Corey let me know that the free Microsoft Live Search application has been updated to version 2.1.3336.34565. Talk about a mouthful of a version number. The new version supposedly brings support for OS versions above 18.104.22.168 but I cannot confirm that. Other than that there is no change log.
If you were having trouble with the previous version you can pick up the new one free at wls.live.com OTA.
Let me know if you notice anything else new in this version.
