v0.37.0

### About

jj is a Git-compatible version control system that is both simple and powerful. See
the [installation instructions](https://jj-vcs.github.io/jj/v0.37.0/install-and-setup/) to get started.

### Release highlights

* A new syntax for referring to hidden and divergent change IDs is available:
  `xyz/n` where `n` is a number. For instance, `xyz/0` refers to the latest
  version of `xyz`, while `xyz/1` refers to the previous version of `xyz`.
  This allows you to perform actions like `jj restore --from xyz/1 --to xyz` to
  restore `xyz` to its previous contents, if you made a mistake.

  For divergent changes, the numeric suffix will always be shown in the log,
  allowing you to disambiguate them in a similar manner.

### Breaking changes

* [String patterns](docs/revsets.md#string-patterns) in revsets, command
  arguments, and configuration are now parsed as globs by default. Use
  `substring:` or `exact:` prefix as needed.

* `remotes.<name>.auto-track-bookmarks` is now parsed the same way they
  are in revsets and can be combined with logical operators.

* `jj bookmark track`/`untrack` now accepts `--remote` argument. If omitted, all
  remote bookmarks matching the bookmark names will be tracked/untracked. The
  old `<bookmark>@<remote>` syntax is deprecated in favor of `<bookmark>
  --remote=<remote>`.

* On Windows, symlinks that point to a path with `/` won't be supported. This
  path is [invalid on Windows](https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file#naming-conventions).

* The template alias `format_short_change_id_with_hidden_and_divergent_info(commit)`
  has been replaced by `format_short_change_id_with_change_offset(commit)`.

* The following deprecated config options have been removed:
  - `git.push-bookmark-prefix`
  - `ui.default-description`
  - `ui.diff.format`
  - `ui.diff.tool`

* The deprecated `commit_id.normal_hex()` template method has been removed.

* Template expansion that did not produce a terminating newline will not be
  fixed up to provide one by `jj log`, `jj evolog`, or `jj op log`.

* The `diff` conflict marker style can now use `\\\\\\\` markers to indicate
  the continuation of a conflict label from the previous line.

### Deprecations

* The `git_head()` and `git_refs()` functions will be removed from revsets and
  templates. `git_head()` should point to the `first_parent(@)` revision in
  colocated repositories. `git_refs()` can be approximated as
  `remote_bookmarks(remote=glob:*) | tags()`.

### New features

* Updated the executable bit representation in the local working copy to allow
  ignoring executable bit changes on Unix. By default we try to detect the
  filesystem's behavior, but this can be overridden manually by setting
  `working-copy.exec-bit-change = "respect" | "ignore"`.

* `jj workspace add` now also works for empty destination directories.

* `jj git remote` family of commands now supports different fetch and push URLs.

* `[colors]` table now supports `dim = true` attribute.

* In color-words diffs, context line numbers are now rendered with decreased
  intensity.

* Hidden and divergent commits can now be unambiguously selected using their
  change ID combined with a numeric suffix. For instance, if there are two
  commits with change ID `xyz`, then one can be referred to as `xyz/0` and the
  other can be referred to as `xyz/1`. These suffixes are shown in the log when
  necessary to make a change ID unambiguous.

* `jj util gc` now prunes unreachable files in `.jj/repo/store/extra` to save
  disk space.

* Early version of a `jj file search` command for searching for a pattern in
  files (like `git grep`).

* Conflict labels now contain information about where the sides of a conflict
  came from (e.g. `nlqwxzwn 7dd24e73 "first line of description"`).

* `--insert-before` now accepts a revset that resolves to an empty set when
  used with `--insert-after`. The behavior is similar to `--onto`.

* `jj tag list` now supports `--sort` option.

* `TreeDiffEntry` type now has a `display_diff_path()` method that formats
  renames/copies appropriately.

* `TreeDiffEntry` now has a `status_char()` method that returns
  single-character status codes (M/A/D/C/R).

* `CommitEvolutionEntry` type now has a `predecessors()` method which
  returns the predecessor commits (previous versions) of the entry's commit.

* `CommitEvolutionEntry` type now has a  `inter_diff()` method  which
  returns a `TreeDiff` between the entry's commit and its predecessor version.
  Optionally accepts a fileset literal to limit the diff.

* `jj file annotate` now reports an error for non-files instead of succeeding
  and displaying no content.

* `jj workspace forget` now warns about unknown workspaces instead of failing.

### Fixed bugs

* Broken symlink on Windows. [#6934](https://github.com/jj-vcs/jj/issues/6934).

* Fixed failure on exporting moved/deleted annotated tags to Git. Moved tags are
  exported as lightweight tags.

* `jj gerrit upload` now correctly handles mixed explicit and implicit
  Change-Ids in chains of commits ([#8219](https://github.com/jj-vcs/jj/pull/8219))

* `jj git push` now updates partially-pushed remote bookmarks accordingly.
  [#6787](https://github.com/jj-vcs/jj/issues/6787)

* Fixed problem of loading large Git packfiles.
  https://github.com/GitoxideLabs/gitoxide/issues/2265

* The builtin pager won't get stuck when stdin is redirected.

* `jj workspace add` now prevents creating an empty workspace name.

* Fixed checkout of symlinks pointing to themselves or `.git`/`.jj` on Unix. The
  problem would still remain on Windows if symlinks are enabled.
  [#8348](https://github.com/jj-vcs/jj/issues/8348)

* Fixed a bug where jj would fail to read git delta objects from pack files.
