[CentOS] Missing update announcements for C4 i386 / x86_64

Hi,

the latest updates for perl, xorg-x11, net-snmp, openoffice.org for C4
were announced for the ia64 and s390(x) archs, but not for i386 and
x86_64 altough they are available on the updates mirrors.
Also, what is the policy for announcements of updates that occurred
after the C5.2 release? I see them on the update mirrors. Shouldn't
these update be also announced independently from the C5.2 release
announcement?

Best regards,
Bernd.
