For the adventurous out there (that’s you, developers), the Opera 10 browser has just been released in alpha. Opera has a 1 to 2 percent browser market share, depending on what statistics you look at, and will soon likely be surpassed by Google’s Chrome, if it hasn’t been already. But it does have its fans.

The alpha for Opera 10 is based on its Presto 2.2 rendering engine, which it says is 30 percent faster than before. The browser also looks better, with more accurate and clearer fonts. It includes an in-line spell-checker, auto updates, and support of transparent effects on Web pages.

But, as with any alpha, be prepared to deal with bugs.
