Dual-certificate stacks on servers now support OCSP stapling, under GnuTLS + version 3.5.6 or later. + + 2. DANE is now supported under GnuTLS version 3.0.0 or later. Both GnuTLS and + OpenSSL versions are moved to mainline support from Experimental. + New SMTP transport option "dane_require_tls_ciphers". + + 3. Feature macros for the compiled-in set of malware scanner interfaces. + + 4. SPF support is promoted from Experimental to mainline status. The template + src/EDITME makefile does not enable its inclusion. + + 5. Logging control for DKIM verification. The existing DKIM log line is + controlled by a "dkim_verbose" selector which is _not_ enabled by default. + A new tag "DKIM=" is added to <= lines by default, controlled by + a "dkim" log_selector. + + 6.

DKIM operations can now use the Ed25519 algorithm in addition to RSA, under + GnuTLS 3.6.0 or OpenSSL 1.1.1 or later. + +10. Builtin feature-macros _CRYPTO_HASH_SHA3 and _CRYPTO_SIGN_ED25519, library + version dependent. + +11. "exim -bP macro " returns caller-usable status. + +12.

If the cluster has master/slave replication, the + list must contain all the master and slave servers. + +16. Add an option to the Avast scanner interface: "pass_unscanned".

Optionally, an alternate format for spool data-files which matches the + wire format - meaning more efficient reception and transmission (at the + cost of difficulty with standard Unix tools).
