Hello!
This is based on the wiki at
https://wiki.ubuntu.com/LTS:
Regular releases are released every six months, and receive security updates for nine months.
LTS releases come out every two years, and are supported for five years. LL 1.0.x is now based on the current Ubuntu LTS release, 12.04.
Towards the end of this month, another LTS version, 14.04, will be released. The LL development team will then use it as the core release to develop LL 2.0.
http://askubuntu.com/questions/265680/ub...ease-model describes a rolling release, using Debian Linux as an example:
"Rolling Release means that were (sic) is no definite release date. The only quality assurance that will be done is that maybe some kind of snapshot is defined.
If you look at debian, you find both models.
stable is an ordinary release branch (currently called 'wheezy').
testing is the development branch (currently called 'jessie'). It is renamed to stable if it gets released.
unstable is a rolling release branch (currently called 'sid')."
The LL development team has previously stated that a key LL development point is stability. Therefore, I don't see LL ever being a 'rolling release'. Perhaps by entertaining the idea of rolling releases, Canonical, the developers of Ubuntu, are finally starting to tire of updating everything in a wholesale fashion every six months.
Using LTS releases means one can update versions far less frequently and still receive support. With an LTS release, one isn't REQUIRED to update every six months.
Like trying to update Windows, updating ()Ubuntu can be a crap shoot, even though I've not noticed any issues when doing so. I guess it depends on what one has installed - which, of course, must be reinstalled if one does a 'clean install' every time...
