syslog-ng (3.3.6-1) unstable; urgency=low

  Between Squeeze and Wheezy OpenSSL changed the default certificate
  directory hashing algorithm from MD5 to SHA1, which may affect syslog-ng
  users who use TLS sources or destinations.

  Due to the change in OpenSSL, certificate verification may fail, and one
  will need to update their certificate directories by calling c_rehash in
  them. If you're experiencing verification failures after upgrading
  syslog-ng from Squeeze, consider rehashing your certificate directories.
