 PP/22 Added -bw for inetd wait mode support.
 
+PP/23 Added PCRE_CONFIG=yes support to Makefile for using pcre-config to
+      locate the relevant includes and libraries.  Made this the default.
+
+PP/24 Fixed headers_only on smtp transports (was not sending trailing dot).
+      Bugzilla 1246, report and most of solution from Tomasz Kusy.
+
+JH/03 ${eval } now uses 64-bit and supports a "g" suffix (like to "k" and "m").
+      This may cause build issues on older platforms.
+
+PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
+      gnutls_priority_init, ignoring Exim options gnutls_require_kx,
+      gnutls_require_mac & gnutls_require_protocols (no longer supported).
+      Added SNI support via GnuTLS too.
+      Made ${randint:..} supplier available, if using not-too-old GnuTLS.
+
+PP/26 Added EXPERIMENTAL_OCSP for OpenSSL.
+
+PP/27 Applied dnsdb SPF support patch from Janne Snabb.
+      Applied second patch from Janne, implementing suggestion to default
+      multiple-strings-in-record handling to match SPF spec.
+
+JH/04 Added expansion variable $tod_epoch_l for a higher-precision time.
+
+PP/28 Fix DCC dcc_header content corruption (stack memory referenced,
+      read-only, out of scope).
+      Patch from Wolfgang Breyha, report from Stuart Northfield.
+
+PP/29 Fix three issues highlighted by clang analyser static analysis.
+      Only crash-plausible issue would require the Cambridge-specific
+      iplookup router and a misconfiguration.
+      Report from Marcin Mirosław.
+
+PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
+
+PP/31 %D in printf continues to cause issues (-Wformat=security), so for
+      now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
+      As part of this, removing so much warning spew let me fix some minor
+      real issues in debug logging.
+
+PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
+      assignment on my part.  Fixed.
+
+PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
+      of NSS, for GnuTLS/NSS interop.  Problem root cause diagnosis by
+      Janne Snabb (who went above and beyond: thank you).
+
+PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
+      string otherwise requires a connection and a bunch more work and it's
+      relatively easy to get wrong.  Should also expose TLS library linkage
+      problems.
+
+PP/35 Pull in <features.h> on Linux, for some portability edge-cases of
+      64-bit ${eval} (JH/03).
+
+PP/36 Define _GNU_SOURCE in exim.h; it's needed for some releases of
+      GNU libc to support some of the 64-bit stuff, should not lead to
+      conflicts.  Defined before os.h is pulled in, so if a given platform
+      needs to override this, it can.
+
+PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
+      protection layer was required, which is not implemented.
+      Bugzilla 1254, patch from Wolfgang Breyha.
+
+PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
+      into Exim, default to IKE id 23 from RFC 5114 (2048 bit).  Make
+      tls_dhparam take prime identifiers.  Also unbreak combination of
+      OpenSSL+DH_params+TLSSNI.
+
+PP/39 Disable SSLv2 by default in OpenSSL support.
+
+PP/40 Lower default size of EXIM_CLIENT_DH_MIN_BITS constant (used only by
+      GnuTLS at this time) from 1024 to 512.  Cautious folk can override
+      in Local/Makefile.
