Fixed in Postfix version 3.5.8:
[Postfix 3.5 and later] The Postfix SMTP client inserted <CR><LF> into message headers with lines longer than $line_length_limit (default: 2048), causing all subsequent header content to become message body content. Reported by Andreas Weigel.
Fixed in Postfix versions 3.5.8, 3.4.18, 3.3.15, 3.2.20:
[Postfix 2.8 and later] The postscreen daemon did not save a copy of the postscreen_dnsbl_reply_map lookup result. This has no effect when the recommended texthash: lookup table is used, but it could result in stale data with other lookup tables.
[Postfix 2.3 and later] After deleting a recipient with a Milter, the Postfix recipient duplicate filter was not updated; the filter suppressed requests to add the recipient back. Reported by Mehmet Avcioglu.
[Postfix 2.3 and later] Memory leak: the static: maps did not free their casefolding buffer.
[Postfix 2.2 and later] With "smtpd_tls_wrappermode = yes", the smtps service was waiting for a TLS handshake, after processing an XCLIENT command. Reported by Aki Tuomi.
[Postfix 2.0 and later] The smtp_sasl_mechanism_filter implementation ignored table lookup errors, treating them as 'not found'.
[Postfix alpha and later] The code that looks for Delivered-To: headers ignored headers longer than $line_length_limit (default: 2048).

Database and regexp map functionality is now split into separate packages:
- postfix-cdb
- postfix-ldap
- postfix-lmdb
- postfix-mysql
- postfix-pcre
- postfix-pgsql
- postfix-sqlite
Upstream changelog follows.
Postfix 3.0.2
-------------
No delta against 2.11.6.
Postfix 3.0.1
-------------
- Build error when compiling the Postfix SMTP server with SASL support
but no TLS support.
- The DNS "resource record to text" converter, used for xxx_dns_reply_filter
pattern matching, appended a '.' to TXT record resource values.
- The postscreen(8) manpage specified an incorrect Postfix version number
for the postscreen_dnsbl_timeout parameter.
- The postfix-install script expanded macros in parameter values when
trying to detect parameter overrides, causing unnecessary main.cf updates
during "postfix start" etc.
- Some low-level cleanup of UTF-8 string handling with no visible change
in behavior (besides better performance).
Postfix 3.0.0
-------------
- SMTPUTF8 support for internationalized domain names and address
localparts as defined in RFC 6530 and related documents.
- Support for Postfix dynamically-linked libraries and database plugins.
- An OPT-IN safety net for the selective adoption of new Postfix default
settings. If you do nothing, the old Postfix default settings *should*
remain in effect (complain to your downstream maintainer if that is not
the case).
- Support for operations on multiple lookup tables. The
pipemap:{map1,map2...} database type implements a pipeline of lookup
tables where the result from one lookup table becomes a query for
the next table; the unionmap:{map1,map2,...} database type sends the
