+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.
