I always try to release a new version of my plugins as close as possible to the first EAP, but I believe removing the until field is a bad decision.
If I don’t make it in time for the EAP, those brave developers who upgrade early will face breaking compatibility issues unless I go through all my previous releases on the Marketplace and manually add until build constraints until I can fix them. With four plugins and a full-time job, this isn’t something I can do quickly.
Since I personally use the latest EAP builds myself, I know firsthand how frustrating it can be when plugins break. I’ll have to think twice before updating because I’ll run into issues from all plugins that haven’t been updated yet.
The more advance notice we have about upcoming releases, the easier it is for us to prepare. Still, I really hope you’ll reconsider removing the until field.
