=== Backwards Compatibility Changes ===

* The infinitepush extension is believed to be unused, and will be deleted at
  the end of 2020 unless users contact mercurial-devel@mercurial-scm.org.

* 'hg grep' now searches working copy file contents by default. We recognize
  this is a significant change from past behavior, but surveys of large bodies
  of users indicated nobody used (and almost nobody understood) the previous
  no-flags behavior of 'hg grep'. The new behavior aligns with the behavior
  most users expected (including hg's maintainers), which also happens to be
  the behavior of 'git grep'. Given that the old behavior was confusing to the
  point of being unusable, we were comfortable changing this behavior.

=== API Changes ===

* 'mercurial.hg.update*' and 'mercurial.merge.update' now expect a value from
  a set of NAMED_CONSTANTS ('merge.UPDATECHECK_*' constants) rather than a
  collection of magic strings. As of now, the values are the same, but code
  should be prepared for these values to change in the future.

* 'mercurial.hg.updatetotally' is now more thorough about checking its
  'updatecheck' keyword argument. Previously invalid values would have used
  the configured default updatecheck method, but now will raise ValueError.

* 'mercurial.bookmarks.bmstore' no longer has a convenience method for looking
  up changectx instances from a bookmark name. Use
  'repo[repo.bookmarks[name]]' intead of 'repo.bookmarks.changectx(name)'.


=== commands ===
 * amend: add option to update to the current user
 * amend: enable support for closing the branch
 * amend: enable support for using the secret phase
 * bookmarks: actual fix for race condition deleting bookmark
 * bookmarks: remove changectx() method from bmstore (API)

 * log: populate keywords if specified in custom -Tjson(...) or -Tcbor(...)
 * merge: replace magic strings with NAMED_CONSTANTS (API)
 * push: support config option to require revs be specified when running push

 * revlog: add a 'sidedata' parameters to addrevision

24. Mercurial 5.2 (2019-11-05)

Regularly scheduled feature release. An overview of new features available. This is a regularly-scheduled quarterly feature release.

24.1. Backwards Compatibility Changes

* The infinitepush extension is believed to be unused, and will be deleted at

* 'hg grep' now searches working copy file contents by default. We recognize

  • this is a significant change from past behavior, but surveys of large bodies of users indicated nobody used (and almost nobody understood) the previous no-flags behavior of 'hg grep'. The new behavior aligns with the behavior most users expected (including hg's maintainers), which also happens to be the behavior of 'git grep'. Given that the old behavior was confusing to the point of being unusable, we were comfortable changing this behavior.

24.2. API Changes

* 'mercurial.hg.update*' and 'mercurial.merge.update' now expect a value from

  • a set of NAMED_CONSTANTS ('merge.UPDATECHECK_*' constants) rather than a collection of magic strings. As of now, the values are the same, but code should be prepared for these values to change in the future.

* 'mercurial.hg.updatetotally' is now more thorough about checking its

  • 'updatecheck' keyword argument. Previously invalid values would have used

    the configured default updatecheck method, but now will raise ValueError.

* 'mercurial.bookmarks.bmstore' no longer has a convenience method for looking

  • up changectx instances from a bookmark name. Use 'repo[repo.bookmarks[name]]' intead of 'repo.bookmarks.changectx(name)'.

24.3. commands

  • amend: add option to update to the current user
  • amend: enable support for closing the branch
  • amend: enable support for using the secret phase
  • bookmarks: actual fix for race condition deleting bookmark
  • bookmarks: remove changectx() method from bmstore (API)

  • merge: replace magic strings with NAMED_CONSTANTS (API)
  • push: support config option to require revs be specified when running push

24.4. core

  • exchange: abort on pushing bookmarks pointing to secret changesets (issue6159)
