v0.15.0

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 :: instead.

• jj rebase --skip-empty no longer abandons commits that were already empty
  before the rebase.

New features

• Partial support for commit signing. Currently you can configure jj to "keep"
  commit signatures by making new ones for rewritten commits, and to sign new
  commits when they are created.

  This comes with out-of-the-box support for the following backends:

  • GnuPG
  • SSH

  Signature verification and an explicit sign command will hopefully come soon.

• Templates now support logical operators: ||, &&, !

• Templates now support the self keyword, which is the current commit in jj log/obslog templates.

• jj show now accepts -T/--template option to render its output using
  template

• jj config list now accepts -T/--template option.

• jj git fetch now accepts -b as a shorthand for --branch, making it more
  consistent with other commands that accept a branch

• In the templating language, Timestamps now have a .local() method for
  converting to the local timezone.

• jj next/prev now infer --edit when you're already editing a non-head
  commit (a commit with children).

• A new built-in pager named :builtin is available on all platforms,
  implemented with minus

• Set config ui.log-synthetic-elided-nodes = true to make jj log include
  synthetic nodes in the graph where some revisions were elided
  (#1252,
  #2971). This may become the
  default depending on feedback.

• When creating a new workspace, the sparse patterns are now copied over from
  the current workspace.

• jj git init --colocate can now import an existing Git repository. This is
  equivalent to jj git init --git-repo=..

• jj git fetch now automatically prints new remote branches and tags by default.

• --verbose/-v is now --debug (no short option since it's not intended to be used often)

• jj move --from/--to can now be abbreviated to jj move -f/-t

• jj commit/diffedit/move/resolve/split/squash/unsquash now accept
  --tool=<NAME> option to override the default.
  #2575

• Added completions for Nushell to jj util completion

• jj branch list now supports a --tracked/-t option which can be used to
  show tracked branches only. Omits local Git-tracking branches by default.

• Commands producing diffs now accept a --context flag for the number of
  lines of context to show.

• jj commands with the -T/--template option now provide a hint containing
  defined template names when no argument is given, assisting the user in making
  a selection.

Fixed bugs

• On Windows, symlinks in the repo are now supported when Developer Mode is enabled.
  When symlink support is unavailable, they will be materialized as regular files in the
  working copy (instead of resulting in a crash).
  #2

• On Windows, the :builtin pager is now used by default, rather than being
  disabled entirely.

• Auto-rebase now preserves the shape of history even for merge commits where
  one parent is an ancestor of another.
  #2600

v0.14.0

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 revisions, so it can handle both the previous
  cases at once. The only actual difference between these three commands is the
  command syntax and their name. These names were chosen to be familiar to users
  of other version control systems, but we instead encourage all users to adopt
  jj new instead; it is more general and easier to remember than both of
  these.

  jj checkout and jj merge will no longer be shown as part of jj help, but
  will still function for now, emitting a warning about their deprecation.

  Deadline: jj checkout and jj merge will be deleted and are expected
  become a hard error later in 2024.

• jj init --git and jj init --git-repo are now deprecated and will be removed
  in the near future.

  Use jj git init instead.

Breaking changes

• (Minor) Diff summaries (e.g. jj diff -s) now use D for "Deleted" instead
  of R for "Removed". @joyously pointed out that R could also mean
  "Renamed".

• jj util completion now takes the shell as a positional argument, not a flag.
  the previous behavior is deprecated, but supported for now. it will be removed
  in the future.

New features

• jj util completion now supports powershell and elvish.

• Official binaries for macOS running on Apple Silicon (aarch64-apple-darwin)
  are now available, alongside the existing macOS x86 binaries.

• New jj op abandon command is added to clean up the operation history. Git
  refs and commit objects can be further compacted by jj util gc.

• jj util gc now removes unreachable operation, view, and Git objects.

• jj branch rename will now warn if the renamed branch has a remote branch, since
  those will have to be manually renamed outside of jj.

• jj git push gained a --tracked option, to push all the tracked branches.

• There's now a virtual root operation, similar to the virtual root
  commit. It appears at the end of jj op log.

• jj config list gained a --include-overridden option to allow
  printing overridden config values.

• jj config list now accepts --user or --repo option to specify
  config origin.

• New jj config path command to print the config file path without launching
  an editor.

• jj tag list command prints imported git tags.

• jj next and jj prev now prompt in the event of the next/previous commit
  being ambiguous, instead of failing outright.

• jj resolve now displays the file being resolved.

• jj workspace root was aliased to jj root, for ease of discoverability

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

• jj git now has an init command that initializes a git backed repo.

• New template function surround(prefix, suffix, content) is added.

Fixed bugs

• Fixed snapshots of symlinks in gitignore-d directory.
  #2878

• Fixed data loss in dirty working copy when checked-out branch is rebased or
  abandoned by Git.
  #2876

v0.13.0

Breaking changes

• jj git fetch no longer imports new remote branches as local branches. Set
  git.auto-local-branch = true to restore the old behavior.

New features

• Information about new and resolved conflicts is now printed by every command.

• jj branch has gained a new rename subcommand that allows changing a branch
  name atomically. jj branch help rename for details.

Fixed bugs

• Command aliases can now be loaded from repository config relative to the
  current working directory.

v0.12.0

Breaking changes

• The remote_branches() revset no longer includes branches exported to the Git
  repository (so called Git-tracking branches.)

• jj branch set no longer creates a new branch. Use jj branch create
  instead.

• jj init --git in an existing Git repository now errors and exits rather than
  creating a second Git store.

New features

• jj workspace add can now take multiple --revision arguments, which will
  create a new workspace with its working-copy commit on top of all the parents,
  as if you had run jj new r1 r2 r3 ....

• You can now set git.abandon-unreachable-commits = false to disable the
  usual behavior where commits that became unreachable in the Git repo are
  abandoned (#2504).

• jj new gained a --no-edit option to prevent editing the newly created
  commit. For example, jj new a b --no-edit -m Merge creates a merge commit
  without affecting the working copy.

• jj rebase now takes the flag --skip-empty, which doesn't copy over commits
  that would become empty after a rebase.

• There is a new jj util gc command for cleaning up the repository storage.
  For now, it simply runs git gc on the backing Git repo (when using the Git
  backend).

Fixed bugs

• Fixed another file conflict resolution issue where jj status would disagree
  with the actual file content.
  #2654

v0.11.0

Breaking changes

• Conflicts are now stored in a different way. Commits written by a new jj
  binary will not be read correctly by older jj binaries. The new model
  solves some performance problems with the old model. For example, jj log
  should be noticeably faster on large repos. You may need to create a new
  clone to see the full speedup.

• The remote_branches() revset now includes branches exported to the Git
  repository (so called Git-tracking branches.) Use
  remote_branches(remote=exact:"origin") to query branches of certain remote.

• Status messages are now printed to stderr.

• jj config set now interprets the value as TOML also if it's a valid TOML
  array or table. For example, jj config set --user 'aliases.n' '["new"]'

• Remote branches now have tracking or non-tracking flags. The
  git.auto-local-branch setting is applied only to newly fetched remote
  branches. Existing remote branches are migrated as follows:

  • If local branch exists, the corresponding remote branches are considered
    tracking branches.
  • Otherwise, the remote branches are non-tracking branches.

  If the deduced tracking flags are wrong, use jj branch track/untrack
  commands to fix them up.

  See automatic local branch creation
  for details.

• Non-tracking remote branches aren't listed by default. Use jj branch list --all to show all local and remote branches.

• It's not allowed to push branches if non-tracking remote branches of the same
  name exist.

• Pushing deleted/moved branches no longer abandons the local commits referenced
  by the remote branches.

• jj git fetch --branch now requires glob: prefix to expand * in branch
  name.

New features

• jj's stable release can now be installed with cargo binstall jj-cli.

• jj workspace add now takes a --revision argument.

• jj workspace forget can now forget multiple workspaces at once.

• branches()/remote_branches()/author()/committer()/description()
  revsets now support glob matching.

• jj branch delete/forget/list, and jj git push --branch now support
  string pattern syntax. The --glob option
  is deprecated in favor of glob: pattern.

• The branches/tags/git_refs/git_head template keywords now return a
  list of RefNames. They were previously pre-formatted strings.

• The new template keywords local_branches/remote_branches are added to show
  only local/remote branches.

• jj workspace add now preserves all parents of the old working-copy commit
  instead of just the first one.

• jj rebase -r gained the ability to rebase a revision A onto a descendant
  of A.

Fixed bugs

• Updating the working copy to a commit where a file that's currently ignored
  in the working copy no longer leads to a crash
  (#976).

• Conflicts in executable files can now be resolved just like conflicts in
  non-executable files (#1279).

• jj new --insert-before and --insert-after now respect immutable revisions
  (#2468).

v0.10.0

Breaking changes

• A default revset-alias function trunk() now exists. If you previously defined
  your own trunk() alias it will continue to overwrite the built-in one.
  Check revsets.toml and revsets.md
  to understand how the function can be adapted.

New features

• The ancestors() revset function now takes an optional depth argument
  to limit the depth of the ancestor set. For example, use jj log -r 'ancestors(@, 5) to view the last 5 commits.

• Support for the Watchman filesystem monitor is now bundled by default. Set
  core.fsmonitor = "watchman" in your repo to enable.

• You can now configure the set of immutable commits via
  revset-aliases.immutable_heads(). For example, set it to
  "remote_branches() | tags()" to prevent rewriting those those. Their
  ancestors are implicitly also immutable.

• jj op log now supports --no-graph.

• Templates now support an additional escape: \0. This will output a literal
  null byte. This may be useful for e.g.
  jj log -T 'description ++ "\0"' --no-graph to output descriptions only, but
  be able to tell where the boundaries are

• jj now bundles a TUI tool to use as the default diff and merge editors. (The
  previous default was meld.)

• jj split supports the --interactive flag. (This is already the default if
  no paths are provided.)

• jj commit accepts an optional list of paths indicating a subset of files to
  include in the first commit

• jj commit accepts the --interactive flag.

v0.9.0

Breaking changes

• The minimum supported Rust version (MSRV) is now 1.71.0.

• The storage format of branches, tags, and git refs has changed. Newly-stored
  repository data will no longer be loadable by older binaries.

• The : revset operator is deprecated. Use :: instead. We plan to delete the
  : form in jj 0.15+.

• The --allow-large-revsets flag for jj rebase and jj new was replaced by
  a all: before the revset. For example, use jj rebase -d 'all:foo-'
  instead of jj rebase --allow-large-revsets -d 'foo-'.

• The --allow-large-revsets flag for jj rebase and jj new can no longer be
  used for allowing duplicate destinations. Include the potential duplicates
  in a single expression instead (e.g. jj new 'all:x|y').

• The push.branch-prefix option was renamed to git.push-branch-prefix.

• The default editor on Windows is now Notepad instead of pico.

• jj will fail attempts to snapshot new files larger than 1MiB by default. This behavior
  can be customized with the snapshot.max-new-file-size config option.

• Author and committer signatures now use empty strings to represent unset
  names and email addresses. The author/committer template keywords and
  methods also return empty strings.
  Older binaries may not warn user when attempting to git push commits
  with such signatures.

• In revsets, the working-copy or remote symbols (such as @, workspace_id@,
  and branch@remote) can no longer be quoted as a unit. If a workspace or
  branch name contains whitespace, quote the name like "branch name"@remote.
  Also, these symbols will not be resolved as revset aliases or function
  parameters. For example, author(foo@) is now an error, and the revset alias
  'revset-aliases.foo@' = '@' will be failed to parse.

• The root revset symbol has been converted to function root().

• The ..x revset is now evaluated to root()..x, which means the root commit
  is no longer included.

• jj git push will now push all branches in the range remote_branches()..@
  instead of only branches pointing to @ or @-.

• It's no longer allowed to create a Git remote named "git". Use jj git remote rename to rename the existing remote.
  #1690

• Revset expression like origin/main will no longer resolve to a
  remote-tracking branch. Use main@origin instead.

New features

• Default template for jj log now does not show irrelevant information
  (timestamp, empty, message placeholder etc.) about the root commit.

• Commit templates now support the root keyword, which is true for the root
  commit and false for every other commit.

• jj init --git-repo now works with bare repositories.

• jj config edit --user and jj config set --user will now pick a default
  config location if no existing file is found, potentially creating parent directories.

• jj log output is now topologically grouped.
  #242

• jj git clone now supports the --colocate flag to create the git repo
  in the same directory as the jj repo.

• jj restore gained a new option --changes-in to restore files
  from a merge revision's parents. This undoes the changes that jj diff -r
  would show.

• jj diff/log now supports --tool <name> option to generate diffs by
  external program. For configuration, see the documentation.
  #1886

• A new experimental diff editor meld-3 is introduced that sets up Meld to
  allow you to see both sides of the original diff while editing. This can be
  used with jj split, jj move -i, etc.

• jj log/obslog/op log now supports --limit N option to show the first
  N entries.

• Added the ui.paginate option to enable/disable pager usage in commands

• jj checkout/jj describe/jj commit/jj new/jj squash can take repeated
  -m/--message arguments. Each passed message will be combined into paragraphs
  (separated by a blank line)

• It is now possible to set a default description using the new
  ui.default-description option, to use when describing changes with an empty
  description.

• jj split will now leave the description empty on the second part if the
  description was empty on the input commit.

• branches()/remote_branches()/author()/committer()/description()
  revsets now support exact matching. For example, branch(exact:main)
  selects the branch named "main", but not "maint". description(exact:"")
  selects commits whose description is empty.

• Revsets gained a new function mine() that aliases author(exact:"your_email").

• Added support for :: and .. revset operators with both left and right
  operands omitted. These expressions are equivalent to all() and ~root()
  respectively.

• jj log timestamp format now accepts .utc() to convert a timestamp to UTC.

• templates now support additional string methods .starts_with(x), .ends_with(x)
.remove_prefix(x), .remove_suffix(x), and .substr(start, end).

• jj next and jj prev are added, these allow you to traverse the history
  in a linear style. For people coming from Sapling and git-branchles
  see #2126 for
  further pending improvements.

• jj diff --stat has been implemented. It shows a histogram of the changes,
  same as git diff --stat. Fixes #2066

• jj git fetch --all-remotes has been implemented. It fetches all remotes
  instead of just the default remote

Fixed bugs

• Fix issues related to .gitignore handling of untracked directories
  #2051.

• jj config set --user and jj config edit --user can now be used outside of any repository.

• SSH authentication could hang when ssh-agent couldn't be reached
  #1970

• SSH authentication can now use ed25519 and ed25519-sk keys. They still need
  to be password-less.

• Git repository managed by the repo tool can now be detected as a "colocated"
  repository.
  #2011

v0.8.0

Breaking changes

• The jujutsu and jujutsu-lib crates were renamed to jj-cli and jj-lib,
  respectively.

• The ui.oplog-relative-timestamps option has been removed. Use the
  format_time_range() template alias instead. For details, see
  the documentation.

• Implicit concatenation of template expressions has been disabled. Use
  ++ operator, concat(), or separate() function instead.
  Example: description ++ "\n"

• jj git push will consider pushing the parent commit only when the
  current commit has no content and no description, such as right after
  a jj squash.

• The minimum supported Rust version (MSRV) is now 1.64.0.

• The heads() revset function was split up into two functions. heads()
  without arguments is now called visible_heads(). heads() with one argument
  is unchanged.

• The ui.default-revset config was renamed to revsets.log.

• The jj sparse command was split up into jj sparse list and
  jj sparse set.

• jj hide (alias for jj abandon) is no longer available. Use jj abandon
  instead.

• jj debug completion, jj debug mangen and jj debug config-schema have
  been moved from jj debug to jj util.

• jj will no longer parse br as a git_ref refs/heads/br when a branch br
  does not exist but the git_ref does (this is rare). Use br@git instead.

• jj git fetch will no longer import unrelated branches from the underlying
  Git repo.

New features

• jj git push --deleted will remove all locally deleted branches from the remote.

• jj restore without --from works correctly even if @ is a merge
  commit.

• jj rebase now accepts multiple -s and -b arguments. Revsets with
  multiple commits are allowed with --allow-large-revsets.

• jj git fetch now supports a --branch argument to fetch some of the
  branches only.

• jj config get command allows retrieving config values for use in scripting.

• jj config set command allows simple config edits like
  jj config set --repo user.email "[email protected]"

• Added ui.log-word-wrap option to wrap jj log/obslog/op log content
  based on terminal width. #1043

• Nodes in the (text-based) graphical log output now use a ◉ symbol instead
  of the letter o. The ASCII-based graph styles still use o.

• Commands that accept a diff format (jj diff, jj interdiff, jj show,
  jj log, and jj obslog) now accept --types to show only the type of file
  before and after.

• jj describe now supports --reset-author for resetting a commit's author
  to the configured user. jj describe also gained a --no-edit option to
  avoid opening the editor.

• Added latest(x[, n]) revset function to select the latest n commits.

• Added conflict() revset function to select commits with conflicts.

• jj squash AKA jj amend now accepts a --message option to set the
  description of the squashed commit on the command-line.

• The progress display on jj git clone/fetch now includes the downloaded size.

• The formatter now supports a "default" color that can override another color
  defined by a parent style.

• jj obslog and jj log now show abandoned commits as hidden.

• jj git fetch and jj git push will now use the single defined remote even
  if it is not named "origin".

• jj git push now accepts --branch and --change arguments together.

• jj git push now accepts a -r/--revisions flag to specify revisions to
  push. All branches pointing to any of the specified revisions will be pushed.
  The flag can be used together with --branch and --change.

• jj with no subcommand now defaults to jj log instead of showing help. This
  command can be overridden by setting ui.default-command.

• Description tempfiles created via jj describe now have the file extension
  .jjdescription to help external tooling detect a unique filetype.

• The shortest unique change ID prefixes and commit ID prefixes in jj log are
  now shorter within the default log revset. You can override the default by
  setting the revsets.short-prefixes config to a different revset.

• The last seen state of branches in the underlying git repo is now presented by
  jj branch list/jj log as a remote called git (e.g. main@git). They can
  also be referenced in revsets. Such branches exist in colocated repos or if
  you use jj git export.

• The new jj chmod command allows setting or removing the executable bit on
  paths. Unlike the POSIX chmod, it works on Windows, on conflicted files, and
  on arbitrary revisions. Bits other than the executable bit are not planned to
  be supported.

• jj sparse set now accepts an --edit flag which brings up the $EDITOR to
  edit sparse patterns.

• jj branch list can now be filtered by revset.

• Initial support for the Watchman filesystem monitor. Set
  core.fsmonitor = "watchman" in your repo to enable.

Fixed bugs

• Modify/delete conflicts now include context lines
  #1244.

• It is now possible to modify either side of a modify/delete conflict (any
  change used to be considered a resolution).

• Fixed a bug that could get partially resolved conflicts to be interpreted
  incorrectly.

• jj git fetch: when re-adding a remote repository that had been previously
  removed, in some situations the remote branches were not recreated.

• jj git remote rename: the git remote references were not rewritten with
  the new name. If a new remote with the old name and containing the same
  branches was added, the remote branches may not be recreated in some cases.

• jj workspace update-stale now snapshots the working-copy changes before
  updating to the new working-copy commit.

• It is no longer allowed to create branches at the root commit.

• git checkout (without using jj) in colocated repo no longer abandons
  the previously checked-out anonymous branch.
  #1042.

• jj git fetch in a colocated repo now abandons branches deleted on the
  remote, just like in a non-colocated repo.
  #864

• jj git fetch can now fetch forgotten branches even if they didn't move on
  the remote.
  #1714
  #1771

• It is now possible to jj branch forget deleted branches.
  #1537

• Fixed race condition when assigning change id to Git commit. If you've
  already had unreachable change ids, run jj debug reindex.
  #924

• Fixed false divergence on racy working-copy snapshots.
  #697,
  #1608

• In colocated repos, a bug causing conflicts when undoing branch moves (#922)
  has been fixed. Some surprising behaviors related to undoing jj git push or
  jj git fetch remain.

v0.7.0

Breaking changes

• The minimum supported Rust version (MSRV) is now 1.61.0.

• The jj touchup command was renamed to jj diffedit.

• The -i option to jj restore was removed in favor of new --from/--to
  options to jj diffedit.

• To report the situation when a change id corresponds to multiple visible
  commits, jj log now prints the change id in red and puts ?? after it.
  Previously, it printed the word "divergent".

• jj log prefixes commit descriptions with "(empty)" when they contain no
  change compared to their parents.

• The author/committer templates now display both name and email. Use
  author.name()/committer.name() to extract the name.

• Storage of the "HEAD@git" reference changed and can now have conflicts.
  Operations written by a new jj binary will have a "HEAD@git" reference that
  is not visible to older binaries.

• The description template keyword is now empty if no description set.
  Use if(description, description, "(no description set)\n") to get back
  the previous behavior.

• The template.log.graph and template.commit_summary config keys were
  renamed to templates.log and templates.commit_summary respectively.

• If a custom templates.log template is set, working-copy commit will
  no longer be highlighted automatically. Wrap your template with
  label(if(current_working_copy, "working_copy"), ...) to label the
  working-copy entry.

• The ui.relative-timestamps option has been removed. Use the
  format_timestamp() template alias instead. For details on showing relative
  timestamps in jj log and jj show, see the documentation.

• jj op log now shows relative timestamps by default. To disable, set
  ui.oplog-relative-timestamps to false.

• The global --no-commit-working-copy is now called --ignore-working-copy.

• The diff.format config option is now called ui.diff.format. The old name
  is still supported for now.

• merge-tools.<name>.edit-args now requires $left/$right parameters.
  The default is edit-args = ["$left", "$right"].

• The builtin jj update and jj up aliases for jj checkout have been
  deleted.

• Change IDs are now rendered using letters from the end of the alphabet (from
  'z' through 'k') instead of the usual hex digits ('0' through '9' and 'a'
  through 'f'). This is to clarify the distinction between change IDs and commit
  IDs, and to allow more efficient lookup of unique prefixes. This change
  doesn't affect the storage format; existing repositories will remain usable.

New features

• The default log format now uses the committer timestamp instead of the author
  timestamp.

• jj log --summary --patch now shows both summary and diff outputs.

• jj git push now accepts multiple --branch/--change arguments

• jj config list command prints values from config and config edit opens
  the config in an editor.

• jj debug config-schema command prints out JSON schema for the jj TOML config
  file format.

• jj resolve --list can now describe the complexity of conflicts.

• jj resolve now notifies the user of remaining conflicts, if any, on success.
  This can be prevented by the new --quiet option.

• Per-repository configuration is now read from .jj/repo/config.toml.

• Background colors, bold text, and underlining are now supported. You can set
  e.g. color.error = { bg = "red", bold = true, underline = true } in your
  ~/.jjconfig.toml.

• The empty condition in templates is true when the commit makes no change to
  the three compared to its parents.

• branches([needle]) revset function now takes needle as an optional
  argument and matches just the branches whose name contains needle.

• remote_branches([branch_needle[, remote_needle]]) now takes branch_needle
  and remote_needle as optional arguments and matches just the branches whose
  name contains branch_needle and remote contains remote_needle.

• jj git fetch accepts repeated --remote arguments.

• Default remotes can be configured for the jj git fetch and jj git push
  operations ("origin" by default) using the git.fetch and git.push
  configuration entries. git.fetch can be a list if multiple remotes must
  be fetched from.

• jj duplicate can now duplicate multiple changes in one go. This preserves
  any parent-child relationships between them. For example, the entire tree of
  descendants of abc can be duplicated with jj duplicate abc:.

• jj log now highlights the shortest unique prefix of every commit and change
  id and shows the rest in gray. To customize the length and style, use the
  format_short_id() template alias. For details, see
  the documentation.

• jj print was renamed to jj cat. jj print remains as an alias.

• In content that goes to the terminal, the ANSI escape byte (0x1b) is replaced
  by a "␛" character. That prevents them from interfering with the ANSI escapes
  jj itself writes.

• jj workspace root prints the root path of the current workspace.

• The [alias] config section was renamed to [aliases]. The old name is
  still accepted for backwards compatibility for some time.

• Commands that draw an ASCII graph (jj log, jj op log, jj obslog) now
  have different styles available by setting e.g. ui.graph.style = "curved".

• jj split accepts creating empty commits when given a path. jj split .
  inserts an empty commit between the target commit and its children if any,
  and jj split any-non-existent-path inserts an empty commit between the
  target commit and its parents.

• Command arguments to ui.diff-editor/ui.merge-editor can now be specified
  inline without referring to [merge-tools] table.

• jj rebase now accepts a new --allow-large-revsets argument that allows the
  revset in the -d argument to expand to several revisions. For example,
  jj rebase -s B -d B- -d C now works even if B is a merge commit.

• jj new now also accepts a --allow-large-revsets argument that behaves
  similarly to jj rebase --allow-large-revsets.

• jj new --insert-before inserts the new commit between the target commit and
  its parents.

• jj new --insert-after inserts the new commit between the target commit and
  its children.

• author/committer templates now support .username(), which leaves out the
  domain information of .email().

• It is now possible to change the author format of jj log with the
  format_short_signature() template alias. For details, see
  the documentation.

• Added support for template aliases. New symbols and functions can be
  configured by template-aliases.<name> = <expression>. Be aware that
  the template syntax isn't documented yet and is likely to change.

Fixed bugs

• When sharing the working copy with a Git repo, we used to forget to export
  branches to Git when only the working copy had changed. That's now fixed.

• Commit description set by -m/--message is now terminated with a newline
  character, just like descriptions set by editor are.

• The -R/--repository path must be a valid workspace directory. Its
  ancestor directories are no longer searched.

• Fixed a crash when trying to access a commit that's never been imported into
  the jj repo from a Git repo. They will now be considered as non-existent if
  referenced explicitly instead of crashing.

• Fixed handling of escaped characters in .gitignore (only keep trailing spaces
  if escaped properly).

• jj undo now works after jj duplicate.

• jj duplicate followed by jj rebase of a tree containing both the original
  and duplicate commit no longer crashes. The fix should also resolve any remaining
  instances of #27.

• Fix the output of jj debug completion --help by reversing fish and zsh text.

• Fixed edge case in jj git fetch when a pruned branch is a prefix of another
  branch.
