The next Alpha version of Opera 11.50 is available via this official website; you will not get it as an update until Beta hits the free market. Opera Next gives you a separate installation of the Opera browser that lets you try our latest pre-release versions without affecting your main Opera installation.
Officially they are calling it Opera Next with an exiting Alpha icon :
The screenshot shows Opera 11.10 and 11.50 Alpha taskbar icons, both are running simultaneously.
Opera will support full hardware acceleration for any operating system now. The greatest feature is extensions in speed dial. Only five extensions are available right now; obviously the number will increase. We tested the weather extension, the clock extension and RSS feed extension. It looks great:

The RSS feed is very nifty feature. Page rendering has been very very fast. Just you will see the server lookup time and it will load the website instantaneously.
Opera Dragonfly fetches the info of the website more fast now. As always, it is a great tool for web designers.
Update : Opera has released 11.52 Build 1100 ; you can download from here.
