First release of mjbatch: a Python library for running thousands of MuJoCo simulations in parallel on CPU.

pip install mjbatch

• Steps N simulations on a C++ thread pool with the GIL released
• Live NumPy views of state and controls across the batch
• Per-simulation model parameters, with set_const to recompute derived constants
• Wheels for Linux (x86_64, aarch64) and macOS (arm64), Python 3.10–3.14 and free-threaded 3.14t; requires mujoco 3.11.0
