Jujutsu v0.41.0 release notes

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

jj fix now supports formatting specific line ranges (allowing you to format only modified lines); see the configuration manual and notes below for more.
The new global flag --no-integrate-operation will let you run a command without impacting the repo state or the working copy, which is useful when automated tools may create snapshots in the background.

The --pattern flag for file search now defaults to regex: instead of glob:.
jj git push --all/--tracked/-r REVSETS no longer fails when revisions to push are private or have conflicts. Bookmarks which aren't eligible to push will be skipped.
Branch/bookmark patterns passed to jj git clone are now saved to jj's repo settings file instead of .git/config. Git fetch refspecs are set to the default value.

In the templating language, the Operation type's .tags() function has been deprecated in favor of .attributes().

The --pattern flag for file search now accepts various pattern kinds through kind:pattern syntax.
A new global flag --no-integrate-operation lets you run a command without impacting the repo state or the working copy.
A new config option diff.git.show-path-prefix can be used to suppress the a/ and b/ path prefixes in the diff --git output.
jj fix now supports line range-limited formatting via the fix.tools.<name>.line-range-arg and run-tool-if-zero-line-ranges configs. This allows running tools only on modified lines and fine-grained control over when the tool is run. If you have set the line-range-arg config, use --all-lines to match the previous behavior of formatting the entire file.
A new replace(pattern, content, replacement) template function is added which supports replacement of content in templates, using a lambda to format replacement text. It supports all string patterns, including regexes with capture groups (e.g. replace(regex:'(\w+) (\w+)', "hello world", |c| c.get(1) ++ " " ++ c.get(2))).
New ByteString template type for things like file content.
jj gerrit upload now supports the new options --message (-m), --edit and --merged. You can now also pass multiple hashtags by repeating the --hashtag option.
New remotes.<name>.fetch-bookmarks/fetch-tags options to configure default fetch targets.
JJ_PAGER can now override the ui.pager config, matching JJ_EDITOR for callers that need a jj-specific environment override.

Improving consistency with git handling of .gitignore, including / after entries and \r\r\n for MacOS files.
jj status filters untracked paths by fileset #9287
Improved performance for snapshotting, visibly improving jj status speed for large repositories.
Pre-existing Git submodule directories are no longer considered conflicts in checkouts. #8065.
Fixed a panic in jj gerrit upload when run without -r and the inferred revision was immutable. #9398
jj status respects path filters in working copy summaries.
jj git remote rename/remove now updates the trunk() alias.
Commands would sometimes incorrectly diagnose a stale working copy and suggest running jj op integrate when it would have no effect. This should now be much less likely to happen in practice. #9314

Thanks to the people who made this release happen!
