It looks like Opera is about to do a follow-up release of 9.61 to fix a couple of bugs that made it into 9.60. The International install file is dated 10/20/2008 01:31:00 PM on the ftp server.
I’ve uploaded Windows and Macintosh builds of Opera 9.61 to my “Old Versions” of Opera download page.
While Opera 9.61 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 9.60 (yet). However, I think there will be a fix for the Opera Link bug that created multiple duplicate copies of bookmarks on the end users computer after synchronizing each time.
