== Default Format Change ==

These changes affect newly created repositories (or new clones) done with

Mercurial 6.3.

== New Experimental Features ==

== Bug Fixes ==

 * shelve: demonstrate that the state is different across platforms (issue6735)

 * shelve: in test for trailing whitespace, strip commit (issue6735)

 * shelve: remove strip and rely on prior state (issue6735)

 * tests: fix http-bad-server expected errors for python 3.10 (issue6643)

 * status: let `--no-copies` override `ui.statuscopies`

 * releasenotes: use re.MULTILINE mode when checking admonitions

 * rhg: fallback to slow path on invalid patterns in hgignore

 * Fix a bunch of leftover str/bytes issues from Python 3 migration

 * keepalive: ensure `close_all()` actually closes all cached connections

 * lfs: fix blob corruption when tranferring with workers on posix

 * lfs: avoid closing connections when the worker doesn't fork

 * dirstate-v2: update constant that wasn't kept in sync

 * dirstate-v2: fix edge case where entries aren't sorted

 * upgrade: no longer keep all revlogs in memory at any point

 * rust-status: save new dircache even if just invalidated

 * dirstate-v2: hash the source of the ignore patterns as well

 * rhg: fallback when encountering ellipsis revisions

 * shelve: handle empty parents and nodestoremove in shelvedstate (issue6748)

 * profile: prevent a crash when line number is unknown

 * tags-fnode-cache: do not repeatedly open the filelog in a loop

 * tags-fnode-cache: skip building a changectx in getfnode

 * rust: create wrapper struct to reduce `regex` contention issues

== Backwards Compatibility Changes ==

 * chg worker processes will now correctly load per-repository configuration

   when given a both a relative `--repository` path and an alternate working

   directory via `--cwd`. A side-effect of this change is that these workers

   will now return an error if hg cannot find the current working directory,

   even when a different directory is specified via `--cwd`.

 * phase: rename the requirement for internal-phase from `internal-phase` to `use-internal-phase` (see 74fb1842f8b962cf03d7cd5b841dbcf2ae065587)

== Internal API Changes ==
