     GtkApplication. The main process of `gimp-console` on the other hand is a
     `GimpConsoleApp` which is derived from GApplication. Both new classes share
     a same GimpCoreApp interface. This is a main step for the GTK+3 port.
+  - Various improvements on awareness of multi-item selection across core
+    features. A notable fix is the preview when transforming multiple layers at
+    once (with various transform tools). Various actions are now multi-drawable
+    aware as well.
+  - New "Vectors Structure" in the XCF format: XCF files (format bumped to
+    version 18) can now store and load all the usual and common properties of
+    other items. In other words, it makes XCF now able to store locks, color
+    tags and several selected paths.
+  - XCF saving with RLE and zlib encoding are now multi-threaded and therefore
+    much faster in most cases.

+  - Align tool:
+    * now multi-item aware, it is much more usable than it used to be when we
+      had to click on canvas to select items.
+    * On-canvas clicks are now only needed to select guides (Alt or Alt-Shift
+      click and selected guide colors change) or for the reference object
+      (normal click).
+    * Also the reference object gets on-canvas handles and the name is written
+      in the dockable, making it obvious if you selected the right reference or
+      not.
+    * Moreover the selected reference will now loop when layers are stacked on
+      each other, which allow to select a bottom layer, even if there are layers
+      above it everywhere.
+    * New option "Use extents of layer contents" to Align tool: this is similar
+      to first run "Crop to Content" on every layer to align or distribute
+      (without actually cropping the layers).
