Release v1.11.1

Currently numbers are stripped not just after the color control code (\x03) but also after other formatting such as bold (\x02) and italic (\x1D), which is both unnecessary and leads to missing text from irc. This fixes that by only stripping numbers after the color control code.

+        config file (default "matterbridge.toml")
   -debug
         enable debug

-### mattermost
-#### webhooks version
-You'll have to configure the incoming and outgoing webhooks. 
+# FAQ
 
-* incoming webhooks
-Go to "account settings" - integrations - "incoming webhooks".  
-Choose a channel at "Add a new incoming webhook", this will create a webhook URL right below.  
-This URL should be set in the matterbridge.conf in the [mattermost] section (see above)  
+See [FAQ](https://github.com/42wim/matterbridge/wiki/FAQ)
 
-* outgoing webhooks
-Go to "account settings" - integrations - "outgoing webhooks".  
-Choose a channel (the same as the one from incoming webhooks) and fill in the address and port of the server matterbridge will run on.

-#### plus version
-You'll have to create a new dedicated user on your mattermost instance.
-Specify the login and password in [mattermost] section of matterbridge.conf
-
-## FAQ
-Please look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for more information first. 
-### Mattermost doesn't show the IRC nicks
-If you're running the webhooks version, this can be fixed by either:
-* enabling "override usernames". See [mattermost documentation](http://docs.mattermost.com/developer/webhooks-incoming.html#enabling-incoming-webhooks)
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
-
-If you're running the plus version you'll need to:
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
-
-Also look at the ```RemoteNickFormat``` setting.

+## Breaking Changes
+* URL,UseAPI,BindAddress is deprecated. Your config has to be updated.
+  * URL => WebhookURL
+  * BindAddress => WebhookBindAddress
+  * UseAPI => removed 
+  This change allows you to specify a WebhookURL and a token (slack,discord), so that
+  messages will be sent with the webhook, but received via the token (API)
+  If you have not specified WebhookURL and WebhookBindAddress the API (login or token) 
+  will be used automatically. (no need for UseAPI)
+
+## Bugfix since rc1
+* steam: Fix channel id bug in steam (channels are off by 0x18000000000000)
+* telegram: Add UseInsecureURL option for telegram (default false)
+  WARNING! If enabled this will relay GIF/stickers/documents and other attachments as URLs
+  Those URLs will contain your bot-token. This may not be what you want.
+  For now there is no secure way to relay GIF/stickers/documents without seeing your token.

+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.
