-JH/18 Convert macro handling to be tree-based, from the previous linear list.
-      With the number of builtin macros we now have this is worthwhile,
-      dropping the config-file read time (during which new macros are checked
-      and registered, and macros are expanded) from about 500 usec to about 180.
+JH/18 Bug 2239: Enforce non-usability of control=utf8_downconvert in the mail
+      ACL.  Previously, a crash would result.
+
+JH/19 Speed up macro lookups during configuration file read, by skipping non-
+      macro text after a replacement (previously it was only once per line) and
+      by skipping builtin macros when searching for an uppercase lead character.
+
+JH/20 DANE support moved from Experimental to mainline.  The Makefile control
+      for the build is renamed.
+
+JH/21 Fix memory leak during multi-message connections using STARTTLS.  A buffer
+      was allocated for every new TLS startup, meaning one per message.  Fix
+      by only allocating once (OpenSSL) or freeing on TLS-close (GnuTLS).
