This Beta Test Windows only release is available for download and all details are posted in the Opera Community Forums
Opera 7.6 beta .exe provided due to heavy forum traffic. Note: a larger file size due to Speech capability.

Major changes: ( excerpt from Opera posting )

Gmail should be working much better than in 7.5x.

One of the first things you will notice when you start Opera is the ability to select whether to use Opera as an Internet suite or as a browser only

Speech-enabled browsing:
You may have noticed the increased size of the install file. This release comes with a set of voice libraries that enable the user to control Opera by speaking commands to it. Opera now supports XHTML+Voice 1.2 and the CSS3 speech module

Opera 7.60 features in-line error pages allowing you to continue to work if a page loading in the background gives an HTTP error

Medium-Screen Rendering: MSR reformats pages so they fit better on smaller screens. The end result is a page that is very close to the original design, but that should not require horizontal scrolling.
