Fetchmail Release Notes
=======================

This file is in Unicode charset with UTF-8 encoding.
All dates are in Universal Time unless otherwise noted.

(The `lines' figures total .c, .h, .l, and .y files under version control.
Abbreviations in parentheses are the maintainers who committed the respective
change.  MA = Matthias Andree, ESR = Eric S. Raymond, RF = Rob Funk.)

# DEPRECATED FEATURES AND MAJOR INCOMPATIBLE CHANGE ADVANCE WARNINGS
* The MX and host alias DNS lookups that fetchmail performs in multidrop mode
  are obsolete, deprecated and may be removed from a future fetchmail version.
  They have never supported IPv6 (including IPv6-mapped IPv4) anyhow.
  Non-DNS based alias keywords such as "aka" will remain in fetchmail.
* The monitor and interface options may be removed from a future fetchmail
  version as they are not sufficiently portable.
* POP2 is obsolete.
  Support for POP2 may be removed from a future fetchmail version.
* RPOP is obsolete, support may be removed from a future fetchmail release.
* --sslcertck may become a default setting in a future fetchmail version.
* The multidrop To/Cc guessing code along with the fragile duplicate suppressor
  is deprecated and may be removed from a future release.
* The "envelope Received" option may be removed from a future release, because
  the Received header was never meant to be machine-readable, the format varies
  widely, and various other differences in behavior make parsing Received an
  unreliable undertaking. The enveloper option as such will remain though, in
  order to support Delivered-To, X-Envelope-To, X-Original-To and similar.
  See also <http://home.pages.de/~mandree/mail/multidrop>.
* The --enable-fallback (fall back to MDA if MTA unavailable) may be removed
  from a future fetchmail release.
* The "protocol auto" default inside fetchmail may be removed from a future
  fetchmail release. Explicit configuration of the protocol is recommended.
* Kerberos IV support may be removed from a future fetchmail release.
* SIGHUP wakeup may be removed from a future fetchmail release and cause it
  to terminate.
* Support for operating systems that are not sufficiently POSIX compliant may be
  removed or operation on such systems may be suboptimal for future releases.

fetchmail 6.3.6 (not yet released):

# SECURITY FIXES (CHANGE BEHAVIOUR):
* CVE-2006-5867, fetchmail-SA-2006-02.txt:
  Password disclosure vulnerability. This has several aspects:

  - Fetchmail now implies sslproto 'tls1' if the sslfingerprint or sslcertck
    options are used, to be sure there is a certificate to check against.

  - Fetchmail breaks the connection if the TLS negotiation (or verification, if
    requested) fails with sslproto 'tls1' (also applies if this is implicit).

  - POP3 connections ignored STLS altogether in many circumstances, because
    fetchmail did not probe server capabilities in all situations where it
    should have done that.

  - POP3 connections could retry USER/PASS authentication even if strong
    challenge-response schemes such as CRAM-MD5 had explicitly been requested,
    if these were not advertised in the CAPA response.

  - POP2 is obsolete and does not support STLS or anything beyond password-based
    authentication. The attempt to use STLS or stronger authenticators causes
    connection abort.

  Configurations using --ssl --sslcertck however have been semi-safe in that
  they would not expose the password over the wire.

# SECURITY FIX:
* CVE-2006-5974, fetchmail-SA-2006-03.txt:
  Repair regression in 6.3.5 that crashes fetchmail when a message with invalid
  headers is found while fetchmail's mda option is in use. BerliOS bugs #9364,
  #9412, #9449. Stack backtrace provided by Neil Hoggarth - thanks.

# BUG FIXES:
* Repair --logfile, broken in 6.3.5. BerliOS Bug #9059,
  reported by Brian Harring.
* POP3: Probe capabilities when Kerberos V5 is attempted.
* RPOP: The password is now shrouded in the local logs.
* Robustness: If a stale lockfile cannot be deleted, truncate it to avoid
  trouble later if the PID is recycled by a non-fetchmail process.

# TRANSLATIONS:
* New en_GB (British English) translation by David Lodge.
* Update Japanese (Takeshi Hamasaki), Polish (Jakub Bogusz), Russian (Pavel
  Maryanov) and Vietnamese (Clytie Siddall) translations.

# KNOWN BUGS AND WORKAROUNDS:
  (this section floats upwards through the NEWS to be on top of the list)
* fetchmail does not handle messages without Message-ID header well
  (See sourceforge.net bug #780933)
* Sun Workshop 6 (SPARC) is known to miscompile the lexer in 64-bit mode.
  Either compile 32-bit code or use GCC to compile 64-bit fetchmail.
  Note that fetchmail doesn't take advantage of 64-bit code anyways,
  so compiling 32-bit SPARC code should be fine.
* fetchmail expects Received: headers in a particular format when parsing
  envelopes.
* fetchmail does not track pending deletes over crashes
* the command line interface is a bit narrow-minded sometimes, for instance,
  fetchmail -s doesn't work with a running daemon
* some of the logging output is not very helpful
* some of the documentation is still not up to date

fetchmail 6.3.5 (released 2006-10-09):

# BUG FIXES:
* For protocols such as IMAP that are not delimited by "." lines, truncate the
  input buffer when the message has been completely read, to avoid taking
  trailing garbage into the message if the terminal CRLF is missing. Fixes
  Debian Bug#312415. (Patch suggested by Mike Jones, Manchester Univ.).
* When using NTLM authentication, use regular IMAP response code handler after
  completing NTLM handshake, for robustness and consistency.
  (Taken from the NetBSD portable packages collection, patch-ac.)
* Support Kerberos installations where krb5.h and perhaps roken.h are in
  .../include/krb5.  Taken from NetBSD portable packages collection patch-ae.
* On NetBSD, link against -lroken -lcom_err if --with-kerberos is enabled.
* Drop #include <com_err.h> from Kerberos 5 header file, fixes compile error on
  SUSE Linux 10.0.
* Fix des_pcbc_encrypt compile warnings in kerberos.c line 246.
* If krb5-config provides gssapi library information, use that rather than
  guessing.
* Improve --with-gssapi auto detection for /usr-based GSSAPI installs.
* Fix --with-gssapi builds for NetBSD 3.0.
* Improve KAME/getnameinfo.c portability to Linux libc5 systems.
  Based on a patch by Dan Fandrich.
* Provide INET6 to KAME/getnameinfo.c (only useful on IPv6-enabled systems that
  lack getnameinfo, and there only visible in some Received: headers).
  Found by Dan Fandrich.
* POP3: some UID flags may not be set properly on UIDL lists. (Sunil Shetye)
* Make IMAP4 IDLE work on servers that do not update RECENT counts.
  Reported by Lars Tewes.
* IMAP4 patch by Sunil Shetye:
  - do not depend on server updating RECENT counts at all
  - also enter IDLE loop when messages are present on the server.
* Fix --flush description in the manual page, fetchmail does not mark messages
  seen unless it has successfully delivered them. Suggested by Frederic Marchal.
* Fetchmail no longer attempts to stat the "-" file in daemon mode -- this is a
  special name to read the RC file from stdin, and cannot always be re-read
  anyways. BerliOS bug #7858.
* When looking up ports for a service, the lookup succeeds and the returned
  address family isn't IPv4 or IPv6, properly free the allocated memory from the
  service lookup. Found by Uli Zappe.
* When looking up ports for a service, only look up TCP ports.
* Avoid compiling empty files, to avoid diagnostics from strict compilers.
* If the lockfile ends before the process ID, treat it as stale and unlink it.
  Reported by Justin Pryzby, Debian Bug #376603.
* SIGHUP wake-up behavior was broken since 5.9.13's Cygwin changes, in that for
  non-root users, SIGHUP would abort the first poll and subsequently interfere
  with new polls, and SIGHUP would be ignored for root users. SIGHUP now matches
  documented behavior. SIGUSR1 has always been a wakeup signal for both root
  (undocumented) and non-root users. See also the deprecation warning above.
* Track getaddrinfo() results to properly free them after timeouts and make sure
  that getaddrinfo() isn't interrupted by a timeout (which breaks on MacOS X),
  reported by Uli Zappe.  This should fix Debian Bug#294547 and Bug#377135.
* --logfile is now handled more carefully, errors opening the logfile are
  now reported to the TTY where fetchmail was started from.
* fetchmail now complains and aborts when it cannot properly daemonize itself.
* fix compilation on systems that don't know struct addrinfo (Solaris 2.6).
* ignore SIGPIPE signals and rely on functions to return EPIPE instead. This is
  necessary because the former longjmp() from the signal handler is unsafe and
  makes the whole fetchmail behavior undefined after the event.
* Avoid crash in env.c/host_fqdn if we cannot canonicalize our own hostname.
  Reported by Alexander Holler.
* SSL fix by Miloslav Trmac (Red Hat): free the SSL contexts after the
  connection, to avoid from growing SSL certpaths without bounds, avoid using
  SSL contexts for unrelated connections, and to fix Red Hat Bug #206346.

# CHANGES:
* Rename all fetchmail-internal lock_* functions to fm_lock_*. Obsoletes
  NetBSD portable packages collection patch-ah, patch-ai and patch-aj.
* Configure prints a warning (but proceeds) if Kerberos IV support is enabled.
* In verbose mode, log every IP fetchmail tries to connect to, to avoid
  misleading the user. Suppress EAFNOSUPPORT errors from socket() call, too.
  Fixes Debian Bug #361825, reported by Daniel Baur.
* In idle mode, fetchmail complains about the fetchall option.
* When a connection fails, log not only the IP address, but also host and
  service name and the port number. Log the latter when trying to connect in
  verbose mode, too.
* Keep syslog output at one line per message (this works if no errors occur).
* Fetchmail in verbose mode now logs if it opportunistically upgrades a POP3
  or IMAP connection to TLS security with STLS/STARTTLS.
* fetchmail now supports foo@example.org=bar user mappings for multidrop boxes.
* switch setjmp/longjmp to sigsetjmp/siglongjmp
* IMAP now supports the EXTERNAL authentication method, courtesy of
  Götz 'nimrill' Babin-Ebell, BerliOS patch #1095 with minor changes.
* The sslproto keywords are now case insensitive, courtesy of
  Götz 'nimrill' Babin-Ebell, BerliOS patch #1095.
* When going to sleep, log for how long.  Suggested by Claudia Ludwig.
* When the server name cannot be canonicalized, log the gai_strerror value.

# TRANSLATION UPDATES:
* Catalan/ca (Ernest Adrogué Calveras), Japanese/ja (Takeshi Hamasaki) - also
  made gettext 0.15 ready, Polish/pl (Jakub Bogusz), Russian/ru (Pavel
  Maryanov), Spanish/es (Héctor García Álvarez), Vietnamese/vi (Clytie Siddall)

# CONTRIBUTED SCRIPTS:
* PopDel.py was revised by Joshua Crawford to display the From: address and
  list every email, even if it has no Subject: header; and not delete the wrong
  message in the presence of mail without Subject: headers.

fetchmail 6.3.4 (released 2006-04-14):

# BUG FIXES:
* configure: detect res_* functions properly with newer glibc ABIs.
  Patch by Miloslav Trmac.
* tracepolls: add folder information if available. Reported by Terry Brown.
* lexer: add %option noyywrap to avoid link errors about missing yywrap().
* a few more type fixes for report/snprintf, patch by Miloslav Trmac.
* bouncing: fetchmail would still send "General SMTP/ESMTP error." bounces
  in spite of "no bouncemail" configuration.
* SSL/TLS: if, for a certain server, an sslfingerprint is specified and
  sslcertck is NOT set, suppress printing SSL certificate mismatch errors.
  (Reported by Hannes Erven.)
* SSL/TLS: always print if the sslfingerprint mismatches, even in silent
  mode.  (This is for consistency with certificate verification errors.)

# TRANSLATION UPDATES:
* German/de (Matthias Andree), French/fr (Matthias Andree), Spanish/es (Héctor
  García), Polish/pl (Jakub Bogusz), Japanese/ja (Takeshi Hamasaki)
* New Vietnamese/vi translation (Clytie Siddall).
* Updated French descriptions for the .spec file (Stéphane Schildknecht,
  Luc Pionchon, Matthias Andree).

# CHANGES:
* pidfile: there is a new command-line (--pidfile PATH) and global option for
  the rcfile (set pidfile [=] "/path/to/pidfile") option to allow overriding
  the default location of the PID file.
  Requested by Héctor García, Debian maintainer.
* specgen.sh: Converted to UTF-8 to support translated texts better.

fetchmail 6.3.3 (released 2006-03-30):

# BUG FIXES:
* SEGFAULT: Do not attempt to overwrite the netrc password if none has been
  specified.  This fixes a segmentation fault bug introduced into 6.3.2.
  Fixes BerliOS bug #6234.  BerliOS patch #804 by Craig Leres.
  The patch, as accepted into fetchmail, was available separately from
  <http://download.berlios.de/fetchmail/patch-6.3.2.1-fix-netrc-SIGSEGV.diff>
* SEGFAULT: Work around C libraries that return a NULL in getaddrinfo()'s
  ai_canonname record, to avoid a segfault. Affects for instance FreeBSD 4.10,
  4.11 and 5.3 when dotted quads are given as server names.
  Analysis and fix by Vladimir Olegovich Ravodin (Владимир Олегович Раводин).
* IMAP: fix hangs in NOOP-based IDLE emulation. Reported by Casper Gripenberg
  and Brendan Lynch, fix by Sunil Shetye (his patch was merged) and Brendan Lynch.
* IMAP: Handle other clients concurrently accessing IMAP mailboxes better.
  Fetchmail quits the poll if the EXPUNGE count does not match expectations, and
  servers not updating RECENT counts after EXPUNGE are handled in a better way.
  (Patch by Sunil Shetye.)
* IMAP: Stop sending EXPUNGE after NOOP-idling (patch by Sunil Shetye).
* POP3: fetchmail can now use UIDL in fetchall keep mode, to avoid re-fetching
  the same messages again when the fetchall keyword is removed. Patch by
  Sunil Shetye. For details, please see
  <http://lists.berlios.de/pipermail/fetchmail-users/2006-March/000308.html>
* LMTP: fix bug in LMTP port validation (patch by Miloslav Trmac).
* SDPS: fetchmail no longer replaces the local user ID for an empty envelope
  sender when using the proprietary SDPS extension for POP3.
  Fixes Debian Bug#353575, reported by Roger Lynn.
* SDPS: Warn and disable SDPS if POP3 is disabled to avoid compilation errors.
* fetchmail no longer prints empty lines in verbose mode when using syslog.
* fetchmail no longer prints UID lists in verbose mode when using syslog.
* ./configure --quiet is now quieter (no SSL and fallback-related output).
* Miloslav Trmac's patch (with minor changes) to fix char * sign consistency,
  unused arguments and variables.
* More signedness, unused argument/variable and other warning fixes.

# CHANGES:
* --idle can now be specified on the command line, too.
* --fetchall is now supported on the command-line.
* POP3: Lower default fastuidl span to 4 (i. e. every 4th run fetches the
  whole UIDL list), patch by Sunil Shetye.

# DOCUMENTATION:
* "ssl" is a user option rather than a server option. Patch by Nico Golde.
  Fixes Debian Bug#354661, reported by Keith Hellman.
* The manual page now suggests "--" before the addresses in the sendmail MDA
  example, for safety.
* The FAQ item X9, Domino IMAP omits Content-Transfer-Encoding header, was
  added. Information provided by Anthony Kim on the fetchmail-friends list
  in March 2006.
* Credit Chris Boyle with the NOOP emulation code for IDLE in fetchmail 6.2.4.
  Eric forgot to credit Chris, thanks to Sunil Shetye for providing these links:
  http://lists.ccil.org/pipermail/fetchmail-friends/2003-July/007705.html
  http://lists.ccil.org/pipermail/fetchmail-friends/2003-July/007713.html
* Added a section about RETR vs. TOP to the manual page.
* Changed section/subsection levels in some areas.

fetchmail 6.3.2 (released 2006-01-22):

Unless otherwise noted, changes to this release were made by Matthias Andree.

# SECURITY FIX IN THIS RELEASE
* CVE-2006-0321: Fix segfault or bus error after bouncing a message.  This bug
  was introduced into 6.3.0 when removing alloca(); it caused fetchmail to free
  random memory.  Reported by Nathaniel W. Turner, Debian Bug#348747.
  See fetchmail-SA-2006-01.txt

# INCOMPATIBLE CHANGE:
* Automatically disable the POP3 TOP command if the greeting string contains
  "Maillennium POP3/PROXY server", which is used by comcast and known to
  truncate messages after 80 kByte. Fall back to RETR, and complain if we had
  used TOP otherwise (the warning is printed only once per server in daemon
  mode).  Suggested by Ed Wilts.
  *Note* that this means messages are marked read on these servers, which is a
  deviation from how 6.3.1 behaved, but we have no alternative, comcast haven't
  fixed this bug in years.  Preventing the loss of the remainder of the message
  justifies this incompatible fix.
* fetchmail, since 6.3.0, requires write permission to the directory holding the
  idfile. See the amendment in the 6.3.0 MAJOR INCOMPATIBLE CHANGES section
  below for details. The manual page was updated.

# CHANGES RELEVANT TO PACKAGERS:
* The outdated BUGS document was removed from the distribution.
* Added fetchmail-SA-2006-01.txt to the distribution.

# BUG FIXES:
* SMTP/LMTP cleanup to fix these two bugs:
  - switch back to SMTP after having tried LMTP hosts (multiple smtphost hosts)
  - switch back to LMTP after sending a bounce.
  The patch removes the global state variable that was the root of this problem.
  Patch by Sunil Shetye. (MA)
* Don't complain about fetchall keep in --configdump mode. Bug introduced in
  6.3.0.
* fetchmailconf.py: Fix novice help for Poll interval and fetchall.
  Reported by Justin Pryzby, Debian Bug #344978.
* Some verbose output disappeared in debug mode. Adding further -v options would
  alternate between verbose and debug mode. debug mode now comprises all verbose
  output, and adding more -v options does not switch back from debug to verbose
  mode.
* fetchmail.man: Fix accented characters in Héctor García's name. Merged from
  downstream debian/patches/01_man_page.dpatch.
* Add missing --help text for "--sslcertck" option.
* fetchmailconf.py: Accept --help and --version.
* fetchmail --version  now prints the copyright notice.
* don't complain about READ-ONLY IMAP folders in --fetchall --keep mode.
  Reported Alexander Zangerl, Debian Bug#348964.
* the RPM .spec file now generates a -debuginfo package on newer RPM versions.

fetchmail 6.3.1 (released 2005-12-19):

# SECURITY FIX IN THIS RELEASE
* CVE-2005-4348 Fix segmentation fault (null pointer dereference) in
  multidrop mode with headerless email.  See fetchmail-SA-2005-03.txt.
  Reported by Daniel Drake, patch by Sunil Shetye. (MA)

# OTHER BUG FIXES, DOCUMENTATION AND TRANSLATION UPDATES
* Fix broken default port in POP2. Patch by Stanislav Brabec, SUSE [CZ]. (MA)
* Fix manual page, some lines starting with ' were escaped by \&.
  Reported by Simon Barner. (MA)
* Ship with gettext-0.14.3 again, as 6.2.9-rc10 did. Found by Sunil Shetye. (MA)
* Actually set default SSL certificate path if --sslcertpath is unset.
  Reported by Heino Tiedemann and Rob MacGregor. (MA)
* Remove bogus Netscape IMAP4rev1 Service >= 3.6 warning about BODY[TEXT]
  that we are not using. Patch by Sunil Shetye. (MA)
* Plug potential memory and socket leak when polling multiple folders or when
  the upstream sends bogus message sizes.  Patch by Sunil Shetye. (MA)
* Update Catalan translation, by Ernest Adrogué Calveras. (MA)
* Fix segfault (null pointer dereference) on some operating systems with
  fetchmail's obsolete DNS MX/host alias lookups in multidrop mode.
  Patch by Dr.-Ing. Andreas Haakh. (MA)
* Close SMTP sockets early, to reduce resource usage, trigger earlier delivery
  with some MTAs and avoid SIGPIPE (SIG 13) when the SMTP listener gets bored
  and drops the connection after timeout.  Patch by Sunil Shetye. (MA)
* Don't treat hitting a fetch limit as error.  Patch by Sunil Shetye. (MA)
* Fix negative "messages left on server" on idle/repoll with fetchlimit.
  Patch by Sunil Shetye. (MA)
* Properly track logout stage.  Patch by Sunil Shetye. (MA)
* Preserve error conditions across postconnect script.  Sunil Shetye. (MA)
* Do not trash destination domain if multiple messages are forwarded into the
  same SMTP/LMTP connection. Reported by Joachim Feise, Berlios Bug #5849. (MA)
* Manual page: Add "-md5" to "openssl x509" example in --sslfingerprint
  documentation, since OpenSSL 0.9.8 changed the default to SHA1.
  Suggested by Jason White. (MA)
* Cope with servers that return UID information in response to non-UID
  RFC822.{SIZE|HEADER} requests. Reported by Jason White.
  Patch suggestion by by Sunil Shetye, simplified by MA.

fetchmail 6.3.0 (released 2005-11-30):

# SECURITY FIXES IN THIS RELEASE
* CVE-2005-2335: 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. Edward J. Shornock, Ludwig Nussel. fetchmail-SA-2005-01.txt
* CVE-2005-3088: fetchmailconf now changes the output file to mode 0600 BEFORE
  writing to it, so there is no window where passwords could be read by the
  world. Matthias Andree. fetchmail-SA-2005-02.txt

# 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
* The default for --smtphost is now always "localhost" regardless of
  authentication types and protocols, so as to simplify configurations for
  workstations where the SMTP daemon only listens on the loopback interface.
  Sunil Shetye & Matthias Andree
Amendment, 2006-01-04:
* fetchmail's idfile (.fetchids) is no longer written directly, but the ids are
  written to a temporary file which is renamed into place after being written
  completely. This is to avoid writing incomplete idfiles when running out of
  space, which would cause excessive duplicate refetches of messages, this might
  make matters even worse. This means that fetchmail requires write permission
  on the directory holding the idfile. This will usually affect system-global
  daemons only, for instance, Debian. Found by Dan Jacobson. Matthias Andree.
Escalated to "incompatible", 2006-01-13:
* Try to obtain FQDN as our own host by default, rather than using "localhost".
  If hostname cannot be qualified, complain noisily and continue, unless
  Kerberos, ODMR or ETRN are used (these have always required an FQDN).
  Partial fix of Debian Bug#150137. Fixes Debian Bug#316454.  Matthias Andree

# CHANGES RELEVANT TO PACKAGERS AND USERS
* fetchmailconf is now a shell wrapper that calls the byte-compiled
  fetchmailconf.py script, which is now installed in the regular python
  directory. Matthias Andree.
* The --enable-inet6 configure option was removed. The code is mostly protocol
  agnostic, a fully IPv6 aware OS is expected to provide getaddrinfo(),
  getnameinfo() and the macro AF_INET6.  Matthias Andree.
* gettext (intl/) has been removed from the fetchmail package. Install GNU
  gettext 0.14 separately for NLS (i18n).  Matthias Andree
* Added Russian translation, courtesy of Pavel Maryanov of the
  Russian translation team. (MA)
* Updated and re-enabled Czech translation, by Miloslav Trmac (MA).
* Dropped da=Danish, el=Greek and tr=Turkish translations which have more than
  10% (61+) untranslated or fuzzy messages.  Matthias Andree.

# OTHER USER-VISIBLE CHANGES
* Sunil Shetye's fix to force fetchsizelimit to 1 for APOP and RPOP. (ESR)
* PopDel.py removed from contrib at author's request. (ESR)
* Matthias Andree's fix for Sunil Shetye's fetch-split patch. (ESR)
* Include James Stone's moldremover.py script. (ESR)
* Enable .fetchmailrc permissions checking under Cygwin. (ESR)
* Nalin Dahyabai's fix for POP3 strong authentication. (ESR)
* Revised Nalin Dahyabai's fix for POP3 strong authentication (the
  original version would go into an infinite loop when CAPA failed;
  found by David Greaves.) (MA)
* HOME_ETC patch for PLD Linux. (ESR)
* Sunil Shetye's fix for SSL configuration. (ESR)
* Simon Josefsson's patch for GSS library support. (ESR)

  Patch by Phil Endecott. (RF)
* Build fixes for HESIOD and resolv.h trouble on FreeBSD. (MA)
* Fabrice Bellet's fix for Red Hat bug #113492, fetchmail hangs in IMAP
  mode after EXPUNGE when the server (Dovecot 0.99.10) doesn't update
  RECENT and EXISTS counts. (MA)
* Holger Mauermann's bounce patch, to use a NULL envelope from, not
  write a Return-Path header (both to meet RFC-2821), changed From,
  added Subject header, rewording the human readable part.  Fixes Debian
  bug #316446. (MA)
* Merge Sunil Shetye's time.h handling fix. (MA)
* Merge Gerd von Egidy's patch to avoid a segfault in multidrop/received
  mode when the Received: headers are malformatted. (MA)
* MIME-encode bodies and Subject headers of warning messages, limiting
  the header to 7 bits. (MA)
* Normalize most locale codesets to IANA codesets, based on
  norm_charmap.c by Markus Kuhn. (MA)
* Remove sleep(3) after POP3 login, patch by Brian Candler. (MA)
* Fix option parsing bug that trashes the showdots setting when more
  than one server is configured. Patch by Brian Candler. (MA)
* Honor sslcertpath setting even if sslcertck is unset. Patch by Brian
  Candler. (MA)
* SSL certificate checking fixes, don't display same error message twice
  in succession, make sure that Common Name and fingerprint checking are
  only done once. Print all validation warnings/errors even if not in
  verbose mode. Patch by Brian Candler. (MA)
* Import Bjorn Reese and Daniel Stenberg's MIT-licensed Trio 1.10 from
  http://daniel.haxx.se/projects/trio/ for systems that do not support
  snprintf or vsnprintf. (MA)
* Clean up the horrible #ifdef HAVE_[V]SNPRINTF that made the code
  unreadable. Use Trio where [v]snprintf is/are missing. (MA)
* Default to Linux 2.2 /proc/net/dev format, and use uname(2) to determine the
  kernel version instead of calling uname(1). Thanks to Paul Slootman.  (MA)
* Be more careful when swapping UID lists or writing the .fetchids file,
  requested by Manfred Weihs. (MA)
* Print a warning if multidrop configuration is attempted without
  envelope option. (MA)
* Split information on fetchmail versions before 6.0.0 to a separate
  OLDNEWS file. (MA)
* Merge SuSE patches: (sent by Stanislav Brabec, merged by Matthias Andree)
  - fetchmail-6.2.5-declaration.patch (double sigint_handler decl/getpass.c)
  - fetchmail-6.2.5-implicit-declaration.patch (missing #include)
  - 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)
* Miloslav Trmac's patch for fetchmailconf to support string-type values
  of the "port" variable, avoiding "port None" corruption in .fetchmailrc.
  To fix Redhat Bug #55623 (MA)
