Hey. There's a new kid around the block, bzip3: https://github.com/kspalaiologos/bzip3
With quite impressive results, see for example a test I've made here: https://github.com/digint/btrbk/pull/501#issue-1449056394 It’s as good (or at least in some cases actually better) than xz, but way faster. Would be quite nice if zutils could support that. Thanks, Chris.
