Opera 10.51 Windows Released

22 Mar/10

Opera 10.51 was released less than three weeks after the release of the Opera 10.50 milestone release. Three public release candidates were released in rapid succession before the final version of Opera 10.51. The new version of the popular web browser fixes many user interface inconsistencies and bugs that have made their release in Opera 10.50, a release that many users thought to be rushed out by the developers to meet the browser ballot screen introduction in the European Union.

Opera 10.50 increased the performance of the web browser by a lot. The Opera browser is now one of the fastest web browsers available on the Internet and the developers promise that Opera 10.51 increases the speed further by up to 27% in the Peacekeeper benchmark compared to Opera 10.50.


The developers have published a post that details more speed and JavaScript improvements in Opera 10.51, for instance the fact that Opera 10.51 passes the Sputnik test of Google Labs better than any other web browser.

Opera 10.51 additionally fixes two security issues making it a recommended update for any Opera user.
