 # Changelog
 
-## Squawk 0.2.0 (Unreleased)
+## Squawk 0.2.0 (Jan 10, 2022)
 ### Bug fixes
 - carbon copies switches on again after reconnection
 - requesting the history of the current chat after reconnection
 - global availability (in drop down list) gets restored after reconnection
 - status icon in active chat changes when presence of the pen pal changes
 - infinite progress when open the dialogue with something that has no history to show
+- fallback icons for buttons, when no supported theme is installed (shunf4)
+- better handling messages with no id (shunf4)
+- removed dependency: uuid, now it's on Qt (shunf4)
+- better requesting latest history (shunf4)
 
 ### Improvements
 - slightly reduced the traffic on the startup by not requesting history of all MUCs
-- completely rewritten message feed, now it works way faster
+- completely rewritten message feed, now it works way faster and looks cooler
 - OPTIONAL RUNTIME dependency: "KIO Widgets" that is supposed to allow you to open a file in your default file manager
 - show in folder now is supposed to try it's best to show file in folder, even you don't have KIO installed
 - once uploaded local files don't get second time uploaded - the remote URL is reused
+- way better compilation time (vae)
+
+### New features
+- pasting images from clipboard to attachment (shunf4)
+- possible compilation for windows and macOS (shunf4)
