   - Some cleanup of outdated disabled unit tests and other warnings.
   - Restructuration of internal GimpControllerManager and
     GimpContainerView API.
+  - GimpContainerListView now uses a GtkListBox. A Playground switch was
+    added to use the new widgets in all views that can be switched
+    between list and grid view (brushes, patterns etc.). This won't
+    likely get out of Playground before GIMP 4 because it is far too
+    slow right now (and apparently we'll need GTK4 for making it fast as
+    our current lists).
   - Various code have been moving away from GtkTreeView and some new
     internal classes were added as a preparation for GTK4 port.
+  - GEX format updated to use standard <custom/> instead of <metadata/>
+    per update in the AppStream specs in the last few years. This
+    doesn't make any compatibility issue since this format is purely
+    internal only for now, not public.
+  - New setting "Update metadata automatically" in Preferences > Image
+    Import & Export > Export Policies. When enabled, add and update
+    metadata automatically. When disabled, only the minimum necessary
+    metadata changes are made, without changing modification date,
+    synchronizing tags, or updating the software and change history
+    metadata. This new setting is enabled by default.
+  - Fix palette import to properly import colors with alpha values from
+    palettes.

+  - GimpSizeEntry (libgimpwidget) can now parse mathematical expressions
+    in their reference value spin buttons too.
+  - GimpColorScales (libgimpwidget) will now set its decimals to 0 when
+    creating u8 RGB color selectors. This change will help further
+    distinguish between the 0...00 and 0..255 views in the Color
+    Selectors. It will also better convey to users that u8 is an integer

+  - Favor existing image comment instead of always loading comment from

+    GimpMetadataSaveFlags (libgimpbase).
 
 Build:
 
   - Add nightly Snap package.
   - Add nightly Aarch64 flatpak.
+  - appstream-glib dependency replaced with libappstream
