Ubuntu variants to get 12.04 LTS releases
The Ubuntu Technical Board has approved three separate proposals which will see Long Term Support (LTS) editions of the KDE-based Kubuntu, Xfce-based Xubuntu and education-oriented Edubuntu appear alongside Ubuntu 12.04 LTS when it is released in April.
The Kubuntu LTS proposal is the second LTS release of the KDE-based variant, the first having been Kubuntu 10.04 LTS. The developers plan to have a five year support cycle following Canonical's October revision of its desktop LTS plans. The Kubuntu developers say that a 12.04 LTS edition, which would include the stable and mature Qt 4 and KDE 4, should be well timed, as later in the year Qt 5 will arrive and KDE Frameworks 5 will begin development.
The Edubuntu proposal is similar, and tracks the Kubuntu proposal as many of the packages that are not in Ubuntu but are in Edubuntu, are managed by the Kubuntu developers. The Edubuntu developers say that they will be dropping GBrainy, due to Mono dependencies, and iTalc, because it has been abandoned upstream.
For Xubuntu, the LTS proposal is slightly less ambitious, with a shorter three year supported life for the release, during which time the developers promise "best effort" bug fixes for high/critical bugs and Xfce security problems.
