r0.1.0
======

This is the first release of the Identity Service API. With this API, clients and
homeservers can store bindings between third-party identifiers such as email addresses
and phone numbers, associating them with Matrix user IDs. Additionally, identity
servers offer the ability to invite third-party users to Matrix rooms by storing
the invite until the identifier is bound.
