About

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

Release highlights

  • Improved Git push/fetch compatibility by spawning an external git process.
    This can be enabled by the git.subprocess=true config knob, and will be the
    default in a future release.

  • jj log can now show cryptographic commit signatures. The output can be
    controlled by the ui.show-cryptographic-signatures=true config knob.

Breaking changes

  • jj abandon now deletes bookmarks pointing to the revisions to be abandoned.
    Use --retain-bookmarks to move bookmarks backwards. If deleted bookmarks
    were tracking remote bookmarks, the associated bookmarks (or branches) will be
    deleted from the remote on jj git push --all.
    #3505

  • jj init --git and jj init --git-repo have been removed. They were
    deprecated in early 2024. Use jj git init instead.

  • The following deprecated commands have been removed:

    • jj cat is replaced by jj file show.
    • jj chmod is replaced by jj file chmod.
    • jj files is replaced by jj file list.

  • The deprecated -l short alias for --limit in jj log, jj op log
    and jj obslog has been removed. The -n short alias can be used instead.

  • The deprecated --siblings options for jj split has been removed.
    jj split --parallel can be used instead.

  • The deprecated fix.tool-command config option has been removed.

  • In colocated repos, the Git index now contains the changes from all parents
    of the working copy instead of just the first parent (HEAD). 2-sided
    conflicts from the merged parents are now added to the Git index as conflicts
    as well.

  • The following change introduced in 0.25.0 is reverted:

    • jj config list now prints inline tables { key = value, .. } literally.
      Inner items of inline tables are no longer merged across configuration
      files.

  • jj resolve will now attempt to resolve all conflicted files instead of
    resolving the first conflicted file. To resolve a single file, pass a file
    path to jj resolve.

  • jj util mangen is replaced with jj util install-man-pages, which can
    install man pages for all jj subcommands to a given path.

  • In jj config list template, value is now typed as ConfigValue, not as
    String serialized in TOML syntax.

  • jj git remote add/set-url now converts relative Git remote path to
    absolute path.

  • jj log/op log now applies -n/--limit before the items are reversed.
    Rationale: It's more useful to see the N most recent commits/operations, and
    is more performant. The old behavior can be achieved by jj log .. | head.
    #5403

  • Upgraded scm-record from v0.4.0 to v0.5.0. See release notes at
    https://github.com/arxanas/scm-record/releases/tag/v0.5.0.

  • The builtin pager is switched to
    streampager. It can handle large
    inputs better and can be configured.

  • Conflicts materialized in the working copy before jj 0.19.0 may no longer
    be parsed correctly. If you are using version 0.18.0 or earlier, check out a
    non-conflicted commit before upgrading to prevent issues.

Deprecations

New features

  • jj git {push,clone,fetch} can now spawn an external git subprocess, via
    the git.subprocess = true config knob. This provides an alternative that,
    when turned on, fixes SSH bugs when interacting with Git remotes due to
    libgit2s limitations #4979.

  • jj describe now accepts --edit.

  • jj evolog and jj op log now accept --reversed.

  • jj restore now supports -i/--interactive selection.

  • jj file list now supports templating.

  • There is a new builtin_op_log_oneline template alias you can pass to jj op log -T for a more compact output. You can use format_operation_oneline and
    format_snapshot_operation_oneline to customize parts of it.

  • New template function config(name) to access to configuration variable from
    template.

  • New template function pad_centered() to center content within a minimum
    width.

  • Templater now supports list.filter(|x| ..) method.

  • The diff commit template keyword now supports custom formatting via
    diff.files(). For example, diff.files().map(|e| e.path().display()) prints
    changed file paths.

  • The diff.stat() template method now provides methods to get summary values.

  • jj log can now show cryptographic commit signatures. The output can be
    controlled by the ui.show-cryptographic-signatures=true config knob. The
    signature template can be customized using
    format_detailed_cryptographic_signature(signature) and
    format_short_cryptographic_signature(signature).

  • New git.sign-on-push config option to automatically sign commits which are
    being pushed to a Git remote.

  • New git.push-new-bookmarks config option to push new bookmarks without
    --allow-new.

  • jj status now shows untracked files when they reside directly under a
    tracked directory. There's still an issue that files under untracked
    directories aren't listed. #5389

  • New merge-tools.<TOOL>.diff-expected-exit-codes config option to suppress
    warnings from tools exiting with non-zero exit codes.

  • New fix.tools.TOOL.enabled config option to enable/disable tools. This is
    useful for defining disabled tools in user configuration that can be enabled
    in individual repositories with one config setting.

  • Added --into flag to jj restore, similarly to jj squash and jj absorb. It is equivalent to --to, but --into is the recommended name.

  • Italic text is now supported. You can set e.g. color.error = { fg = "red", italic = true } in your config.

  • New author_name/author_email/committer_name/committer_email(pattern)
    revset functions to match either name or email field explicitly.

  • New subject(pattern) revset function that matches first line of commit
    descriptions.

  • Conditional configuration now supports --when.commands to change
    configuration based on subcommand.

  • The Jujutsu documentation site now publishes a schema for the official
    configuration file, which can be integrated into your editor for autocomplete,
    inline errors, and more.
    Please see the documentation for more
    on this.

Fixed bugs

  • jj git fetch with multiple remotes will now fetch from all remotes before
    importing refs into the jj repo. This fixes a race condition where the
    treatment of a commit that is found in multiple fetch remotes depended on the
    order the remotes were specified.

  • Fixed diff selection by external tools with jj split/commit -i FILESETS.
    #5252

  • Conditional configuration now applies when initializing new repository.
    #5144

  • [diff.<format>] configuration now applies to .diff().<format>() commit
    template methods.

  • Conflicts at the end of files which don't end with a newline character are
    now materialized in a way that can be parsed correctly.
    #3968

  • Bookmark and remote names written by jj git clone to
    revset-aliases.'trunk()' are now escaped if necessary.
    #5359

v0.25.0

About

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

Release highlights

It's the holidays, and this release was overall pretty quiet, without many major
changes. Two select improvements:

  • Improvements to configuration management, including support for conditional
    variables     in config files.

  • Large files in the working copy will no longer cause commands to fail; instead
    the large files will remain intact but untracked in the working copy.

Breaking changes

  • Configuration variables are no longer "stringly" typed. For example, true is
    not converted to a string "true", and vice versa.

  • The following configuration variables are now parsed strictly:
    colors.<labels>, git.abandon-unreachable-commits,
    git.auto-local-bookmark, git.push-bookmark-prefix, revsets.log,
    revsets.short-prefixes signing.backend, operation.hostname,
    operation.username, ui.allow-init-native, ui.color,
    ui.default-description, ui.progress-indicator, ui.quiet, user.email,
    user.name

  • jj config list now prints inline tables { key = value, .. } literally.
    Inner items of inline tables are no longer merged across configuration files.
    See the table syntax documentation for details.

  • jj config edit --user now opens a file even if $JJ_CONFIG points to a
    directory. If there are multiple config files, the command will fail.

  • jj config set no longer accepts a bare string value that looks like a TOML
    expression. For example, jj config set NAME '[foo]' must be quoted as jj config set NAME '"[foo]"'.

  • The deprecated [alias] config section is no longer respected. Move command
    aliases to the [aliases] section.

  • jj absorb now abandons the source commit if it becomes empty and has no
    description.

Deprecations

  • --config-toml=TOML is deprecated in favor of --config=NAME=VALUE and
    --config-file=PATH.

  • The Signature.username() template method is deprecated for
    Signature().email().local().

New features

  • jj command no longer fails due to new working-copy files larger than the
    snapshot.max-new-file-size config option. It will print a warning and large
    files will be left untracked.

  • Configuration files now support conditional variables.

  • New command options --config=NAME=VALUE and --config-file=PATH to set
    string value without quoting and to load additional configuration from files.

  • Templates now support the >=, >, <=, and < relational operators for
    Integer types.

  • A new Email template type is added. Signature.email() now returns an Email
    template type instead of a String.

  • Adds a new template alias commit_timestamp(commit) which defaults to the
    committer date.

  • Conflict markers are now allowed to be longer than 7 characters, allowing
    conflicts to be materialized and parsed correctly in files which already
    contain lines that look like conflict markers.

  • New $marker_length variable to allow merge tools to support longer conflict
    markers (equivalent to "%L" for Git merge drivers).

  • jj describe now accepts a JJ: ignore-rest line that ignores everything
    below it, similar to a "scissor line" in git. When editing multiple commits,
    only ignore until the next JJ: describe line.

Fixed bugs

  • The $NO_COLOR environment variable must now be non-empty to be respected.

  • Fixed incompatible rendering of empty hunks in git/unified diffs. #5049

  • Fixed performance of progress bar rendering when fetching from Git remote. #5057

  • jj config path --user no longer creates new file at the default config path.

  • On Windows, workspace paths (printed by jj root) no longer use UNC-style
    \\?\ paths unless necessary.

  • On Windows, jj git clone now converts local Git remote path to
    slash-separated path.

  • jj resolve no longer removes the executable bit on resolved files when using
    an external merge tool.

v0.24.0

About

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

Release highlights

  • 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].)

Security fixes

Breaking changes

  • Revset function names can no longer start with a number.

  • Evaluation error of revsets.short-prefixes configuration is now reported.

  • The HEAD@git symbol no longer resolves to the Git HEAD revision. Use
    git_head() or @- revset expression instead. The git_head template
    keyword now returns a boolean.

  • Help command doesn't work recursively anymore, i.e. jj workspace help root
    doesn't work anymore.

  • The color label op_log from the [colors] config section now only
    applies to the op log and not to the other places operations are displayed. In
    almost all cases, if you configured op_log before, you should use the new
    operation label instead.

  • Default operation log template now shows end times of operations instead of
    start times.

Deprecations

  • git.auto-local-bookmark replaces git.auto-local-branch. The latter remains
    supported for now (at lower precedence than the former).

New features

  • Added diff options to ignore whitespace when comparing lines. Whitespace
    changes are still highlighted.

  • New command jj simplify-parents will remove redundant parent edges.

  • jj squash now supports -f/-t shorthands for --from/--[in]to.

  • Initial support for shallow Git repositories has been implemented. However,
    deepening the history of a shallow repository is not yet supported.

  • jj git clone now accepts a --depth <DEPTH> option, which
    allows to clone the repository with a given depth.

  • New command jj file annotate that annotates files line by line. This is similar
    in functionality to git blame. Invoke the command with jj file annotate <file_path>.
    The output can be customized via the templates.annotate_commit_summary
    config variable.

  • jj bookmark list gained a --remote REMOTE option to display bookmarks
    belonging to a remote. This option can be combined with --tracked or
    --conflicted.

  • New command jj config unset that unsets config values. For example,
    jj config unset --user user.name.

  • jj help now has the flag --keyword (shorthand -k), which can give help
    for some keywords (e.g. jj help -k revsets). To see a list of the available
    keywords you can do jj help --help.

  • New at_operation(op, expr) revset can be used in order to query revisions
    based on historical state.

  • String literals in filesets, revsets and templates now support hex bytes
    (with \e as escape / shorthand for \x1b).

  • New coalesce(revsets...) revset which returns commits in the first revset
    in the revsets list that does not evaluate to none().

  • New template function raw_escape_sequence(...) preserves escape sequences.

  • Timestamp objects in templates now have after(date) -> Boolean and
    before(date) -> Boolean methods for comparing timestamps to other dates.

  • New template functions pad_start(), pad_end(), truncate_start(), and
    truncate_end() are added.

  • Add a new template alias builtin_log_compact_full_description().

  • Added the config settings diff.color-words.context and diff.git.context to
    control the default number of lines of context shown.

Fixed bugs

  • Error on trunk() revset resolution is now handled gracefully.
    #4616

  • Updated the built-in diff editor scm-record to version
    0.4.0, which
    includes multiple fixes.

v0.22.0

@martinvonz martinvonz
v0.22.0
67c2ae0

View all tags
v0.22.0

Breaking changes

  • Fixing #4239 means the
    ordering of some messages have changed.

  • Invalid ui.graph.style configuration is now an error.

  • The builtin template branch_list has been renamed to bookmark_list as part
    of the jj branch deprecation.

Deprecations

  • jj branch has been deprecated in favor of jj bookmark.

    Rationale: Jujutsu's branches don't behave like Git branches, which a
    confused many newcomers, as they expected a similar behavior given the name.
    We've renamed them to "bookmarks" to match the actual behavior, as we think
    that describes them better, and they also behave similar to Mercurial's
    bookmarks.

  • jj obslog is now called jj evolution-log/jj evolog. jj obslog remains
    as an alias.

  • jj unsquash has been deprecated in favor of jj squash and
    jj diffedit --restore-descendants.

    Rationale: jj squash can be used in interactive mode to pull
    changes from one commit to another, including from a parent commit
    to a child commit. For fine-grained dependent diffs, such as when
    the parent and the child commits must successively modify the same
    location in a file, jj diffedit --restore-descendants can be used
    to set the parent commit to the desired content without altering the
    content of the child commit.

  • The git.push-branch-prefix config has been deprecated in favor of
    git.push-bookmark-prefix.

  • conflict() and file() revsets have been renamed to conflicts() and files()
    respectively. The old names are still around and will be removed in a future
    release.

New features

  • The new config option snapshot.auto-track lets you automatically track only
    the specified paths (all paths by default). Use the new jj file track
    command to manually tracks path that were not automatically tracked. There is
    no way to list untracked files yet. Use git status in a colocated workspace
    as a workaround.
    #323

  • jj fix now allows fixing unchanged files with the --include-unchanged-files flag. This
    can be used to more easily introduce automatic formatting changes in a new
    commit separate from other changes.

  • jj workspace add now accepts a --sparse-patterns=<MODE> option, which
    allows control of the sparse patterns for a newly created workspace: copy
    (inherit from parent; default), full (full working copy), or empty (the
    empty working copy).

  • New command jj workspace rename that can rename the current workspace.

  • jj op log gained an option to include operation diffs.

  • jj git clone now accepts a --remote <REMOTE NAME> option, which
    allows to set a name for the remote instead of using the default
    origin.

  • jj op undo now reports information on the operation that has been undone.

  • jj squash: the -k flag can be used as a shorthand for --keep-emptied.

  • CommitId / ChangeId template types now support .normal_hex().

  • jj commit and jj describe now accept --author option allowing to quickly change
    author of given commit.

  • jj diffedit, jj abandon, and jj restore now accept a --restore-descendants
    flag. When used, descendants of the edited or deleted commits will keep their original
    content.

  • jj git fetch -b <remote-git-branch-name> will now warn if the branch(es)
    can not be found in any of the specified/configured remotes.

  • jj split now lets the user select all changes in interactive mode. This may be used
    to keeping all changes into the first commit while keeping the current commit
    description for the second commit (the newly created empty one).

  • Author and committer names are now yellow by default.

Fixed bugs

  • Update working copy before reporting changes. This prevents errors during reporting
    from leaving the working copy in a stale state.

  • Fixed panic when parsing invalid conflict markers of a particular form.
    (#2611)

  • Editing a hidden commit now makes it visible.

  • The present() revset now suppresses missing working copy error. For example,
    present(@) evaluates to none() if the current workspace has no
    working-copy commit.

v0.21.0

Breaking changes

  • next/prev will no longer infer when to go into edit mode when moving from
    commit to commit. It now either follows the flags --edit|--no-edit or it
    gets the mode from ui.movement.edit.

Deprecations

  • jj untrack has been renamed to jj file untrack.

New features

  • Add new boolean config knob, ui.movement.edit for controlling the behaviour
    of prev/next. The flag turns edit mode on and off permanently when set
    respectively to true or false.

  • All diff formats except --name-only now include information about copies and
    moves. So do external diff tools in file-by-file mode. jj status also
    includes information about copies and moves.

  • Color-words diff has gained an option to display complex changes as separate
    lines    . It's enabled by default. To
    restore the old behavior, set diff.color-words.max-inline-alternation = -1.

  • A tilde (~) at the start of the path will now be expanded to the user's home
    directory when configuring a signing.key for SSH commit signing.

  • When reconfiguring the author, warn that the working copy won't be updated

Fixed bugs

  • Release binaries for Intel Macs have been restored. They were previously
    broken due to using a sunset version of GitHub's macOS runners (but nobody had
    previously complained.)

Note to packagers

  • jj now links libgit2 statically by default. To use dynamic linking, you
    need to set the environment variable LIBGIT2_NO_VENDOR=1 while compiling.
    (#4163)

Breaking changes

  • jj rebase --skip-empty has been renamed to jj rebase --skip-emptied

  • jj backout --revision has been renamed to jj backout --revisions.
    The short alias -r is still supported.

  • The default immutable_heads() set
    now includes untracked_remote_branches() with the assumption that untracked
    branches aren't managed by you. Therefore, untracked branches are no longer
    displayed in jj log by default.

  • Updated defaults for graph node symbol templates templates.log_node and
    templates.op_log_node.

  • The "fileset" language is now enabled by default. It can
    still be disable by setting ui.allow-filesets=false.

  • On jj git fetch/import, commits referred to by HEAD@git are no longer
    preserved. If a checked-out named branch gets deleted locally or remotely, the
    corresponding commits will be abandoned.

  • jj --at-op=@ no longer merges concurrent operations if explicitly specified.

  • jj obslog -p no longer shows diffs at non-partial squash operations.
    Previously, it showed the same diffs as the second predecessor.

Deprecations

  • The original configuration syntax for jj fix is now deprecated in favor of
    one that allows defining multiple tools that can affect different filesets.
    These can be used in combination for now. See jj help fix for details.

New features

  • External diff tools can now be configured to invoke the tool on each file
    individually instead of being passed a directory by setting
    merge-tools.$TOOL.diff-invocation-mode="file-by-file" in config.toml.

  • In git diffs, word-level hunks are now highlighted with underline. See diff
    colors and styles     for customization.

  • New .diff().<format>() commit template methods are added. They can be used
    in order to show diffs conditionally. For example,
    if(current_working_copy, diff.summary()).

  • jj git clone and jj git init with an existing git repository adds the
    default branch of the remote as repository settings for
    revset-aliases."trunk()".`

  • jj workspace forget now abandons the workspace's working-copy commit if it
    was empty.

  • jj backout now includes the backed out commit's subject in the new commit
    message.

  • jj backout can now back out multiple commits at once.

  • jj git clone some/nested/path now creates the full directory tree for
    nested destination paths if they don't exist.

  • String patterns now support case‐insensitive matching by suffixing any
    pattern kind with -i. mine() uses case‐insensitive matching on your email
    address unconditionally. Only ASCII case folding is currently implemented,
    but this will likely change in the future.

  • String patterns now support regex:"pattern".

  • New tracked_remote_branches() and untracked_remote_branches() revset
    functions can be used to select tracked/untracked remote branches.

  • The file() revset function now accepts fileset as argument.

  • New diff_contains() revset function can be used to search diffs.

  • New command jj operation diff that can compare changes made between two
    operations.

  • New command jj operation show that can show the changes made in a single
    operation.

  • New config setting git.private-commits to prevent commits from being pushed.

  • The default commit description template
    can now be configured by templates.draft_commit_description.

  • jj fix can now be configured to run different tools on different filesets.
    This simplifies the use case of configuring code formatters for specific file
    types. See jj help fix for details.

  • Added revset functions author_date and committer_date.

  • jj describe can now update the description of multiple commits.

Fixed bugs

  • jj status will show different messages in a conflicted tree, depending
    on the state of the working commit. In particular, if a child commit fixes
    a conflict in the parent, this will be reflected in the hint provided
    by jj status

  • jj diff --git no longer shows the contents of binary files.

  • Windows binaries no longer require vcruntime140.dll to be installed
    (normally through Visual Studio.)

  • On quit, the builtin pager no longer waits for all outputs to be discarded.

  • jj branch rename no longer shows a warning in colocated repos.

v0.19.0

Breaking changes

  • In revset aliases, top-level kind:pattern expression is now parsed as
    modifier. Surround with parentheses if it should be parsed as string/file
    pattern.

  • Dropped support for automatic upgrade of repo formats used by versions before
    0.12.0.

  • jj fix now defaults to the broader revset -s reachable(@, mutable())
    instead of -s @.

  • Dropped support for deprecated jj branch delete/forget --glob option.

  • jj branch set now creates new branch if it doesn't exist. Use jj branch move to ensure that the target branch already exists.
    #3584

Deprecations

  • Replacing -l shorthand for --limit with -n in jj log, jj op log
    and jj obslog.

  • jj split --siblings is deprecated in favor of jj split --parallel (to
    match jj parallelize).

  • A new jj file subcommand now replaces several existing uncategorized
    commands, which are deprecated.

    • jj file show replaces jj cat.
    • jj file chmod replaces jj chmod.
    • jj file list replaces jj files.

New features

  • Support background filesystem monitoring via watchman triggers enabled with
    the core.watchman.register_snapshot_trigger = true config.

  • Show paths to config files when configuration errors occur.

  • jj fix now supports configuring the default revset for -s using the
    revsets.fix config.

  • The descendants() revset function now accepts an optional depth argument;
    like the ancestors() depth argument, it limits the depth of the set.

  • Revset/template aliases now support function overloading.
    #2966

  • Conflicted files are individually simplified before being materialized.

  • The jj file subcommand now contains several existing file utilities.

    • jj file show, replacing jj cat.
    • jj file chmod replacing jj chmod.
    • jj file list replacing jj files.

  • New command jj branch move let you update branches by name pattern or source
    revision.

  • New diff option jj diff --name-only allows for easier shell scripting.

  • In color-words diffs, hunks are now highlighted with underline. See diff
    colors and styles     for customization.

  • jj git push -c <arg> can now accept revsets that resolve to multiple
    revisions. This means that jj git push -c xyz -c abc is now equivalent to
    jj git push -c 'all:(xyz | abc)'.

  • jj prev and jj next have gained a --conflict flag which moves you
    to the next conflict in a child commit.

  • New command jj git remote set-url that sets the url of a git remote.

  • Author timestamp is now reset when rewriting discardable commits (empty
    commits with no description) if authored by the current user.
    #2000

  • jj commit now accepts --reset-author option to match jj describe.

  • jj squash now accepts a --keep-emptied option to keep the source commit.

Fixed bugs

  • jj git push now ignores immutable commits when checking whether a
    to-be-pushed commit has conflicts, or has no description / committer / author
    set. #3029

  • jj will look for divergent changes outside the short prefix set even if it
    finds the change id inside the short prefix set.
    #2476

v0.18.0

Breaking changes

  • Dropped support for ui.default-revset config (replaced by revsets.log in
    0.8.0).

  • The commit_summary_no_branches template is superseded by
    templates.branch_list.

  • jj split will now refuse to split an empty commit.

  • jj config list now uses multi-line strings and single-quoted strings in the
    output when appropriate.

  • jj config get/list/set now parse name argument as TOML
    key    . Quote meta characters as needed.
    Example: jj config get "revset-aliases.'trunk()'"

  • When updating the working copy away from an empty and undescribed commit, it
    is now abandoned even if it is a merge commit.

  • If a new working-copy commit is created because the old one was abandoned, and
    the old commit was merge, then the new commit will now also be.
    #2859

  • jj new's --insert-before/--insert-after options must now be set for each
    commit the new commit will be inserted before/after. Previously, those options
    were global flags and specifying them once would insert the new commit before/
    after all the specified commits.

Deprecations

  • Attempting to alias a built-in command now gives a warning, rather than being
    silently ignored.

New features

  • jj branch list/tag list now accept -T/--template option. The tag list
    prints commit summary along with the tag name by default.

  • Conflict markers now include an explanation of what each part of the conflict
    represents.

  • ui.color = "debug" prints active labels alongside the regular colored output.

  • jj branch track now show conflicts if there are some.

  • A new revset reachable(srcs, domain) will return all commits that are
    reachable from srcs within domain.

  • There are now prebuilt binaries for aarch64-linux-unknown-musl.
    Note, these are cross compiled and currently untested.
    We plan on providing fully tested builds later once our CI system allows it.

  • Added new revsets mutable() and immutable().

  • Upgraded scm-record from v0.2.0 to v0.3.0. See release notes at
    https://github.com/arxanas/scm-record/releases/tag/v0.3.0

  • New command jj fix that can be configured to update commits by running code
    formatters (or similar tools) on changed files. The configuration schema and
    flags are minimal for now, with a number of improvements planned (for example,
    #3800 and
    #3801).

  • jj new's --insert-before and --insert-after options can now be used
    simultaneously.

  • jj git push now can push commits with empty descriptions with the
    --allow-empty-description flag

Fixed bugs

  • Previously, jj git push only made sure that the branch is in the expected
    location on the remote server when pushing a branch forward (as opposed to
    sideways or backwards). Now, jj git push makes a safety check in all cases
    and fails whenever jj git fetch would have introduced a conflict.

    In other words, previously branches that moved sideways or backward were
    pushed similarly to Git's git push --force; now they have protections
    similar to git push --force-with-lease (though not identical to it, to match
    the behavior of jj git fetch). Note also that because of the way jj git fetch works, jj does not suffer from the same problems as Git's git push --force-with-lease in situations when git fetch is run in the background.

  • When the working copy commit becomes immutable, a new one is automatically created
    on top of it to avoid letting the user edit the immutable one.

  • jj config list now properly escapes TOML keys (#1322).

  • Files with conflicts are now checked out as executable if all sides of the
    conflict are executable.

  • The progress bar (visible when using e.g. jj git clone) clears the
    remainder of the cursor row after drawing rather than clearing the entire row
    before drawing, eliminating the "flicker" effect seen on some terminals.
