This has one change to the way the Link field type works. You can now specify a default prefix for a Link field, which means you don’t have to enter the prefix when entering a value, and don’t have to look at the prefix when the value is displayed. I’m using this for Wikipedia links, but perhaps it might be useful in other cases as well?
Anyway, the Link field has lots of special logic, so beta testing would be good to make sure I haven’t broken anything else!
Sorry, found a bug in this beta, and also am rethinking my approach here.
