+The Xen hypervisor project now releases every 8 months. The actual release date
+depends on a lot of factors.
We can roughly divide one release into two periods. The development period
-and the freeze period. The former is 4 months long and the latter is about 2
+and the freeze period. The former is 6 months long and the latter is about 2
months long.
During development period, contributors submit patches to be reviewed and

-
-* Development period: 2017 June 11 - 2017 September 29
- * the "cut-off date" is 2017 September 29
- * the "last posting date" is 2017 September 15
-* Freeze period: 2017 October 2 - 2017 December 7
