 Change log file for Exim from version 4.21
 -------------------------------------------
 
+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.

       Many were false-positives and ignorable, but it's worth fixing the
       former class.
 
+JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
+      for the new environment-manipulation done at startup.  Move the routines
+      from being local to tls.c to being global via the os.c file.
+
+JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
+      an extract embedded as result-arg for a map, the first arg for extract
+      is unavailable so we cannot tell if this is a numbered or keyed
+      extraction.  Accept either.
