Opera 10.5 Beta Adds Win 7 Integration, Private Browsing, Speed Boost

Windows/Mac/Linux: The official Opera 10.5 Beta for Windows has been released, adding greatly improved JavaScript performance, Windows 7 integration, private browsing, complete overhaul of the user interface, and the official beta release is more stable than the previous snapshot.

We’ve already given you a walk-through tour of the new Windows 7 integration features, and showed you some benchmarks of the new “Carakan” JavaScript engine, which runs up to 8x faster than Opera 10 did, but the new official beta for Windows adds stability and some more tweaks to clean up the user interface.

Mac and Linux users also have something new to test, with an Alpha-quality development snapshot of the new release — though you should be warned that it most likely has issues, so make sure to read the notes before deciding to install it. Opera is a free download for all platforms.
