I've passively maintained this crate for the libc CI, but it doesn't use it anymore and this crate now has some issues as below:

• this crate depends on the save-analysis feature, which is planned to remove in the near future
• this crate doesn't work nicely on some code

Both need some hard work (in particular, the former would need to do rearchitecting), but I'm afraid that I don't have time to do it currently for other projects' maintenance.
Because there are now some alternatives in the community, like https://github.com/obi1kenobi/cargo-semver-checks or https://github.com/Enselic/cargo-public-api, I think it's time to deprecate this crate.

@ibabushkin @Xanewok Any thoughts on this?
