-Version 4.71

+Version 4.73

-Version 4.70
+ 1. A new main configuration option, "openssl_options", is available if Exim
+    is built with SSL support provided by OpenSSL.  The option allows
+    administrators to specify OpenSSL options to be used on connections;
+    typically this is to set bug compatibility features which the OpenSSL
+    developers have not enabled by default.  There may be security
+    consequences for certain options, so these should not be changed
+    frivolously.
+
+ 2. A new pipe transport option, "permit_coredumps", may help with problem
+    diagnosis in some scenarios.  Note that Exim is typically installed as
+    a setuid binary, which on most OSes will inhibit coredumps by default,
+    so that safety mechanism would have to be overriden for this option to
+    be able to take effect.
+
+
+Version 4.72

 ------------
 
 ------------
 

+ 1. TWO SECURITY FIXES: one relating to mail-spools which are globally
+    writable, the other to locking of MBX folders (not mbox).
+
+ 2. MySQL stored procedures are now supported.
+
+ 3. The dkim_domain transport option is now a list, not a single string, and
+    messages will be signed for each element in the list (discarding
+    duplicates).
+
+ 4. The 4.70 release unexpectedly changed the behaviour of dnsdb TXT lookups
+    in the presence of multiple character strings within the RR. Prior to 4.70,
+    only the first string would be returned.  The dnsdb lookup now, by default,
+    preserves the pre-4.70 semantics, but also now takes an extended output
+    separator specification.  The separator can be followed by a semicolon, to
+    concatenate the individual text strings together with no join character,
+    or by a comma and a second separator character, in which case the text
+    strings within a TXT record are joined on that second character.
+    Administrators are reminded that DNS provides no ordering guarantees
+    between multiple records in an RRset.  For example:
+
+      foo.example.  IN TXT "a" "b" "c"
+      foo.example.  IN TXT "d" "e" "f"
+
+      ${lookup dnsdb{>/ txt=foo.example}}   -> "a/d"
+      ${lookup dnsdb{>/; txt=foo.example}}  -> "def/abc"
+      ${lookup dnsdb{>/,+ txt=foo.example}} -> "a+b+c/d+e+f"
+
+
+Version 4.70 / 4.71
+-------------------
+

  1. Native DKIM support without an external library.
  1. Native DKIM support without an external library.

+    (Note that if no action to prevent it is taken, a straight upgrade will
+    result in DKIM verification of all signed incoming emails.  See spec
+    for details on conditionally disabling)

 
  2. Experimental DCC support via dccifd (contributed by Wolfgang Breyha).

+ 3. There is now a bool{} expansion condition which maps certain strings to
+    true/false condition values (most likely of use in conjuction with the
+    and{} expansion operator).
+
+ 4. The $spam_score, $spam_bar and $spam_report variables are now available
+    at delivery time.
+
+ 5. exim -bP now supports "macros", "macro_list" or "macro MACRO_NAME" as
+    options, provided that Exim is invoked by an admin_user.
+
+ 6. There is a new option gnutls_compat_mode, when linked against GnuTLS,
+    which increases compatibility with older clients at the cost of decreased
+    security.  Don't set this unless you need to support such clients.
+
+ 7. There is a new expansion operator, ${randint:...} which will produce a
+    "random" number less than the supplied integer.  This randomness is
+    not guaranteed to be cryptographically strong, but depending upon how
+    Exim was built may be better than the most naive schemes.
+
+ 8. Exim now explicitly ensures that SHA256 is available when linked against
+    OpenSSL.
+
+ 9. The transport_filter_timeout option now applies to SMTP transports too.
