 New Features in Exim

+Version 4.74
+------------
+
+ 1. Exim now supports loading some lookup types at run-time, using your
+    platform's dlopen() functionality.  This has limited platform support
+    and the intention is not to support every variant, it's limited to
+    dlopen().  This permits the main Exim binary to not be linked against
+    all the libraries needed for all the lookup types.

 Version 4.73

+ NOTE: this version is not guaranteed backwards-compatible, please read the
+       items below carefully

  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;

  4. There is now a -bmalware option, restricted to admin users.  This option
     takes one parameter, a filename, and scans that file with Exim's
     malware-scanning framework.  This is intended purely as a debugging aid
     to ensure that Exim's scanning is working, not to replace other tools.
+    Note that the ACL framework is not invoked, so if av_scanner references
+    ACL variables without a fallback then this will fail.
 
  5. There is a new expansion operator, "reverse_ip", which will reverse IP
     addresses; IPv4 into dotted quad, IPv6 into dotted nibble.  Examples:

  9. Routers now support multiple "condition" tests,
 
+10. There is now a runtime configuration option "tcp_wrappers_daemon_name".
+    Setting this allows an admin to define which entry in the tcpwrappers
+    config file will be used to control access to the daemon.  This option
+    is only available when Exim is built with USE_TCP_WRAPPERS.  The
+    default value is set at build time using the TCP_WRAPPERS_DAEMON_NAME
+    build option.
+
+11. [POSSIBLE CONFIG BREAKAGE] The default value for system_filter_user is now
+    the Exim run-time user, instead of root.
+
+12. [POSSIBLE CONFIG BREAKAGE] ALT_CONFIG_ROOT_ONLY is no longer optional and
+    is forced on.  This is mitigated by the new build option
+    TRUSTED_CONFIG_LIST which defines a list of configuration files which
+    are trusted; one per line. If a config file is owned by root and matches
+    a pathname in the list, then it may be invoked by the Exim build-time
+    user without Exim relinquishing root privileges.
+
+13. [POSSIBLE CONFIG BREAKAGE] The Exim user is no longer automatically
+    trusted to supply -D<Macro[=Value]> overrides on the command-line.  Going
+    forward, we recommend using TRUSTED_CONFIG_LIST with shim configs that
+    include the main config.  As a transition mechanism, we are temporarily
+    providing a work-around: the new build option WHITELIST_D_MACROS provides
+    a colon-separated list of macro names which may be overriden by the Exim
+    run-time user.  The values of these macros are constrained to the regex
+    ^[A-Za-z0-9_/.-]*$ (which explicitly does allow for empty values).
