No firm date that I've heard. They've never announced those in advance. But the prerelease is live, and a second beta is due any day/week. It seems the final release will be in coming weeks or months. More on the news of the prerelease so far in a post I just offered last night:

Also, FWIW, as for the coming eol for cf2021, I have a post written for that which I was going to post later this morning. Wanted to get that cf2025 post out first. :-)
