Brief Introduction to the Subject:
The version name of a program usually will increase in value, from 1 - 1.01 for minor releases, and 1.99 - 2.0. With versions of Ubuntu (and other programs/operating systems) the releases are tied to a date, and are given a name (such as Saucy, Lucid, etc.) There are also working versions which will be given terms such as Stable, Unstable, and Testing (when looking at Debian GNU/Linux). This determines what software is available in the repositories, and often is tied into the amount of testing which has gone into the system as a whole.
When a version of anything comes out it must be tested if it is to be released to the public. This is where quality assurance/testing comes into play. During the initial phase the testing may be put into Alpha stage for testing with a small amount of people. After improvements the program may be put into Beta phase, which may open the program up for testing to the public, or a closed group of testers. Then it may go to release. This is not always the case, but it is an example.
Moving from one version of a program to another is called "upgrading". It does not always mean that the new program is better, but usually there is a reason the program has been "upgraded".
