+* Database: better validation of on-disk stored data
+* Database: minor optimizations and reliability improvements
+* -loadblock=FILE will import an external block file
+
+
+JSON-RPC API
+------------
+* Internal HTTP server is now thread-per-connection, rather than
+  a single-threaded queue that would stall on network I/O.
+* Internal HTTP server supports HTTP/1.1, pipelined requests and
+  connection keep-alive.
+* Support JSON-RPC 2.0 batches, to encapsulate multiple JSON-RPC requests
+  within a single HTTP request.

+* Added 'getrawmempool', to list contents of TX memory pool
