+* TileSheetEditor: Fix overrun errors when switching subsheets, clear selection
+  on switch (261e324acd)
+* Fix new build error that occurs in MSVC (26d5048e6720c4c2d52508a6ee44c67dd9fe3ee5)
+
+# d2025.05.0
 
 * Add app icon for both window and file
-* Fix selection clearing in TileSheet editor to work when clicking outside
+* Change application font to Roboto Medium
+* Closing application will now confirm with user if any files have unsaved
+  changes.
+* UUID duplicates will now be reported when opening a project
+* Deleting a directory now closes files in that directory
+* Delete key now initiates deletion of selected directory
+* Remove ability to re-order tabs. There were bugs associated with that.
+* TileSheetEditor: Fix selection clearing in to work when clicking outside
   image.
-* Fix color number key range in PalettEditor. Previously, pressing A caused the
-  editor to jump to the last color.
+* TileSheetEditor: Fix Delete Tile functionality, which was completely broken
+* PaletteEditor: Fix color number key range in. Previously, pressing A caused
+  the editor to jump to the last color.
+* PaletteEditor: page rename will now take effect upon pressing enter if the
