According to semver one should bump major version when introducing incompatible API changes.
#59 introduced breaking changes and thus broke others code.
Thanks!

I don't follow the recommendations of semver.

Thanks for what?

This is unfortunate, because that's what people expect: https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html

It would be nice if you could mention this fact in the readme, so users of the library could pin dependency to a specific version.

Thanks for you work on the useful package.

Useful package? Ahhhaaa. Nothing useful in it.

Don't worry about other users. No user has ever complained about bumping the major version.
