Jeremy's current plans for X.Org Server 1.9.1 have the first release candidate coming on 12 November, a second release candidate on 3 December, and then either an RC3 or final release on 10 December.
This news was announced by Huddleston on xorg-devel.
On a related note, it's been decided by the X.Org Board of Directors to participate in Google's Code-In program, which provides students between the ages of 13 and 18 years old various open-source work to participate in during their winter holiday. X.Org has long participated in Google's Summer of Code, which is a much bigger program and runs the duration of the summer holiday, but the Google Code In is designed for smaller tasks.
On this X Wiki page are a few ideas for any able students interested in participating. Among the ideas are small code tasks like adding X-Video attributes to GNOME/KDE display applets, support for more RandR output attributes in GNOME/KDE display applets, and exporting KMS connector attributes via sysfs. There's also non-code work like improving the documentation, helping out with the testing process, and research.
