We have a managed package currently using custom settings, and it has been installed in all editions except Database.com, i.e. Group, Professional, Performance, Unlimited and of course Developer.
We are interested in using custom metadata types to store some application configuration details, but according to this, custom metadata types are not available in Group edition.
Therefore, if I package custom metadata types with the managed package, will it prevent Group edition owners from upgrading or installing the package?
Also, I just created an Partner Group edition, and I can actually see the Custom Metadata Types menu in the setup? Could it be that the documentation is out of date?
