About

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

Release highlights

  • New jj absorb command automatically squashes changes from the current commit into relevant ancestor commits.

  • Experimental dynamic shell completions have been added; see the docs for configuration.

  • jj duplicate now accepts --destination/--insert-before/--insert-after.

  • Some deprecated commands have been removed (jj move, jj checkout, jj merge).

Breaking changes

  • jj move has been removed. It was deprecated in 0.16.0.

  • jj checkout and the built-in alias jj co have been removed.
    It was deprecated in 0.14.0.

  • jj merge has been removed. It was deprecated in 0.14.0.

  • jj git push no longer pushes new bookmarks by default. Use --allow-new to
    bypass this restriction.

  • Lines prefixed with "JJ:" in commit descriptions and in sparse patterns (from
    jj sparse edit) are now stripped even if they are not immediately followed
    by a space. #5004

Deprecations

New features

  • Templates now support the == and != logical operators for Boolean,
    Integer, and String types.

  • New command jj absorb that moves changes to stack of mutable revisions.

  • New command jj util exec that can be used for arbitrary aliases.

  • jj rebase -b can now be used with the --insert-after and --insert-before
    options, like jj rebase -r and jj rebase -s.

  • A preview of improved shell completions was added. Please refer to the
    documentation
    to activate them. They additionally complete context-dependent, dynamic values
    like bookmarks, aliases, revisions, operations and files.

  • Added the config setting snapshot.auto-update-stale for automatically
    running jj workspace update-stale when applicable.

  • jj duplicate now accepts --destination, --insert-after and
    --insert-before options to customize the location of the duplicated
    revisions.

  • jj log now displays the working-copy branch first.

  • New fork_point() revset function can be used to obtain the fork point
    of multiple commits.

  • The tags() revset function now takes an optional pattern argument,
    mirroring that of bookmarks().

  • Several commands now support -f/-t shorthands for --from/--to:

    • diff
    • diffedit
    • interdiff
    • op diff
    • restore

  • New ui.conflict-marker-style config option to change how conflicts are
    materialized in the working copy. The default option ("diff") renders
    conflicts as a snapshot with a list of diffs to apply to the snapshot.
    The new "snapshot" option renders conflicts as a series of snapshots, showing
    each side and base of the conflict. The new "git" option replicates Git's
    "diff3" conflict style, meaning it is more likely to work with external tools,
    but it doesn't support conflicts with more than 2 sides.

  • New merge-tools.<TOOL>.conflict-marker-style config option to override the
    conflict marker style used for a specific merge tool.

  • New merge-tools.<TOOL>.merge-conflict-exit-codes config option to allow a
    merge tool to exit with a non-zero code to indicate that not all conflicts
    were resolved.

  • jj simplify-parents now supports configuring the default revset when no
    --source or --revisions arguments are provided with the
    revsets.simplify-parents config.

Fixed bugs

  • jj config unset <TABLE-NAME> no longer removes a table (such as [ui].)
