+Version 4.95
+------------
+
+ 1. The fast-ramp two phase queue run support, previously experimental, is
+ now supported by default.
+
+ 2. The native SRS support, previously experimental, is now supported. It is
+ not built unless specified in the Local/Makefile.
+
+ 3. TLS resumption support, previously experimental, is now supported and
+ included in default builds.
+
+ 4. Single-key LMDB lookups, previously experimental, are now supported.
+ The support is not built unless specified in the Local/Makefile.
+
+ 5. Option "message_linelength_limit" on the smtp transport to enforce (by
+ default) the RFC 998 character limit.
+
+ 6. An option to ignore the cache on a lookup.
+
+ 7. Quota checking during reception (i.e. at SMTP time) for appendfile-
+ transport-managed quotas.
+
+ 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).
+
+ 9. Lsearch lookups accept a "ret=full" option, to return both the portion
+ of the line matching the key, and the remainder.
+
+10. A command-line option to have a daemon not create a notifier socket.
+
+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.
+
+12. Proxy Protocol Timeout is configurable via "proxy_protocol_timeout"
+ main config option.
+
+Version 4.94
+------------
+
+ 1. EXPERIMENTAL_SRS_NATIVE optional build feature. See the experimental.spec
+ file.
+
+ 2. Channel-binding for authenticators is now supported under OpenSSL.
+ Previously it was GnuTLS-only.
+
+ 3. A msg:defer event.
+
+ 4. Client-side support in the gsasl authenticator. Tested against the
+ plaintext driver for PLAIN; only against itself for SCRAM-SHA-1 and
+ SCRAM-SHA-1-PLUS methods.
+
+ 5. Server-side support in the gsasl authenticator for encrypted passwords, as
+ an alternate for the existing plaintext.
+
+ 6. Variable $local_part_data now also set by router check_local_user option,
+ with an de-tainted version of $local_part.
+
+ 7. Named-list definitions can now be prefixed "hide" so that "-bP" commands do
+ not output the content. Previously this could only be done on options.
+
+ 8. As an experimental feature, the dovecot authentication driver supports inet
+ sockets. Previously it was unix-domain sockets only.
+
+ 9. The ACL control "queue_only" can also be spelled "queue", and now takes an
+ option "first_pass_route" to do the same as a "-odqs" on the command line.
+
+10. Items specified for the router and transport headers_remove option can use
+ a trailing asterisk to specify globbing.
+
+11. New $queue_size variable.
+
+12. New variables $local_part_{pre,suf}fix_v.
+
+13. New main option "sqlite_dbfile", for use in preference to prefixing the
+ lookup string. The older method fails when tainted variables are used
+ in the lookup, as the filename becomes tainted. The new method keeps the
+ filename separate.
+
+14. Options on the dsearch lookup, to return the full path and to filter
+ filetypes for matching.
+
+15. Options on pgsql and mysql lookups, to specify server separate from the
+ lookup string.
+
+16. An option on all single-key lookups, to return (on a hit) a de-tainted
+ version of the lookup key rather than the looked-up data.
+
+17. $domain_data and $local_part_data are now set by all list-match successes.
+ Previously only list items that performed lookups did so.
+ Also, matching list items that are tail-match or RE-match now set the
+ numeric variables $0 (etc) in the same way os other RE matches.
+
+18. Expansion item ${listquote {<char} {<item>}}.
+
+19. An option for the ${readsocket {}{}{}} expansion to make the result data
+ cacheable.
+
+20. dkim_verify_min_keysizes, a list of minimum acceptable public-key sizes.
+
+21. bounce_message_file and warn_message_file are now expanded before use.
+
+22. New main config option spf_smtp_comment_template to customise the
+ $spf_smtp_comment variable
+
+
+
Version 4.93
------------
11. Main options for DKIM verify to filter hash and key types.
-12. Under GnuTLS, with TLS1.3, support for full-chain OCSP stapling.
+12. With TLS1.3, support for full-chain OCSP stapling.
13. Dual-certificate stacks on servers now support OCSP stapling, under OpenSSL.
15: Support under OpenSSL for writing NSS-style key files for packet-capture
decode. The environment variable SSLKEYLOGFILE is used; if an absolute path
it must indicate a file under the spool directory; if relative the the spool
- directory is prepended. Works on the server side only. Support under
+ directory is prepended. Works on the server side only. Support under
GnuTLS was already there, being done purely by the library (server side
only, and exim must be run as root).
+16: Command-line option to move messages from one named queue to another.
+
+17. Variables $tls_in_ver, $tls_out_ver.
+
Version 4.92
--------------
14. Main option "dns_trust_aa" for trusting your local nameserver at the
same level as DNSSEC.
