Can I Propagate A Change?

[Cornellious Mann]

Let's say I have two versions of my source code...
1.2.1 and 1.3.0.  Version 1.2.1 is in production and
version 1.3.0 is in development.  

If I need to make a change to version 1.2.1, I know
that I have to check out the version, modify the
required file and then commit the modification back
into CVS.  

Is there any way I can get the change to version 1.2.1
to propagate into version 1.3.0?  Let's assumer that
the file I had to modify has not not been modified in
version 1.3.0.

Any help is very much appreciated.
