Trylle

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

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.

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/.

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)

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 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

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.

Thanks to the people who made this release happen!
