Cross-product compatibility

Use this matrix to select Newton, ROS workspaces, Isaac ROS, and Isaac Lab for your Isaac Sim release. Matching a release number alone does not establish compatibility for every physics backend, policy, or custom ROS interface. Hardware and driver requirements are listed separately in Isaac Sim Requirements.

Version selection matrix

Component	Isaac Sim 6.1.0	Isaac Sim 6.2.0	Reference
Newton runtime	Newton 1.5.0, as listed in the 6.1.0 release notes.	Bundled Newton 1.6.1 and MuJoCo / MuJoCo Warp 3.12.0.	Newton Physics Backend.
ROS workspace	Published workspace release IsaacSim-6.1.0.	Use the matching workspace release IsaacSim-6.2.0.	ROS workspace releases; Build the ROS workspace.
Isaac ROS	See the Isaac ROS compatibility table.	See the Isaac ROS compatibility table.	Isaac ROS release notes.
Isaac Lab	Supports Isaac Lab v3.0.0-EA.	Supports Isaac Lab v3.0.0-GA.	Isaac Lab version dependency table.

For Isaac ROS, use only pairings explicitly listed in its compatibility table; do not infer support for unlisted releases.

Do not substitute the ROS workspace repository’s default branch and assume compatibility. Custom ROS interfaces must match the ROS distribution and Python version described in ROS 2 installation.

Keep the bundled Newton dependencies together instead of upgrading Newton independently in the simulator’s Python environment. For Isaac Lab policies, follow the policy’s documented simulator and physics-backend requirements; a simulator pairing does not guarantee that a policy trained with another backend will behave identically.
