Herald added a reviewer: hg-reviewers.
Herald added a subscriber: mercurial-patches.

REVISION SUMMARY
  After having written the notes, I realized that the added points contain changes
  that were part of the 5.4.2 release. These were never included in any release
  notes. I asked on IRC whether they should be added to this file or not, but
  didn’t get an answer to this question. If they should not be added here, I can
  remove them.

REPOSITORY
  rHG Mercurial

BRANCH
  stable
