 ## Unreleased
 ### Fixed
+- AdminFE button no longer scrolls page to top when clicked
+- Pinned statuses no longer appear at bottom of user timeline (still appear as part of the timeline when fetched deep enough)
+- Fixed many many bugs related to new mentions, including spacing and alignment issues
+- Links in profile bios now properly open in new tabs
+- Inline images now respect their intended width/height attributes
+- Links with `&` in them work properly now
+- Interaction list popovers now properly emojify names
 - Completely hidden posts still had 1px border
 - Attachments are ALWAYS in same order as user uploaded, no more "videos first"
 - Attachment description is prefilled with backend-provided default when uploading
 - Proper visual feedback that next image is loading when browsing
 
 ### Changed
+- (You)s are optional (opt-in) now, bolding your nickname is also optional (opt-out)
+- User highlight background now also covers the `@`
+- Reverted back to textual `@`, svg version is opt-in.
 - Settings window has been throughly rearranged to make make more sense and make navication settings easier.
 - Uploaded attachments are uniform with displayed attachments
 - Flash is watchable in media-modal (takes up nearly full screen though due to sizing issues)
 - Notifications about likes/repeats/emoji reacts are now minimized so they always take up same amount of space irrelevant to size of post.
 
 ### Added
+- Options to show domains in mentions
+- Option to show user avatars in mention links (opt-in)
+- Option to disable the tooltip for mentions
 - Option to completely hide muted threads
 - Ability to open videos in modal even if you disabled that feature, via an icon button
 - New button on attachment that indicates that attachment has a description and shows a bar filled with description
