The Krita VCS plugin (aka Krita VC)
A small Version Control panel that lives right inside Krita, so you can save a version, set work aside, or switch branches without ever leaving your canvas. It runs on the exact same engine and the exact same history as the desktop app. Save from either one, and the other sees it.

Tracking your color palettes too
Color palettes (.gpl, .kpl, .aco, .ase) sitting next to your art get tracked too, right alongside the .kra file. Untick them if you'd rather leave them out of a version.
