This release consists of nothing but tiny fixes to 3.0, including one with
security implications. An upgrade is highly recommended.

  * Certain malformed packets could crash the recursor. As far as we can
    determine these packets could only lead to a crash, but as always,
    there are no guarantees. A quick upgrade is highly recommended
    (commits 760, 761). Reported by David Gavarret.

  * Compilation used both cc and gcc, leading to the possibility of
    compiling with different compiler versions (commit 766).

  * rec_control would leave files named lsockXXXXXX around in the
    configured socket-dir. Operators may wish to remove these files from
    their socket-dir (often /var/run), quite a few might have accumulated
    already (commit 767).

  * Recursor would not distinguish between NXDOMAIN and NXRRSET (commit
    756). Reported and debugged by Jorn Ekkelenkamp.

  * Some error messages and trace logging statements were improved
    (commits 756, 758, 759).

  * stderr was closed during daemonizing, but not dupped to /dev/null,
    leading to slight chance of odd behaviour on reporting errors (commit

Operating system specific fixes:

  * The stock Debian sarge Linux kernel, 2.6.8, claims to support epoll
    but fails at runtime. The epoll self-testing code has been improved,
    and PowerDNS will fall back to a select based multiplexer if needed
    (commit 758) Reported by Michiel van Es.

  * Solaris 8 compilation and runtime issues were addressed. See the
    README for details (commit 765). Reported by Juergen Georgi and
    Kenneth Marshall.

  * Solaris 10 x86_64 compilation issues were addressed (commit 755).
    Reported and debugged by Eric Sproul.
