v0.46.0

### About

jj is a Git-compatible version control system that is both simple and powerful. See
the [installation instructions](https://docs.jj-vcs.dev/v0.46.0/install-and-setup/) to get started.

### Release highlights

* Jujutsu can now colocate workspaces besides the default one by creating Git
  worktrees. Use `jj workspace add --[no-]colocate` and the setting
  `git.colocate` to control this.

### Breaking changes

* The minimum supported `git` command version is now 2.42.0, up from 2.41.0.
  `jj workspace add` uses `git worktree add --orphan`, which was added in
  2.42.0.

* The minimum supported Rust version (MSRV) is now 1.97.1.

* `jj bisect run` now runs some consistency checks before proceeding to bisect.
  This helps ensure that the command can tell good and bad revisions apart,
  and that the working copy does go from bad to good over the provided revset.
  Use the new flag `--trust-endpoints` to disable these checks.

* `jj split` now opens a single editor session to edit descriptions for the
  split commits.

* `jj undo` and `jj redo` now refuse to undo/redo an operation that was
  performed in another workspace. Use `--allow-cross-workspace` to undo/redo
  it anyway.

* `jj workspace list`/`root` no longer omit unreachable paths. All recorded
  paths are now shown, with warnings displayed in `jj workspace root`.

* The `List.get()`, `.first()`, and `.last()` template functions now return
  `Option<T>` instead of throwing an error on out-of-bounds access.

### New features

* `jj workspace add` supports `--colocate`/`--no-colocate` flags to control
  whether a Git worktree is created alongside the workspace. The default
  colocates when the current workspace is colocated and the `git.colocate`
  config is `true`. `jj workspace forget` removes the corresponding Git
  worktree when one exists.

* `jj git colocation status`/`enable`/`disable` now work on child
  workspaces. `status` correctly reports colocation state and includes
  the workspace name. `enable` creates a Git worktree and `disable`
  removes it, allowing colocation to be toggled after workspace
  creation.

* `jj workspace remove` removes a workspace and its directory from disk. The
  working-copy state is snapshotted into a commit before removal.

* Added commands `jj file edit` and `jj file delete` for editing files in any
  revision without needing to change the working copy.

* `jj git push` now supports pushing to multiple remotes at the same time.
  This can be configured via `git.push` set to a string pattern
  or array of string patterns, or with the repeatable `--remote` flag,
  which also accepts string patterns.

* The default target revisions for `jj git push` can now be configured via
  `revsets.git-push`.

* Added the `TreeEntry.normal_value()` template method and the `TreeValue` type
  to access resolved tree values, formatted as their full object IDs, including
  Git submodule commit IDs.

* Diff hunk headers now include nearby source symbols for many common
  programming and markup languages.

* `fix.tools.<name>.line-range-args` (replaces `line-range-arg`) is an array of
  string template args to pass to the fix tool. This is more flexible in cases
  where you need to pass multiple arguments to the tool, such as separate args
  for the range start and range end.

* `jj run` now uses the sparse patterns from the workspace it's run from.
  Use the `--sparse-patterns` option to control this behavior (evaluated
  per each `jj run` invocation).

* `jj util diff <path1> <path2>` to compare files on disk.

* Aliases now support setting `aliases.<name>.enabled = false`, which will
  disable them. This can be used to disable built-in aliases or disable aliases
  in later layers (such as repo config files).

* `ui.editor` now supports `$path` and `$line` substitution variables. Example:
  `ui.editor = ["emacs", "+$line", "$path"]`

* `fill` template function now supports an additional named parameter
  `break_words`, that allows specifying if the template should break words
  longer than `width` passed in the input to ensure no words overflow the
  specified width.

* The `json()` template function now supports map literals: `json({'key' =>
  value})`

* The hunk headers of `diff.color-words.conflict = "pair"` now include the
  conflict labels of the compared terms.

### Fixed bugs

* On Windows, `jj` no longer hangs when a subprocess needs to prompt the user,
  such as `ssh` asking for a key passphrase or for confirmation of an unknown
  host key. Subprocesses started from a terminal now inherit its console, rather
  than being given an invisible one by `CREATE_NO_WINDOW` for the prompt to
  disappear into.

  [#8547](https://github.com/jj-vcs/jj/issues/8547)

* On Windows, `jj git colocation enable` and `jj git colocation disable` no
  longer fail with "Access is denied (os error 5)" when the Git repository
  contains pack files.
  [#8661](https://github.com/jj-vcs/jj/issues/8661)

* `jj undo` of `jj workspace forget` now correctly preserves the workspace's
  recorded path. Previously the path metadata was lost, leaving the workspace
  in a broken state after undo.
  [#9991](https://github.com/jj-vcs/jj/issues/9991)

* `at_operation()` can now be used with operations that are not ancestors of
  the current operation (e.g. sibling operations created by concurrent
  commands). Previously, evaluating such expressions failed if they resolved
  to commits missing from the current operation's index.

* `.gitignore` files are now respected even if they aren't materialized in the
  working copy because they are excluded by the sparse patterns. Previously,
  ignored files could become tracked in a sparse working copy.
  [#2289](https://github.com/jj-vcs/jj/issues/2289)

* In-tree ignore files (`.gitignore`) are no longer read through symlinks,
  matching `git` behavior. Such files are now silently skipped instead of having
  their symlink target applied. `$GIT_DIR/info/exclude` and `core.excludesFile`
  are unaffected and still follow symlinks, as `git` does.
  [#7161](https://github.com/jj-vcs/jj/issues/7161)

* `jj workspace list` templates are now labeled with `workspace name`,
  `workspace root`, etc.
