As you may know, the BlackBerry PlayBook browser ranks first among all native tablet browsers in the HTML5 test. We’ve pushed a new playbook-2.0.0 branch to our WebKit-PlayBook repository in GitHub. This branch contains the WebKit source code in the PlayBook 2.0 (b.7971) release.
We are also in the process of integrating the QNX port into the subversion repository at WebKit.org. You can follow our latest development at WebKit.org.
