MuJoCo 4.0.0 Released with Elasto-Plasticity, Split Python Packages, and Breaking Changes
4.0.0
Version 4.0.0 of MuJoCo, released on November 6, 2026, introduces elasto-plasticity for joints, tendons, and flexes, a speculative enable flag for contacts, and fourth-order accurate RK4 integration for ball and free joint orientations. The Python distribution is split into mujoco-core, mujoco-studio, and mujoco. Breaking changes include updated tendon semantics via side sites and revised elastic constants for non-interpolated flexes, requiring model migration.
