is deprecated in favor of the new `NICKSERV SET ENFORCE` (the old syntax is still available as an alias).
* The `WHO` command is now treated like `PONG` in that it doesn't count as user activity, since client software often uses it automatically (#485).
* The `NAMES` command now only returns results for the first given channel (#534).
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](https://github.com/csmith) our [Docker builds](https://hub.docker.com/r/oragono/oragono/) have been updated, with automatic rebuilds as we develop the software. Thanks to [@bogdomania](https://github.com/bogdomania) our translation workflow has been improved a lot.
* Optional support for storing and replaying message history with the [`draft/resume-0.3` capability](https://github.com/ircv3/ircv3-specifications/pull/306), the draft IRCv3 `CHATHISTORY` command, and a custom `HISTORY` command.
Thanks to Mauropek, [@modinfo](https://github.com/modinfo), [@bogdomania](https://github.com/bogdomania), [@Shillos](https://github.com/Shillos), Tony Chen, and Remini for adding new translations. Thanks to [@Ascrod](https://github.com/Ascrod), [@bogdomania](https://github.com/bogdomania), [@csmith](https://github.com/csmith), [@jesopo](https://github.com/jesopo), [@jwheare](https://github.com/jwheare), [@remini1998](https://github.com/remini1998), [@enckse](https://github.com/enckse), and [@iNecas](https://github.com/iNecas) for finding bugs and/or writing new features.
*`INVITE`: Fixed bug where invited users could not join the channel they were invited to (thanks to [@unendingpattern](https://github.com/unendingpattern)!).
*`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.
* Fixed many responses that violated the specifications (thanks to [@Ascrod](https://github.com/Ascrod), [@bogdomania](https://github.com/bogdomania), [@csmith](https://github.com/csmith), [@jesopo](https://github.com/jesopo), and [@jwheare](https://github.com/jwheare)!).
* Prevented the db handler from automagically creating the database without initializing it (thanks [@enckse](https://github.com/enckse)!). We also now automatically create the datastore on `run`.
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](https://github.com/edmund-huber/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](https://github.com/slingamn) for a lot of heavy lifting this release and to [vilmibm](https://github.com/vilmibm) for contributing a documentation fix!
* Fixed `LUSERS` to make it display correct client count and output correct params (thanks [@moortens](https://github.com/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.
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](https://crowdin.com/project/oragono) 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 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!).
* 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](https://github.com/prawnsalad) for bringing up this issue).
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!
There has been a bunch of new changes in this release! From [`sts`](http://ircv3.net/specs/extensions/sts.html) being ratified to supporting [`WEBIRC`](ircv3.net/specs/extensions/webirc.html) 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 `+mR`channel 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.
* 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](http://ircv3.net/specs/extensions/message-ids.html).
* Removed websocket support (conflicted with existing larger IRCd's implementations and not used by any real clients).
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.
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.
* 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.
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!
With this release, we're moving to a proper [Github organisation](https://github.com/oragono), 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.
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.
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.
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.
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`.
* Connection limits can now be freely enabled or disabled. If updating, check the new `enabled` flag under the `connection-limits` section of the config.
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.
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.
