[martinvonz]

About

jj is a Git-compatible version control system that is both simple and powerful. See
the installation instructions to get started.

Release highlights

• Switched to the mimalloc memory allocator for better multi-threaded
  performance.

Breaking changes

• The following deprecated command options have been removed:

  • jj commit --reset-author/--author
  • jj describe --no-edit/--edit/--reset-author/--author
  • jj git push --allow-new
  • jj metaedit --update-committer-timestamp

• The following deprecated config options have been removed:

  • git.auto-local-bookmark
  • git.push-new-bookmarks

Deprecations

• jj evolog no longer supports legacy commit predecessors recorded in jj <
  0.30.

New features

• Shell completions now surface descriptions for custom aliases,
  revset-aliases, template-aliases, and fileset-aliases. Descriptions are
  extracted from the .doc field of the alias definition if it is a table
  with .doc and .definition properties.

• jj show now accepts multiple revisions, showing all of them one after the
  other, behaving closer to git show.

• jj git fetch now generates evolution history based on change IDs. If change
  IDs are preserved by the remote, local descendant revisions will be rebased
  onto the rewritten parents.

• Added jj util backend name command that prints the commit backend being used
  in the current repo.

• Added edit-invocation-mode config option for diff editors (e.g.
  jj diffedit, jj split). When set to "file-by-file", the editor is
  launched once per changed file, making it possible to use per-file tools like
  vimdiff for editing.

Fixed bugs

• jj git remote add now reports an error instead of panicking when the
  remote name is empty or contains whitespace.
  #9099

• Color-words diffs are now shown as separate before and after lines when color
  output is disabled, making piped or redirected diffs readable.
  #5894

• jj bookmark forget no longer prints Forgot N local bookmarks. when no
  local bookmarks were actually forgotten (e.g. when only an untracked remote
  bookmark matched). #9181.

• The builtin_log_redacted template now also redacts workspace names.
