I installed Ubuntu 14.04 and saw that it showed Ubuntu 13.10 while installing. I could confirm I installed Ubuntu 14.04 when I did this on a terminal:

lsb_release -a

and got this as output:

Distributor ID: Ubuntu
Description:    Ubuntu 14.04 (Developement release)
Release:    14.04
Codename:   trusty

So are the development versions directly cloned from the previous stable releases? If yes, doesn't a radical change like the change to Mir from Xorg be difficult to implement since the underlying platform itself change?

P.S.: I am not sure whether this should be on AO, as this is a question on development release but then such questions have no scope to be asked anywhere else.

This is on-topic as it is not about a 'problem' with a development release. – don.joey Jan 11 '14 at 10:48

The development versions are daily built and they're different from stable releases.
Currently, Ubuntu 14.04 hasn't come to UI freezing stage, so the 'Ubuntu 10.10' thing lurks around.

see Ubuntu 14.04 Release Schedule for more details about Ubuntu's release management procedures.

Actually it's possible to upgrade to the development version even before daily ISOs are released (by using the unsupported Debian-style technique of editing sources.list and doing apt-get dist-upgrade). The daily ISOs are a way of testing if the development release installs, as well as a convenient way to get it. I believe at the very beginning of a development release--which is just after the release of the preceding stable release--that it consists mostly of files copied over from the stable release. But I'm not really sure how this works. If you know you may want to expand this answer. – Eliah Kagan Jan 11 '14 at 15:17
