Basically the release lost the lirc driver due to a build error. The symptoms would be that your IR receiver would be recognized as a USB device but the lirc daemon wont be able to talk to it. /var/log/messages would show error message saying /dev/lirc missing.
You can track updates to it in the following bug request.

Note: This was fixed in the next kernel update
