About

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

Release highlights

  • git.subprocess is now enabled by default, improving compatibility with Git
    fetches and pushes by spawning an external git process. Users can opt out
    of this by setting git.subprocess = false, but this will likely be removed
    in a future release. Please report any issues you run into.

Breaking changes

  • Bookmark name to be created/updated is now parsed as a revset
    symbol. Quotation may be needed in addition to shell
    quotes. Example: jj bookmark create -r@- "'name with space'"

  • jj bookmark create, jj bookmark set and jj bookmark move onto a hidden
    commit make it visible.

  • jj bookmark forget now untracks any corresponding remote bookmarks instead
    of forgetting them, since forgetting a remote bookmark can be unintuitive.
    The old behavior is still available with the new --include-remotes flag.

  • jj fix now always sets the working directory of invoked tools to be the
    workspace root, instead of the working directory of the jj fix.

  • The ui.allow-filesets configuration option has been removed.
    The "fileset" language has been enabled by default since v0.20.

  • templates.annotate_commit_summary is renamed to templates.file_annotate,
    and now has an implicit self parameter of type AnnotationLine, instead of
    Commit. All methods on Commit can be accessed with commit.method(), or
    self.commit().method().

Deprecations

  • This release takes the first steps to make target revision required in
    bookmark create, bookmark move and bookmark set. Those commands will display
    a warning if the user does not specify target revision explicitly. In the near
    future those commands will fail if target revision is not specified.

  • The signing.sign-all config option has been deprecated in favor of
    signing.behavior. The new option accepts drop (never sign), keep (preserve
    existing signatures), own (sign own commits), or force (sign all commits).
    Existing signing.sign-all = true translates to signing.behavior = "own", and
    false translates to "keep". Invalid configuration is now an error.

New features

  • The new jj sign and jj unsign commands allow for signing/unsigning commits.
    jj sign supports configuring the default revset through revsets.sign when
    no --revisions arguments are provided.

  • jj git fetch now supports string pattern syntax
    on --remote option and git.fetch configuration.

  • Template functions truncate_start() and truncate_end() gained an optional
    ellipsis parameter; passing this prepends or appends the ellipsis to the
    content if it is truncated to fit the maximum width.

  • Templates now support stringify(x) function and string method
    .escape_json(). The latter serializes the string in JSON format. It is
    useful for making machine-readable templates by escaping problematic
    characters like \n.

  • Templates now support trim(), trim_start() and trim_end() methods
    which remove whitespace from the start and end of a String type.

  • The description of commits backed out by jj backout can now be configured
    using templates.backout_description.

  • New AnnotationLine templater type. Used in templates.file_annotate.
    Provides self.commit(), .content(), .line_number(), and
    .first_line_in_hunk().

  • Templates now have format_short_operation_id(id) function for users to
    customize the default operation id representation.

  • The jj init/jj revert stubs that print errors can now be overridden with
    aliases. All of jj clone/init/revert add a hint to a generic error.

  • Help text is now colored (when stdout is a terminal).

  • Commands that used to suggest --ignore-immutable now print the number of
    immutable commits that would be rewritten if used and a link to the docs.

  • jj undo now shows a hint when undoing an undo operation that the user may
    be looking for jj op restore instead.

Fixed bugs

  • jj status now shows untracked files under untracked directories.
    #5389

  • Added workaround for the bug that untracked files are ignored when watchman is
    enabled. #5728

  • The signing.backends.ssh.allowed-signers configuration option will now
    expand ~/ to $HOME/.
    #5626

  • config-schema.json now allows arrays of strings for the settings ui.editor
    and ui.diff.tool.

  • config-schema.json now allows an array of strings or nested table for the
    ui.pager setting.
