A new installer featuring the final Windows Live Wave 2 programs is available for download thanks to Microsoft's early preparations. While not much has changed in the applications themselves since the last beta releases, its just nice to be running the final versions.
You can grab the new Windows Live installer here: http://g.live.com/1rewlive/en/WLInstaller.exe
Messenger is now 8.5.1302.1018 and Mail is now at 12.0.1606 . If you have any problems installing/upgrading from the betas, the following support article should help.
This now supports x64 systems too!
Note: expect more information and downloads later today!
