v1.1 is the same as v1.0. (Version 1.0 did not build correctly)
Differences from the pre-1.0 dev version:
* Creates its own table instead of stuffing things into the 'data' column in the users table
* New login token format -- now uses a shared secret (password) to verify tokens instead of relying on access to the shared_users table. This should make it easier to use as a SSO solution with other platforms and Drupal installs running on separate servers
