Opera has updated its flagship desktop web browser to version 12.10, which offers several speed improvements, new goodies for web developers and better integration with Apple’s latest Retina screen laptops.

To grab a copy of Opera 12.10 beta for Windows, Mac or Linux, head on over to the Opera download page.

Among Opera 12.10′s standout features is baked-in support for the new SPDY network standard, which offers faster, more secure connections to websites that support it, including big names like Gmail and Twitter.

Opera 12.10 now supports the latest Web Sockets implementation, which fixes the security flaws that previously forced Opera to remove Web Sockets support. Web Sockets are back on by default. Another web standards improvement in Opera 12.10 is support for more “unprefixed” CSS rules, including transitions, transforms, gradients, and animations, all of which will now work without the -o- prefix.

Web developers starting to play with the new CSS Flexible Box Layout Module syntax can now test layouts in Opera 12.10. Check out CSS guru Chris Coyer’s earlier rundown of what’s changed recently with Flexbox.

There’s good news for Mac users in this release — Opera 12.10 is the first to support Apple’s high-res display, making it well worth the update if you’ve got one of the new Retina MacBook Pros. Other Mac improvements include support for new features in OS X Mountain Lion, like the new Notification Center and the built-in content sharing through any social network accounts you’ve set up.

Windows 8 users will be happy to know that basic touch support now works in Windows 8. It’s nowhere near as nice as what you’ll find in IE 10 or Firefox, but it’s a start.
