QupZilla seeks to provide native widget styles on major Linux desktop environments, a unified library for bookmarks/history/RSS, "speed dial" for accessing favorite web-pages, and other modern web functionality.
As mentioned in an official blog post last week entitled New QtWebKit and QupZilla, "QupZilla can now be compiled against Qt 5, so if you want, feel free to try it."
The latest QupZilla blog post largely talks about QtWebKit bringing in a recent WebKit version and that with this version WebGL is now working, there's support for spell-checking, a new Caret browsing option, an animated scrolling option, and a lot of fixes.
The blog post also notes QupZilla 1.4 is likely to be released in mid-February.
QupZilla was brought up in a recent Phoronix Forum discussion about the KDE Rekonq web-browser.
