Opera ports its WebGL hardware acceleration from Opera Mobile to the Android version of Opera Mini 7, which first debuted last month at Mobile World Congress in Barcelona, Spain.

Opera Mini 7 for Android (download) improves the lightweight browser's compressed browsing feature called Turbo with hardware acceleration, and expands the Speed Dial landing page beyond nine Web sites.

It does not include the new home screen that is coming to Opera Mini 7 for feature phones, which will bring interactive social-networking to people who have those lower-powered phones.

Phillip Gronvold, Opera's product manager for mobile, told CNET before the Barcelona event that Opera Mini's data-compressing Turbo makes the browser an important option for people on plans with tight data restrictions. He also said that Turbo works a bit differently on different versions of Opera, with Turbo willing to sacrifice Web site stability for its enormous bandwidth savings -- up to 90 percent less data in some cases.

Meanwhile, development proceeds on Opera 12. HTML5 Drag and Drop is now supported, which allows for dragging items between Web sites, or to and from the desktop. CSS3 Animations has been added to Opera 12, and support for CSS3 Transitions has been improved.

Out-of-Process Plugins have also been added to this rough developer's build of the browser. OOPP, which has been available in Chrome and Firefox for some time, prevents plug-in crashes from crashing the entire browser. Opera stated in its blog post announcing the update that it expects OOPP to also allow for 32-bit plug-ins to run in a 64-bit browser, although it didn't clarify how that would be achieved.

Finally, Mac installers of Opera will be universal going forward. This means that they will automatically default to 64-bit, unless you're running a 32-bit Mac. The company will no longer produce a stand-alone 32-bit version for Macs, probably because new Macs all have been 64-bit for a few years.
