-Version 4.95
+Version 4.98
------------
+ 1. A sieve_inbox option for redirect routers
- 1. The fast-ramp two phase queue run support, previously experimental, is
- now supported by default.
+ 2. A "connection_id" variable
- 2. The native SRS support, previously experimental, is now supported. It is
- not built unless specified in the Local/Makefile.
+ 3. Events smtp:fail:protocol and smtp:fail:syntax
- 3. TLS resumption support, previously experimental, is now supported and
- included in default builds.
+ 4. Support for Exim- and Sieve filters can be omitted at build time
- 4. Single-key LMDB lookups, previously experimental, are now supported.
- The support is not built unless specified in the Local/Makefile.
+ 5. JSON and LDAP lookup support, both filter types, PAM, RADIUS, perl, SPF,
+ DKIM, DMARC and ARC support, all the router and authenticator drivers,
+ and all the transport drivers except smtp, can now be built as loadable
+ modules
- 5. Option "message_linelength_limit" on the smtp transport to enforce (by
- default) the RFC 998 character limit.
+ 6. A transport "socks_proxy" may expand to an empty string, specifying no
+ proxying.
- 6. An option to ignore the cache on a lookup.
+ 7. Variables $dmarc_alignment_spf and $dmarc_alignment_dkim.
- 7. Quota checking during reception (i.e. at SMTP time) for appendfile-
- transport-managed quotas.
+Version 4.98
+------------
+ 1. The dkim_status ACL condition may now be used in data ACLs
- 8. Sqlite lookups accept a "file=<path>" option to specify a per-operation
- db file, replacing the previous prefix to the SQL string (which had
- issues when the SQL used tainted values).
+ 2. The dkim_verbose logging control also enables logging of signing
- 9. Lsearch lookups accept a "ret=full" option, to return both the portion
- of the line matching the key, and the remainder.
+ 3. The dkim_timestamps signing option now accepts zero to include a current
+ timestamp but no expiry timestamp. Code by Simon Arlott; testsuite
+ additions by jgh
-10. A command-line option to have a daemon not create a notifier socket.
+ 4. The recipients_max main option is now expanded
-11. Faster TLS startup. When various configuration options contain no
- expandable elements, the information can be preloaded and cached rather
- than the provious behaviour of always loading at startup time for every
- connection. This helps particularly for the CA bundle.
+ 5. Setting variables for "exim -be" can set a tainted value
-12. Proxy Protocol Timeout is configurable via "proxy_protocol_timeout"
- main config option.
+ 6. A dns:fail event
-13. Option "smtp_accept_msx_per_connection" is now expanded.
+ 7. The dsearch lookup supports search for a sub-path
-14. Log selector "queue_size_exclusive", enabled by default, to exclude the
- time taken for reception from QT log elements.
+ 8. Include mailtest utility for simple connection checking
-15. Main option "smtp_backlog_monitor", to set a level abve which listen
- socket backlogs are logged.
+ 9. Add SMTP WELLKNOWN extension
-16. Main option "hosts_require_helo", requiring HELO or EHLO before MAIL.
+ 10. Sqlite3 can be used for the hints databases (vs. DBD, NDB, GBDM, TDB).
+ Add "USE_SQLITE = y" and "DBMLIB = -lsqlite3" in Local/Makefile, to
+ override the settings done in the OS/Makefile-<platform> file
+
+Version 4.97
+------------
+
+ 1. The expansion-test facility (exim -be) can set variables.
+
+ 2. An event on a failing SMTP AUTH, for both client and server operations.
+
+ 3. Variable $sender_helo_verified with the result of an ACL "verify = helo".
+
+ 4. Predefined macros for expansion items, operators, conditions and variables.
+
+ 5. The smtp transport option "max_rcpt" is now expanded before use.
+
+ 6. The tls_eccurve option for OpenSSL now takes a list of group names.
+
+ 7. Queue runners for several queues can now be started from one daemon.
+
+ 8. New utility exim_msgdate converts message-ids to human readable format.
+
+ 9. An expansion operator for wrapping long header lines.
+
+ 10. A commandline option to print just the message IDs of the queue
+
+ 11. An option for the ${readsocket } expansion to set an SNI for TLS.
+
+ 12. The ACL remove_header modifier can take a pattern.
+
+ 13. Variable $recipients_list, a properly-quoted exim list.
+
+ 14. A log_selector for an incoming connection ID.
+
+Version 4.96
+------------
+
+ 1. A new ACL condition: seen. Records/tests a timestamp against a key.
+
+ 2. A variant of the "mask" expansion operator to give normalised IPv6.
+
+ 3. UTC output option for exim_dumpdb, exim_fixdb.
+
+ 4. An event for failing TLS connects to the daemon.
+
+ 5. The ACL "debug" control gains options "stop", "pretrigger" and "trigger".
+
+ 6. Query-style lookups are now checked for quoting, if the query string is
+ built using untrusted data ("tainted"). For now lack of quoting is merely
+ logged; a future release will upgrade this to an error.
+
+ 7. The expansion conditions match_<list-type> and inlist now set $value for
+ the expansion of the "true" result of the ${if}. With a static list, this
+ can be used for de-tainting.
+
+ 8. Recipient verify callouts now set $domain_data & $local_part_data, with
+ de-tainted values.

+ a non-smtp (eg. http) use. Options for customising.
+

-13. A main config option "allow_insecure_tainted_data" allows to turn
- taint errors into warnings.
Version 4.94
------------
9. There is a new ACL, specified by acl_smtp_notquit, which is run in most
cases when an SMTP session ends without sending QUIT. However, when Exim
- itself is is bad trouble, such as being unable to write to its log files,
+ itself is in bad trouble, such as being unable to write to its log files,
this ACL is not run, because it might try to do things (such as write to
log files) that make the situation even worse.
