Jujutsu v0.43.0 release notes

jj is a Git-compatible version control system that is both simple and powerful. See the installation instructions to get started.

jj run allows you to run a command over a set of changes, each with their own private working copy; the commands may update the working copy and changes/conflicts are propagated accordingly, e.g., jj run -- cargo check --all-features or jj run -- cargo fix behaves as one might expect.

The deprecated git_head() and git_refs() functions have been removed from revsets and templates.
Git-like symbols (e.g. refs/heads/main) are no longer resolved to revisions. Use the bookmark/tag <name> or <name>@<remote> syntax instead.
The deprecated ui.revsets-use-glob-by-default option has been removed.
jj bookmark track/untrack no longer supports <kind>:<bookmark>@<remote> patterns. However, the <bookmark>@<remote> symbol syntax is still supported. #9226

jj show now supports --reversed flag.
jj now looks for config files in /etc/jj.
jj config gc will delete configuration of deleted/moved repos from ~/.config/jj/repos folder. #9362
jj run allows you to run a command over a set of changes, each with their own private working copy; the commands may update the working copy and changes/conflicts are propagated accordingly, e.g., jj run -- cargo check --all-features or jj run -- cargo fix behaves as one might expect.
jj gerrit upload now supports the -o (--option) flag, which works like git push -o (--push-option).
jj git fetch now rebases the descendants of revisions that were rewritten based on their change IDs. Previously, when multiple bookmarked revisions existed in a stack, those rewritten revisions and their descendants wouldn't always be rebased. Note that immutable descendants will not be rebased.
Add a forks() revset function that yields all commits with more than 1 child.
colors config now supports crossed-out text styling with { crossed-out = true }.

On Windows, querying a path's file identity no longer follows symbolic links, matching the behavior on Unix. Previously a symlink shared the identity of its target, so two symlinks pointing at the same target were treated as the same file. This identity check is used when writing the working copy to detect aliases of the reserved .git and .jj directories. #8924
jj now creates a new working-copy revision during snapshotting if the working copy was immutable. Previously, the new revision was created immediately after the working copy became immutable. #7751 #9338
jj git remote add now warns if the new remote exactly matches an existing remote's fetch URL or effective push URL. #413
Fixed corrupt loose Git objects on Intel Raptor Lake CPU and aarch64. Previously, jj could report a successful commit even though git fsck would later fail with incorrect data check, corrupt loose object, or missing blob, and later jj operations could fail with corrupt deflate stream.

Thanks to the people who made this release happen!
