latest Mountain Lion beta

Apple has seeded yet another OS X Mountain Lion 10.8.2 beta to registered developers. This release, which sports build number 12C50, is the fourth seed in under a month, and it indicates the software's public release is imminent. But unlike the other three, this one includes a number of new features.

It has that much-anticipated Facebook integration built-in, like previous 10.8.2 betas, but it also boasts Power Nap support for the late-2010 MacBook Air, the ability to receive iMessages sent to your iPhone's phone number, shared Reminders lists, Dictation support for a number of countries, and more.

Apple's release notes detail the complete list of changes and improvements:

Facebook

  • Single sign on for Facebook
  • Facebook as an option when shari
  • Share scores to Facebook, Twitter, Mail, or Messages
  • Facebook friends are included in Game Center friend recommendations
  • Facebook Like button for games
  • Challenge friends to beat your score or achievement

  • New sort options allow you to sort notes by title, the date you edited them, and when you created them
  • Dictation now supports Mandarin, Cantonese, Spanish, Korean, Canadian English, Canadian French, and Italian
  • The Dictionary application now includes a French definition dictionary
  • Sina Weibo profile photos can now be added to Contacts

The 10.8.2 update also includes general operating system fixes that improve the stability, compatibility and security of your Mac, including the following fixes:

  • An option to discard the changes in the original document when choosing Save As
  • Unsent drafts are opened automatically when launching Mail
  • Receive Twitter notifications for mentions and replies from anyone

The update is available now to registered developers via Apple's Dev Center. It's unclear when the release will make its public debut, but Apple is clearly working quickly to make that happen. We'd expect to see this update hitting the Mac App Store within the coming weeks — possibly alongside the new Macs that are rumored to be coming in October.
