v0.29.0

About

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

Release highlights

• Experimental support for transferring the change ID to/from Git remotes behind configuration
  setting git.write-change-id-header. If this is enabled, the change ID will be stored in the Git
  commit itself (in a commit header called change-id), which means it will be transferred by
  regular git push etc. This is an evolving feature that currently defaults to "false". This
  default will likely change in the future as we gain confidence with forge support and user
  expectations.

Breaking changes

• jj git push -c/--change no longer moves existing local bookmarks.

• The editor-*.jjdescription files passed to your editor by e.g. jj describe
  are now written to your system's temporary directory instead of .jj/repo/.

Deprecations

• git.subprocess = false has been deprecated, and the old libgit2
  code path for fetches and pushes will be removed entirely in 0.30.
  Please report any remaining issues you have with the Git
  subprocessing path.

• ui.default-description has been deprecated, and will be migrated to
  template-aliases.default_commit_description. Please also consider using
  templates.draft_commit_description,
  and/or templates.commit_trailers.

• On macOS, config.toml files in ~/Library/Application Support/jj are
  deprecated; one should instead use $XDG_CONFIG_HOME/jj
  (defaults to ~/.config/jj)

New features

• Color-words diff has gained an option to compare conflict pairs without
  materializing.

• jj show patches can now be suppressed with --no-patch.

• Added ui.bookmark-list-sort-keys setting to configure default sort keys for the
  jj bookmark list command.

• New signed revset function to filter for cryptographically signed commits.

• jj describe, jj commit, jj new, jj squash and jj split add the
  commit trailers, configured in the commit_trailers template, to the commit
  description. Use cases include DCO Sign Off and Gerrit Change Id.

• Added duplicate_description template, which allows customizing the descriptions
  of the commits jj duplicate creates.

• jj absorb can now squash a deleted file if it was added by one of the
  destination revisions.

• Added ui.streampager.show-ruler setting to configure whether the ruler should be
  shown when the builtin pager starts up.

• jj git fetch now warns instead of erroring for unknown git.fetch remotes
  if other remotes are available.

• Commit objects in templates now have trailers() -> List<Trailer>, the Trailer
  objects have key() -> String and value() -> String.

• jj config edit will now roll back to previous version if a syntax error has been introduced in the new config.

• When using dynamic command-line completion, revision names will be completed
  in more complex expressions. For example, typing
  jj log -r first-bookmark..sec and then pressing Tab could complete the
  expression to first-bookmark..second-bookmark.

Fixed bugs

• Fixed crash on change-delete conflict resolution. #6250

• The builtin diff editor now tries to preserve unresolved conflicts. #4963

• Fixed bash and zsh shell completion when completing aliases of multiple arguments. #5377

Packaging changes

• Jujutsu now uses zlib-rs, a fast compression library written in Rust. Packagers should remove any dependency on CMake and drop the packaging Cargo feature.

Heads up, the installation instructions link is broken, it should be https://jj-vcs.github.io/jj/v0.29.0/install-and-setup/ instead of https://jj-vcs.github.io/jj/v0.2.0/install-and-setup/

[martinvonz]

Thanks! Fixed now.

Ah, I see the link is fixed on this copy of the release notes (#6473) but the primary version that most people will see (https://github.com/jj-vcs/jj/releases) and (https://github.com/jj-vcs/jj/releases/tag/v0.29.0) still has the old link. (I do not know enough about GitHub Releases to know if fixing the latter page is possible or not).

[martinvonz]

Ah, fixed there too now. Thanks for letting us know.
