Clarification on the recent Bitcoin Core change:

The OP_RETURN size limit was not removed.

What changed: transactions can now include multiple OP_RETURN outputs, each still limited to 80 bytes.

Example:

Previously → 1 OP_RETURN (80 bytes max)

Now → 3 OP_RETURN outputs (80 bytes each, same total size rules)

This is not a removal of limits just more flexibility within them.
