+# Numbat release (v2.13.0)
+
+## Goals
+
+This release features long-awaited improvements to our Rich Text Pad.
+This work was done over a short period, and we're releasing it now so that users can take advantage of the improvements as soon as possible.
+
+## Update notes
+
+* We've fixed a bug related to chat via an update to our messaging server. To install the update, run `npm update`. This server improvement is backwards compatible, so you can update your clientside or serverside dependencies in either order. Restart your server for the changes to take effect.
+* You can run `bower update` in order to take advantage of the latest clientside dependencies. Depending on when you last updated you may benefit from updates to Codemirror or some other clientside libraries.
+
+## Features
+
+* We've refactored a great deal of CryptPad's Remote Procedure Call mechanisms related to chat. This should simplify CryptPad and make potential bugs less likely to occur.
+
+## Bugfixes
+
+* The behaviour of the cursor in our rich text editor has been greatly improved. Your experience when collaboratively editing should be noticeably better.
+* Characters inserted into rich text pads were sometimes dropped due to a race condition between CKEditor and ChainPad, but this asynchronous behaviour has been resolved. As such the editor should be much more reliable.
+* Deleting chat history from the server now removes it from your chat interface and that of remote messengers, where it previously would require a reload of the interface to see the correct chat history.
+* We now correctly set owners of a shared chat channel such that either chat participant in a one-to-one room can delete the history.
+* If you request history with a `lastKnownHash` which is not in the history, the server informs you that it is not there via a direct message. Clients fall back to a classic full retreival of the history. Previously this would fail, and print a message to the server's stdout.
+* Firefox users may have noticed that when they clicked the dropdown menus for styles in the CKEditor toolbar, their scrollbar would jump to the top of the document. Their scroll position is now preserved in cases where it would previously have been disrupted.
