Jujutsu

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 exter

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

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

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• The commit_summary_no_branches template is superseded by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

Fixed bugs

• jj status no longer scans through the entire history to look for ancestors with conflicts.

Breaking changes

• The default template aliases were replaced as follows:

  • builtin_op_log_root(op_id: OperationId) ->
    format_root_operation(root: Operation)
  • builtin_log_root(change_id: ChangeId, commit_id: CommitId) ->
    format_root_commit(root: Commit)
  • builtin_change_id_with_hidden_and_divergent_info ->
    format_short_change_id_with_hidden_and_divergent_info(commit: Commit)

• The --revision option of jj rebase is renamed to --revisions. The short
  alias -r is still supported.

New features

• The list of conflicted paths is printed whenever the working copy changes.
  This can be

Deprecations

• jj move was deprecated in favor of jj squash.

Breaking changes

• The git_head template keyword now returns an optional value instead of a
  list of 0 or 1 element.

• The jj sparse set --edit/--reset flags were split up into jj sparse edit/reset subcommands respectively.

• The jj sparse subcommands now parse and print patterns as workspace-relative
  paths.

• The jj log command no longer uses the default revset when a path is specified.

New features

• Config now supports rgb hex colors (in the form #rrggbb) wherever existing color names are supported.

No code changes (fixing Rust Cargo.toml stuff).

Breaking changes

• The minimum supported Rust version (MSRV) is now 1.76.0.

• The on-disk index format changed. New index files will be created
  automatically, but it can fail if the repository is co-located and predates
  Git GC issues #815. If
  reindexing failed, you'll need to clean up corrupted operation history by
  jj op abandon ..<bad operation ID>.

• Dropped support for the "legacy" graph-drawing style. Use "ascii" for a very
  similar result.

• The default log output no longer lists all tagged heads. Set revsets.log = "@ | ancestors(immutable_heads().., 2) | heads(immutable_heads())" to restore
  the old behavior.

• Dropped support for the deprecated : revset operator. Use :: inst

Deprecations

• jj checkout and jj merge are both deprecated; use jj new instead to
  replace both of these commands in all instances.

  Rationale: jj checkout and jj merge both implement identical
  functionality, which is a subset of jj new. checkout creates a new working
  copy commit on top of a single specified revision, i.e. with one parent.
  merge creates a new working copy commit on top of at least two specified
  revisions, i.e. with two or more parents.

  The only difference between these commands and jj new, which also creates
  a new working copy commit, is that new can create a working copy commit on
  top of any arbitrary number of revi
