Just a quick update to tell you beta 2 of QtWebKit 2.3 has been tagged. I am planning to tag the release before the end of the month.
I would like to already now thank for all the encouragement and backup I have received on the project, Qupzilla and rekonq developers have been very helpfully and are already recommending to use QtWebKit 2.3 beta together with their applications, and a handfull of linux distros have been packaging it. The only thing missing is more feedback from Mac or Windows developers. On Linux this beta could be considered release quality, but on Mac and Win, there are still some issues I hope can get ironed out soon.
Fixed in beta 2:
