Release Notes

jj-vcs/jj (jj-lib)

v0.45.1

Compare Source

This release fixes an error that prevented the new jj-core crate from being
published.

Fixed bugs

• Building without Cargo.lock (e.g. cargo install jj-cli) works again
  after all versions of the bisync crate, a transitive dependency of gix,
  were yanked.

• Signatures on commits in SHA-256 Git repositories are now stored under the
  gpgsig-sha256 header, as Git does, so Git recognizes them as signed and
  jj can read them back.
