There are always 2 versions of Linux available. The even numbers are
stable kernels which you would pick if you just want to use the system
to do some useful work. 2.0, 2.2, etc are production kernels.
The last number in the 3 digit release number is the sequence number
in the release, 2.0.36 is the 36th release of the 2.0 production kernel,
for example.

There is also a development track using odd numbers, 2.1, 2.3 etc.
These are bleeding edge, may change rapidly and usually are not for the
faint of heart (unless you absolutely need a feature that isn't
available in the production kernel, but then you've been warned).
Eventually, development features get rolled into the production kernel.
This is one of the reasons Linux is so solid, features get a lot of
trial use before being rolled into the production release.

When they decide to roll out 2.4, there will immediately be a 2.5
development track.

Personally, I would not use a development kernel on a CNC machine.
