+Exim version 4.87
+-----------------
+JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
+ and 3.4.4 - once the server is enabled to respond to an OCSP request
+ it does even when not requested, resulting in a stapling non-aware
+ client dropping the TLS connection.
+
+TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
+ support variable-length bit vectors. No functional change.
+
+TF/02 Improve the consistency of logging incoming and outgoing interfaces.
+ The I= interface field on outgoing lines is now after the H= remote
+ host field, same as incoming lines. There is a separate
+ outgoing_interface log selector which allows you to disable the
+ outgoing I= field.
+
+JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
+ If not running log_selector +smtp_connection the mainlog would be held
+ open indefinitely after a "too many connections" event, including to a
+ deleted file after a log rotate. Leave the per net connection logging
+ leaving it open for efficiency as that will be quickly detected by the
+ check on the next write.
+
+HS/01 Bug 1671: Fix post transport crash.
+ Processing the wait-<transport> messages could crash the delivery
+ process if the message IDs didn't exist for some reason. When
+ using 'split_spool_directory=yes' the construction of the spool
+ file name failed already, exposing the same netto behaviour.
+
+JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
+ mime_regex ACL conditions.
+
+JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
+ to DSN fail messages (bounces): remote IP, remote greeting, remote response
+ to HELO, local diagnostic string.
+
+JH/05 Downgrade message for a TLS-certificate-based authentication fail from
+ log line to debug. Even when configured with a tls authenticator many
+ client connections are expected to not authenticate in this way, so
+ an authenticate fail is not an error.
+
+HS/02 Add the Exim version string to the process info. This way exiwhat
+ gives some more detail about the running daemon.
+
+JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
+ matter for fast-change records such as DNSBLs.
+
+JH/07 Bug 1678: Always record an interface option value, if set, as part of a
+ retry record, even if constant. There may be multiple transports with
+ different interface settings and the retry behaviour needs to be kept
+ distinct.
+
+JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
+
+JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.
+
+JH/10 Bug 840: fix log_defer_output option of pipe transport
+
+JH/11 Bug 830: use same host for all RCPTS of a message, even under
+ hosts_randomize. This matters a lot when combined with mua_wrapper.
+
+JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
+ ${quote_pgsql:<string>} operator.
+
+JH/13 Bug 1708: avoid misaligned access in cached lookup.
+
+JH/14 Change header file name for freeradius-client. Relevant if compiling
+ with Radius support; from the Gentoo tree and checked under Fedora.
+
+JH/15 Bug 1712: Introduce $prdr_requested flag variable
+
+JH/16 Bug 1714: Permit an empty string as expansion result for transport
+ option transport_filter, meaning no filtering.
+
+JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
+
+JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
+ defaults to "*" (all hosts). The variable is now available when not built
+ with TLS, default unset, mainly to enable keeping the testuite sane.
+ If a server certificate is not supplied (via tls_certificate) an error is
+ logged, and clients will find TLS connections fail on startup. Presumably
+ they will retry in-clear.
+ Packagers of Exim are strongly encouraged to create a server certificate
+ at installation time.
+
+
+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_hostnames
+ 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
+
+JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
+ sites use this now.
+
+JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
+ Status Notification (bounce) messages are now MIME format per RFC 3464.
+ Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
+ under the control of the dsn_advertise_hosts option, and routers may
+ have a dsn_lasthop option.
+
+JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
+ default, modifiable by a malware= option. The list separator for
+ the options can now be changed in the usual way. Bug 68.
+
+JH/10 The smtp_receive_timeout main option is now expanded before use.
+
+JH/11 The incoming_interface log option now also enables logging of the
+ local interface on delivery outgoing connections.
+
+JH/12 The cutthrough-routing facility now supports multi-recipient mails,
+ if the interface and destination host and port all match.
+
+JH/13 Bug 344: The verify = reverse_host_lookup ACL condition now accepts a
+ /defer_ok option.
+
+JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
+ Patch from Andrew Lewis.
+
+JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
+ now supports optional time-restrictions, weighting, and priority
+ modifiers per server. Patch originally by <rommer@active.by>.
+
+JH/16 The spamd_address main option now supports a mixed list of local
+ and remote servers. Remote servers can be IPv6 addresses, and
+ specify a port-range.
+
+JH/17 Bug 68: The spamd_address main option now supports an optional
+ timeout value per server.
+
+JH/18 Bug 1581: Router and transport options headers_add/remove can
+ now have the list separator specified.
+
+JH/19 Bug 392: spamd_address, and clamd av_scanner, now support retry
+ option values.
+
+JH/20 Bug 1571: Ensure that $tls_in_peerdn is set, when verification fails
+ under OpenSSL.
+
+JH/21 Support for the A6 type of dns record is withdrawn.
+
+JH/22 Bug 608: The result of a QUIT or not-QUIT toplevel ACL now matters
+ rather than the verbs used.
+
+JH/23 Bug 1572: Increase limit on SMTP confirmation message copy size
+ from 255 to 1024 chars.
+
+JH/24 Verification callouts now attempt to use TLS by default.
+
+HS/01 DNSSEC options (dnssec_require_domains, dnssec_request_domains)
+ are generic router options now. The defaults didn't change.
+
+JH/25 Bug 466: Add RFC2322 support for MIME attachment filenames.
+ Original patch from Alexander Shikoff, worked over by JH.
+
+HS/02 Bug 1575: exigrep falls back to autodetection of compressed
+ files if ZCAT_COMMAND is not executable.
+
+JH/26 Bug 1539: Add timout/retry options on dnsdb lookups.
+
+JH/27 Bug 286: Support SOA lookup in dnsdb lookups.
+
+JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
+ Normally benign, it bites when the pair was led to by a CNAME;
+ modern usage is to not canoicalize the domain to a CNAME target
+ (and we were inconsistent anyway for A-only vs AAAA+A).
+
+JH/29 Bug 1632: Removed the word "rejected" from line logged for ACL discards.
+
+JH/30 Check the forward DNS lookup for DNSSEC, in addition to the reverse,
+ when evaluating $sender_host_dnssec.
+
+JH/31 Check the HELO verification lookup for DNSSEC, adding new
+ $sender_helo_dnssec variable.
+
+JH/32 Bug 1397: Enable ECDHE on OpenSSL, just the NIST P-256 curve.
+
+JH/33 Bug 1346: Note MAIL cmd seen in -bS batch, to avoid smtp_no_mail log.
+
+JH/34 Bug 1648: Fix a memory leak seen with "mailq" and large queues.
+
+JH/35 Bug 1642: Fix support of $spam_ variables at delivery time. Was
+ documented as working, but never had. Support all but $spam_report.
+
+JH/36 Bug 1659: Guard checking of input smtp commands again pseudo-command
+ added for tls authenticator.
