Full Release Notes

### About

jj is a Git-compatible version control system that is both simple and powerful. See
the [installation instructions](https://docs.jj-vcs.dev/v0.45.1/install-and-setup/) to get started.

### Release highlights

This release fixes an error that prevented the new jj-core crate from being
published. See the [release notes for v0.45.0](https://github.com/jj-vcs/jj/releases/tag/v0.45.0) for more changes since v0.44.0.

### 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.
