Technical details
Newton v1.5.0 (released 2026-08-11) is a feature release of the open-source Newton physics engine aimed at scalable batched simulation for robot learning. It adds an experimental newton.controllers module with vectorized joint-space impedance control for heterogeneous GPU robot batches, isolated implicit MPM, masked solver resets and per-world gravity for multi-world workflows, and opt-in MuJoCo Warp sleeping. Contact handling is more reproducible (deterministic hydroelastic generation, stable box manifolds), cables gain independent stretch/shear/bend/twist, and USD/MJCF import fidelity improves. Code is Apache-2.0.
