 Change log file for Exim from version 4.21
 -------------------------------------------
 

+Exim version 4.80
+-----------------
+
+PP/01 Handle short writes when writing local log-files.
+      In practice, only affects FreeBSD (8 onwards).
+      Bugzilla 1053, with thanks to Dmitry Isaikin.
+
+NM/01 Bugzilla 949 - Documentation tweak
+
+NM/02 Bugzilla 1093 - eximstats DATA reject detection regexps
+      improved.
+
+NM/03 Bugzilla 1169 - primary_hostname spelling was incorrect in docs.
+
+PP/02 Implemented gsasl authenticator.
+
+PP/03 Implemented heimdal_gssapi authenticator with "server_keytab" option.
+
+PP/04 Local/Makefile support for (AUTH|LOOKUP)_*_PC=foo to use
+      `pkg-config foo` for cflags/libs.
+
+PP/05 Swapped $auth1/$auth2 for gsasl GSSAPI mechanism, to be more consistent
+      with rest of GSASL and with heimdal_gssapi.
+
+PP/06 Local/Makefile support for USE_(GNUTLS|OPENSSL)_PC=foo to use
+      `pkg-config foo` for cflags/libs for the TLS implementation.
+
+PP/07 New expansion variable $tls_bits; Cyrus SASL server connection
+      properties get this fed in as external SSF.  A number of robustness
+      and debugging improvements to the cyrus_sasl authenticator.
+
+PP/08 cyrus_sasl server now expands the server_realm option.
+
+PP/09 Bugzilla 1214 - Log authentication information in reject log.
+      Patch by Jeremy Harris.
+
+PP/10 Added dbmjz lookup type.
+
+PP/11 Let heimdal_gssapi authenticator take a SASL message without an authzid.
+
+PP/12 MAIL args handles TAB as well as SP, for better interop with
+      non-compliant senders.
+      Analysis and variant patch by Todd Lyons.
+
+NM/04 Bugzilla 1237 - fix cases where printf format usage not indicated
+      Bug report from Lars Müller <lars@samba.org> (via SUSE), 
+      Patch from Dirk Mueller <dmueller@suse.com>
+
+PP/13 tls_peerdn now print-escaped for spool files.
+      Observed some $tls_peerdn in wild which contained \n, which resulted
+      in spool file corruption.
+
+PP/14 TLS fixes for OpenSSL: support TLS 1.1 & 1.2; new "openssl_options"
+      values; set SSL_MODE_AUTO_RETRY so that OpenSSL will retry a read
+      or write after TLS renegotiation, which otherwise led to messages
+      "Got SSL error 2".
+
+TK/01 Bugzilla 1239 - fix DKIM verification when signature was not inserted
+      as a tracking header (ie: a signed header comes before the signature).
+      Patch from Wolfgang Breyha.
+
+JH/01 Bugzilla 660 - Multi-valued attributes from ldap now parseable as a
+      comma-sep list; embedded commas doubled.
+
+PP/15 LDAP: Check for errors of TLS initialisation, to give correct
+      diagnostics.
+      Report and patch from Dmitry Banschikov.
+
+PP/16 Removed "dont_insert_empty_fragments" fron "openssl_options".
+      Removed SSL_clear() after SSL_new() which led to protocol negotiation
+      failures.  We appear to now support TLS1.1+ with Exim.
+
+PP/17 OpenSSL: new expansion var $tls_sni, which if used in tls_certificate
+      lets Exim select keys and certificates based upon TLS SNI from client.
+      Also option tls_sni on SMTP Transports.  Also clear $tls_bits correctly
+      before an outbound SMTP session.  New log_selector, +tls_sni.
+
+PP/18 Bugzilla 1122 - check localhost_number expansion for failure, avoid
+      NULL dereference.  Report and patch from Alun Jones.
+
+PP/19 DNS resolver init changes for NetBSD compatibility.  (Risk of breakage
+      on less well tested platforms).  Obviates NetBSD pkgsrc patch-ac.
+      Not seeing resolver debug output on NetBSD, but suspect this is a
+      resolver implementation change.
+
+PP/20 Revert part of NM/04, it broke log_path containing %D expansions.
+      Left warnings.  Added "eximon gdb" invocation mode.
+
+PP/21 Defaulting "accept_8bitmime" to true, not false.
+
+PP/22 Added -bw for inetd wait mode support.
+
+PP/23 Added PCRE_CONFIG=yes support to Makefile for using pcre-config to
+      locate the relevant includes and libraries.  Made this the default.
+
+PP/24 Fixed headers_only on smtp transports (was not sending trailing dot).
+      Bugzilla 1246, report and most of solution from Tomasz Kusy.
+
+JH/02 ${eval } now uses 64-bit and supports a "g" suffix (like to "k" and "m").
+      This may cause build issues on older platforms.
+
+PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
+      gnutls_priority_init, ignoring Exim options gnutls_require_kx,
+      gnutls_require_mac & gnutls_require_protocols (no longer supported).
+      Added SNI support via GnuTLS too.
+      Made ${randint:..} supplier available, if using not-too-old GnuTLS.
+
+PP/26 Added EXPERIMENTAL_OCSP for OpenSSL.
+
+PP/27 Applied dnsdb SPF support patch from Janne Snabb.
+
+JH/03 Added expansion variable $tod_epoch_l for a higher-precision time.

+TF/04 Improved ratelimit ACL condition.
+
+      The /noupdate option has been deprecated in favour of /readonly which
+      has clearer semantics. The /leaky, /strict, and /readonly update modes
+      are mutually exclusive. The update mode is no longer included in the
+      database key; it just determines when the database is updated. (This
+      means that when you upgrde Exim will forget old rate measurements.)
+
+      Exim now checks that the per_* options are used with an update mode that
+      makes sense for the current ACL. For example, when Exim is processing a
+      message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
+      per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
+      must specify per_mail/readonly. If you omit the update mode it defaults to
+      /leaky where that makes sense (as before) or /readonly where required.
+
+      The /noupdate option is now undocumented but still supported for
+      backwards compatibility. It is equivalent to /readonly except that in
+      ACLs where /readonly is required you may specify /leaky/noupdate or
+      /strict/noupdate which are treated the same as /readonly.
+
+      A useful new feature is the /count= option. This is a generalization
+      of the per_byte option, so that you can measure the throughput of other
+      aggregate values. For example, the per_byte option is now equivalent
+      to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
+
+      The per_rcpt option has been generalized using the /count= mechanism
+      (though it's more complicated than the per_byte equivalence). When it is
+      used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
+      measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
+      or in a non-SMTP ACL it adds all the recipients in one go. (The latter
+      /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
+      Note that using per_rcpt with a non-readonly update mode in more than
+      one ACL will cause the recipients to be double-counted. (The per_mail
+      and per_byte options don't have this problem.)
+
+      The handling of very low rates has changed slightly. If the computed rate
+      is less than the event's count (usually one) then this event is the first
+      after a long gap. In this case the rate is set to the same as this event's
+      count, so that the first message of a spam run is counted properly.
+
+      The major new feature is a mechanism for counting the rate of unique
+      events. The new per_addr option counts the number of different
+      recipients that someone has sent messages to in the last time period. It
+      behaves like per_rcpt if all the recipient addresses are different, but
+      duplicate recipient addresses do not increase the measured rate. Like
+      the /count= option this is a general mechanism, so the per_addr option
+      is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
+      example, measure the rate that a client uses different sender addresses
+      with the options per_mail/unique=$sender_address. There are further
+      details in the main documentation.
+
+TF/05 Removed obsolete $Cambridge$ CVS revision strings.
+
+TF/06 Removed a few PCRE remnants.
+
+TF/07 Automatically extract Exim's version number from tags in the git
+      repository when doing development or release builds.

+      Bugzilla 879.  Patch from Paul Fisher.
+
+PP/03 Implement SSL-on-connect outbound with protocol=smtps on smtp transport.
+      Heavily based on revision 40f9a89a from Simon Arlott's tree.
