I’ve uploaded Windows and Macintosh builds of Opera 9.62 to my “Old Versions” of Opera download page.
While Opera 9.62 is not official until it has been published on the front page and the official Opera download page, it’s usually a good sign when builds for Windows, Macintosh and Unix have all been built and are waiting on the servers.
Or if you’re not ready to install it yet and would prefer to wait until it’s officially released then you should expect to see an update notification possibly within the next couple of days.
I do not have a definite list of the changes since 9.61 (yet). However, I think there will be a fix for the zero-day flaw as mentioned above and explained by ZD Net as:
On the same day Opera shipped a browser update with patches for three separate security vulnerabilities, hackers are openly discussion a new zero-day flaw that exposes Windows users to remote code execution attacks.
With Opera 9.61, the Norwegian browser maker corrects an issue where History Search could be used to reveal browser history (rated extremely severe); a Fast Forward bug that allows cross-site scripting (highly severe); and an information disclosure flaw in news feeds (also highly severe).
