deb.torproject.org archive signing key expired

Hello, while trying to update Tor on Debian Wheezy I noticed that the gpg key used to sign the apt archive is now expired.

pub 2048R/886DDD89 2009-09-04 [expires: 2014-09-03] Key fingerprint = A3C4 F0F9 79CA A22C DBA8 F512 EE8C BC9E 886D DD89 uid deb.torproject.org archive signing key sub 2048R/219EC810 2009-09-04 [expires: 2014-08-29]

Thank you.
