Apple shared all the new goodies coming to its desktop operating system today at WWDC.

First, OS X is moving to a new naming path. Apple's SVP of software Craig Federighi, who demonstrated the latest OS upgrade on stage, announced that the new versions of OS X will be named after places in California. This new version will be named Mavericks, after the famous Northern California big-wave surf spot. So goodbye kitties, hello ocean.

Mavericks will be made available to developers this week, and it will be released to consumers in the fall.

Apple is addressing workflows, security and browsing with this newest update. The latest features:

Finder Tabs: You can pull all your windows into a single tab. Each tab has its own location and its own view mode.

Tagging: When you save a document, you can tag it. It'll appear right in the Finder side bar. You can tag it wherever it is in the Finder. This looks like it will be great for search.

Multiple Displays: When you go full-screen on one display, it doesn't mess up your other display. This means you can have different apps running in full-screen mode. The menu bars are also now accessible on both displays. When you pan between spaces, you can do it independently on each display.

Compressed Memory: When you’re running an app, a subset of your system memory is inactive. With this new feature, you can compress inactive memory to make free space available almost instantaneously to the application. Apple claims it provides 1.4x the responsiveness under load than Mountain Lion, and 1.5x improvement in waking the system from standby.

App Nap: This feature gives direct power to only apps that need it right now. If something is in the background or inactive, it doesn't soak up processor resources.

Safari: There's an under-the-hood overhaul to the browser. There are JavaScript and memory improvements, and Apple says Safari now uses less memory than other browsers. One cool thing in the WWDC demo was the improved scrolling engine – it's super-smooth. The browser's rendering engine has also been optimized for Retina displays. Safari has a new sidebar. The most interesting addition is the Shared Links tool, which show all the links your friends are dropping in Twitter and LinkedIn (no Facebook yet). You can scroll through those sidebar links on the left, and see the pages flip by on the right. Bookmarks work the same way, with smooth-scrolling between pages. Also impressive is the updated Reader mode, which strips out most of the page treatments and just shows text and key images in a more readable format. Scrolling between articles is continuous, and super-smooth.

iCloud Keychain: It's just like 1Password for the Mac.

Notifications: You can now reply or respond right inside a notification. Apps that push notifications on your iOS device can now be pushed to OS X. When you wake, it'll tell you everything you've missed on your Lock Screen, just like on your iOS device.

Calendar: Click on a calendar event, and the new inspector shows much more information. It's aware of location, travel time and weather.

Maps: Apple Maps from iOS comes to the Mac desktop (Uh oh!). You can send routes from OS X to iOS. Any route you send to your phone will appear directly on your lock screen. Unlock the phone, go directly to the route and get your directions. There will be a developer SDK for desktop Maps.

iBooks: It's also coming to the Mac, so you can read your purchased books on any OS X or iOS device now. Oh, and there's no weird stitching in the app anymore.

Of course, all these specs and speed estimates come from Apple, and our impressions are based on what we saw happening on stage. The scrolling does look super, super slick, but of course, we'll only see how these new features perform in the real world when Mavericks lands in the fall.
