- Add new webkit_glue VisitedLinkHash() and IsLinkVisited() functions required by underlying chromium changes.
cefclient:
- Add sample netscape-style plugin implementation and related Plugin item on the Tests menu.
- Increase the speed of the update timer so that buttons refresh closer to real-time.
