PP/01 Handle short writes when writing local log-files.
non-compliant senders.
Analysis and variant patch by Todd Lyons.
-NM/04 Bugzilla 1237 - fix cases where printf format usage no indicated
+NM/04 Bugzilla 1237 - fix cases where printf format usage not indicated
Bug report from Lars Müller <lars@samba.org> (via SUSE),
Patch from Dirk Mueller <dmueller@suse.com>
JH/01 Bugzilla 660 - Multi-valued attributes from ldap now parseable as a
comma-sep list; embedded commas doubled.
+JH/02 Refactored ACL "verify =" logic to table-driven dispatch.
+
PP/15 LDAP: Check for errors of TLS initialisation, to give correct
diagnostics.
Report and patch from Dmitry Banschikov.
PP/24 Fixed headers_only on smtp transports (was not sending trailing dot).
Bugzilla 1246, report and most of solution from Tomasz Kusy.
-JH/02 ${eval } now uses 64-bit and supports a "g" suffix (like to "k" and "m").
+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.
Exim version 4.77
