	Bugfix (introduced: 20141212): typo in Clang function pointer
	format check, making it a noop. Viktor Dukhovni. File:
	util/sys_defs.h.

	Maintainability: compile-time argument typechecking for
	variadic attribute-value read/write functions. Files:

20141217

	Replaced compile-time argument typechecking based on inline
	functions with an implementation based on ternary expressions
	with unreachable assignments to dummy variables.   This
	should produce the exact same result as the approach based
	on inline functions (which were standardized with C99).
	Files: util/check_arg.h, util/attr.h, util/attr.c.

20141221

	Portability: proof-of-concept template for OpenBSD build
	with shared libpostfix etc. libraries. File: makedefs.

20141223

	Cleanup: compile-time variadic argument type checking for
	attribute-value APIs of vstream, vstream_popen, vstring,
	pipe_command, spawn_command, attr_override, and mail_server
	skeletons.  Based on mostly automatic conversion and checking,

	virtual/virtual.c, xsasl/xsasl_dovecot_server.c.

20141224

	Cleanup: the compile-time argument typechecks for attribute-value
	APIs are now by default implemented with inline functions.
	Compile with -DNO_INLINE to implement the argument typechecks
	with ternary operators and unreachable assignments.  Files:
	util/check_arg.h and its consumers.

20141226

	NetBSD6/7 dynamic linking support. Viktor Dukhovni.

	Cleanup: instead of making up new names, use a consistent
	CA_ prefix for macros that implement compile-time argument
	typechecks for non-protocol attribute-value APIs. This
	transformation and its verification are mechanical.

	Bugfix (introduced: Postfix 1.1, but latent before 3.0):
	"postfix-install: daemon_directory: not found" error with
	an ancient Solaris shell.  Fixed by ALSO resetting IFS after
	the end of a ``while IFS=foo command'' loop; counter to
	expectation, the IFS reset in the loop body executed in a
	child process.  Background: some shells implement "IFS=foo
	command" as a permanent IFS change; this was allowed by
	standards at some point in time.  File: postfix-install.

20141227

	Feature: smtp_address_verify_target (default: rcpt) that
	determines what protocol stage decides if a recipient is
	valid. Specify "data" for servers that reject recipients
	after the DATA command. Files: mantools/postlink,
	proto/postconf.proto, proto/ADDRESS_VERIFICATION_README.html,
	global/mail_params.h, smtp/lmtp_params.c, smtp/smtp.c,
	smtp/smtp.h, smtp/smtp_params.c, smtp/smtp_proto.c.

20141228

	Cleanup: the IDNA conversion routines now accept both ASCII
	and UTF8 inputs. The functions als verify that either their
	result is a valid ASCII domain name or that it converts
	into a valid ASCII domain name. Files: util/midna.c,
	util/midna_test.in, util/midna_test.ref.

20141230

	Cleanup: s/midna/midna_domain/ for better specificity,
	because we also need functions that act only on the domain
	portion of an email address. Files: bounce/bounce_template.c,
	global/midna_adomain.c, posttls-finger/posttls-finger.c,
	smtp/smtp_addr.c, smtpd/smtpd_check.c, tls/tls_client.c,
	util/midna_domain.[hc], util/valid_utf8_hostname.c.

	Infrastructure: function midna_adomain_to_utf8() (and
	midna_adomain_to_ascii) to convert the domain portion of
	an email address before table lookup. Files:
	global/midna_adomain.[hc].

20141230-20140109

	What is described here is the result of four iterations to
	deal with malformed UTF-8 without massively contaminating
	every Postfix program with new error-handling code paths,
	in particular without triggering fatal errors that didn't
	happen before.

	Infrastructure: function casefold() to support caseless
	string comparison, primarily for table lookups. This function
	supports two modes: case folding a la lowercase() for ASCII
	byte values, and UTF-8 case folding. As recommended at
	http://www.w3.org/International/wiki/Case_folding for
	caseless string comparison, this uses the en_US locale to
	avoid surprises. The implementatin handles the entire RFC
	3629 Unicode range (code points U+0000..U+10FFFF including
	surrogates) and is chroot(2) safe. Files: casefold.c,
	stringops.h.

	Infrastructure: revised the midna_domain_to_ascii and
	midna_domain_to_utf8 domain name conversion functions after
	careful reading of the UTS #46 specification, and after
	observing that ICU 4.8 library functions indeed implement
	this spec, at least with default options. In particular,
	midna_domain_to_utf8 takes an UTF-8 domain name and verifies
	that its A-label form will pass the valid_hostname() test.
	File: util/midna_domain.c.

	Infrastructure: handle UTF-8 errors in lookup table keys
	or values without massively contaminating every Postfix
	program with new error-handling code paths, in particular
	without triggering fatal errors that didn't happen before.
	The lookup/update/delete functions log a warning and ignore
	a request with a bad key (it cannot exist); the update
	functions ignore a request to store a bad value (it cannot
	exist); and the lookup function reports a bad value as a
	configuration error (it should not exist, but there it is).
	Table iterators still report all (key, value) pairs in a
	table. Files: util/dict.h, util/dict_open.c, util/dict_utf8.c,
	global/mkmap_open.c.

	Note that with SMTPUTF8 turned on, each table-driven mechanism
	(access, aliases, etc.) needs to make its own decision
	whether UTF-8 syntax is required. We cannot blindly require
	that everything has valid UTF-8 syntax. That would make
	header/body_checks useless for content inspection, because
	headers may be malformed and bodies may contain legitimate
	binary content that isn't UTF-8.

	Note that with SMTPUTF8 turned off, Postfix must remain
	8-bit clean as it always has been. Table operations must
	not complain that something violates UTF-8 syntax rules.

	UTF-8 sanitization in the Postfix SMTP server.  With
	smtputf8_enable=yes, SMTP commands with UTF-8 syntax errors
	are rejected, table lookup results with invalid UTF-8 syntax
	are handled as configuration errors, and UTF-8 syntax errors
	in policy server replies result in execution of the policy
	server's default action.

20150102

	Cleanup: propagate DICT_ERR_CONFIG through the proxymap
	protocol. Files: global/dict_proxy.[hc], proxymap/proxymap.c.

20150106

	Robustness: don't segfault due to excessive recursion in
	tok822_free_tree() after a faulty configuration runs into
	the virtual_alias_recursion_limit.  File: global/tok822_tree.c.

20150109

	Cleanup: the dict debug module now proxies dict flags.
	File: util/dict_debug.c.

	With "smtputf8_enable = yes", the postmap and postalias
	commands now enable UTF-8 by default (use "-u" to disable)
	with one exception: UTF-8 remains disabled for header/body_checks
	emulation (use "-U" to enable).  Files: postmap/postmap.c,
	postalias/postalias.c.

20150110

	Cleanup: the "inline" and "texthash" implementations now
	reuse the "internal" database instead of reinventing the
	wheel.  Files: util/dict_inline.c, util/dict_thash.c.

	As a first step, with "smtputf8_enable = yes" all features
	based on Postfix matchlists enable UTF-8 syntax checks and
	UTF-8 casefolding for table patterns, but NOT YET for string
	patterns. The list of features includes authorized_flush_users,
	authorized_mailq_users, authorized_submit_users, debug_peer_list,
	fast_flush_domains, mydestination, permit_mx_backup_networks,
	qmqpd_authorized_clients, smtp_connection_cache_destinations,
	smtpd_authorized_verp_clients, smtpd_authorized_xclient_hosts,
	smtpd_authorized_xforward_hosts,
	smtpd_client_event_limit_exceptions,
	smtpd_log_access_permit_actions, smtpd_sasl_exceptions_networks,
	the "domains" feature in ldap_table(5), memcache_table(5)
	mysql_table(5), pgsql_table(5) and sqlite_table(5),
	virtual_alias_domains, virtual_mailbox_domains.

20150111

	Cleanup: simplified the interposition layer that adds UTF-8
	support to Postfix lookup tables. Files: util/dict_utf8.c.

	With "smtputf8_enable = yes", Enable UTF-8 syntax checks
	and UTF-8 casefolding for SMTP server access maps, alias_maps,
	canonical_maps, fallback_transport_maps,
	lmtp_tls_session_cache_database, local_recipient_maps,
	mailbox_command_maps, mailbox_transport_maps, rbl_reply_maps,
	recipient_bcc_maps, recipient_canonical_maps, relay_recipient_maps,
	relocated_maps, sender_bcc_maps, sender_canonical_maps,
	sender_dependent_relayhost_maps, sender_dependent_transport_maps,
	smtp_generic_maps, smtp_sasl_auth_cache_name,
	smtp_sasl_password_maps, smtp_tls_per_site, smtp_tls_policy_maps,
	smtp_tls_session_cache_database, smtpd_sender_login_maps,
	smtpd_tls_session_cache_database, transport_maps,
	virtual_alias_maps, virtual_gid_maps, virtual_mailbox_maps,
	virtual_uid_maps.

20150112

	Infrastructure: support for UTF-8 casefolding in match_lists.
	Instead of using strcasecmp(), casefold all fixed-string
	patterns during initialization, casefold a search string
	at the beginning of the search, and use strcmp() for
	comparison.  Files: util/casefold.c util/dict.h, util/dict_utf8.c,
	util/match_list.c, util/match_list.h, util/match_ops.c,
	util/stringops.h, global/addr_match_list.c, global/domain_list.c,
	global/namadr_list.c, global/string_list.c.

20150113

	Cleanup: show the configuration parameter name in error
	messages while parsing or searching match_list-based features
	such as mydestination, relay_domains and a few dozen more.
	Files: cleanup/cleanup_init.c, flush/flush.c,
	global/addr_match_list.c, global/debug_peer.c,

	smtpd/smtpd_check.c, trivial-rewrite/resolve.c,
	util/match_list.[hc], util/match_ops.c.

	Cleanup: apply printable() to all bounce(8) service
	string-valued protocol fields. File: bounce/bounce.c.

	Apparenly the UCI 4.8 ucasemap_utf8FoldCase() function does
	not complain about UTF-8 syntax errors, so we add our own
	redundant check. File: util/casefold.c.

20150115

	Bitrot: prepare for future changes in OpenSSL. Viktor
	Dukhovni. Files: tls/tls.h, tls/tls_dh.c, tls/tls_misc.c,
	tls/tls_rsa.c, tls/tls_server.c.

	Documentation: "avoid hash files here, use btree or lmdb
	instead".  File: proto/ADDRESS_VERIFICATION_README.html.

	Safety: virtual_alias_address_length_limit (default: 1000)
	to stop aliasing loops that exponentially increase the
	address length with each iteration. Files: global/mail_params.h,
	mantools/postlink, proto/postconf.proto, cleanup/cleanup.c,
	cleanup/cleanup_init.c, cleanup/cleanup_map1n.c.

20150116

	TLS wrappermode in the Postfix smtp(8) client. This introduces
	a new parameter "smtp_tls_wrappermode" (default: no). Files:
	global/mail_params.h, mantools/postlink, proto/postconf.proto,
	smtp/lmtp_params.c, smtp/smtp.[hc], smtp/smtp_connect.c,
	smtp/smtp_params.c, smtp/smtp_proto.c.

	TLS wrappermode in posttls-finger(1), and some DANE-related
	cleanups. This introduces a new option "-w". Viktor Dukhovni.
	Files: posttls-finger/posttls-finger.c, smtp/smtp_tls_policy.c,
	tls/tls.h, tls/tls_client.c, tls/tls_fprint.c.

20150117

	Cleanup: missing " in \%s\" in postscreen(8) fatal error
	messages. Iain Hibbert. File: postconf/postconf_master.c.

20150118

	Bugfix (introduced: 20140731): when a connection timed out
	before any command was received, the Postfix SMTP server
	"disconnect from" logging would show the content of the
	last SMTP server response (421 4.4.2 $myhostname error:
	timeout exceeded) instead of per-command statistics, because
	there were no statistics to report.  The Postfix SMTP server
	now always logs the total number of commands (commands=x/y)
	even when the client did not send any. This helps logfile
	analyzers to recognize sessions without commands.  File:
	smtpd/smtpd.c.

20150120

	Bugfix (introduced: 20141230-20140109): do not reallocate
	a dictionary handle after it is initialized. This breaks
	CDB. Problem reported by Andreas Schulze. Files: util/dict.h,
	util/dict_alloc.c, util/dict_utf8.c.

	Cleanup: simplified the dict_utf8 wrapper implementation.
	Files: util/dict.h, util/dict_alloc.c, util/dict_utf8.c.

20150121

	Cleanup: undo changes in check_mumble_access() that replaced
	error handling with longjmp() calls. This could introduce
	memory leaks in check_mumble_access() callers. Files:
	smtpd/smtpd_check.c, smtpd/smtpd_error.ref.

20150122

	Cleanup: miscellaneous cruft, typos, comments, error messages.

20150124

	Workaround: nroff has been improved so that "-" comes out as
	some non-ASCII character, unlike HTML where it comes out
	as itself.  Andreas Schulze. This requires jumping a few
	hops to generate HTML and nroff input from the same source
	text.  Files; mantools/srctoman, mantools/postconf2man.

	Cleanup: UTF-8 support in masquerade_domains.  File:
	cleanup/cleanup_masquerade.c.

20150126

	Portability: added missing #ifdef STRCASECMP_IN_STRINGS_H
	for platforms that require it. Files: dns/dns_rr_filter.c,
	milter/milter8.c, posttls-finger/posttls-finger.c,

20150127

	Cleanup: simplified the 20150125 and 20150126 APIs, replacing
	the most-common use cases with convenience macros that have
	fewer arguments. Files: anything that implements or invokes
	casefold*() or str*casecmp().

	Documentation: missing words and typos. Matthew Selsky. Files:
	proto/SMTPUTF8_README.html, util/dict_open.c, util/vstream.c.

20150128

	Bugfix: the ICU casemapping API can report success, while
	producing output that is not null-terminated. But we can
	deal with that. File: util/casefold.c.

	Cleanup: unnecessary buffers. File: util/strcasecmp_utf8.c.

	Cleanup: HTML validator errors. Files: proto/postconf.proto,
	proto/TLS_README.html, proto/MILTER_README.html.

	Great rename from 2.12 to 3.0. Lots of files, 99% mechanical.

	Cleanup: HTML entities in *roff manpage source. File:
	mantools/fixman, proto/postconf.proto, smtpd/smtpd.c,
	trivial-rewrite/trivial-rewrite.c.

20150201

	Usability: in error messages, print the CAfile and CApath
	value in double quotes, to clue in people who specify quoted
	pathnames in main.cf. Viktor Dukhovni. Files: tls/tls_certkey.c
	and testing code in posttls-finger/posttls-finger.c.

20150202

	Cleanup: make posttls-finger -k/-K documentation consistent
	with behavior. File: posttls-finger/posttls-finger.c.

20150203

	Cleanup: API minimization, by making some functions static.
	Files: util/dict.h, util/dict_utf8.c.

20150205

	Preliminary feature: support for building position-independent
	executables (PIE), tested on Fedora Core 20, Ubuntu 14.04,
	FreeBSD 9 and 10, and NetBSD 6. See INSTALL section 4.3 for
	details and limitations. Files: makedefs, proto/INSTALL.html,
	RELEASE_NOTES-3.0.

20150208

	Cleanup: after many years, the access(5) map BCC action is
	part of the stable release. Files: smtpd/smtpd_check.c,
	proto/acces.

20150211

	Cleanup: strncasecmp_utf8() streamlining. Files: util/stringops.h,
	util/allascii.c, util/strcasecmp_utf8.c.

20150214

	Bugfix (introduced: Postfix 3.0): missing #ifdef USE_TLS
	inside #ifdef USE_SASL_AUTH.  Viktor Dukhovni. File:
	smtpd/smtpd.c.

20150217

	Cleanup: missing <string.h> include. File: util/allascii.c.

20150221

	Bugfix (introduced: Postfix 3.0): don't append '.' to the
	DNS resource record value, when converting TXT records to
	the string form that is used used by xxx_dns_reply_filter.
	File: dns/dns_strrecord.c.

20150313

	Documentation: incorrect Postfix version number for
	postscreen_dnsbl_timeout. Quanah Gibson-Mount. File:
	postscreen/postscreen.c.

20150324

	Bugfix (introduced: Postfix 2.6): sender_dependent_relayhost_maps
	ignored the relayhost setting in the case of a DUNNO lookup
	result.  It would use the recipient domain instead.  Viktor
	Dukhovni. Wietse took the pieces of code that enforce the
	precedence of a sender-dependent relayhost, the global
	relayhost, and the recipient domain, and put that code
	together in once place so that it is easier to maintain.
	File: trivial-rewrite/resolve.c.

20150328

	Bugfix (introduced: Postfix 1.1.0): post-install expanded
	macros in parameter values when trying to detect parameter
	overrides, causing unnecessary main.cf updates during Postfix
	start-up. Julian Reich, Viktor Dukhovni, and Wietse.  File:
	conf/post-install.

20150330

	Bitrot: prepare for future changes in OpenSSL API. Viktor
	Dukhovni. File: tls_dane.c.

20150501

	Support for Linux 4.*, and some simplification for future
	makedefs files. Files: makedefs, util/sys_defs.h.

20150718

	Security: opportunistic TLS by default uses "medium" or
	stronger ciphers instead of "export" or stronger. See the
	RELEASE_NOTES file for how to get the old settings back.
	Files: global/mail_params.h, proto/TLS_README.html,
	proto/postconf.proto, and files derived from those.

20150719

	Security: Postfix TLS support by default no longer uses
	SSLv2 or SSLv3.  See the RELEASE_NOTES file for how to get
	the old settings back. Files: global/mail_params.h,
	proto/postconf.proto, and files derived from those.

20150722

	The COMPATIBILITY_README text and HTML files were not
	installed.  File: conf/postfix-files.

20150903

	Workaround: disable DNSSEC support for AIX 7x and earlier.
	The AIX 6/7 resolver(5) API defines RES_USE_DNSSEC without
	defining the "ad" bit.  Viktor Dukhovni.  Files: makedefs,
	proto/INSTALL.html, dns/dns.h.

20150923

	Bugfix (introduced: 20120531-617): the Postfix SMTP server
	used a larger-than-1 VSTREAM buffer to read the HAProxy
	connection hand-off information. This broke TLS wrappermode,
	as the TLS helo packet would end up in the plaintext VSTREAM
	buffer. Reported by Lukas Erlacher.  File: smtpd/smtpd_haproxy.c.

20150924

	Bugfix (introduced: 20090216-24): incorrect postmulti error
	message. Reported by Patrik Koetter. Fix by Viktor Dukhovni.
	File: postmulti/postmulti.c.

	Workaround: don't create a new instance when the template
	main.cf and master.cf files are missing, as happens on
	Debian-like systems. Viktor Dukhovni. File: conf/postmulti-script.

20150925

	Bugfix (introduced: 19970309, fixed 20150421 in development
	release): reset errno before calling readdir(), in order
	to distinguish between an end-of-directory and an error
	condition. File: scandir.c.

20150930

	Bugfix (introduced: 20040124): Milter client panic while
	adding a header, because the PREPEND action used the same
	output function for header_checks and body_checks.  Viktor
	Dukhovni and Wietse. File: cleanup/cleanup_message.c.

	Bugfix (introduced: 20031128): xtext_unquote() did not
	propagate error reports from xtext_unquote_append(), causing
	the decoder to return partial ouput, instead of rejecting
	malformed input. Fix by Krzysztof Wojta.  File: global/xtext.c.

20151003

	Bugfix (copied from xtext): uxtext_unquote() did not propagate
	error reports from uxtext_unquote_append(), causing the
	decoder to return partial output, instead of rejecting
	malformed input.  Found by searching the code for similar
	error patterns as with xtext_unquote().  File: global/uxtext.c.

	Bugfix (introduced: 20141130, fixed around 20150607 in
	development release): the DNS multi-query clients forgot
	to save and restore h_errno when evaluating the aggregate
	result. File: dns/dns_lookup.c.

20151124

	Bugfix (introduced: Postfix 3.0): don't throttle a destination
	after opportunistic TLS failure. Viktor Dukhovni. File:
	smtp/smtp_proto.c.

20160204

	Documentation (introduced: Postfix 3.0): wrong paramester
	name in lmtp_address_verify_target description. File:
	proto/posconf.proto

20160310

	Bugfix (introduced: Postfix 2.6): the Milter SMFIR_CHGFROM
	(replace sender) request lost the sender_bcc_maps address.
	Fixed by moving some record keeping to the sender output
	function.  Files: cleanup/cleanup_envelope.c,
	cleanup/cleanup_addr.c, cleanup/cleanup_milter.c,
	cleanup/cleanup.h, regression tests.

20160410

	Bugfix (introduced: Postfix 2.6): the "bad filetype"
	header_checks pattern falsely rejected Content-Mumble headers
	with ``name="example"; x-apple-part-url="example.com"''.
	Fixed by respecting the ";" separator between content
	attribute values.  Reported by Cedric Knight.  File:
	proto/header_checks.

20160515

	Portability: OpenBSD 6.0. Files: makedefs, util/sys_defs.h.
