Updated: At 2:50 p.m. we added links for Opera 10 beta 3 with Unite, and added a statement from Opera about the crash logging feature.
Opera 10 beta 3 was released Wednesday for Windows, Mac, and Linux users. With a strong European following, the preview version has been able to keep this popular alternative browser competitive by offering page rendering quality comparable to Google Chrome, while offering a robust list of features.
There's now a crash logger that Opera says will make the browser "rock-solid," although what that meant was unclear at press time. Opera spokesman Thomas Ford has since clarified the statement, saying that, "It works like the logger that Windows has when a program stops responding. We can more easily identify and then remediate the root cause of crashes." It is not a sandboxing feature, so crashes that originate in one tab will still affect the entire browser.
Users on slower or dial-up connections should see performance improvements in Opera Turbo, too, although they didn't specify what those changes were or what kind of benchmarks users should expect. If you're seeing dramatically better numbers for Opera Turbo on a slow connection, let me know in the comments.
Notably, Opera Unite remains in alpha development and continues to be a separate entity from the main build of the Opera 10 beta. There's no word on how soon integration will occur, although it is apparently planned for before the public release of Opera 10. Opera 10 beta 3 with Unite can be downloaded for Windows, Mac, and Linux.
