0.4.5 breaks API over 0.4.2
I have a project built against 0.4.2 which suddenly stopped working with compiler errors.
cargo is free to upgrade between "patch" versions, like from 0.4.2 to 0.4.5 as patch versions are not allowed to change the API. Some changes from 0.4.2 to 0.4.5 introduced API changes and should have come with an increase in the minor version number, e.g. "0.5.0".
It is too late for this now, but would be great for the future to only do API changes only via minor version number increase. More info here: https://semver.org
Workaround is to pin the version using "=0.4.2", but this is generally considered bad practice.
We should add https://github.com/obi1kenobi/cargo-semver-checks to CI so we're more aware of this kind of breakage in the future and so that we can describe API changes up front in the changelog with minimal effort.
Totally agree. Let's add that to the CI and close this issue when we make a new major release.
@Danvil , thank you for reporting this. We have added semver checks to our CI and hopefully this won't happen again in the future. There is a new major release as of today, so I am closing this.
