OpenBSD 5.5. Detect this OpenBSD version and skip calling this
function when detected.
+JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
+ cause callback expansion.
+
+TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
+ syntax errors in an expansion can be treated as a string instead of
+ logging or causing an error, due to the internal use of bool_lax
+ instead of bool when processing it.
+
+JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
+ server certificates when making smtp deliveries.
+
+JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.
+
+JH/04 Add ${sort {list}{condition}{extractor}} expansion item.
+
+TL/04 Bugzilla 1216: Add -M (related messages) option to exigrep.
+
+TL/05 GitHub Issue 18: Adjust logic testing for true/false in redis lookups.
+ Merged patch from Sebastian Wiedenroth.
+
+JH/05 Fix results-pipe from transport process. Several recipients, combined
+ with certificate use, exposed issues where response data items split
+ over buffer boundaries were not parsed properly. This eventually
+ resulted in duplicates being sent. This issue only became common enough
+ to notice due to the introduction of conection certificate information,
+ the item size being so much larger. Found and fixed by Wolfgang Breyha.
+
+JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
+ size buffer was used, resulting in syntax errors when an expansion
+ exceeded it.
+
+JH/07 Add support for directories of certificates when compiled with a GnuTLS
+ version 3.3.6 or later.
