+Since Exim version 4.90

 JH/01 Replace the store_release() internal interface with store_newblock(),
       which internalises the check required to safely use the old one, plus
@@ -77,6 +77,39 @@ JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as
       was marked defer_ok.  Fix to keep the two timeout-detection methods
       separate.
 
+JH/15 Relax results from ACL control request to enable cutthrough, in
+      unsupported situations, from error to silently (except under debug)
+      ignoring.  This covers use with PRDR, frozen messages, queue-only and
+      fake-reject.
+
+HS/01 Fix Buffer overflow in base64d() (CVE-2018-6789)
+
+JH/16 Fix bug in DKIM verify: a buffer overflow could corrupt the malloc
+      metadata, resulting in a crash in free().
+
+PP/01 Fix broken Heimdal GSSAPI authenticator integration.
+      Broken in f2ed27cf5, missing an equals sign for specified-initialisers.
+      Broken also in d185889f4, with init system revamp.
+
+JH/17 Bug 2113: Fix conversation closedown with the Avast malware scanner.
+      Previously we abruptly closed the connection after reading a malware-
+      found indication; now we go on to read the "scan ok" response line,
+      and send a quit.
+
+JH/18 Bug 2239: Enforce non-usability of control=utf8_downconvert in the mail
+      ACL.  Previously, a crash would result.
+
+JH/19 Speed up macro lookups during configuration file read, by skipping non-
+      macro text after a replacement (previously it was only once per line) and
+      by skipping builtin macros when searching for an uppercase lead character.
+
+JH/20 DANE support moved from Experimental to mainline.  The Makefile control
+      for the build is renamed.
+
+JH/21 Fix memory leak during multi-message connections using STARTTLS.  A buffer
+      was allocated for every new TLS startup, meaning one per message.  Fix
+      by only allocating once (OpenSSL) or freeing on TLS-close (GnuTLS).
