Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.81
+-----------------
+
+PP/01 Add -bI: framework, and -bI:sieve for querying sieve capabilities.
+
+PP/02 Make -n do something, by making it not do something.
+ When combined with -bP, the name of an option is not output.
+
+PP/03 Added tls_dh_min_bits SMTP transport driver option, only honoured
+ by GnuTLS.
+
+PP/04 First step towards DNSSEC, provide $sender_host_dnssec for
+ $sender_host_name and config options to manage this, and basic check
+ routines.
+
+PP/05 DSCP support for outbound connections and control modifier for inbound.
+
+PP/06 Cyrus SASL: set local and remote IP;port properties for driver.
+ (Only plugin which currently uses this is kerberos4, which nobody should
+ be using, but we should make it available and other future plugins might
+ conceivably use it, even though it would break NAT; stuff *should* be
+ using channel bindings instead).
+
+PP/07 Handle "exim -L <tag>" to indicate to use syslog with tag as the process
+ name; added for Sendmail compatibility; requires admin caller.
+ Handle -G as equivalent to "control = suppress_local_fixups" (we used to
+ just ignore it); requires trusted caller.
+ Also parse but ignore: -Ac -Am -X<logfile>
+ Bugzilla 1117.
+
+
Exim version 4.80
-----------------
protection layer was required, which is not implemented.
Bugzilla 1254, patch from Wolfgang Breyha.
+PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
+ into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
+ tls_dhparam take prime identifiers. Also unbreak combination of
+ OpenSSL+DH_params+TLSSNI.
+
+PP/39 Disable SSLv2 by default in OpenSSL support.
