-Since Exim version 4.90
------------------
+Exim version 4.90.1
+-------------------
 
 JH/03 Fix pgsql lookup for multiple result-tuples with a single column.
       Previously only the last row was returned.
 
+JH/04 Bug 2217: Tighten up the parsing of DKIM signature headers. Previously
+      we assumed that tags in the header were well-formed, and parsed the
+      element content after inspecting only the first char of the tag.
+      Assumptions at that stage could crash the receive process on malformed
+      input.
+
+JH/05 Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL.
+      While running the DKIM ACL we operate on the Permanent memory pool so that
+      variables created with "set" persist to the DATA ACL.  Also (at any time)
+      DNS lookups that fail create cache records using the Permanent pool.  But
+      expansions release any allocations made on the current pool - so a dnsdb
+      lookup expansion done in the DKIM ACL releases the memory used for the
+      DNS negative-cache, and bad things result.  Solution is to switch to the
+      Main pool for expansions.
+      While we're in that code, add checks on the DNS cache during store_reset,
+      active in the testsuite.
+      Problem spotted, and debugging aided, by Wolfgang Breyha.
+
+JH/06 Fix issue with continued-connections when the DNS shifts unreliably.
+      When none of the hosts presented to a transport match an already-open
+      connection, close it and proceed with the list.  Previously we would
+      queue the message.  Spotted by Lena with Yahoo, probably involving
+      round-robin DNS.
+
+JH/07 Bug 2214: Fix SMTP responses resulting from non-accept result of MIME ACL.
+      Previously a spurious "250 OK id=" response was appended to the proper
+      failure response.
+
+JH/10 Bug 2223: Fix mysql lookup returns for the no-data case (when the number of
+      rows affected is given instead).
+
+JH/12 Bug 2230: Fix cutthrough routing for nonfirst messages in an initiating
+      SMTP connection.  Previously, when one had more receipients than the
+      first, an abortive onward connection was made.  Move to full support for
+      multiple onward connections in sequence, handling cutthrough connection
+      for all multi-message initiating connections.
+
+JH/13 Bug 2229: Fix cutthrough routing for nonstandard port numbers defined by
+      routers.  Previously, a multi-recipient message would fail to match the
+      onward-connection opened for the first recipient, and cause its closure.
+
+JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as
+      a timeout on read on a GnuTLS initiating connection, resulting in the
+      initiating connection being dropped.  This mattered most when the callout
+      was marked defer_ok.  Fix to keep the two timeout-detection methods
+      separate.
+
+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.
+
