Partly because of the latest theoretical attack against the SHA-1 digest algorithm (details), I created a new GPG key:

sec   4096R/F1393998 2009-05-10
uid                  Pierre Chifflier <chifflier@gmail.com>
uid                  Pierre Chifflier <chifflier@inl.fr>
uid                  Pierre Chifflier <pollux@debian.org>
uid                  pollux <pollux@wzdftpd.net>
uid                  Pierre Chifflier <chifflier@cpe.fr>

It's signed with my old key 0x8D5F40CB, uploaded to keyservers, and will replace my old key.
