Isaac Lab 3.0 reaches general availability with Newton and kit-less workflows

SUMMARY

Isaac Lab 3.0 is now generally available, according to the release page in the isaac-sim/IsaacLab repository. The page calls this the official Isaac Lab 3.0 release and the recommended baseline for new projects and for migrations from Isaac Lab 2.x.

Isaac Lab 3.0 introduces a factory-based, multi-backend architecture. Assets, sensors, scenes and environments are backend-neutral and dispatch to whichever implementation is selected, so a supported task can switch physics, rendering or visualization without rewriting its logic. The release page adds that supported combinations remain task-specific. Newton, a Warp-native physics backend, offers MuJoCo-Warp, VBD and MPM solver paths. The release page also lists OV Libraries, which provide OVPhysX for PhysX and OVRTX for RTX rendering as standalone libraries. Isaac Sim is still available for workflows that need the full PhysX and RTX stack, the ROS bridge, XR, livestreaming or Kit tooling, but it is now fully optional.

On the data side, asset and sensor data use a ProxyArray type that gives zero-copy access to both Warp and PyTorch. A single isaaclab command handles training and playback across RSL-RL, RL-Games, skrl, Stable-Baselines3, RLinf and TorchRL. For deployment, the release lists LEAPP policy export, Isaac Capture teleoperation integration, and guidance for moving policies between PhysX and Newton in both directions.

The release targets Isaac Sim 6.2, Python 3.12, PyTorch 2.11 with CUDA 13.0, NVIDIA Warp 1.17, Newton 1.6.1 and RSL-RL 5.5.1. Migrating projects should note that quaternion order changes from (w, x, y, z) in Isaac Lab 2.x to (x, y, z, w), and the notes advise starting from a fresh Python 3.12 environment. A gallery of 17 browser demos, including a G1 velocity-control scene, runs Newton simulations on the CPU through WebAssembly.
