+Version 1.53.4
+--------------
+
+- Refactored the way GObject properties are accessed. This should be a bit more
+  efficient, as property info (GParamSpec) is now cached for every object type.
+  There may still be some regressions from this; please be on the lookout so
+  we can fix them in the next release.
+
+- The memory usage for each object instance has been reduced, resulting in
+  several dozens of megabytes less memory usage in GNOME Shell.
+
+- The CI pipeline was refactored, now runs a lot faster, detects more failure
+  situations, builds on different architectures, uses the GitLab Docker
+  registry, and publishes code coverage statistics to
+  https://gnome.pages.gitlab.gnome.org/gjs/
+
+- For contributors, the C++ style guide has been updated, and there is now a
+  script in the tools/ directory that will install a Git hook to automatically
+  format your code when you commit it. The configuration may not be perfect yet,
+  so bear with us while we get it right.
