What this post added

This post details contributions to Git 2.51.0, specifically focusing on performance optimizations for `git-push` and `git-fetch` using batched reference updates, the transition of 'reftable' to be the default reference backend for new repositories, and the adoption of SHA-256 as the default hash function. It also notes the deprecation of `git-whatchanged` and the stabilization of `git switch` and `git restore`.
