By Adrian Perez de Castro. In the session we will talk about WebKitGTK+ new release and plans. The new WebKit2 API is going to be stable very soon, we will explain the differences, new additions and current situation of the API in more detail and we will show how to embed and use the new widget. We also will explain the multiple features we have added in the last year (accelerated compositing, gstreamer 1.0, networking, etc.) and the roadmap for the next year. Also as usual we will add nice demos. The talk should be interesting for embedders because new WebKit2GTK+ API should be used in the near future.

10. So… How's WebKit2GTK+ doing?
The evil is in the details
Doing nicely:

- Context menus
- Web inspector
- Favicons
- On-disk cache
- Spell checking
- Printing support
- Documentation, GI annotations…
