release notes

### Note to packagers

jj now links libgit2 statically by default. To use dynamic linking, you

need to set the environment variable LIBGIT2_NO_VENDOR=1 while compiling.

(#4163)

Breaking changes


jj rebase --skip-empty has been renamed to jj rebase --skip-emptied


jj backout --revision has been renamed to jj backout --revisions.

The short alias -r is still supported.


The default immutable_heads() set

now includes untracked_remote_branches() with the assumption that untracked

branches aren't managed by you. Therefore, untracked branches are no longer

displayed in jj log by default.


Updated defaults for graph node symbol templates templates.log_node and

templates.op_log_node.


The "fileset" language is now enabled by default. It can

still be disable by setting ui.allow-filesets=false.


On jj git fetch/import, commits referred to by HEAD@git are no longer

preserved. If a checked-out named branch gets deleted locally or remotely, the

corresponding commits will be abandoned.


jj --at-op=@ no longer merges concurrent operations if explicitly specified.


jj obslog -p no longer shows diffs at non-partial squash operations.

Previously, it showed the same diffs as the second predecessor.


Deprecations

The original configuration syntax for jj fix is now deprecated in favor of

one that allows defining multiple tools that can affect different filesets.

These can be used in combination for now. See jj help fix for details.

New features


External diff tools can now be configured to invoke the tool on each file

individually instead of being passed a directory by setting

merge-tools.$TOOL.diff-invocation-mode="file-by-file" in config.toml.


In git diffs, word-level hunks are now highlighted with underline. See diff

colors and styles for customization.


New .diff().<format>() commit template methods are added. They can be used

in order to show diffs conditionally. For example,

if(current_working_copy, diff.summary()).


jj git clone and jj git init with an existing git repository adds the

default branch of the remote as repository settings for

revset-aliases."trunk()".`


jj workspace forget now abandons the workspace's working-copy commit if it

was empty.


jj backout now includes the backed out commit's subject in the new commit

message.


jj backout can now back out multiple commits at once.


jj git clone some/nested/path now creates the full directory tree for

nested destination paths if they don't exist.


String patterns now support case‐insensitive matching by suffixing any

pattern kind with -i. mine() uses case‐insensitive matching on your email

address unconditionally. Only ASCII case folding is currently implemented,

but this will likely change in the future.


String patterns now support regex:"pattern".


New tracked_remote_branches() and untracked_remote_branches() revset

functions can be used to select tracked/untracked remote branches.


The file() revset function now accepts fileset as argument.


New diff_contains() revset function can be used to search diffs.


New command jj operation diff that can compare changes made between two

operations.


New command jj operation show that can show the changes made in a single

operation.


New config setting git.private-commits to prevent commits from being pushed.


The default commit description template

can now be configured by templates.draft_commit_description.


jj fix can now be configured to run different tools on different filesets.

This simplifies the use case of configuring code formatters for specific file

types. See jj help fix for details.


Added revset functions author_date and committer_date.


jj describe can now update the description of multiple commits.


Fixed bugs


jj status will show different messages in a conflicted tree, depending

on the state of the working commit. In particular, if a child commit fixes

a conflict in the parent, this will be reflected in the hint provided

by jj status


jj diff --git no longer shows the contents of binary files.


Windows binaries no longer require vcruntime140.dll to be installed

(normally through Visual Studio.)


On quit, the builtin pager no longer waits for all outputs to be discarded.


jj branch rename no longer shows a warning in colocated repos.
