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 previous 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.
13. Option "smtp_accept_max_per_connection" is now expanded.
14. Log selector "queue_size_exclusive", enabled by default, to exclude the
time taken for reception from QT log elements.
15. Main option "smtp_backlog_monitor", to set a level above which listen
socket backlogs are logged.
16. Main option "hosts_require_helo", requiring HELO or EHLO before MAIL.
17. A main config option "allow_insecure_tainted_data" allows to turn
18. TLS ALPN handling. By default, refuse TLS connections that try to specify
a non-smtp (eg. http) use. Options for customising.
19. Support for MacOS (darwin) has been dropped.
