 == 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 ==
 
 == Miscellaneous ==
 
  * sslutil: use proper attribute to select python 3.7+
  * typing: suppress a few pyi-errors with more recent pytype
  * ci: bump pytype to 2022.03.29
  * bundlespec: add documentation about existing option
  * subrepo: avoid opening console window for non-native subrepos on Windows

+ * perf-unbundle: improve compatibility
