`tmrl` 0.4.0 introduces network security and many changes to the API.
In particular:
- network security is now handled by [tlspyo](https://github.com/MISTLab/tls-python-object)
- the API is now compatible with any framework (i.e., we do not force the use of PyTorch anymore)
- the framework now supports color images
- the default `config.json` file is tuned for fast training of CNN (grayscale) policies
`tmrl` 0.4.0 also "officially" launches the first Beta of the [TrackMania Roborace League](https://github.com/trackmania-rl/tmrl/blob/master/readme/competition.md) competition.
The [competition tutorial script](https://github.com/trackmania-rl/tmrl/blob/master/tmrl/tuto/competition/custom_actor_module.py) is particularly useful for ML developers who desire to code advanced training pipelines in TrackMania.
