Major Fix release

[IMPORTANT NOTE] An authentication bug was introduced in Go client 5.0.0. As a result, the client may fail to refresh its session token after it expires, requiring the client to be restarted. If you are using password-based authentication, we highly recommend that you upgrade your client to version 5.6.0+, which you can do safely.
