Although still in planning stage, what we know for sure is that it'll be based on QtWebKit-2.1 (the branch has been forked from the qtwebkit-2.1 branch) and should be made available sooner than usual (in terms of branch stabilization time).
Please note that, just as QtWebKit-2.1, QtWebKit-2.2 will be an intermediary release, non officially supported by Nokia on all platforms.
Some links of interest:
- QtWebKit-2.2 wiki page
- Tracker for QtWebKit-2.2 critical bugs
- Tracker for QtWebKit-2.2 non-critical bugs
- QtWebKit-2.2 branch on gitorious
Tests and feedback are very welcome, as usual.
