I tried upgrading from 1.1.0-Alpha1 to 1.2.0.Beta1.jar.  I get many errors that look like this:

[org.keycloak.protocol.oidc.endpoints.AuthorizationEndpoint] (default task-122) Invoking deprecated endpoint http://localhost:8080/auth/realms/abecorn/tokens/login?client_id=trade-client&redirect_uri=http%3A%2F%2Flocalhost%3A9001%2F%3Fredirect_fragment%3D%252F&state=150ce43d-1f7e-4462-8156-c3fbb5dcd92b&response_type=code
18:35:32,990 ERROR [io.undertow.request] (default task-122) UT005023: Exception handling request to /auth/realms/abecorn/tokens/login

Also,  I had to copy the themes folder from the dist appliance because the war distributable is missing the themes folder.
