There's a big debate about it in Technical Discussion as achow101 mentioned.
Some short videos from Matthew Kratter to get you up to speed on the matter more quickly:
From discussions I have read elsewhere, none of the videos he has posted are actually accurate and supposedly he is significantly overexaggerating/being hyperbolic. I cannot attest this as I have not watched them myself.
the announcement was made a couple days ago by the devs and the PR will be merged. We will see.
There is no such announcement that anything will happen. I would happen to know, as I am one of the maintainers.
The document that was published a few days ago was a draft of one that had intended to be "official" from the project, but it did not have enough agreement amongst contributors to adopt it as such. The author then published the draft. It is neither an announcement nor the project's "official" stance on the topic.
Regardless, continued discussion of OP_RETURN limits is off topic for this thread and I will be removing any further posts on the subject. Go to the myriad of other threads/forums where this is being discussed.
Thank you for the info. It is a relief to hear that. I am hearing a lot of conflicting information right now.
Some articles came out yesterday claiming otherwise so I don't know what to believe. Of course they could be wrong.
It appears they are using comments on Github as the source but that probably doesn't qualify as an official announcement.
I guess the only way to know for sure is when the next release of Core comes out.
