Change log file for Exim from version 4.21
-------------------------------------------
+
+Exim version 4.86
+-----------------
+JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
+ expanded.
+
+JH/02 The smtp transport option "multi_domain" is now expanded.
+
+JH/03 The smtp transport now requests PRDR by default, if the server offers
+ it.
+
+JH/04 Certificate name checking on server certificates, when exim is a client,
+ is now done by default. The transport option tls_verify_cert_hostname
+ can be used to disable this per-host. The build option
+ EXPERIMENTAL_CERTNAMES is withdrawn.
+
+JH/05 The value of the tls_verify_certificates smtp transport and main options
+ default to the word "system" to access the system default CA bundle.
+ For GnuTLS, only version 3.0.20 or later.
+
+JH/06 Verification of the server certificate for a TLS connection is now tried
+ (but not required) by default. The verification status is now logged by
+ default, for both outbound TLS and client-certificate supplying inbound
+ TLS connections
+
+
+Exim version 4.85
+-----------------
+TL/01 When running the test suite, the README says that variables such as
+ no_msglog_check are global and can be placed anywhere in a specific
+ test's script, however it was observed that placement needed to be near
+ the beginning for it to behave that way. Changed the runtest perl
+ script to read through the entire script once to detect and set these
+ variables, reset to the beginning of the script, and then run through
+ the script parsing/test process like normal.
+
+TL/02 The BSD's have an arc4random API. One of the functions to induce
+ adding randomness was arc4random_stir(), but it has been removed in
+ OpenBSD 5.5. Detect this OpenBSD version and skip calling this
+ function when detected.
+
+JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
+ cause callback expansion.
+
+TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
+ syntax errors in an expansion can be treated as a string instead of
+ logging or causing an error, due to the internal use of bool_lax
+ instead of bool when processing it.
+
+JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
+ server certificates when making smtp deliveries.
+
+JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.
+
+JH/04 Add ${sort {list}{condition}{extractor}} expansion item.
+
+TL/04 Bugzilla 1216: Add -M (related messages) option to exigrep.
+
+TL/05 GitHub Issue 18: Adjust logic testing for true/false in redis lookups.
+ Merged patch from Sebastian Wiedenroth.
+
+JH/05 Fix results-pipe from transport process. Several recipients, combined
+ with certificate use, exposed issues where response data items split
+ over buffer boundaries were not parsed properly. This eventually
+ resulted in duplicates being sent. This issue only became common enough
+ to notice due to the introduction of conection certificate information,
+ the item size being so much larger. Found and fixed by Wolfgang Breyha.
+
+JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
+ size buffer was used, resulting in syntax errors when an expansion
+ exceeded it.
+
+JH/07 Add support for directories of certificates when compiled with a GnuTLS
+ version 3.3.6 or later.
+
+JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
+ is EXPERIMENTAL_EVENT, the main-configuration and transport options
+ both become "event_action", the variables become $event_name, $event_data
+ and $event_defer_errno. There is a new variable $verify_mode, usable in
+ routers, transports and related events. The tls:cert event is now also
+ raised for inbound connections, if the main configuration event_action
+ option is defined.
+
+TL/06 In test suite, disable OCSP for old versions of openssl which contained
+ early OCSP support, but no stapling (appears to be less than 1.0.0).
+
+JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
+ server certificate names available under the smtp transport option
+ "tls_verify_cert_hostname" now do not permit multi-component wildcard
+ matches.
+
+JH/10 Time-related extraction expansions from certificates now use the main
+ option "timezone" setting for output formatting, and are consistent
+ between OpenSSL and GnuTLS compilations. Bug 1541.
+
+JH/11 Fix a crash in mime ACL when meeting a zero-length parameter in the
+ incoming message.
+
+JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
+ include certificate info, eximon was claiming there were spoolfile
+ syntax errors.
+
+JH/13 Buf 1521: Fix ldap lookup for single-attr request, multiple-attr return.
+
+JH/14 Log delivery-related information more consistently, using the sequence
+ "H=<name> [<ip>]" wherever possible.
+
+
+Exim version 4.84
+-----------------
+TL/01 Bugzilla 1506: Re-add a 'return NULL' to silence complaints from static
+ checkers that were complaining about end of non-void function with no
+ return.
+
+JH/01 Bug 1513: Fix parsing of quoted parameter values in MIME headers.
+ This was a regression intruduced in 4.83 by another bugfix.
+
+JH/02 Fix broken compilation when EXPERIMENTAL_DSN is enabled.
+
+TL/02 Bug 1509: Fix exipick for enhanced spoolfile specification used when
+ EXPERIMENTAL_DSN is enabled. Fix from Wolfgang Breyha.
+
+
+Exim version 4.83
+-----------------
+
+TF/01 Correctly close the server side of TLS when forking for delivery.
+
+ When a message was received over SMTP with TLS, Exim failed to clear up
+ the incoming connection properly after forking off the child process to
+ deliver the message. In some situations the subsequent outgoing
+ delivery connection happened to have the same fd number as the incoming
+ connection previously had. Exim would try to use TLS and fail, logging
+ a "Bad file descriptor" error.
+
+TF/02 Portability fix for building lookup modules on Solaris when the xpg4
+ utilities have not been installed.
+
+JH/01 Fix memory-handling in use of acl as a conditional; avoid free of
+ temporary space as the ACL may create new global variables.
+
+TL/01 LDAP support uses per connection or global context settings, depending
+ upon the detected version of the libraries at build time.
+
+TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
+ to extract and use the src ip:port in logging and expansions as if it
+ were a direct connection from the outside internet. PPv2 support was
+ updated based on HAProxy spec change in May 2014.
+
+JH/02 Add ${listextract {number}{list}{success}{fail}}.
+
+TL/03 Bugzilla 1433: Fix DMARC SEGV with specific From header contents.
+ Properly escape header and check for NULL return.
+
+PP/01 Continue incomplete 4.82 PP/19 by fixing docs too: use dns_dnssec_ok
+ not dns_use_dnssec.
+
+JH/03 Bugzilla 1157: support log_selector smtp_confirmation for lmtp.
+
+TL/04 Add verify = header_names_ascii check to reject email with non-ASCII
+ characters in header names, implemented as a verify condition.
+ Contributed by Michael Fischer v. Mollard.
+
+TL/05 Rename SPF condition results err_perm and err_temp to standardized
+ results permerror and temperror. Previous values are deprecated but
+ still accepted. In a future release, err_perm and err_temp will be
+ completely removed, which will be a backward incompatibility if the
+ ACL tests for either of these two old results. Patch contributed by
+ user bes-internal on the mailing list.
+
+JH/04 Add ${utf8clean:} operator. Contributed by Alex Rau.
+
+JH/05 Bugzilla 305: Log incoming-TLS details on rejects, subject to log
+ selectors, in both main and reject logs.
+
+JH/06 Log outbound-TLS and port details, subject to log selectors, for a
+ failed delivery.
+
+JH/07 Add malware type "sock" for talking to simple daemon.
+
+JH/08 Bugzilla 1371: Add tls_{,try_}verify_hosts to smtp transport.
+
+JH/09 Bugzilla 1431: Support (with limitations) headers_add/headers_remove in
+ routers/transports under cutthrough routing.
+
+JH/10 Bugzilla 1005: ACL "condition =" should accept values which are negative
+ numbers. Touch up "bool" conditional to keep the same definition.
+
+TL/06 Remove duplicated language in spec file from 4.82 TL/16.
+
+JH/11 Add dnsdb tlsa lookup. From Todd Lyons.
+
+JH/12 Expand items in router/transport headers_add or headers_remove lists
+ individually rather than the list as a whole. Bug 1452.
+
+ Required for reasonable handling of multiple headers_ options when
+ they may be empty; requires that headers_remove items with embedded
+ colons must have them doubled (or the list-separator changed).
+
+TL/07 Add new dmarc expansion variable $dmarc_domain_policy to directly
+ view the policy declared in the DMARC record. Currently, $dmarc_status
+ is a combined value of both the record presence and the result of the
+ analysis.
+
+JH/13 Fix handling of $tls_cipher et.al. in (non-verify) transport. Bug 1455.
+
+JH/14 New options dnssec_request_domains, dnssec_require_domains on the
+ dnslookup router and the smtp transport (applying to the forward
+ lookup).
+
+TL/08 Bugzilla 1453: New LDAP "SERVERS=" option allows admin to override list
+ of ldap servers used for a specific lookup. Patch provided by Heiko
+ Schlichting.
+
+JH/18 New options dnssec_lax, dnssec_strict on dnsdb lookups.
+ New variable $lookup_dnssec_authenticated for observability.
+
+TL/09 Bugzilla 609: Add -C option to exiqgrep, specify which exim.conf to use.
+ Patch submitted by Lars Timman.
+
+JH/19 EXPERIMENTAL_OCSP support under GnuTLS. Bug 1459.
+
+TL/10 Bugzilla 1454: New -oMm option to pass message reference to Exim.
+ Requires trusted mode and valid format message id, aborts otherwise.
+ Patch contributed by Heiko Schlichting.
+
+JH/20 New expansion variables tls_(in,out)_(our,peer)cert, and expansion item
+ certextract with support for various fields. Bug 1358.
+
+JH/21 Observability of OCSP via variables tls_(in,out)_ocsp. Stapling
+ is requested by default, modifiable by smtp transport option
+ hosts_request_ocsp.
+
+JH/22 Expansion operators ${md5:string} and ${sha1:string} can now
+ operate on certificate variables to give certificate fingerprints
+ Also new ${sha256:cert_variable}.
+
+JH/23 The PRDR feature is moved from being Experimental into the mainline.
+
+TL/11 Bug 1119: fix memory allocation in string_printing2(). Patch from
+ Christian Aistleitner.
+
+JH/24 The OCSP stapling feature is moved from Experimental into the mainline.
+
+TL/12 Bug 1444: Fix improper \r\n sequence handling when writing spool
+ file. Patch from Wolfgang Breyha.
+
+JH/25 Expand the coverage of the delivery $host and $host_address to
+ client authenticators run in verify callout. Bug 1476.
+
+JH/26 Port service names are now accepted for tls_on_connect_ports, to
+ align with daemon_smtp_ports. Bug 72.
+
+TF/03 Fix udpsend. The ip_connectedsocket() function's socket type
+ support and error reporting did not work properly.
+
+TL/13 Bug 1495: Exiqgrep check if -C config file specified on cli exists
+ and is readable. Patch from Andrew Colin Kissa.
+
+TL/14 Enhance documentation of ${run expansion and how it parses the
+ commandline after expansion, particularly in the case when an
+ unquoted variable expansion results in an empty value.
+
+JH/27 The TLS SNI feature was broken in 4.82. Fix it.
+
+PP/02 Fix internal collision of T_APL on systems which support RFC3123
+ by renaming away from it. Addresses GH issue 15, reported by
+ Jasper Wallace.
+
+JH/28 Fix parsing of MIME headers for parameters with quoted semicolons.
+
+TL/15 SECURITY: prevent double expansion in math comparison functions
+ (can expand unsanitized data). Not remotely exploitable.
+ CVE-2014-2972
+
+
