Minimum Rust version changed in patch release

[wezm]

I'm not sure if you consider this a bug or not (people seem to have differing opinions on the interaction between changing minimum supported Rust version and semver) but I thought I'd point it out.

The 0.3.1 patch release introduced the use of #[non_exhaustive], which means it will now only compile on stable Rust 1.40.0.

Ahh, thanks for pointing this out, I remember noticing that addition but didn't reflect that it would change the minimum Rust version. I think in this case I'm going to publish a new patch without #[non_exhaustive] and yank the previous version, as that enum is only an input to this lib, and I would actually prefer people to get compile errors if they are for some reason matching on it in their own crates and it changes in the future.

Awesome, thank you.
