Apple released the latest version of the Mountain Lion developer preview on Friday, and it has two interesting new features – Twitter notifications and browser tab sync. These additions are the latest in Apple’s crusade to bring good ideas from mobile devices over to OS X.

Twitter notifications appear in the OS X notification center, which is itself a new feature added in the previous Mountain Lion developer preview. Once you’ve entered your account details it works exactly like a Twitter app installed on an iOS or Android device. In addition, entering your Twitter login makes that data available to other installed apps via a developer API.

The other big addition is tab syncing for Safari, which comes courtesy of a new iCloud logo hanging out beside the address bar. Clicking on this will make the tab available in Safari on all iCloud connected devices you own. It will also be possible to open tabs from other devices on your OS X machine, as well. This should eliminate any feelings of jealously Mac fans had about Chrome for Android.

Last, but not least, is a new contact security prompt. Whenever an app installed on OS X tries to access your contact data you will be shown a prompt that allows you to allow or deny it. You’ll also be able to see the apps that have been given permission in the security section of system preferences.

What do you think of these changes? Are you happy about them, or is there starting to be too much iOS in your OS X?
