 # Changelog
 This project adheres to [Semantic Versioning](http://semver.org/).

+## [2.9.0] - 2020-10-03
+This release comes with a (relatively large) change to use discord.js v12!
+There were a lot of breaking changes in the upstream library, including removal of support for Node <12, which prompted a 2.9.0-alpha release before this main version.
+Everything seemed to go fine, which is why you're now receiving this latest update!
+
+### Added
+* IRC nick colors are now customizable in the config (thanks to [KWeaver87](https://github.com/reactiflux/discord-irc/pull/561))
+
+### Changed
+* Upgrade discord.js to 12.3.1 (the pre-release came with 12.2.0) - this changes a lot of how the bot works behind the scenes, and prepares us for upcoming Discord API changes - [#555](https://github.com/reactiflux/discord-irc/pull/555), [#564](https://github.com/reactiflux/discord-irc/pull/564)
+* Add support for Node 14 ([#549](https://github.com/reactiflux/discord-irc/pull/549)); drop support for Node 6, 8 and 10 ([#550](https://github.com/reactiflux/discord-irc/pull/550))
+
+### Fixed
+* A bunch of vulnerabilities listed in `npm audit` are now gone - [#544](https://github.com/reactiflux/discord-irc/pull/544), [#548](https://github.com/reactiflux/discord-irc/pull/548), [#551](https://github.com/reactiflux/discord-irc/pull/551), [#552](https://github.com/reactiflux/discord-irc/pull/552), [#553](https://github.com/reactiflux/discord-irc/pull/553), [#562](https://github.com/reactiflux/discord-irc/pull/562)
+* Log messages now typically take up one line again (fixing a relatively long-standing bug, at this point – oops!) - [#554](https://github.com/reactiflux/discord-irc/pull/554)
+* Mentioning the same user more than once in a single message is now fixed (thanks to [Qyriad](https://github.com/reactiflux/discord-irc/pull/541))
+* Our Discord client now uses a retry limit of 3 (rather than 1) on internal server errors (hopefully fixing [#461](https://github.com/reactiflux/discord-irc/issues/461)) - [#565](https://github.com/reactiflux/discord-irc/pull/565)
+
+## [2.8.1] - 2020-03-16
+### Fixed
+* Large avatars failed to display when bridging through webhooks - (thanks to [Miosame](https://github.com/reactiflux/discord-irc/pull/511), follow up in [#530](https://github.com/reactiflux/discord-irc/pull/530))
+* Update acorn to 7.1.1 - [#534](https://github.com/reactiflux/discord-irc/pull/534)
+* Remove code coverage instrumentation from `dist/` files - [#536](https://github.com/reactiflux/discord-irc/pull/536)
+
+## [2.8.0] - 2019-12-14
+### Added
+* `format.webhookAvatarURL`, to customize the unrecognized user webhook avatar (thanks to [Geo1088](https://github.com/reactiflux/discord-irc/pull/419))
+* `parallelPingFix`, disabled by default, to prevent users of both Discord and IRC getting pings whenever their messages are mirrored to IRC (thanks to [qaisjp](https://github.com/reactiflux/discord-irc/pull/243) originally, follow up in [#502](https://github.com/reactiflux/discord-irc/pull/502) and [#520](https://github.com/reactiflux/discord-irc/pull/520))
+* `ignoreUsers.discordIds`, to ignore specific Discord users through the bridge by ID instead of name (thanks to [nsavch](https://github.com/reactiflux/discord-irc/pull/508))
+* A basic Docker image, found at [discordirc/discord-irc](https://hub.docker.com/r/discordirc/discord-irc)! This may not be often updated with the release tags we publish on GitHub, but it should contain a `latest` tag in addition to whichever Git hash is available on main (thanks to [gdude2002](https://github.com/reactiflux/discord-irc/pull/421), follow up in [#498](https://github.com/reactiflux/discord-irc/pull/498))
+
+### Changed
+* Add support for Node 13, drop testing for Node 6 - [#521](https://github.com/reactiflux/discord-irc/pull/521)
+
+### Fixed
+* Upgrade various dependencies: babel, commander, coveralls, discord.js, eslint, mocha, simple-markdown, sinon, sinon-chai - [#488](https://github.com/reactiflux/discord-irc/pull/488), [#503](https://github.com/reactiflux/discord-irc/pull/503), [#522](https://github.com/reactiflux/discord-irc/pull/522), [#523](https://github.com/reactiflux/discord-irc/pull/523), [#524](https://github.com/reactiflux/discord-irc/pull/524/files), [#525](https://github.com/reactiflux/discord-irc/pull/525)
+
+## [2.7.2] - 2019-08-08
+### Fixed
+* Defer to discord permissions for allowing `@everyone` and `@here` in webhook messages - [#497](https://github.com/reactiflux/discord-irc/pull/497)
+* Support Node 10 and 12 - [#499](https://github.com/reactiflux/discord-irc/pull/499)
+* Upgrade dependencies
+* Tests: Fix lint config deprecation - [#500](https://github.com/reactiflux/discord-irc/pull/500)
+* Tests: Ensure all tests are run in dev environment - [#501](https://github.com/reactiflux/discord-irc/pull/501)

+* Match IRC style mentions at the beginning of message (thanks to [rdb](https://github.com/reactiflux/discord-irc/pull/470)).

+## [2.6.0] - 2018-03-22
+### Added
+* Support for posting messages to Discord using webhooks (thanks to
+  [Fiaxhs](https://github.com/reactiflux/discord-irc/pull/230)!).
+
+Webhooks lets you override nicknames and avatars, so messages coming from IRC
+can appear as regular Discord messages:
+
+![discord-webhook](http://i.imgur.com/lNeJIUI.jpg)
+
+To enable webhooks, follow part 1 of [this
+guide](https://support.discord.com/hc/en-us/articles/228383668-Intro-to-Webhooks)
+to create and retrieve a webhook URL for a specific channel, then enable it in
+discord-irc's config as follows:
+
+```json
+  "webhooks": {
+    "#discord-channel": "https://discord.com/api/webhooks/id/token"
+  }
+```
+

+### Added

+
+* Add the ability to ignore IRC/Discord users by nickname - [#322](https://github.com/reactiflux/discord-irc/pull/322)
+

+* Improve IRC → Discord mentions around non-word characters and nickname prefix matches - [#273](https://github.com/reactiflux/discord-irc/pull/273)
+

+
+* Fix a crash when using the bot in a group DM - [#316](https://github.com/reactiflux/discord-irc/pull/316)
+
+* Use a `prepare` script for transpiling instead of `prepublish`, fixing `npm` installation direct from the GitHub repository - [#323](https://github.com/reactiflux/discord-irc/pull/323)
+
+* Update dependencies:
+
+  - discord.js to 11.2.1

+### Fixed
+* Tests: Use globbing instead of `find` so tests work on Windows - [#279](https://github.com/reactiflux/discord-irc/pull/279)
+
+### Changed
+* Update dependency irc-upd to [0.7.0](https://github.com/Throne3d/node-irc/releases/tag/v0.7.0) - [#284](https://github.com/reactiflux/discord-irc/pull/284)
+
+* Tests: Use Discord objects to simplify code - [#272](https://github.com/reactiflux/discord-irc/pull/272)
+
+## [2.4.1] - 2017-07-16
+### Added
+* Falsy command preludes are no longer sent (previously would choose default prelude) - [#260](https://github.com/reactiflux/discord-irc/pull/260)
+
+### Fixed
+* Update link to IRC library in README so it points to the new irc-upd library - [#264](https://github.com/reactiflux/discord-irc/pull/264)
+

+
+## [2.4.0] - 2017-07-01
+This project now uses [irc-upd](https://github.com/Throne3d/node-irc) as a dependency, instead of the old [irc](https://github.com/martynsmith/node-irc) package – this fork should be better maintained and will solve some bugs, detailed below.
+
+### Added
+* Allow commandCharacters to work for messages sent to Discord - [#221](https://github.com/reactiflux/discord-irc/pull/221).
+
+* Send nick changes from IRC to Discord with `ircStatusNotices` - [#235](https://github.com/reactiflux/discord-irc/pull/235), [#241](https://github.com/reactiflux/discord-irc/pull/241).
+
+* Translate custom emoji references from IRC to Discord - [#256](https://github.com/reactiflux/discord-irc/pull/256).
+
+### Fixed
+* Use `ircClient.nick` instead of `nickname` when checking if the `ircStatusNotices` event is for the bot, to prevent a potential crash - [#257](https://github.com/reactiflux/discord-irc/pull/257).
+
+* Use the updated `irc-upd` library instead of `irc`, causing IRC messages to now be split by byte instead of character (fixing [#199](https://github.com/reactiflux/discord-irc/issues/199)) and adding support for certain Unicode characters in nicknames (fixing [#200](https://github.com/reactiflux/discord-irc/issues/200)) - [#258](https://github.com/reactiflux/discord-irc/pull/258).
+
+* Update dependencies:
+
+  - discord.js to 11.1.0
+  - check-env to 1.3.0
+  - chai to ^4.0.2
+  - nyc to ^11.0.3

+

+### Fixed
+* Fix ircStatucNotices when channels are not lowercase -
+[#219](https://github.com/reactiflux/discord-irc/pull/219).

+### Fixed
+* Fix IRC quit messages sending to all channels by tracking users - [#214](https://github.com/reactiflux/discord-irc/pull/214#pullrequestreview-31156291).

-> Connects [Discord](https://discordapp.com/) and IRC channels by sending messages back and forth.
-
-A mostly feature complete port of [slack-irc](https://github.com/ekmartin/slack-irc).
+> Connects [Discord](https://discord.com/) and [IRC](https://www.ietf.org/rfc/rfc1459.txt) channels by sending messages back and forth.

 ## Example
 ![discord-irc](http://i.imgur.com/oI6iCrf.gif)

 ## Installation and usage
-Either by installing through npm:
+**Note**: discord-irc requires Node.js version 12 or newer, as it depends on [discord.js](https://github.com/hydrabolt/discord.js).
+Future versions may require newer Node.js versions, though we should support active releases.
+
+Before you can run discord-irc you need to create a configuration file by
+following the instructions [here](https://github.com/reactiflux/discord-irc#configuration).
+After you've done that you can replace `/path/to/config.json` in the commands
+below with the path to your newly created configuration file - or just `config.json` if it's
+in the same directory as the one you're starting the bot from.
+
+When you've done that you can install and start the bot either through npm:
+
 ```bash
 $ npm install -g discord-irc
 $ discord-irc --config /path/to/config.json

+## Docker
+As an alternative to running discord-irc directly on your machine, we provide a [Docker container image](https://hub.docker.com/r/discordirc/discord-irc).
+After creating a configuration file, you can fetch the image from Docker Hub and run it with the following command:
+
+```bash
+docker run -v /path/to/config:/config/config.json discordirc/discord-irc
+```
+
+If you've checked out the repository already, you can build the Docker image locally and run that instead:
+
+```bash
+docker build -t discord-irc .
+docker run -v /path/to/config:/config/config.json discord-irc
+```
+
+Note that the path to the config file on the host (`/path/to/config`) _must_ be a valid absolute path to a config file.
+Otherwise, you may get the error "illegal operation on a directory".
+
 ## Configuration
-Create a discord user and join the server you want to connect to IRC.
+First you need to create a Discord bot user, which you can do by following the instructions [here](https://github.com/reactiflux/discord-irc/wiki/Creating-a-discord-bot-&-getting-a-token).

-The `ircOptions` object is passed directly to node-irc ([available options](http://node-irc.readthedocs.org/en/latest/API.html#irc.Client)).
+The `ircOptions` object is passed directly to irc-upd ([available options](https://node-irc-upd.readthedocs.io/en/latest/API.html#irc.Client)).
+
+To retrieve a discord channel ID, write `\#channel` on the relevant server – it should produce something of the form `<#1234567890>`, which you can then use in the `channelMapping` config.
+
+### Webhooks
+Webhooks lets you override nicknames and avatars, so messages coming from IRC
+can appear as regular Discord messages:
+
+![discord-webhook](http://i.imgur.com/lNeJIUI.jpg)
+
+To enable webhooks, follow part 1 of [this
+guide](https://support.discord.com/hc/en-us/articles/228383668-Intro-to-Webhooks)
+to create and retrieve a webhook URL for a specific channel, then enable it in
+discord-irc's config as follows:
+
+```json
+  "webhooks": {
+    "#discord-channel": "https://discord.com/api/webhooks/id/token"
+  }
+```
+
+### Encodings
+If you encounter trouble with some characters being corrupted from some clients (particularly umlauted characters, such as `ä` or `ö`), try installing the optional dependencies `iconv` and `node-icu-charset-detector`.
+The bot will produce a warning when started if the IRC library is unable to convert between encodings.
+
+Further information can be found in [the installation section of irc-upd](https://github.com/Throne3d/node-irc#character-set-detection).
