# Changelog All notable changes to Oragono will be documented in this file. This project adheres to [Semantic Versioning](http://semver.org/). For the purposes of versioning, we consider the "public API" to refer to the configuration files, CLI interface and database format. ## Unreleased New release of Oragono! ### Security ### 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. ### 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. ### Removed ### 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 `NICK`s, to be more safe. * Send channel `NOTICE`s 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`](http://ircv3.net/specs/extensions/chghost-3.2.html). ### 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`](http://ircv3.net/specs/extensions/cap-notify-3.2.html) and [`echo-message`](http://ircv3.net/specs/extensions/echo-message-3.2.html). ### 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](http://ircv3.net/specs/core/capability-negotiation-3.2.html) including CAP values. * Added support for IRCv3 capabilities [`account-notify`](http://ircv3.net/specs/extensions/account-notify-3.1.html), [`invite-notify`](http://ircv3.net/specs/extensions/invite-notify-3.2.html), [`monitor`](http://ircv3.net/specs/core/monitor-3.2.html), [`sasl`](http://ircv3.net/specs/extensions/sasl-3.2.html), and draft capability [`message-tags`](http://ircv3.net/specs/core/message-tags-3.3.html) as `draft/message-tags`. ### Changed * Casemapping changed from custom unicode mapping to preliminary [rfc7700](https://github.com/ircv3/ircv3-specifications/pull/272) 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](https://tools.ietf.org/html/rfc1413) on client connection. * [`RPL_ISUPPORT`](http://modern.ircdocs.horse/#rplisupport-005) 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`](http://ircv3.net/specs/extensions/account-tag-3.2.html), [`away-notify`](http://ircv3.net/specs/extensions/away-notify-3.1.html), [`extended-join`](http://ircv3.net/specs/extensions/extended-join-3.1.html), [`sasl`](http://ircv3.net/specs/extensions/sasl-3.1.html), [`server-time`](http://ircv3.net/specs/extensions/server-time-3.2.html), and [`userhost-in-names`](http://ircv3.net/specs/extensions/userhost-in-names-3.2.html). ### 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 `` 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 `` param on `RPL_ENDOFWHOIS`. * WHOIS: Hide hidden channels in WHOIS responses.
