+Exim version 4.88
+-----------------
+JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
+ supports it and a size is available (ie. the sending peer gave us one).
+
+JH/02 The obsolete acl condition "demime" is removed (finally, after ten
+ years of being deprecated). The replacements are the ACLs
+ acl_smtp_mime and acl_not_smtp_mime.
+
+JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
+ a downgraded non-dane trust-anchor for the TLS connection (CA-style)
+ or even an in-clear connection were permitted. Now, if the host lookup
+ was dnssec and dane was requested then the host is only used if the
+ TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
+ MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
+ if one fails this test.
+ This means that a poorly-configured remote DNS will make it incommunicado;
+ but it protects against a DNS-interception attack on it.
+
+JH/04 Bug 1810: make continued-use of an open smtp transport connection
+ non-noisy when a race steals the message being considered.
+
+JH/05 If main configuration option tls_certificate is unset, generate a
+ selfsigned certificate for inbound TLS connections.
+
+JH/06 Bug 165: hide more cases of password exposure - this time in expansions
+ in rewrites and routers.
+
+JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
+ and logged a warning sing 4.83; now they are a configuration file error.
+
+JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
+ (lacking @domain). Apply the same qualification processing as RCPT.
+
+JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
+
+JH/10 Support ${sha256:} applied to a string (as well as the previous
+ certificate).
+
+JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
+ a cutthrough deliver is pending, as we always want to make a connection.
+ This also avoids re-routing the message when later placing the cutthrough
+ connection after a verify cache hit.
+ Do not update it with the verify result either.
+
+JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
+ when routing results in more than one destination address.
+
+JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
+ signing (which inhibits the cutthrough capability). Previously only
+ the presence of an option was tested; now an expansion evaluating as
+ empty is permissible (obviously it should depend only on data available
+ when the cutthrough connection is made).
+
+JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
+ the relevant preceding SMTP command did not note the pipelining mode.
+
+JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
+ Previously they were not counted.
+
+JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
+ as one having no matching records. Previously we deferred the message
+ that needed the lookup.
+
+JH/17 Fakereject: previously logged as a norml message arrival "<="; now
+ distinguished as "(=".
+
+JH/18 Bug 1867: make the fail_defer_domains option on a dnslookup router work
+ for missing MX records. Previously it only worked for missing A records.
+
+JH/19 Bug 1850: support Radius libraries that return REJECT_RC.
+
+JH/20 Bug 1872: Ensure that acl_smtp_notquit is run when the connection drops
+ after the data-go-ahead and data-ack. Patch from Jason Betts.
