Hi,
If you looked at the previous trend there is never official communication about product GA dates in advance & until and unless product is released there won't be any fix notes as well.
You may receive tentative dates once the Beta is out.
As of now I don't have any info about it.
You can subscribe to receive notification when a new product is released.
