* New upstream security/bug fix release: (LP: #1116336)
  - Prevent execution of enum_recv from SQL
    The function was misdeclared, allowing a simple SQL command to crash the
    server.  In principle an attacker might be able to use it to examine the
    contents of server memory.  Our thanks to Sumit Soni (via Secunia SVCRP)
    for reporting this issue. (CVE-2013-0255)
  - See HISTORY/changelog.gz for the other bug fixes.
