Hi,
There was a point release of the stable distribution ("squeeze") this
morning. The list of packages included (aside from those already
released via security.debian.org and a late ia32-libs upload) can be
found at
https://lists.debian.org/debian-stable-announce/2012/09/msg00000.html
The archive side of the point release has now finished and a mirror push
in running, so packages should start appearing on mirrors in the next
couple of hours.
Regards,
Adam
