The latest version of the Opera browser was released a few days ago. Opera 10 finally implements a few features that were noticeably missing from the previous version, specifically in the realm of CSS3. Rather than failing miserably at implementing RGBA (Opera 9 just ignored anything with RGBA colors specified, making it completely transparent instead of making it opaque as the CSS spec indicates). The implementation of CSS3 selectors has also been improved. Opera 10 also apparently allows Web developers to declare a source for the font-face property in their style sheets.

The border-radius (rounded corners) property is still not implemented, so you’ll have to continue viewing things in Mozilla-based (Firefox) or Webkit-based (Safari, Konqueror, Chrome, etc.) browsers if you want to see the border-radius property in action.

According to the changelog for Opera 10, the new version got a perfect score in the ACID3 compliance test, adds a bit of HTML5 support and allows you to use SVG fonts.

I haven’t used Opera 10 too much, but I am curious to see how its speed stacks up against Chrome, Safari and even IE8 and I’m very curious to see how it’s development tools stack up against the Firefox add-ons I have installed.

As a side note, I am happy to see that Opera provides resources, such as logos, for press and bloggers. It’s become increasingly difficult over the last few years to find that type of information on corporate Web sites.
