Git 2.45 is out today as an important step forward for this widely-used, open-source distributed version control system.

Git 2.45 is significant in this version having initial SHA1 and SHA256 interoperability for repositories. Git repositories with both SHA-1 and SHA-256 hash algorithm use can finally co-exist. Git has long been working on supporting the more secure SHA256 hashes rather than SHA1.

The other big aspect of Git 2.45 is having initial reftable support. Reftable is a new reference storage back-end for Git. Git's Reftable aims for faster performance with an entirely new format for storing Git references. With Git 2.45 new repositories can be initialized with the "--ref-format=reftable" argument for making use of it.
