v0.35.0

### 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/v0.35.0/install-and-setup/) to get started.

### Release highlights

* Workspaces can now have their own separate configuration. For instance, you
  can use `jj config set --workspace` to update a configuration option only in
  the current workspace.

* After creating a local bookmark, it is now possible to use `jj bookmark track`
  to associate the bookmark with a specific remote before pushing it. When
  pushing a tracked bookmark, it is not necessary to use `--allow-new`.

* The new `jj git colocation enable` and `jj git colocation disable` commands
  allow converting between colocated and non-colocated workspaces.

### Breaking changes

* The `remote_bookmarks(remote=pattern)` revset now includes Git-tracking
  bookmarks if the specified `pattern` matches `git`. The default is
  `remote=~exact:"git"` as before.

* The deprecated flag `--summary` of `jj abandon` has been removed.

* The deprecated command `jj backout` has been removed, use `jj revert` instead.

* The following deprecated config options have been removed:
  - `signing.sign-all`
  - `core.watchman.register_snapshot_trigger`
  - `diff.format`

### Deprecations

 * `jj bisect run --command <cmd>` is deprecated in favor of
   `jj bisect run -- <cmd>`.

 * `jj metaedit --update-committer-timestamp` was renamed to
   `jj metaedit --force-rewrite` since the old name (and help text)
   incorrectly suggested that the committer name and email would _not_
   be updated.

### New features

* Workspaces may have an additional layered configuration, located at
  `.jj/workspace-config.toml`. `jj config` subcommands which took layer options
  like `--repo` now also support `--workspace`.

* `jj bookmark track` can now associate new local bookmarks with remote.
  Tracked bookmarks can be pushed without `--allow-new`.
  [#7072](https://github.com/jj-vcs/jj/issues/7072)

* The new `jj git colocation` command provides sub-commands to show the
  colocation state (`status`), to convert a non-colocated workspace into
  a colocated workspace (`enable`), and vice-versa (`disable`).

* New `jj tag set`/`delete` commands to create/update/delete tags locally.
  Created/updated tags are currently always exported to Git as lightweight
  tags. If you would prefer them to be exported as annotated tags, please give
  us feedback on [#7908](https://github.com/jj-vcs/jj/issues/7908).

* Templates now support a `.split(separator, [limit])` method on strings to
  split a string into a list of substrings.

* `-G` is now available as a short form of `--no-graph` in `jj log`, `jj evolog`,
  `jj op log`, `jj op show` and `jj op diff`.

* `jj metaedit` now accepts `-m`/`--message` option to non-interactively update
  the change description.

* The `CryptographicSignature.key()` template method now also works for SSH
  signatures and returns the corresponding public key fingerprint.

* Added `template-aliases.empty_commit_marker`. Users can override this value in
  their config to change the "(empty)" label on empty commits.

* Add support for `--when.workspaces` config scopes.

* Add support for `--when.hostnames` config scopes. This allows configuration to
  be conditionally applied based on the hostname set in `operation.hostname`.

* `jj bisect run` accepts the command and arguments to pass to the command
  directly as positional arguments, such as
  `jj bisect run --range=..main -- cargo check --all-targets`.

* Divergent changes are no longer marked red in immutable revisions. Since the
  revision is immutable, the user shouldn't take any action, so the red color
  was unnecessarily alarming.

* New commit template keywords `local`/`remote_tags` to show only local/remote
  tags. These keywords may be useful in non-colocated Git repositories where
  local and exported `@git` tags can point to different revisions.

*  `jj git clone` now supports the `--branch` option to specify the branch(es)
  to fetch during clone. If present, the first matching branch is used as the
  working-copy parent.

* Revsets now support logical operators in string patterns.

### Fixed bugs

* `jj metaedit --author-timestamp` twice with the same value no longer
edits the change twice in some cases.

* `jj squash`: fixed improper revision rebase when both `--insert-after` and
  `--insert-before` were used.

* `jj undo` can now revert "fetch"/"import" operation that involves tag updates.
  [#6325](https://github.com/jj-vcs/jj/issues/6325)

* Fixed parsing of `files(expr)` revset expression including parentheses.
  [#7747](https://github.com/jj-vcs/jj/issues/7747)

* Fixed `jj describe --stdin` to append a final newline character.
