About
jj is a Git-compatible version control system that is both simple and powerful. See
the installation instructions to get started.
Release highlights
jj runallows 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-featuresorjj run -- cargo fixbehaves as one might expect.
Breaking changes
-
The deprecated
git_head()andgit_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-defaultoption has been removed. -
jj bookmark track/untrackno longer supports<kind>:<bookmark>@<remote>
patterns. However, the<bookmark>@<remote>symbol syntax is still supported.
#9226
Deprecations
New features
-
jj shownow supports--reversedflag. -
jjnow looks for config files in/etc/jj. -
jj config gcwill delete configuration of deleted/moved repos from
~/.config/jj/reposfolder.
#9362 -
jj runallows 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-featuresorjj run -- cargo fixbehaves as one might expect. -
jj gerrit uploadnow supports the-o(--option) flag, which works like
git push -o(--push-option). -
jj git fetchnow 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. -
colorsconfig now supports crossed-out text styling with
{ crossed-out = true }.
Fixed bugs
-
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.gitand.jjdirectories.
#8924 -
jjnow 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 addnow 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 thoughgit fsckwould
later fail withincorrect data check,corrupt loose object, ormissing blob, and later jj operations could fail withcorrupt deflate stream.
