Changes in synapse vx.x.x (x-x-x)
=================================
* Add support for registration fallback. This is a page hosted on the server
which allows a user to register for an account, regardless of what client
they are using (e.g. mobile devices).
* Application services can now poll on the CS API ``/events`` for their events,
by providing their application service ``access_token``.
Changes in synapse v0.7.1 (2015-02-19)
======================================

Upgrading to vx.xx
==================
Servers which use captchas will need to add their public key to::
static/client/register/register_config.js
window.matrixRegistrationConfig = {
recaptcha_public_key: "YOUR_PUBLIC_KEY"
};
This is required in order to support registration fallback (typically used on
mobile devices).
Upgrading to v0.7.0
