About the versioning, glad you spotted it anyway. There isn't as much use of the gzhttp package compared to the other ones, so the bar is a bit higher for that one.

Also making good progress on getting a slimmer version of zstd into the stdlib and improving the stdlib deflate.

Yeah, I make it a habit to read the changelogs of every update to every direct dependency. I was anticipating this change for years, thanks for doing it!
