I did a bit of search and found some new information about the Classic Editor and the new editor. It sounds like they are phasing in the new editor and we will receive emails as to those dates.
This paragraph caught my eye:
“There are exciting new features in the pipeline that require the new WordPress editor. It’s not technically possible to retrofit them into the older, Classic editor, and we want to make sure everyone can take advantage of them as they become available. With all WordPress.com users publishing with the Block editor, all WordPress.com users always have the latest and greatest.“
From the post:
“With the introduction of the Block editor, the WordPress.com Classic Editor was set for retirement at the beginning of June. We pushed that back a bit to make time for more changes that ease the transition to the Block editor — and now it’s time!

If you’d rather stick with the Classic editor experience — the one you used before we introduced the WordPress.com editor a few years ago — no worries. With the new and improved Classic block, you have the best of both editors: the flexibility and stability of the Block editor, and the Classic editor interface, you know.
