+JH/06 Bug 1141: When operating a continued-connection transport, verify that
+ the interface option, if specified, evaluates to match the connection.
+ Previously, a queued message for the same host was sent without checking.
+
+JH/07 Bug 3106: Fix coding in SPA authenticator. A macro argument was not
+ properly parenthesized, resulting in a logic error. While the simple
+ fix was provided by Andrew Aitchison, the over-large code block resulting
+ from this macro made me want to replace it with a real function so more
+ extensive rework becamse needed.
+
+JH/08 The output of "exim -bV" now includes lookup types built as dynamic-load
+ modules.
+
+JH/09 Not a change, but worthy of note: There is no test coverage of the
+ heimdall-gssapi authenticator driver. It does build, though with (on at
+ least one platform) library version conflicts with the gsasl auth
+ driver). Confidence in its operation is lacking.
+
+JH/10 Bug 3108: On platforms not providing strchrnul() [OpenBSD] supply a proper
+ prototype (as well as implementaton). Previously, a return type "int"
+ was assumed, resulting in type-conversion bugs when int and pointer had
+ different size. This resulted in crashes while processing DKIM signatures
+ of received messages. Identification and fix from Qualys Security.
+
+JH/11 Lookups built as dynamic-load modules which support a single lookup
+ type are now only loaded if required by the config. Previously all lookup
+ modules present in the modules directory were loaded; this now applies
+ only to those supporting multiple types.
