Migration to new class names was not reported in the Changelog.

Hello

We just updated from 5.0 to 5.1. We had some issues finding the required changes to class names as they are not reported in the release. We specifically had problems with finding the move from PieEnrty to PieEntryFloat.

It might be good to add a list of class name changes on the release, or at least a clear indication about the API changing for the release. Maybe for similar changes that change the library's API to be listed as major version bumps in the future.

Thanks for the great work keeping this library alive and up-to-date!

Looking at the release again, I see a link to the breaking changes. It might still be good for them to be more clearly stated.

Thanks a lot again!

Ok, I made #766 and updated the release note, but I'm not full convinced if this solves now the not-finding-breaking changes.
An other way would be to keep old legacy classes and mark them as deprecated. But even here, some guys will not keep an eye on it

For you it's too late, but I made a new version which helps to migrate, containing #767
