Over the weekend IBM released IBM Connections 184.108.40.206. I don't intend to cover all the new stuff here, but I figured I would highlight a few things.
First, the release adds new support for Internet Explorer 9 and Firefox 9. Second, there's now integration with IBM Sametime 8.5.2 for presence awareness. Just as before with Sametime 8.5.1, users can see who is online in Connections without installing any additional software on their desktops. This is very cool because it rapidly speeds adoption and eliminates barriers to collaboration. If you are looking for the instructions on how to do that, you can find it here.
Third, administrators who like to run their servers on the latest release of RedHat, they'll be happy to know that RedHat EL 6.1 is now supported as well.
There's also several new controls available to specify how to sort and filter forums (e.g. by answered status), who can respond to community forums (e.g. members-only or everyone), and the ability to specify the default view for forums. I don't intend to cover all the new stuff here, but you can find the fix list for this release is here.
