Canonical, through Allison Randal, announced on October 21st, that the next LTS (Long Term Support) versions of the Ubuntu operating system will be supported for 5 years.
This is wonderful news, as all Ubuntu LTS releases from now on, starting with Ubuntu 12.04 LTS (Precise Pangolin), will be supported for 5 (five) years, instead of 3 (three) years, on the Desktop.
Both the Desktop and Server editions of Ubuntu will be supported for 5 years, keeping the distribution updated for the latest hardware with point releases in the first 2 years.
"Kate and I are scheduling a session at UDS about LTS planning, and we can talk there around practical details."
"For example, flavors that have taken the LTS designation in the past can choose now whether to use the added support and maintenance to extend their own support cycles or stick with 3 years." - said Allison Randal in the announcement.
