[Samba] Is it permissible to file bugs on old versions?

[MargoAndTodd]

Hi All,

I am using CentOS 5.3 (Red Hat Enterprise Linux 5.3 clone).
CentOS and RHEL being what they are, they always use old
stuff to maintain enterprise stability.

$rpm -qa \*samba\*
samba-common-3.0.33-3.7.el5
system-config-samba-1.2.41-3.el5
samba-3.0.33-3.7.el5
samba-client-3.0.33-3.7.el5

Is it permissible to file bugs on these old version,
seeing as Samba is up to 3.3.3?  (And, no, I can
not upgrade until CentOS puts it in YUM.)

Many thanks,
