Happy to announce that BinkyLabs #overlays 3.0 just dropped!
It supports #OpenAPI Overlays 1.2 with reusable actions which greatly improves the authoring experience of large Overlay documents.
This library and associated CLI were used to help mature the specification updates as well. Open-source standards at work!
