I've updated Block Designer to version 1.2.3, now my field types from Block Designer Pro are not showing, what to do?
Just install the latest version of Block Designer Pro. Version 1.2.3 of Block Designer had some changes to namespaces, to make it compatible for OSX. If you're not on the latest Pro version, those files will not be loaded. Just update and you're good to go!

What versions of concrete5 are compatible?
This works with version 5.7.x and 8.x.x. So no worries that this will break in upcoming concrete5 versions, we will get you up and running before any (big) stable release.
