+fetchmail-6.3.23 (released 2012-12-10, 26106 LoC):
+
+# REGRESSION FIXES
+* Fix compilation with OpenSSL implementations before 0.9.8m that lack
+ SSL_CTX_clear_options. Patch by Earl Chew.
+ Note that the use of older OpenSSL versions with fetchmail is unsupported and
+ *not* recommended.
+
+# BUG FIXES
+* Fix combination of --plugin and -f -. Patch by Alexander Zangerl,
+ to fix Debian Bug#671294.
+* Clean up logfile vs. syslog handling, and in case logfile overrides
+ syslog, send a message to the latter stating where logging goes.
+
+# CHANGES
+* The build process can now be made a bit more silent and concise through
+ ./configure --enable-silent-rules, or by adding "V=0" to the make command.
+
+# WORKAROUNDS
+* Make Maillennium POP3 workarounds less specific, to encompass
+ Maillennium POP3/UNIBOX (Maillennium V05.00c++). Reported by Eddie
+ via fetchmail-users mailing list, 2012-10-13.

+fetchmail-6.3.22 (released 2012-08-29, 26077 LoC):
+
+# SECURITY FIXES
+* for CVE-2012-3482:
+ NTLM: fetchmail mistook an error message that the server sent in response to
+ an NTLM request for protocol exchange, tried to decode it, and crashed while
+ reading from a bad memory location.
+ Also, with a carefully crafted NTLM challenge packet sent from the server, it
+ would be possible that fetchmail conveyed confidential data not meant for the
+ server through the NTLM response packet.
+ Fix: Detect base64 decoding errors, validate the NTLM challenge, and abort
+ NTLM authentication in case of error.
+ See fetchmail-SA-2012-02.txt for further details.
+ Reported by J. Porter Clark.
+
+* for CVE-2011-3389:
+ SSL/TLS (wrapped and STARTTLS): fetchmail used to disable a countermeasure
+ against a certain kind of attack against cipher block chaining initialization
+ vectors (SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS).
+ Whether this creates an exploitable situation, depends on the server and the
+ negotiated ciphers.
+ As a precaution, fetchmail 6.3.22 enables the countermeasure, by clearing
+ SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS.
+
+ NOTE that this can cause connections to certain non-conforming servers to
+ fail, in which case you can set the environment variable
+ FETCHMAIL_DISABLE_CBC_IV_COUNTERMEASURE to any non-empty value when starting
+ fetchmail to re-instate the compatibility option at the expense of security.
+
+ Reported by Apple Product Security.
+
+ For technical details, refer to <http://www.openssl.org/~bodo/tls-cbc.txt>.
+ See fetchmail-SA-2012-01.txt for further details.
+
+# BUG FIX
+* The Server certificate: message in verbose mode now appears on stdout like the
+ remainder of the output. Reported by Henry Jensen, to fix Debian Bug #639807.
+
+* The GSSAPI-related autoconf code now matches gssapi.c better, and uses
+ a different check to look for GSS_C_NT_HOSTBASED_SERVICE.
+ This fixes the GSSAPI-enabled build on NetBSD 6 Beta.
+
+# CHANGES
+* On systems where SSLv2_client_method isn't defined in OpenSSL (such as
+ newer Debian, and Ubuntu starting with 11.10 oneiric ocelot), don't
+ reference it (to fix the build) and if configured, print a run-time error
+ that the OS does not support SSLv2. Fixes Debian Bug #622054,
+ but note that that bug report has a more thorough patch that does away with
+ SSLv2 altogether.
+
+* The security and errata notices fetchmail-{EN,SA}-20??-??.txt are now
+ under the more relaxed CC BY-ND 3.0 license (the noncommercial clause
+ was dropped). The Creative Commons address was updated.
+
+* The Python-related Makefile.am parts were simplified to avoid an automake
+ 1.11.X bug around noinst_PYTHON, Automake Bug #10995.
+
+* Configuring fetchmail without SSL now triggers a configure warning,
+ and asks the user to consider running configure --with-ssl.
+
+# WORKAROUND
+* Some servers, notably Zimbra, return A1234 987 FETCH () in response to
+ a header request, in the face of message corruption. fetchmail now treats
+ these as temporary errors. Report and Patch by Mikulas Patocka, Red Hat.
+
+* Some servers, notably Microsoft Exchange, return "A0009 OK FETCH completed."
+ without any header in response to a header request for meeting reminder
+ messages (with a "meeting.ics" attachment). fetchmail now treats these as
+ transient errors. Report by John Connett, Patch by Sunil Shetye.

+fetchmail-6.3.21 (released 2011-08-21, 26011 LoC):
+
+# CRITICAL BUG FIX
+* The IMAP client no longer inserts NUL bytes into the last line of a message
+ when it is not closed with a LF or CRLF sequence. Reported by Antoine Levitt.
+ As a side effect of the fix, and in order to avoid a full rewrite, fetchmail
+ will now CRLF-terminate the last line fetched through IMAP, even if it is
+ originally not terminated by LF or CRLF. This bears no relevance if your
+ messages end up in mbox, but adds line termination for storages (like Maildir)
+ that do not require that the last line be LF- or CRLF-terminated.
+
+# CONTRIB/ addition
+* There is a patch against fetchnews's source, contrib/rawlog.patch, that can
+ log (and hexdump non-printing characters) raw socket data to a file. It proved
+ useful to debug Antoine's bug described above.
+
+
+fetchmail-6.3.20 (released 2011-06-06, 26005 LoC):
+
+# SECURITY BUG FIXES
+* CVE-2011-1947:
+ STARTTLS: Fetchmail runs the IMAP STARTTLS or POP3 STLS negotiation with the
+ set timeout (default five minutes) now. This was reported missing, with
+ observed fetchmail freezes beyond a week, by Thomas Jarosch.
+ SSL-wrapped connections were unaffected by this timeout, so users of older
+ versions can force ssl-wrapped connections -- if supported by the server --
+ with the --ssl command line or ssl rcfile option.
+ See fetchmail-SA-2011-01.txt for further details.
+
+# BUG FIXES
+* IMAP: Do not search for UNSEEN messages in ranges. Usually, there are very few
+ new messages and most of the range searches result in nothing. Instead, split
+ the long response to make the IMAP driver think that there are multiple lines
+ of response. (Sunil Shetye)
+* Do not print "skipping message" for old messages even in verbose mode. If
+ there are too many old messages, the logs just get filled without any real
+ activity. (Sunil Shetye) (suggested by Yunfan Jiang)
+* Build: fetchmail now always uses its own MD5 implementation rather than trying
+ to find a system library with matched header. The library and header variants
+ found on systems are too diverse, and the code size saving is not worth any
+ more wasted user or programmer time.
+
+# CHANGES
+* Call strlen() only once when removing CRLF from a line. (Sunil Shetye)
+* fetchmail sets Internet domain sockets to "keepalive" mode now. Note that
+ there is no portable way to configure actual timeouts for this mode, and some
+ systems only support a system-wide timeout setting. fetchmail does not
+ attempt to tune the time spans of keepalive mode.

+fetchmail-6.3.19 (released 2010-12-10, 25945 LoC):
+
+# ERRATUM NOTICE ISSUED
+* fetchmail 6.3.18 contains several bug fixes that were considered sufficiently
+ grave to warrant the issue of an erratum notice, fetchmail-EN-2010-03.txt.
+
+# BUG FIXES
+* When specifying multiple local multidrop lists, do not lose wildcard flag.
+ (Affects "user foo is bar baz * is joe here")
+* In multidrop configurations, an asterisk can now appear anywhere in the list
+ of local users, not just at the end.
+* In multidrop mode, header parsing is now more verbose in -vv mode, so that it
+ becomes possible to see which header is used.
+* Make --antispam work from command line (these used to work in rcfiles).
+ Reported by Kees Bakker, BerliOS Bug #17599. (Sunil Shetye)
+* Smoke test XHTML 1.1 validation, and if it fails, skip validating HTML
+ documents. Skip validating Mailbox-Names-UTF7.html. Several systems have
+ broken XHTML 1.1 DTD installations that jeopardize the build.
+ Reported by Mihail Nechkin against FreeBSD port.
+ Workaround for 6.3.18: build in a separate directory, i. e:
+ mkdir build && cd build && ../configure --options-go-here
+* Send a NOOP only after a failed STARTTLS in IMAP. (Sunil Shetye)
+* Demote GSSAPI verbose/debug syslog to INFO severity. Requested by Carlos E. R.
+ and Derek Simkowiak via the fetchmail-users@ mailing list.
+* Do STARTTLS/STLS negotiation in IMAP/POP3 if it is mandatory even if the
+ server capabilities do not show support for upgradation to TLS.
+ To use this, configure --sslproto tls1. (Sunil Shetye)
+* IMAP: Understand empty strings as FETCH response, seen on Yahoo. Reported by
+ Yasin Malli to fetchmail-users@ 2010-12-10.
+ Note that fetchmail continues to expect literals as FETCH response for now.
+
+# DOCUMENTATION
+* The manual page now links to IANA for GSSAPI service names.
