Apple Mac OS X 10.8 Mountain Lion includes lots of features from iOS, such as Reminders, Messages and Game Center. One noted update from the previous version of the Developer Preview is a Do Not Disturb setting to Mountain Lion’s Notifications Center, as outlined by 9to5mac, which allows users to block incoming alerts and banners.
Furthermore Mac OSX 10.7.4 Lion Update is around the corner: 11E53 is the current build that was seeded to developers. The previous release was numbered 11E52 – so a final public update is imminent. Apple notes that there are no known issues with this build but asks developers to focus their testing on graphics, iCal, Mail, Printing, and Time Machine.
If there are updated kexts is not known at the time of writing – it looks like we have to wait for the final release of 10.8 ML to get new graphics drivers, such as support for the 7xxx AMD Radeon GPUs with the Codenames Cedar, Caicos, Turks, Cape Verde, Pitcairn, Tahiti and New Zealand.
