[Novalug] Firefox versioning

I am curious again about software package version numbers. I recall from past experience that
sometimes security patches and bug fixes are put into software packages which may use a slightly
different version number than the main software host site (usually for downloads and installs from a
source tarball, for example). My curiousity was piqued by a Windows Vista set of patches for the
Firefox web browser (the patches are invoked from the firefox setting to notify the user of new
patches) which reflect the firefox software version on the http://www.mozilla.com website using
version number 3.5.6. Looking at the patch information, some of the patches seem to be a very
good idea. I set myself to upgrading firefox on my CentOS 5.3 and Ubuntu 9.04 Jaunty systems.
Both of the two latter systems indicate that they are current on firefox software version via yum
for CentOS and wajig for Ubuntu. The firefox version for those two systems is 3.0.15-3 (CentOS)
and 3.0.15 (Ubuntu 9.04).
My understanding is that 3.5.6 is a major version modification from 3.0.15 (based on my limited
understanding of the significance of the second digit in a version number).
Finally my question: Do I need to uninstall firefox linux package to get the 3.5.x series or are
there linux version number events going on to keep the deps in line?
Ubuntu 9.04 sample:
larkoc at larkoc-Ubuntu:~$ firefox --version
Mozilla Firefox 3.0.15, Copyright (c) 1998 - 2009 mozilla.org
larkoc at larkoc-Ubuntu:~$ sudo wajig upgrade firefox
