Just updated my pin crate. I wouldn't post about it, except I learned something. When I initially built & published the crate, I specified a dependency on clap, with a version of "3.0.0-beta.1".

Last autumn, the clap project released "3.0.0-beta.2" which broke my crate. It turns out that when you say "x.y.z" in your Cargo.toml, you are specifying a caret dependency to cargo, and it will, on its own book, upgrade you if it thinks it's safe to do so (according to the rules of semver).

Pre-releases are covered under semver here; cargo evidently decided that since I had (implictly) indicated a willingness to be upgraded, beta.2 would do as well as beta.1. I suppose I'm to blame for pulling in a beta release (which contained breaking changes).

Regardless, I've now specified my dependency on clap as "=3.0.0-beta.2", meaning give me this version, damnit.
