+ - Issue #10513: Fix a regression in Connection.commit().  Statements should
+   not be reset after a commit.
+ 
 +- Issue #12319: Chunked transfer encoding support added to
 +  http.client.HTTPConnection requests.  The
 +  urllib.request.AbstractHTTPHandler class does not enforce a Content-Length
 +  header any more.  If a HTTP request has a non-empty body, but no
 +  Content-Length header, and the content length cannot be determined
 +  up front, rather than throwing an error, the library now falls back
 +  to use chunked transfer encoding.
