If you are using Opera as your browser, then you’ll probably intersted to try Opera 10 (still in Alpha).
It gives a boost of performance increase, a perfect score for ACID 3 test (What is ACID 3?), Opera Mail improvements, and many more.
Opera 10 changes since 9.62 release:
Presto
Opera 10.0 includes the Presto 2.2 rendering engine. Detailed changes since Presto 2.1.1 are listed below:
Rendering

@font-faceat-rules; TrueType (TTF), OpenType (OTF), and SVG fonts are supported (demos) - Achieved 100/100 and pixel-perfect rendering on the Acid3 test
- Pretty-printing of unstyled XML (using unstyledxml.css in the Styles sub-directory of Opera’s installation directory)
- Added support for CSS3 RGBA color values (demo)
- Added support for CSS3 HSLA color values (demo)
- Added support for the CSS3
color: transparentvalue - Improved HTML5 support, including end-tag and start-tag parsing, whitespace parsing, and DOCTYPE parsing
- CSS files must be served with the correct MIME type (“text/css”) in Strict mode or they will be ignored
JavaScript/DOM
- New regular expression engine, which greatly improves performance on regular-expression-heavy pages such as the SunSpider JavaScript Benchmark
- Added support for the W3C Selectors API
- Renamed the objects returned by
getClientRects()andgetBoundingClientRect()toClientRectListandClientRectinstead ofTextRectangleandTextRectangleList, respectively XMLHttpRequestswill now trigger start-loading/end-loading events- Removed the proprietary

loadevent is now sent to frame/iframe/object elements before it is sent to the document - A highlight will no longer be added when
HTMLElement.focus()is called unless keyboard navigation is already activated

Thanks for the information, I have been waiting for this for a while now. I just downloaded the new version.
On my site I use some CSS3 to round the corners on some of the blocks used on the theme. Opera (like IE) has always had a problem with this stuff and instead of seeing rounded corners I just saw very square corners. I was hoping the Opera side of this problem would now be gone but alas, no, the problem is still there. They have included some of the CSS3 stuff but not that which I am interested in. Cannot win ‘em all. Thanks again.
That’s what I hate about designing websites.. you’ve got to try them on all possible browsers and each displays it differently
Lucky I’m just a developer on my full time work!
The Acid3 test is a rendering test for browsers. Firefox 3 gets a 71, for example;

Oh, I actually meant to put a link on the “What is ACID 3″ sentence to Wikipaedia before. Post updated
but thanks for putting it into a simpler term
Looks like you have good knowledge about CSS and other HTML Stuff.
Thanks for the info.
Umm honestly, not really lol. I was just copy-pasting the changelog from the official page. Lyndi is the lady you are looking for on that area
Not an Opera fan but I respect the browser. This one looks like a real winner.
I used to be an Opera fan before I betrayed it and moved to Firefox
