release notes

### Breaking changes


Dropped support for ui.default-revset config (replaced by revsets.log in

0.8.0).


The commit_summary_no_branches template is superseded by

templates.branch_list.


jj split will now refuse to split an empty commit.


jj config list now uses multi-line strings and single-quoted strings in the

output when appropriate.


jj config get/list/set now parse name argument as TOML

key. Quote meta characters as needed.

Example: jj config get "revset-aliases.'trunk()'"


When updating the working copy away from an empty and undescribed commit, it

is now abandoned even if it is a merge commit.


If a new working-copy commit is created because the old one was abandoned, and

the old commit was merge, then the new commit will now also be.

#2859


jj new's --insert-before/--insert-after options must now be set for each

commit the new commit will be inserted before/after. Previously, those options

were global flags and specifying them once would insert the new commit before/

after all the specified commits.


Deprecations

Attempting to alias a built-in command now gives a warning, rather than being

silently ignored.

New features


jj branch list/tag list now accept -T/--template option. The tag list

prints commit summary along with the tag name by default.


Conflict markers now include an explanation of what each part of the conflict

represents.


ui.color = "debug" prints active labels alongside the regular colored output.


jj branch track now show conflicts if there are some.


A new revset reachable(srcs, domain) will return all commits that are

reachable from srcs within domain.


There are now prebuilt binaries for aarch64-linux-unknown-musl.

Note, these are cross compiled and currently untested.

We plan on providing fully tested builds later once our CI system allows it.


Added new revsets mutable() and immutable().


Upgraded scm-record from v0.2.0 to v0.3.0. See release notes at

https://github.com/arxanas/scm-record/releases/tag/v0.3.0


New command jj fix that can be configured to update commits by running code

formatters (or similar tools) on changed files. The configuration schema and

flags are minimal for now, with a number of improvements planned (for example,

#3800 and

#3801).


jj new's --insert-before and --insert-after options can now be used

simultaneously.


jj git push now can push commits with empty descriptions with the

--allow-empty-description flag


Fixed bugs


Previously, jj git push only made sure that the branch is in the expected

location on the remote server when pushing a branch forward (as opposed to

sideways or backwards). Now, jj git push makes a safety check in all cases

and fails whenever jj git fetch would have introduced a conflict.
In other words, previously branches that moved sideways or backward were

pushed similarly to Git's git push --force; now they have protections

similar to git push --force-with-lease (though not identical to it, to match

the behavior of jj git fetch). Note also that because of the way jj git fetch works, jj does not suffer from the same problems as Git's git push --force-with-lease in situations when git fetch is run in the background.


When the working copy commit becomes immutable, a new one is automatically created

on top of it to avoid letting the user edit the immutable one.


jj config list now properly escapes TOML keys (#1322).


Files with conflicts are now checked out as executable if all sides of the

conflict are executable.


The progress bar (visible when using e.g. jj git clone) clears the

remainder of the cursor row after drawing rather than clearing the entire row

before drawing, eliminating the "flicker" effect seen on some terminals.
