This initial Alpha release fixes an information disclosure issue, and should be considered a Security release.
When a message is posted to Matrix, if there is any kind of error or problem with the request, Guzzle throws an exception with the URL of the request -- e.g. if there's a 502 Gateway timeout. If this happens, Guzzle includes the access_token in the exception.
This might get revealed to a caller -- for example, when a JSONAPI request creates an entity and triggers this error, the Matrix user's access_token is sent back to the caller in the exception.
Initial release. Has admin page for setting an account, generates an access_token from username/pw, and creates a MatrixClient service that can be used for generic posts to the Matrix API as well as specific support for Sync, Join Room, Send Message.
