+* irc: Fix Nickserv logic (irc) #602
+
+# 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.

+# gitter
+Gitter API in Go
+https://developer.gitter.im
+
+#### Install
+
+`go get github.com/sromku/go-gitter`
+
+- [Initialize](#initialize)
+- [Users](#users)
+- [Rooms](#rooms)
+- [Messages](#messages)
+- [Stream](#stream)
+- [Faye (Experimental)](#faye-experimental)
+- [Debug](#debug)
+- [App Engine](#app-engine)
+
+##### Initialize
+``` Go
+api := gitter.New("YOUR_ACCESS_TOKEN")
+```
+
+##### Users
+
+- Get current user
+
+	``` Go
+	user, err := api.GetUser()
+	```
+
+##### Rooms
+
+- Get all rooms
+	``` Go
+	rooms, err := api.GetRooms()
+	```
+
+- Get room by id
+	``` Go
+	room, err := api.GetRoom("roomID")
+	```
+
+- Get rooms of some user
+	``` Go
+	rooms, err := api.GetRooms("userID")
+	```
+
+- Join room
+	``` Go
+	room, err := api.JoinRoom("roomID", "userID")
+	```
+	
+- Leave room
+	``` Go
+	room, err := api.LeaveRoom("roomID", "userID")
+	```
+
+- Get room id
+	``` Go
+	id, err := api.GetRoomId("room/uri")
+	```
+
+- Search gitter rooms
+	``` Go
+	rooms, err := api.SearchRooms("search/string")
+	```
+##### Messages
+
+- Get messages of room
+	``` Go
+	messages, err := api.GetMessages("roomID", nil)
+	```
+
+- Get one message
+	``` Go
+	message, err := api.GetMessage("roomID", "messageID")
+	```
+
+- Send message
+	``` Go
+	err := api.SendMessage("roomID", "free chat text")
+	```
+
+##### Stream
+
+Create stream to the room and start listening to incoming messages
+
+``` Go
+stream := api.Stream(room.Id)
+go api.Listen(stream)
+
+for {
+    event := <-stream.Event
+    switch ev := event.Data.(type) {
+    case *gitter.MessageReceived:
+        fmt.Println(ev.Message.From.Username + ": " + ev.Message.Text)
+    case *gitter.GitterConnectionClosed:
+        // connection was closed
+    }
+}
+```
+
+Close stream connection
+
+``` Go
+stream.Close()
+```
+
+##### Faye (Experimental)
+
+``` Go
+faye := api.Faye(room.ID)
+go faye.Listen()
+
+for {
+    event := <-faye.Event
+    switch ev := event.Data.(type) {
+    case *gitter.MessageReceived:
+        fmt.Println(ev.Message.From.Username + ": " + ev.Message.Text)
+    case *gitter.GitterConnectionClosed: //this one is never called in Faye
+        // connection was closed
+    }
+}
+```
+
+##### Debug
+
+You can print the internal errors by enabling debug to true
+
+``` Go
+api.SetDebug(true, nil)
+```
+
+You can also define your own `io.Writer` in case you want to persist the logs somewhere.
+For example keeping the errors on file
+
+``` Go
+logFile, err := os.Create("gitter.log")
+api.SetDebug(true, logFile)
+```
+
+##### App Engine
+
+Initialize app engine client and continue as usual
+
+``` Go
+c := appengine.NewContext(r)
+client := urlfetch.Client(c)
+
+api := gitter.New("YOUR_ACCESS_TOKEN")
+api.SetClient(client)
+```

-Package toml provides facilities for decoding and encoding TOML configuration
-files via reflection. There is also support for delaying decoding with
-the Primitive type, and querying the set of keys in a TOML document with the
-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.
