As usual, Apple’s World Wide Developers Conference (WWDC) brought changes to the tech world on Monday.

First to be introduced was “OS X Mavericks,” an update from the current “OS X Mountain Lion.”

Mavericks’ main objective is to maintain laptops’ and desktops’ battery life for a longer period of time. It also has all sorts of new gadgets and features. Maps, app notifications and iBooks, which were all previously only available on mobile devices will be a part of Mavericks.

Also announced was ”iTunes Radio” service. The service generates general and personalized radio stations based on music on a user’s iPhone.

New MacBook Pros, iMacs and MacBook Airs were also shown. The new computers promise longer battery life and enhanced features as well all available today.

The biggest part of the show was the introduction of iOS 7. It was described as “the biggest change to iOS since the introduction of the iPhone.” and it ”is like getting an entirely new phone, but one that you already know how to use, one that is so much more beautiful and functional than ever before.”

Features include the control center, part of quick settings feature, and easily turned features like Wi-Fi and Bluetooth on and off. iOS 7 will also multitask for all apps and basic functions of the phone, like iPhoto, will also be revamped.

OS X Mavericks and iOS 7 will be available in full in the fall.
