This release mainly adds support for recording live timing data and using it as a data sources.
(consider this beta functionality)
Additionally, timing data is now loaded without telemetry by default when calling Session.load_laps.
Telemetry data is usually not available anymore. Therefore, this prevents a confusing error.
You will need to record live timing data during a session if you want to have access to telemetry data.
(At least it looks like that. Whether this will change again, I don't know.)
