 # Release Notes
 
+## 2.52
+
+Posts that were liked or boosted can now be unliked and unboosted.
+
+Added a header to avoid over-zealous caching in some browsers (contributed by louis77).
+
+## 2.51
+
+Support for custom Emojis has been added; they are no longer hardcoded, but read from the `emojis.json` file at the server base directory. Also, they are no longer limited to string substitutions, but images as external URLs are also supported (see `snac(8)` for more information).
+
+Fixed a bug that caused some notifications to be lost when coming from a user in the same instance.
+
+Added an additional check for blocked instances (sometimes, posts from blocked sites that were ancestors of legit posts were 'leaking' into the timeline).
+
+On OpenBSD, if the `disable_email_notifications` server flag is set to `true`, `unveil()` is not called for the execution of the `/usr/sbin/sendmail` binary and `pledge()` doesn't set the `exec` promise.
+
+## 2.50
+
+Incoming posts can now be filtered out by content using regular expressions on a server level (these regexes are written in the `filter_reject.txt` file at the server base directory; see `snac(5)` and `snac(8)`).
+
+Improved page position after hitting the `Hide` or `MUTE` buttons (for most cases).
+
+Use a shorter maximum conversation thread level (also, this maximum value is now configurable at compilation level with the `MAX_CONVERSATION_LEVELS` define).
+
+Fixed a bug where editing a post made the attached media or video to be lost.
+
+The way of refreshing remote actor data has been improved.
+
+Posting from the command-line now allows attachments.
+
+Added defines for time to enable MacOS builds (contributed by andypiper).
+
 ## 2.49
 
 Mastodon API: Fixed a bug in how validated links are reported.
