+  - Fixed a memory leak when resizing the connection pool and realloc()
+    failed. Now we don't fall back to malloc(), which should be sane anyway.
+    Patch from Florian Westphal, .
   - Added support for the Howl (http://www.porchdogsoft.com/products/howl/)
     Rendezvous API, in addition to the API of Apple (Mac OS X). The available
     APU will be autodetected when you call "./configure --with-rendezvous".
