Release v2.2.2

The default setting for the create_session() method is to create a session with the media mode set
to relayed. In previous versions of the SDK, the default setting was to use the OpenTok Media Router
(media mode set to routed). In a relayed session, clients will attempt to send streams directly
between each other (peer-to-peer); if clients cannot connect due to firewall restrictions, the
session uses the OpenTok TURN server to relay audio-video streams.

Release v2.2.0

This version of the SDK includes support for working with OpenTok 2.0 archives. (This API does not
work with OpenTok 1.0 archives.)

Note also that the options parameter of the OpenTok.create_session() method has a media_mode
property instead of a p2p property.
