There were two (well, technically three) new releases of the Opera Web Browser last week.
For those using the 8.5x version, it has been updated to 8.54. This update addresses a vulnerability in Macromedia Adobe Flash as well as a couple of bugs. You can grab 8.54 here.
The other two releases deal with pre-beta Opera 9.0. The Opera Desktop Team released two versions last week. A mid-weekly build came on Wednesday, and the normal weekly build came in on Friday.
Hopefully we’ll be getting a Beta RC this week or next.
