+ReleaseNotes: |-
+  IMPORTANT:
+  This is the second development release to implement the UniGetUI rebranding.
+  Instaling this release will automatically migrate settings and other data to new folders (WingetUI -> UniGetUI), so rolling back to older versions of WingetUI may cause settings to be reset.
+  Changes
+  - Improvements to the rebranding
+  - lots of bugfixes and improvements
+  - Improvements to cache handling with GSudo
+  - By popular demand, window position and size will be saved across app restarts
+  - Change how information is rendered on the Package Details tab. Links should be copyable and should not show cut anymore
