What changed
- Leaner installs: pip install now only grabs core features; training and dataset extras must be explicitly requested to avoid bloat and conflicts.
- Modular RL stack: The reinforcement learning code is fully decoupled into swappable blocks, letting you replace specific networks without touching the rest.
- Smarter default model: The built-in GR00T embodied AI model upgrades from N1.5 to N1.7, offering better action generalization for robots.
- Higher PyTorch requirement: Minimum PyTorch version bumped to 2.7 to leverage faster CUDA kernels and improved autograd.
- Cleaner imports: Internal paths are cleaned up; users should stick to stable public entry points to ensure future compatibility.
