What’s new in Git 2.45.0?

What this post added

Introduced the 'reftable' backend in Git v2.45.0, a new binary format for storing references that addresses scalability issues, atomic read/write limitations, and housekeeping inefficiencies of the traditional 'files' format. This project was led by Patrick Steinhardt, with contributions from Shawn Pearce (original inventor) and Han-Wen Nienhuys (reftable library author). Also contributed to tooling improvements: `git-for-each-ref --include-root-refs` for listing all references (led by Karthik Nayak) and `git-reflog list` for listing all reflogs (led by Patrick Steinhardt). Introduced `git pack-refs --auto` mode for more efficient packing of references, particularly for the 'reftable' backend (led by Patrick Steinhardt).
