Git 2.45 was released on April 29, 2024, adding preliminary support for the reftable reference-storage backend, experimental SHA-1 to SHA-256 interoperability, and quality-of-life improvements like a cherry-pick --empty option. Here is what changed.

Git 2.42 was released on August 21, 2023, adding a faster boundary-based object traversal, reference jump lists that speed up excluding references during pushes, and a new hook to preserve precious unreachable objects from garbage collection. Here is what changed.
