fetchmail 6.3.0 (not yet released officially):

# SECURITY FIX
* The POP3 UIDL code doesn't sufficiently validate/truncate the input
  length, so a (malicious or compromised) server that sends UIDs longer
  than 128 bytes can corrupt fetchmail's stack and crash fetchmail.
  This vulnerability is remotely exploitable to inject code run in a
  root shell. This is tracked under the CVE Name: CAN-2005-2335

# MAJOR INCOMPATIBLE CHANGES
* Remove support for --netsec/-T options, the required inet6_apps library is no
  longer available.
  http://www.inner.net/pub/ipv6/ states, as of 2005-07-03: "/pub/ipv6
  Our IPv6 software is now long defunct. Please find a more modern source."
  I haven't been able to find a more modern source.  Matthias Andree
* Operating systems that do not conform to the Single Unix Specification v2
  (1997) or v3 (2001, aka IEEE Std 1003.1-2001) are no longer supported. They
  may continue to work and non-intrusive patches to support them may be
  accepted.  Matthias Andree

# OBSOLETION WARNINGS
* The MX and host alias lookups that fetchmail performs in multidrop mode are
  obsolete, deprecated and may be removed from a future fetchmail version
  without further notice. Their support for IPv6 (including IPv6-mapped IPv4)
  is unspecified.  Matthias Andree
* The monitor and interface options may also be removed from a future fetchmail
  version as they are not sufficiently portable.

  - fetchmail-6.2.5-random-result.patch (uninitialized variable/opie.c)
* Revised some bogus assertions about POP3 LAST and UIDL use in the
  manual page. UIDL isn't flaky as the man page suggested, but a
  reliability feature. In fact, IMAP4 code is flaky in that it relies on
  the upstream seen flags. (MA)

  Matthias Andree.
* Fix Debian bug #301964, fetchmail leaks sockets when SSL negotiation
  fails. Fix suggested Goswin Brederlow. (MA)
* Really fix Debian Bug#207919 (garbage in Received: lines when smtphost set),
  patch by Tobias Diedrich.  The 6.2.5 NEWS claimed Gregan's patch had fixed
  #207919 but it had fixed #212484 instead and #207919 remained unfixed in

  Darwin. NetBSD PR#28543 (pkg/28543). Matthias Andree.
* The RFC-822 parser no longer strips the last character of bare addresses.
  Matthias Andree
* The IP address matching code was broken and 
  1. didn't search exhaustively, but matched only the first IP address of the
  server's queryname against the IP addresses of the server name to match.
  2. didn't match IP aliases versus MX hosts.  Matthias Andree
* gettext (intl/) has been removed from the fetchmail package. Install GNU
  gettext 0.14 separately for NLS (i18n).  Matthias Andree

  fetchmailconf.py script, which is now installed in the regular python
  directory. Matthias Andree.

  option, which is now supported even without --enable-inet6. Matthias Andree.
* The default distribution format is now bzip2. Matthias Andree.

  getnameinfo() and the macro AF_INET6.  Matthias Andree.
* Received: headers now enclose the for <...> destination address in angle
  brackets for consistency with Postfix.  Matthias Andree.

* Fix MacOS X compilation failures in sink.c (ru_*time has incomplete type).
