We're not actively working on new features for OmniWeb 6 at the moment, but we're certainly still continuing to develop and enhance OmniWeb 5. Check the long list of release notes for the
OmniWeb 5.10.2 release, which we shipped a few months ago—and don't forget to also check out the
sneaky peeks of our upcoming 5.11 release, which integrates the latest shipping WebKit from Safari 5.0.3 (along with a few other changes which might not have made it into the release notes yet, like adding "iPad 4.2.1" as an option in the "identify as" popup).
