 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.

@@ -140,6 +159,66 @@ JH/32 Move Redis support from Experimental to mainline, enabled for a build
 JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
       keys are given for lookup.
 
+JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
+      support, by using OpenSSL or GnuTLS library ones.  This means DKIM is
+      only supported when built with TLS support.  The PolarSSL SHA routines
+      are still used when the TLS library is too old for convenient support.
+
+JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
+      openssl_options), for security.  OpenSSL forces this from version 1.1.0
+      server-side so match that on older versions.
+
+JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
+      allocation for $value could be released as the expansion processing
+      concluded, but leaving the global pointer active for it.
+
+JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
+      and to use the domains and local_parts ACL conditions.
+
+JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
+      incorrectly not doubled on cutthrough transmission, hence seen as a
+      body-termination at the receiving system - resulting in truncated mails.
+      Commonly the sender saw a TCP-level error, and retransmitted the message
+      via the normal store-and-forward channel. This could result in duplicates
+      received - but deduplicating mailstores were liable to retain only the
+      initial truncated version.
+
+JH/39 Bug 1781: Fix use of DKIM private-keys having trailing '=' in the base-64.
+
+JH/40 Fix crash in queryprogram router when compiled with EXPERIMENTAL_SRS.
+
+JH/41 Bug 1792: Fix selection of headers to sign for DKIM: bottom-up.  While
+      we're in there, support oversigning also; bug 1309.
+
+JH/42 Bug 1796: Fix error logged on a malware scanner connection failure.
+
+HS/04 Add support for keep_environment and add_environment options.
+
+JH/43 Tidy coding issues detected by gcc --fsanitize=undefined.  Some remain;
+      either intentional arithmetic overflow during PRNG, or testing config-
+      induced overflows.
+
+JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
+      delivery resulted in actual delivery.  Cancel cutthrough before DATA
+      stage.
+
+JH/45 Fix cutthrough, when connection not opened by verify and target hard-
+      rejects a recipient: pass the reject to the originator.
+
+JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
+      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.
