New Features in Exim
--------------------
test from the snapshots or the CVS before the documentation is updated. Once
the documentation is updated, this file is reduced to a short list.
+Version 4.77
+------------
+
+ 1. New options for the ratelimit ACL condition: /count= and /unique=.
+ The /noupdate option has been replaced by a /readonly option.
+
+ 2. The SMTP transport's protocol option may now be set to "smtps", to
+ use SSL-on-connect outbound.
+
+ 3. New variable $av_failed, set true if the AV scanner deferred; ie, when
+ there is a problem talking to the AV scanner, or the AV scanner running.
+
+
+Version 4.76
+------------
+
+ 1. The global option "dns_use_edns0" may be set to coerce EDNS0 usage on
+ or off in the resolver library.
+
+
+Version 4.75
+------------
+
+ 1. In addition to the existing LDAP and LDAP/SSL ("ldaps") support, there
+ is now LDAP/TLS support, given sufficiently modern OpenLDAP client
+ libraries. The following global options have been added in support of
+ this: ldap_ca_cert_dir, ldap_ca_cert_file, ldap_cert_file, ldap_cert_key,
+ ldap_cipher_suite, ldap_require_cert, ldap_start_tls.
+
+ 2. The pipe transport now takes a boolean option, "freeze_signal", default
+ false. When true, if the external delivery command exits on a signal then
+ Exim will freeze the message in the queue, instead of generating a bounce.
+
+ 3. Log filenames may now use %M as an escape, instead of %D (still available).
+ The %M pattern expands to yyyymm, providing month-level resolution.
+
+ 4. The $message_linecount variable is now updated for the maildir_tag option,
+ in the same way as $message_size, to reflect the real number of lines,
+ including any header additions or removals from transport.
+
+ 5. When contacting a pool of SpamAssassin servers configured in spamd_address,
+ Exim now selects entries randomly, to better scale in a cluster setup.
+
Version 4.74
------------
- 1. Exim now supports loading some lookup types at run-time, using your
+ 1. SECURITY FIX: privilege escalation flaw fixed. On Linux (and only Linux)
+ the flaw permitted the Exim run-time user to cause root to append to
+ arbitrary files of the attacker's choosing, with the content based
+ on content supplied by the attacker.
+
+ 2. Exim now supports loading some lookup types at run-time, using your
platform's dlopen() functionality. This has limited platform support
and the intention is not to support every variant, it's limited to
dlopen(). This permits the main Exim binary to not be linked against
2. A new pipe transport option, "permit_coredumps", may help with problem
diagnosis in some scenarios. Note that Exim is typically installed as
a setuid binary, which on most OSes will inhibit coredumps by default,
- so that safety mechanism would have to be overriden for this option to
+ so that safety mechanism would have to be overridden for this option to
be able to take effect.
3. ClamAV 0.95 is now required for ClamAV support in Exim, unless
forward, we recommend using TRUSTED_CONFIG_LIST with shim configs that
include the main config. As a transition mechanism, we are temporarily
providing a work-around: the new build option WHITELIST_D_MACROS provides
- a colon-separated list of macro names which may be overriden by the Exim
+ a colon-separated list of macro names which may be overridden by the Exim
run-time user. The values of these macros are constrained to the regex
^[A-Za-z0-9_/.-]*$ (which explicitly does allow for empty values).
