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.
