opam 2.4 was branched last week… very pleasing to see Ryan’s work on Nix depext support get merged (we spent quite a bit of time on that together last summer). It’s a subtle-sounding (huge) change, but the move away from relying on patch and diff as external commands (which has been a HUGE amount of work done by @kit-ty-kate) paves the way for being able to sort out the incredible slowness of opam update on Windows.

Not at all coincidentally, OCaml 5.4 was frozen two days ago as well. Relocatable OCaml not quite ready in time, but at least those PRs will be ready really, really[, really] soon 🫣…
