+Overview of Changes from GIMP 2.10.24 to GIMP 2.10.26
+=====================================================
+
+Plug-ins:
+
+  - Improved DDS support and fix some red/blue bit swap for RGB10A2 DDS.
+    The plug-in version is incremented so that it is able to catch and
+    correct previously incorrect RGB10A2 images exported by older
+    versions of our plug-in.
+
+Script-fu:
+
+  - New (dir-make "/dir/name" mode) function to create a directory.
+
+Build:
+
+  - On Windows, *.rs file extension is not associated with SUN Raster
+    images anymore. The reason is that this file extension is mostly
+    used for Rust code files nowadays. If Windows could detect file
+    formats with "magic numbers" (i.e. byte identifiers), it would not
+    be a problem, but since it relies apparently only the extension,
+    it's better to remove this association.
+  - Oppositely on Linux and other Unix-like systems using desktop files,
+    add the image/x-sun-raster MimeType which was forgotten (there,
+    detection should be fine and not depend on file extension).
