tornado.curl_httpclient

• Improved debug logging on Python 3.

tornado.httpserver

• Content-Length and Transfer-Encoding headers are no longer sent with 1xx or 204 responses (this was already true of 304 responses).
• Reading chunked requests no longer leaves the connection in a broken state.

tornado.iostream

• Writing a memoryview can no longer result in “BufferError: Existing exports of data: object cannot be re-sized”.

tornado.options

• Duplicate option names are now detected properly whether they use hyphens or underscores.

tornado.testing

• AsyncHTTPTestCase.fetch now uses 127.0.0.1 instead of localhost, improving compatibility with systems that have partially-working ipv6 stacks.

tornado.web

• It is no longer allowed to send a body with 1xx or 204 responses.

tornado.websocket

• Requests with invalid websocket headers now get a response with status code 400 instead of a closed connection.
