Ubuntu Version Description
 

Hi all,

I have a question, which is why we are naming the versions of Ubuntu as 7.04,7.10,8.04,8.10,11.10 and so on , why it can't be 11.00,11.05 or point some number,is there any specific reason to name the version as .04 & .10 in ubuntu?

I can't say exactly why they chose x.04 and x.10.

What I can say is that releases ending with .10 have a 6 months release cycle, while the .04 versions have a 3 year release cycle and are referred to as Long Term Support (LTS) releases.

Its year.month of release. 7.04 came out in april 2007, etc.. That is also why there is one ubuntu version that isnt .04 or .10- 6.06, which was delayed.

Sorry, not that simple.

All .10 releases are 'normal' ubuntu releases with 18 months of support from release. Odd year .04 releases are also 'normal' ubuntu versions- 7.04, 9.04, 11.04. LTS versions are even year .04- 8.04, 10.04, 12.04.

LTS versions have 3/5 (desktop/sever) support up to 10.04, from 12.04 onward 5 years desktop or sever.

Just to make things even more complicated, not all *buntu even year.04 releases are LTS. Lubuntu 12.04 is a 'normal' release with 18 months of support.

Well you actually answered your own statement when you mentioned the 6 month release cycle. It takes 6 months to get from 4 to 10 and another 6 months to get back to 4 again.
