-JH/02 Add transaction support for hintsdbs. The sole initial provider is
- sqlite, and is used for the wait-transport and retry DBs. Transactions
- imply locking internal to the DB. We no longer need a separate lockfile,
- can keep the DB handle open for extended periods, yet potentially benefit
- from concurrency on non-conflicting record uses.
+JH/05 Fix hintsdb support for dbmjz when compiled using sqlite3. Previously
+ the backend support assumed keys would be simple C strings, but dbmjz
+ uses keys with embedded NUL bytes. The builtin hintsdb use is unaffected,
+ but installations using dbmjz will need to rebuild those DBs.
+
+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.
