+
+# v1.12.0
+
+## Breaking changes
+The slack bridge has been split in a `slack-legacy` and `slack` bridge.
+If you're still using `legacy tokens` and want to keep using them you'll have to rename `slack` to `slack-legacy` in your configuration. See [wiki](https://github.com/42wim/matterbridge/wiki/Section-Slack-(basic)#legacy-configuration) for more information.
+
+To migrate to the new bot-token based setup you can follow the instructions [here](https://github.com/42wim/matterbridge/wiki/Slack-bot-setup).
+
+Slack legacy tokens may be deprecated by Slack at short notice, so it is STRONGLY recommended to use a proper bot-token instead.
+
+## New features
+* general: New {GATEWAY} variable for `RemoteNickFormat` #501. See `RemoteNickFormat` in matterbridge.toml.sample.
+* general: New {CHANNEL} variable for `RemoteNickFormat` #515. See `RemoteNickFormat` in matterbridge.toml.sample.
+* general: Remove hyphens when auto-loading envvars from viper config #545
+* discord: You can mention discord-users from other bridges.
+* slack: Preserve threading between Slack instances #529. See `PreserveThreading` in matterbridge.toml.sample.
+* slack: Add ability to show when user is typing across Slack bridges #559
+* slack: Add rate-limiting
+* mattermost: Add support for mattermost [matterbridge plugin](https://github.com/matterbridge/mattermost-plugin)
+* api: Respond with message on connect. #550
+* api: Add a health endpoint to API #554
+
+## Bugfix
+* slack: Refactoring and making it better.
+* slack: Restore file comments coming from Slack. #583
+* irc: Fix IRC line splitting. #587
+* mattermost: Fix cookie and personal token behaviour. #530
+* mattermost: Check for expiring sessions and reconnect.
+
+

-## TOML parser and encoder for Go with reflection
-
-TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
-reflection interface similar to Go's standard library `json` and `xml`
-packages. This package also supports the `encoding.TextUnmarshaler` and
-`encoding.TextMarshaler` interfaces so that you can define custom data
-representations. (There is an example of this below.)
-
-Spec: https://github.com/toml-lang/toml
-
-Compatible with TOML version
-[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
-
-Documentation: https://godoc.org/github.com/BurntSushi/toml
-
-Installation:
-
-```bash
-go get github.com/BurntSushi/toml
-```
-
-Try the toml validator:
-
-```bash
-go get github.com/BurntSushi/toml/cmd/tomlv
-tomlv some-toml-file.toml
-```
-
-[![Build Status](https://travis-ci.org/BurntSushi/toml.svg?branch=master)](https://travis-ci.org/BurntSushi/toml) [![GoDoc](https://godoc.org/github.com/BurntSushi/toml?status.svg)](https://godoc.org/github.com/BurntSushi/toml)
-
-### Testing
-
-This package passes all tests in
-[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
-and the encoder.
-
-### Examples
-
-This package works similarly to how the Go standard library handles `XML`
-and `JSON`. Namely, data is loaded into Go values via reflection.
-
-For the simplest example, consider some TOML file as just a list of keys
-and values:
-
-```toml
-Age = 25
-Cats = [ "Cauchy", "Plato" ]
-Pi = 3.14
-Perfection = [ 6, 28, 496, 8128 ]
-DOB = 1987-07-05T05:45:00Z
-```
-
-Which could be defined in Go as:
-
-```go
-type Config struct {
-  Age int
-  Cats []string
-  Pi float64
-  Perfection []int
-  DOB time.Time // requires `import time`
-}
-```
-
-And then decoded with:
-
-```go
-var conf Config
-if _, err := toml.Decode(tomlData, &conf); err != nil {
-  // handle error
-}
-```
-
-You can also use struct tags if your struct field name doesn't map to a TOML
-key value directly:
-
-```toml
-some_key_NAME = "wat"
-```
-
-```go
-type TOML struct {
-  ObscureKey string `toml:"some_key_NAME"`
-}
-```
-
-### Using the `encoding.TextUnmarshaler` interface
-
-Here's an example that automatically parses duration strings into
-`time.Duration` values:
-
-```toml
-[[song]]
-name = "Thunder Road"
-duration = "4m49s"
-
-[[song]]
-name = "Stairway to Heaven"
-duration = "8m03s"
-```
-
-Which can be decoded with:
-
-```go
-type song struct {
-  Name     string
-  Duration duration
-}
-type songs struct {
-  Song []song
-}
-var favorites songs
-if _, err := toml.Decode(blob, &favorites); err != nil {
-  log.Fatal(err)
-}
-
-for _, s := range favorites.Song {
-  fmt.Printf("%s (%s)\n", s.Name, s.Duration)
-}
-```
-
-And you'll also need a `duration` type that satisfies the
-`encoding.TextUnmarshaler` interface:
-
-```go
-type duration struct {
-	time.Duration
-}
-
-func (d *duration) UnmarshalText(text []byte) error {
-	var err error
-	d.Duration, err = time.ParseDuration(string(text))
-	return err
-}
-```
-
-### More complex usage
-
-Here's an example of how to load the example from the official spec page:
-
-```toml
-# This is a TOML document. Boom.
-
-title = "TOML Example"
-
-[owner]
-name = "Tom Preston-Werner"
-organization = "GitHub"
-bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
-dob = 1979-05-27T07:32:00Z # First class dates? Why not?
-
-[database]
-server = "192.168.1.1"
-ports = [ 8001, 8001, 8002 ]
-connection_max = 5000
-enabled = true
-
-[servers]
-
-  # You can indent as you please. Tabs or spaces. TOML don't care.
-  [servers.alpha]
-  ip = "10.0.0.1"
-  dc = "eqdc10"
-
-  [servers.beta]
-  ip = "10.0.0.2"
-  dc = "eqdc10"
-
-[clients]
-data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
-
-# Line breaks are OK when inside arrays
-hosts = [
-  "alpha",
-  "omega"
-]
-```
-
-And the corresponding Go types are:
-
-```go
-type tomlConfig struct {
-	Title string
-	Owner ownerInfo
-	DB database `toml:"database"`
-	Servers map[string]server
-	Clients clients
-}
-
-type ownerInfo struct {
-	Name string
-	Org string `toml:"organization"`
-	Bio string
-	DOB time.Time
-}
-
-type database struct {
-	Server string
-	Ports []int
-	ConnMax int `toml:"connection_max"`
-	Enabled bool
-}
-
-type server struct {
-	IP string
-	DC string
-}
-
-type clients struct {
-	Data [][]interface{}
-	Hosts []string
-}
-```
-
-Note that a case insensitive match will be tried if an exact match can't be
-found.
-
-A working example of the above can be found in `_examples/example.{go,toml}`.

-Package toml provides facilities for decoding and encoding TOML configuration

-MetaData type.
-
-The specification implemented: https://github.com/toml-lang/toml
-
-The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
-whether a file is a valid TOML document. It can also be used to print the
-type of each key in a TOML document.
-
-Testing
-
-There are two important types of tests used for this package. The first is
-contained inside '*_test.go' files and uses the standard Go unit testing
-framework. These tests are primarily devoted to holistically testing the
-decoder and encoder.
-
-The second type of testing is used to verify the implementation's adherence
-to the TOML specification. These tests have been factored into their own
-project: https://github.com/BurntSushi/toml-test
-
-The reason the tests are in a separate project is so that they can be used by
-any implementation of TOML. Namely, it is language agnostic.
