Change log file for Exim from version 4.21
-------------------------------------------
-Exim version 4.78
+Exim version 4.80
-----------------
PP/01 Handle short writes when writing local log-files.
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
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).
