New Experimental Features#

Bug Fixes#

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

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

  • 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

  • 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

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)
