+ReleaseNotes: |-
+  IMPORTANT:
+  This is the second 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: This release attempts to fix an unexpected issue with the WinGet package manager interop. Assuming no more issues are found after this release, UniGetUI 3.1.0 stable will be published.Changes
+  - This release adds a built-in dependency manager, that checks and prompts the user to install missing dependencies for UniGetUI (let's say, for example, Microsoft.WinGet.Client or Scoop-Search).
+  - Other minor issues have been fixed on this release.
