About

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

Release highlights

  • Jujutsu can now colocate workspaces besides the default one by creating Git
    worktrees. Use jj workspace add --[no-]colocate and the setting
    git.colocate to control this.

Breaking changes

  • The minimum supported git command version is now 2.42.0, up from 2.41.0.
    jj workspace add uses git worktree add --orphan, which was added in
    2.42.0.

  • The minimum supported Rust version (MSRV) is now 1.97.1.

  • jj bisect run now runs some consistency checks before proceeding to bisect.
    This helps ensure that the command can tell good and bad revisions apart,
    and that the working copy does go from bad to good over the provided revset.
    Use the new flag --trust-endpoints to disable these checks.

  • jj split now opens a single editor session to edit descriptions for the
    split commits.

  • jj undo and jj redo now refuse to undo/redo an operation that was
    performed in another workspace. Use --allow-cross-workspace to undo/redo
    it anyway.

  • jj workspace list/root no longer omit unreachable paths. All recorded
    paths are now shown, with warnings displayed in jj workspace root.

  • The List.get(), .first(), and .last() template functions now return
    Option<T> instead of throwing an error on out-of-bounds access.

New features

  • jj workspace add supports --colocate/--no-colocate flags to control
    whether a Git worktree is created alongside the workspace. The default
    colocates when the current workspace is colocated and the git.colocate
    config is true. jj workspace forget removes the corresponding Git
    worktree when one exists.

  • jj git colocation status/enable/disable now work on child
    workspaces. status correctly reports colocation state and includes
    the workspace name. enable creates a Git worktree and disable
    removes it, allowing colocation to be toggled after workspace
    creation.

  • jj workspace remove removes a workspace and its directory from disk. The
    working-copy state is snapshotted into a commit before removal.

  • Added commands jj file edit and jj file delete for editing files in any
    revision without needing to change the working copy.

  • jj git push now supports pushing to multiple remotes at the same time.
    This can be configured via git.push set to a string pattern
    or array of string patterns, or with the repeatable --remote flag,
    which also accepts string patterns.

  • The default target revisions for jj git push can now be configured via
    revsets.git-push.

  • Added the TreeEntry.normal_value() template method and the TreeValue type
    to access resolved tree values, formatted as their full object IDs, including
    Git submodule commit IDs.

  • Diff hunk headers now include nearby source symbols for many common
    programming and markup languages.

  • fix.tools.<name>.line-range-args (replaces line-range-arg) is an array of
    string template args to pass to the fix tool. This is more flexible in cases
    where you need to pass multiple arguments to the tool, such as separate args
    for the range start and range end.

  • jj run now uses the sparse patterns from the workspace it's run from.
    Use the --sparse-patterns option to control this behavior (evaluated
    per each jj run invocation).

  • jj util diff <path1> <path2> to compare files on disk.

  • Aliases now support setting aliases.<name>.enabled = false, which will
    disable them. This can be used to disable built-in aliases or disable aliases
    in later layers (such as repo config files).

  • ui.editor now supports $path and $line substitution variables. Example:
    ui.editor = ["emacs", "+$line", "$path"]

  • fill template function now supports an additional named parameter
    break_words, that allows specifying if the template should break words
    longer than width passed in the input to ensure no words overflow the
    specified width.

  • The json() template function now supports map literals: json({'key' => value})

  • The hunk headers of diff.color-words.conflict = "pair" now include the
    conflict labels of the compared terms.

Fixed bugs

  • On Windows, jj no longer hangs when a subprocess needs to prompt the user,
    such as ssh asking for a key passphrase or for confirmation of an unknown
    host key. Subprocesses started from a terminal now inherit its console, rather
    than being given an invisible one by CREATE_NO_WINDOW for the prompt to
    disappear into.
    #6745
    #8547

  • On Windows, jj git colocation enable and jj git colocation disable no
    longer fail with "Access is denied (os error 5)" when the Git repository
    contains pack files.
    #8661

  • jj undo of jj workspace forget now correctly preserves the workspace's
    recorded path. Previously the path metadata was lost, leaving the workspace
    in a broken state after undo.
    #9991

  • at_operation() can now be used with operations that are not ancestors of
    the current operation (e.g. sibling operations created by concurrent
    commands). Previously, evaluating such expressions failed if they resolved
    to commits missing from the current operation's index.

  • .gitignore files are now respected even if they aren't materialized in the
    working copy because they are excluded by the sparse patterns. Previously,
    ignored files could become tracked in a sparse working copy.
    #2289

  • In-tree ignore files (.gitignore) are no longer read through symlinks,
    matching git behavior. Such files are now silently skipped instead of having
    their symlink target applied. $GIT_DIR/info/exclude and core.excludesFile
    are unaffected and still follow symlinks, as git does.
    #7161

  • jj workspace list templates are now labeled with workspace name,
    workspace root, etc.
