+This is the Postfix 3.3 (stable) release.
+
+The stable Postfix release is called postfix-3.3.x where 3=major
+release number, 3=minor release number, x=patchlevel. The stable
+release never changes except for patches that address bugs or
+emergencies. Patches change the patchlevel and the release date.
+
+New features are developed in snapshot releases. These are called
+postfix-3.4-yyyymmdd where yyyymmdd is the release date (yyyy=year,
+mm=month, dd=day). Patches are never issued for snapshot releases;
+instead, a new snapshot is released.
+
+The mail_release_date configuration parameter (format: yyyymmdd)
+specifies the release date of a stable release or snapshot release.
+
+If you upgrade from Postfix 3.1 or earlier, read RELEASE_NOTES-3.2
+before proceeding.
+
+License change
+---------------
+
+This software is distributed with a dual license: in addition to the
+historical IBM Public License 1.0, it is now also distributed with the
+more recent Eclipse Public License 2.0. Recipients can choose to take
+the software under the license of their choice. Those who are more
+comfortable with the IPL can continue with that license.
+
+Major changes - compatibility safety net
+----------------------------------------
+
+[20180106] With compatibility_level < 1, the Postfix SMTP server
+now warns for mail that would be blocked by the Postfix 2.10
+smtpd_relay_restrictions feature, without blocking that mail. This
+extends the compatibility safety net for sites that upgrade from
+earlier Postfix versions (questions on the postfix-users list show
+there is a steady trickle). See COMPATIBILITY_README for details.
+
+Major changes - configuration
+-----------------------------
+
+[20170617] The postconf command now warns about unknown parameter
+names in a Postfix database configuration file. As with other unknown
+parameter names, these warnings can help to find typos early.
+
+[20180113] New read-only service_name parameter that contains the
+master.cf service name of a Postfix daemon process (it that is empty
+in a non-daemon process). This can make Postfix SMTP server logging
+logging distinct by setting the syslog_name in master.cf with "-o
+syslog_name=postfix/$service_name" for the "submission" and "smtps"
+services, and can make Postfix SMTP client distinct by setting "-o
+syslog_name=postfix/$service_name" for the "relay" service.
+
+Major changes - container support
+---------------------------------
+
+[20171218] Preliminary support to run Postfix in the foreground,
+with "postfix start-fg". This requires that Postfix multi-instance
+support is disabled. To receive Postfix syslog information on the
+container's host, mount the host's /dev/log socket inside the
+container (example: "docker run -v /dev/log:/dev/log ..."), and
+specify a distinct Postfix "syslog_name" prefix that identifies the
+logging from the Postfix instance. Postfix does not log systemd
+events.
+
+Major changes - database support
+---------------------------------
+
+[20170617] The postconf command warns about unknown parameter names
+in a Postfix database configuration file.
+
+[20171227] The pgsql_table(5) hosts parameter now supports the
+postgresql:// URI syntax. Contributed by Magosányi Árpád.
+
+Major changes - header format
+-----------------------------
+
+[20180010] This release changes the format of 'full name' information
+in Postfix-generated From: headers, when a local program such as
+/bin/mail submits a message without From: header.
+
+Postfix-generated From: headers with 'full name' information are
+now formatted as "From: name <address>" by default. Specify
+"header_from_format = obsolete" to get the earlier form "From:
+address (name)". See the postconf(5) manpage for more details.
+
+Major changes - invisible changes
+---------------------------------
+
+[20170617] Additional paranoia in the VSTRING implementation: a
+null byte after the end of vstring buffers (this is a safety net
+so that C-style string operations won't scribble past the end);
+earlier detection of bad length and precision format string specifiers
+(these are the result of programming error, as Postfix format strings
+cannot be specified externally).
+
+Major changes - milter support
+------------------------------
+
+[20171223] Milter applications can now send RET and ENVID parameters
+in SMFIR_CHGFROM (change envelope sender) requests.
+
+Major changes - mixed IPv6/IPv4 support
+---------------------------------------
+
+[20170505] Workaround for mail delivery problems when 1) both Postfix
+IPv6 and IPv4 support are enabled, 2) some destination announces
+more primary IPv6 MX addresses than primary IPv4 MX addresses, 3)
+the destination is unreachable over IPv6, and 4) Postfix runs into
+the smtp_mx_address_limit before it can try to deliver over IPv4.
+
+When both Postfix IPv6 and IPv4 support are enabled, the Postfix
+SMTP client will now relax MX preferences so that it can schedule
+similar numbers of IPv4 and IPv6 destination addresses. This ensures
+that an IPv6 connectivity problem will not prevent mail from being
+delivered over IPv4 (and vice versa). Specify "smtp_balance_inet_protocols
+= no" to disable this workaround.
+
+Major changes - xclient
+-----------------------
+
+[20171218] The Postfix SMTP server now allows the XCLIENT command
+before STARTTLS when TLS is required. This is useful for servers
+that run behind a reverse proxy server such as nginx.
