that might affect a running system.
+Exim version 4.92
+-----------------
+
+ * Exim used to manually follow CNAME chains, to a limited depth. In this
+ day-and-age we expect the resolver to be doing this for us, so the loop
+ is limited to one retry unless the (new) config option dns_cname_loops
+ is changed.
+
+Exim version 4.91
+-----------------
+
+ * DANE and SPF have been promoted from Experimental to Supported status, thus
+ the options to enable them in Local/Makefile have been renamed.
+ See current src/EDITME for full details, including changes in dependencies,
+ but loosely: replace EXPERIMENTAL_SPF with SUPPORT_SPF and replace
+ EXPERIMENTAL_DANE with SUPPORT_DANE.
+
+ * Ancient ClamAV stream support, long deprecated by ClamAV, has been removed;
+ if you were building with WITH_OLD_CLAMAV_STREAM enabled then your problems
+ have marginally increased.
+
+ * A number of logging changes; if relying upon the previous DKIM additional
+ log-line, explicit log_selector configuration is needed to keep it.
+
+ * Other incompatible changes in EXPERIMENTAL_* features, read NewStuff and
+ ChangeLog carefully if relying upon an experimental feature such as DMARC.
+ Note that this includes changes to SPF as it was promoted into Supported.
+
+
+Exim version 4.89
+-----------------
+
+ * SMTP CHUNKING in Exim 4.88 did not ensure that received mails had a final
+ newline; attempts to deliver such messages onwards to non-chunking hosts
+ would probably hang, as Exim does not insert the newline before a ".".
+ In 4.89, the newline is added upon receipt. For already-received messages
+ in your queue, try util/chunking_fixqueue_finalnewlines.pl
+ to walk the queue, fixing any affected messages. Note that because a
+ delivery attempt will be hanging, attempts to lock the messages for fixing
+ them will stall; stopping all queue-runners temporarily is recommended.
+
+ * OpenSSL: oldest supported release series is now 1.0.2, which is the oldest
+ supported by the OpenSSL project. If you can build Exim with an older
+ release series, congratulations. If you can't, then upgrade.
+ The file doc/openssl.txt contains instructions for installing a current
+ OpenSSL outside the system library paths and building Exim to use it.
+
+ * FreeBSD: we now always use the system iconv in libc, as all versions of
+ FreeBSD supported by the FreeBSD project provide this functionality.
+
+
+Exim version 4.88
+-----------------
+
+ * The "demime" ACL condition, deprecated for the past 10 years, has
+ now been removed.
+
+ * Old GnuTLS configuration options "gnutls_require_kx", "gnutls_require_mac",
+ and "gnutls_require_protocols" have now been removed. (Inoperative from
+ 4.80, per below; logging warnings since 4.83, again per below).
+
+
+Exim version 4.83
+-----------------
+
+ * SPF condition results renamed "permerror" and "temperror". The old
+ names are still accepted for back-compatability, for this release.
+
+ * TLS details are now logged on rejects, subject to log selectors.
+
+ * Items in headers_remove lists must now have any embedded list-separators
+ doubled.
+
+ * Attempted use of the deprecated options "gnutls_require_kx" et. al.
+ now result in logged warning.
+
+
Exim version 4.82
-----------------
3. Version 4.23 saves the contents of the ACL variables with the message, so
that they can be used later. If one of these variables contains a newline,
there will be a newline character in the spool that will not be interpreted
- correctely by a previous version of Exim. (Exim ignores keyed spool file
+ correctly by a previous version of Exim. (Exim ignores keyed spool file
items that it doesn't understand - precisely for this kind of problem - but
it expects them all to be on one line.)
