You should have bumped to 0.5 when you made the change that caused Alex-PK/chrono-locale#5

FYI. Patched by Alex-PK/chrono-locale#6 but @Alex-PK hasn't merged anything since 2018 so maybe you want to review this.

Hmm, that's a tricky one. There's an Internal variant that tries to make it clear that this is intended to be non-exhaustive, but clearly it's not entirely effective. Given that this hasn't been much of an issue, I don't think we're going to go back and fix the semver issue here now. We should start by making some types explicitly non-exhaustive now that we've bumped the MSRV on main.

Are you aware with the built-in localization support that chrono offers?

Well, it broke one of my font editor's core libraries, ipc.rlib. From its name, you can assume that that library is included in every binary in the MFEK org pretty much.

Regarding unstable-locales, no, was not aware of it, and ipc.rlib far predates it. But I can look into changing to it when it's stabilized, my patch Alex-PK/chrono-locale#6 fixes the problem for me and the MFEK org can just maintain that library for as long as it takes to stabilize.

I don't think there is anything that can be done by now, removing the enum variants after 4 releases would also be a breaking change.
