 ## Changes
+### 0.6.3
+Some pretty big changes behind the scenes, but they should be fully backwards compatible. Below is a list of changes:
+* `Cheer.getImageURL(...)` should now return a proper URL. Fix #30
+* You can now set a custom PING interval, for how often the connection should ping Twitch. 
+See `TwirkBuilder.setPingInterval` Fix #29
+* You can now assign custom log methods to Twirk, in case you use some kind of logging framework. You can also set 
+different log levels, which gives a bit more control of what to log. 
+See `TwirkBuilder.setLogLevel` and`TwirkBuilder.setXXXLogMethod`. Fix #28 (thanks to PR #31).
+* Calling connect after a disconnect should now work. Fix #26
+* You don't need to include the '#' anymore in the channel name. Fix #21
+
 ### 0.6.2
 Hotfix release since some emote IDs were still not parsed correctly (see #22). This hotfix should hopefully fix this issue.
 Please report any further issues with parsing emotes.

 * Fixed SockerClosedException stacktrace printing on some locales
   * I think I fixed it at least, but this one is hard to test since there are so many locales.
 * Updated the emotes parse for a safer and faster implementation.
-  * This deprecates a previously public method (`EmoteParse.parseEmote(String, String)`), and the new method is package private. There isn't really any need to call these methods from outside the library

 * Twirk will not only show the "User X was not online" or "User X was already online", when in verbose mode.

 #### Extendable
-You can make Twirk use your own implementation of all event types by using custom builder classes. By extending the types Builder interface, and then passing an instance of your custom builder to the TwirkBuilder, you can use your own custom implementation of whichever type you want.

 ```Java
   final Twirk twirk = new TwirkBuilder(channel, SETTINGS.MY_NICK, SETTINGS.MY_PASS)
     .setClearChatBuilder( new MyClearChatBuilder() )
     .build();
 ```
 This will make the Twirk instance build instances of your custom implementation of `ClearChat` events
 
+# Known / Verified bot
+If your bot requires a very high message rate limit, you can request a verified bot account. It will increase the 
+bots message rate limits: https://dev.twitch.tv/docs/irc/guide#known-and-verified-bots
+This isn't strictly necessary if you are just making a bot for your own account, as you might not reach the message 
+limits. For larger/more frequently used bots, it might
+be necessary.
