An updated Core, with Ragnarök and CSS3 radial gradients

October 7th, 2011

We have a rather interesting new snapshot for you today. It includes an update to our Core rendering engine (Presto) to version 2.9.220, and with that come some really big improvements.

Firstly, this is the first snapshot to include Ragnarök! For those of you who haven't tested our earlier Labs builds, Ragnarök is the name of our implementation of the HTML5 Parsing algorithm. As Bruce Lawson explained previously, "The HTML5 specification defines a set of parsing rules for all markup, whether valid or invalid. Once all browsers have HTML5 parsers, the same markup will produce the same DOM across all conforming browsers.". :headbang: If you would like to know more, you should also read our initial announcement, from the first Labs release.

Another big one among other Core changes is that we have improved our CSS3 gradient support. We already supported CSS3 linear gradients and now we have added support for CSS3 radial gradients.

Besides these major improvements, the Core team have also done a lot of site compatibility work. Together these Core updates should mean that Opera renders your favorite sites better than ever! :yes:

Finally, we also have a nice selection of important desktop improvements (I personally like the new on-demand plug-in activation) and bug fixes. As always, see the change log below for a full overview. And once you are done with that, download and get on with testing!

Known issues
