Version 1.4.21:
- No significant changes.

Version 1.4.20:
- Added support for authentication mechanism SCRAM-SHA-1 via GNU SASL.
- The new command tls_fingerprint allows one to trust one particular TLS
  certificate, in case tls_trust_file cannot be used for some reason.
- The new script msmtp-gnome-tool.py manages Gnome Keyring passwords for msmtp.

Version 1.4.19:
- When using OpenSSL, msmtp now correctly handles NUL characters in the Common
  Name and Subject Alternative Name fields of certificates. This fixes a 
  security problem. Note that msmtp is not affected by this problem if GnuTLS is
  used.

Version 1.4.18:
- No significant changes.

Version 1.4.17:
- Msmtp now also reads SYSCONFDIR/netrc if the password was not found in 
  ~/.netrc.
- Support for the GNOME keyring was added by Satoru SATOH.

Version 1.4.16:
- No significant changes.

Version 1.4.15:
- The configuration command tls_crl_file was added. This allows to use 
  certificate revocation lists (CRLs) during certificate verification.
- The configuration command tls_min_dh_prime_bits was added. This may be needed
  to use TLS/SSL with servers that use a small Diffie-Hellman (DH) prime size.
- The configuration command tls_priorities was added. This allows to fine tune 
  TLS/SSL session parameters.

Version 1.4.14: 
- The -t option now properly supports Resent-* headers.
- The --read-envelope-from option was added. It allows to read the envelope from
  address from the From header.
- The environment variables SMTPSERVER and EMAIL can be used to configure msmtp
  for simple use cases.
- Support for the Mac OS X keychain was added by Jay Soffian.

Version 1.4.13: 
- Useful scripts are now distributed in the scripts subdirectory.
- The license was updated to GPLv3 or later (source code) and GFDLv1.2 or later
  (documentation).

Version 1.4.12: 
- No significant changes.

Version 1.4.11: 
- Security improvements:
  - TLS requires tls_trust_file or a disabled tls_certcheck now, so that it is 
    not silently vulnerable to man-in-the-middle attacks.
  - NTLM authentication is considered insecure because it is undocumented. It is
    therefore not used automatically without TLS anymore.

Version 1.4.10:
- No significant changes.

Version 1.4.9:
- No significant changes.

Version 1.4.8:
- No significant changes.

Version 1.4.7:
- The configuration command tls_force_sslv3 was added. This is needed to use
  TLS/SSL with some old and broken servers.

Version 1.4.6:
- The options to the configure script have changed! See the first few
  paragraphs of INSTALL for details.
- Optional support for Internationalized Domain Names (IDN) was added. 
  GNU Libidn is required for this.

Version 1.4.5:
- Only minor tweaks.

Version 1.4.4:
- Support for the sendmail -F option (accepted but ignored).
- Removed the OpenSSL exception note from the license information.

Version 1.4.3:
- Automatic envelope-from addresses are only generated when auto_from is enabled
  with the new auto_from command or --auto-from option.
  This allow empty envelope from addresses to be set with the from command or 
  --from option.

Version 1.4.2:
- The 'connect_timeout' setting was replaced by a 'timeout' setting that applies
  to all network operations. The old option and command are still accepted, but 
  they are not restricted to connection attempts anymore.
- Native language support (NLS) was added. Currently the only supported language
  besides english is german, but it is easy to add more translations (hint, 
  hint)!

Version 1.4.1:
- Only bug fixes, no new features.

Version 1.4.0:
- This is the new stable release of msmtp.
  BEWARE: When upgrading from 1.2.4, note that
  - Authentication is not enabled automatically anymore! Insert the command
    "auth on" into account definitions that need it.
  - Some command line options have changed!
- Summary of new features since 1.2.4:
  - Sendmail compatible command line options, including -t, -N, and -R
  - New long options to configure almost everything on the command line
  - Optional account selection with -f/--from
  - Support for a system wide configuration file
  - Optional automatic construction of envelope from addresses
  - More flexible account definitions
  - Configurable connection timeouts
  - Improved log file logging
  - Syslog logging
  - Improved TLS/SSL support
  - Support for LMTP
  - Support for the EXTERNAL and GSSAPI authentication methods
  - Support for .netrc and password prompting
  - Rewritten documentation, available in various formats
- New since 1.3.9:
  - No new features, but minor improvements mainly regarding interoperability
    and performance. And some minor bug fixes.

Version 1.3.9:
- Added support for the .netrc file: If a password is needed but none is given, 
  msmtp will try to find it in ~/.netrc, and if that fails, msmtp will prompt 
  you for it.
- The authentication user name is included in the log if authentication is used.
  Suggested by Jim Fohlin.
- An account from the system configuration file cannot be partially changed in
  the user configuration file anymore; it must be replaced completely instead.
- Added LMTP support.

Version 1.3.8:
- The default values from a defaults section in a system configuration file
  are not valid in the user configuration file anymore, to prevent changes in 
  the system configuration file from breaking user setups.

Version 1.3.7:
- The user configuration file is required to have no more permissions than 
  0600 (user read/write).
- Added specialisation to account definitions. See documentation of the
  account command and the example files.
- Added the new connect_timeout command and --connect-timeout option.
- The password will be prompted for if none is given in the configuration file.

Version 1.3.6:
- New documentation!
  It was rewritten using texinfo, which allows easy generation of html and pdf
  documents.
  The man page is still up to date and will not be dropped.
- A new configuration file command ("defaults") to set default values for all 
  following accounts was added. Suggested by Jim Fohlin.
- Support for EXTERNAL authentication was added.
- You need GnuTLS >= 1.2.0 now if you want GnuTLS support.
- bug fixes!

Version 1.3.5:
- A system wide configuration file SYSCONFDIR/msmtprc will be used if it exists.
  It's settings will be overridden by the the user configuration file.
  Use the --sysconfdir configure option to set SYSCONFDIR to something other 
  than /usr/local/etc.
- If no envelope from address is given, msmtp will construct one using the user
  name and the mail domain (if given).
- New command/options pairs:
  - maildomain/--maildomain to set the domain part of constructed envelope from
    addresses
  - syslog/--syslog to enable logging to syslog

Version 1.3.4:
- Just some cleanups and bugfixes. The built-in CRAM-MD5 code works again.

Version 1.3.3:
- support for Remote Message Queue Starting (RMQS) was added, see option --rmqs
- msmtp can now print information about the peer's TLS certificate.
  Use --serverinfo (or --debug) to see it
- If you want GnuTLS as your TLS library, you need a version >= 1.1.23 now

Version 1.3.2:
- You need gsasl or libgsasl >= 0.2.4 if you want GNU SASL support
- Various bugfixes

Version 1.3.1:
- fixed the -t option

Version 1.3.0:
- INCOMPATIBLE CHANGES:
  - configuration file:
    - The auth command is now *required* to activate authentication. Just 
      setting user name and password is not enough anymore
    - The tls_nostarttls command should be changed to "tls_starttls off",
      though the old command is still supported
    - The tls_nocertcheck command should be changed to "tls_certcheck off",
      though the old command is still supported
  - command line:
    - Changed short options (because of collision with sendmail options):
      -p is now -P
      -F is now -C
      -v is not available anymore, use --version
      -h is not available anymore, use --help
    - If you used -f/--from without -a/--account to override the envelope from
      address of the default account, you have to use --account=default 
      explicitly now, because otherwise msmtp tries to find an account matching
      the from address
- NEW FEATURES:
  - Sendmail compatible interface
  - Almost all options can now be set on the command line
  - Support for the sendmail -t option (read additional recipient addresses 
    from the To, Cc, and Bcc headers of the mail)
  - You can choose the account using the -f/--from option:
    If you use -f/--from but not -a/--account, the first account of the
    configuration file that has a matching envelope from address will be used
  - GSSAPI authentication (you need GNU SASL >= 0.2.3 with GSSAPI support)
  - New command ntlmdomain to set the domain parameter for NTLM authentication
- CHANGES:
  - Long option support on all platforms (thanks to gnulib)
  - Enhanced almost all commands to allow unsetting of features
  - Changed log file information: Instead of conffile/account, log
    information about host, tls, auth, and from.

Version 1.2.4:
- No new features.

Version 1.2.3:
- IPv6 support on Windows systems
- The configuration file supports all commands and arguments related to
  TLS and authentication, even if TLS and/or GNU SASL support is not 
  compiled in
- The GNU SASL library is not required to support DIGEST-MD5 and NTLM 
  anymore. This means you can now use the packaged versions of the library 
  from Gentoo or Debian sarge.
- You can use the -v/--version option to find out which authentication
  methods are supported.

Version 1.2.2:
- Enhancements to the logfile command:
  - All available information is now written to the logfile (new fields: 
    mailsize=..., smtpmsg='...', errormsg='...').
  - Logging to standard output is possible by using "logfile -"

Version 1.2.1:
- No new features.

Version 1.2.0:
- This version can be compiled without TLS/SSL support; use 
  --disable-ssl if you really want that.
- Read the entries for versions 1.1.x for more changes since the last 
  stable version 1.0.0.

Version 1.1.3:
- New option -i for compatibility with mail(1).
- New 'logfile' command; see man page for details.

Version 1.1.2:
- No user visible changes.

Version 1.1.1:
- The tls_nostarttls command now sets the default port to 465 (ssmtp).

Version 1.1.0:
- Support for SMTP command pipelining. On high latency networks, this 
  may increase transmission speed, especially when sending to many
  recipients.
- The short option for --file, -f, has changed to -F
- A new option --from/-f is available to set the envelope from address.
- A new option --serverinfo/-S is available to print information
  about the capabilities and limitations of an SMTP server

- New options: --pretend and --debug

Version 0.7.0:
- Support for DSN (Delivery Status Notifications) was added via
  the new commands 'dsn_notify' and 'dsn_return'.

  certificate checks. Use it if you get certificate check errors but
  still want to use the SMTP server with TLS/SSL.
- The 'nostarttls' command is now called 'tls_nostarttls'. 
  Please update your configuration file.

Version 0.6.5:
- License clarification:
  msmtp is released under the GPL with the additional exemption that
