+Version 1.52.1
+--------------
+
+- This version has more changes than would normally be expected from a stable
+  version. The intention of 1.52.1 is to deliver a version that runs cleaner
+  under performance tools, in time for the upcoming GNOME Shell performance
+  hackfest. We also wanted to deliver a stable CI pipeline before branching
+  GNOME 3.28 off of master.
+
+- Claudio André's work on the CI pipeline deserves a spotlight. We now have
+  test jobs that run linters, sanitizers, Valgrind, and more; the tests are
+  run on up-to-date Docker images; and the reliability errors that were plaguing
+  the test runs are solved.
+
+- In addition to System.dumpHeap(), you can now dump a heap from a running
+  Javascript program by starting it with the environment variable
+  GJS_DEBUG_HEAP_OUTPUT=some_name, and sending it SIGUSR1.
+
+- heapgraph.py is a tool in the repository (not installed in distributions) for
+  analyzing and graphing heap dumps, to aid with tracking down memory leaks.
+
+- The linter CI jobs will compare your branch against GNOME/gjs@master, and fail
+  if your branch added any new linter errors. There may be false positives, and
+  the rules configuration is not perfect. If that's the case on your merge
+  request, you can skip the appropriate linter job by adding the text
+  "[skip (linter)]" in your commit message: e.g., "[skip cpplint]".
+
+- We welcomed first merge requests from several new contributors for this
+  release.
