Git 2.55 slashes repo maintenance with incremental MIDX repack and adds history‑fixup
Git 2.55 adds an incremental multi‑pack index repack mode, letting you append new MIDX layers without rewriting the whole index—cutting maintenance time for massive repos. It also introduces a history‑fixup command that moves staged changes into earlier commits, streamlining interactive rebasing. Both features shrink downtime and simplify repo hygiene.
