 # Changelog
 
-## [Unreleased]
+## [0.7.2] -- 2020-06-12
+
+### Highlights
+
+- Reactions
+  - React to a message with an emoji! 🎉
+  - Reactions are shown below a message in a small bubble with a counter.
+  - By clicking on that, others can add to the reaction count.
+  - It may help you celebrating a new Nheko Release or react with a 👎 to a failed build to express your frustration.
+  - This uses a new emoji picker. The picker will be improved in the near future (better scrolling, sections, favorites, recently used or similar) and then probably replace the current picker.
+- Support for tagging rooms `[tag]`
+  - Assign custom tags to rooms from the context menu in the room list.
+  - This allows filtering rooms via the group list. This puts you in a focus mode showing only the selected tags.
+  - You can assign multiple tags to group rooms however you like.
+- SSO Login
+  - With this you can now login on servers, that only provide SSO.
+  - Just enter any mxid on the server. Nheko will figure out that you need to use SSO and redirect your browser to the login page.
+  - Complete the login in your browser and Nheko should automatically log you in.
+- Presence
+  - Shows online status of the people you are talking to.
+  - You can define a custom status message to tell others what you are currently up to.
+  - The status message appears next to the usernames in the timeline.
+  - Your server needs to have presence enabled for this to work.
 
-### [0.7.0] -- Unreleased
+### Features
+
+- Respect exif rotation of images
+- An italian translation (contributed by Lorenzo Ancora)
+- Optional alerts in your taskbar (contributed by z33ky)
+- Optional bigger emoji only messages in the timeline (contributed by lkito)
+- Optional hover feedback on messages (contributed by lkito)
+- `/roomnick` to change your displayname in a single room.
+- Preliminary support for showing inline images.
+- Warn about unencrypted messages in encrypted rooms.
+
+### Improvements
+
+- perf: Use less CPU to sort the room list.

+- Improve the login and register masks a bit with hints and validation.
+- Descriptions for settings (contributed by lkito)
+- A visual indicator, that nheko is fetching messages and improved scrolling (contributed by Lasath Fernando)
+
+### Bugfixes
+
+- Fix not being able to join rooms
+- Fix scale factor setting
+- Buildfixes against gcc10 and Qt5.15 (missing includes)
+- Settings now apply immediately again after changing them (only exception should be the scale factor)
+- Join messages should never have empty texts now
+- Timeline should now fail to render less often on platforms with native sibling windows.
+- Don't rescale images on every frame on highdpi screens.
+
+### Upgrade Notes
+
+<span style="color: red;">This updates includes some changes to the database. Older versions don't handle that gracefully and will delete your database. It is therefore recommended to not downgrade below this version!</span>
