In reply to Nick.

Hey Javier, I don't know for sure but majority of end users use Gutenberg / Block Editor name interchangeably - as do Automattic - they often refer to it as "The Block Editor (Gutenberg). I'm betting on Nick is talking about the core updates. If he was talking about the plugin I'm pretty sure Chris from Extendify would have advised him of that anyway. The thing is new features sometimes come into Release Candidates for WordPress releases skipping alpha and beta testing, so with that it will make it difficult for add-on plugins I suppose.
This is my guess anyway.
