This next milestone is a code freeze for X Server 1.7 and will mark the first beta release of X.Org 7.5. However, with this code not even been branched yet from master, do you think this next milestone will be on time with the 20th of July? A month from tomorrow is when the official release of X.Org 7.5 is scheduled to be. Had the earlier release schedule been met, X.Org 7.5 with X Server 1.7 would have been released yesterday.
As of yet, there is no official communication whether X.Org 7.5 is being delayed or not, which leaves some distribution vendors and others in the dark. The X.Org developers (many of whom are unpaid) are doing a great job evolving this critical part of the Linux desktop, but the ever-changing release schedules and lack of communication at times is certainly an area that can be improved. Hopefully though X.Org 7.5 will still make it out well in time for the Q3'09 round of distribution updates.
