Hello Vaijanath, thank you for your reply.
I noticed now, in the third link you provide, under the milestones sections of version 2.7 and 2.8. They specify an end of sale date, why they did that, they don't mention it, in the the 2 first links you provided?
I don't know why they didn't mention end of sale date on first and second link. But they did mention it it in the third link.
