I was delighted to [read this morning](https://lists.ubuntu.com/archives/ubuntu-devel-announce/2012-January/000922.html) that the Ubuntu Technical Board has approved Xubuntu and Kubuntu to be LTS versions, as well as Edubuntu based on some further discussion. You can read the meeting log [here](https://ubottu.com/meetingology/logs/ubuntu-meeting/2012/ubuntu-meeting.2012-01-09-20.58.moin.txt).
Congrats to the Xubuntu, Kubuntu, and Edubuntu communities!
