+ReleaseNotes: |-
+  IMPORTANT:
+  This is the first beta 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.
+  Note: When it comes to features, this release should be quite similar to the stable 3.1.0 releaseChanges
+  - Packages will be loaded and stored by a Package Loader, instead of being loaded by the interface.
+  - Package lists have been rebuilt to use ItemsView, causing UniGetUI to use less ram (~290mb max -> ~210mb max)
+  - The Widgets API has been optimized. Packages load up to way faster on the widgets.
+  - The Package Manager logs have been rebuilt from the grounds up.
+      - Package Manager logs for each manager can be isolated
+      - Normal and Verbose views available
+  - Improvements to keyboard navigation
+  - Chocolatey can be set to not be installed by the UniGetUI Installer
+  - Lots of internal code changes and optimizations.
+  - Other bugfixes
