on GitHub

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
