Opera is a popular browser with some of the best support for standards. Opera 10 promises even faster web surfing, built in spell checker and HTML emails.

The faster web browsing is thanks to a new rendering engine, this is the software used to create the web pages. It also claims to support web standards properly including the Acid3 test (click the link to see how your current browser fares).

Acid3 is an extreme test, a more visible effect will be the sthirdupport for web fonts. Most browsers can only use the fonts installed on the computer. Web designers often give the browser a list of fonts. The font they would actually liked used, a similar but more common font and then let the browser choose its own serif or san serif font. Web fonts let the browser load the font from a website.

Auto-update is one improvement we are pleased to see as it is a simpler process than having to download a installer.

Note that this is the final and official public release of Opera 10.10 which contains Unite.
