Signed-off-by: Daniel Baumann --- RELEASE_NOTES-3.3 | 124 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 124 insertions(+) create mode 100644 RELEASE_NOTES-3.3 (limited to 'RELEASE_NOTES-3.3') diff --git a/RELEASE_NOTES-3.3 b/RELEASE_NOTES-3.3 new file mode 100644 index 0000000..e3762d8 --- /dev/null +++ b/RELEASE_NOTES-3.3 @@ -0,0 +1,124 @@ +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
" 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. + -- cgit v1.2.3
