@@ -218,6 +218,20 @@ JH/45 Use a (new) separate store pool-pair for DKIM verify working data.
       This meant a connection with many messages would use continually-growing
       memory.
 
+JH/46 Use an exponentially-increasing block size when malloc'ing store.  Do it
+      per-pool so as not to waste too much space.  Previously a constant size
+      was used which resulted in O(n^2) behaviour; now we get O(n log n) making
+      DOS attacks harder.  The cost is wasted memory use in the larger blocks.
+
+JH/47 Use explicit alloc/free for DNS lookup workspace.  This permits using the
+      same space repeatedly, and a smaller process footprint.
+
+JH/48 Use a less bogus-looking filename for a temporary used for DH-parameters
+      for GnuTLS.  Previously the name started "%s" which, while not a bug,
+      looked as if if might be one.
