According to the Opera Desktop Team blog, Opera 10.52 for Windows and Mac is officially out the door. However, the big story here is the Mac version, which has seen a complete re-design both on the outside and inside. The Linux version is not yet available.
Just 11 days after the release of the second beta, Opera has put the final touches on the Mac version of its web browser. According to their press release, Opera is calling 10.52 the "world"s fastest browser for Mac." Equipped with a completely new JavaScript engine, called Carakan, Opera 10.52 for Mac brings users multitouch trackpad support, Growl, HTML5 functionality, and a new Cocoa based interface.
CNet notes that the browser is compatible with older versions of Mac computers. This is something that competing browsers have been steering clear of. Even old school PowerPC machines can run Opera 10.52. You can view the changelog here.
