+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.
