Release v0.12.0 · jj-vcs/jj

The remote_branches() revset no longer includes branches exported to the Git
repository (so called Git-tracking branches.)
jj branch set no longer creates a new branch. Use jj branch create
instead.
jj init --git in an existing Git repository now errors and exits rather than
creating a second Git store.

jj workspace add can now take multiple --revision arguments, which will
create a new workspace with its working-copy commit on top of all the parents,
as if you had run jj new r1 r2 r3 ....
You can now set git.abandon-unreachable-commits = false to disable the
usual behavior where commits that became unreachable in the Git repo are
abandoned (#2504).
jj new gained a --no-edit option to prevent editing the newly created
commit. For example, jj new a b --no-edit -m Merge creates a merge commit
without affecting the working copy.
jj rebase now takes the flag --skip-empty, which doesn't copy over commits
that would become empty after a rebase.
There is a new jj util gc command for cleaning up the repository storage.
For now, it simply runs git gc on the backing Git repo (when using the Git
backend).

Fixed another file conflict resolution issue where jj status would disagree
with the actual file content.
#2654

Thanks to the people who made this release happen!
