<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I
have had an enquiry from the Network and Security guy. He wants to know why
CentOS 5.5 /RHEL 5 is using a very old version of bind
“bind-chroot-9.3.6-4.P1.el5_5.3” when the latest release that has many security
fixes is on 9.7.3 . I understand that its to maintain a known stable platform
by in introducing new elements etc .. Is there an official explanation /
document that I can direct him to.<o:p></o:p></p>

<p class=MsoNormal>RHEL maintains application binary interfaces during the
lifetime of their releases. Only for applications that can no longer be
feasibly maintained through backporting (ie firefox) do they update the version
mid release.<o:p></o:p></p>

<p class=MsoNormal>A lot of people don't understand the backporting way of
maintaining a stable platform across a release, it took me a while to
appreciate it.<o:p></o:p></p>
