- `qLDiagSqrtInv` is only required for the dual solvers. It is now computed as-needed rather than unconditionally. - `mj_solveM2` now requires a new input array `sqrtInvD` which contains the square root of the inverse diagonal D (formerly saved in `qLDiagSqrtInv`).

MuJoCo XLA (MJX)
This package is a re-implementation of the MuJoCo physics engine in JAX. This library is developed and maintained by Google DeepMind, and is kept up-to-date with the latest developments in MuJoCo itself.
The mujoco-mjx package is API-compatible with MuJoCo, but is missing some
features found in MuJoCo. See our
documentation for more
details concerning feature parity.
Installation
The recommended way to install this package is via PyPI:
pip install mujoco-mjx
Usage
Once installed, the package can be imported via from mujoco import mjx. Please
consult our documentation
for further detail on the package's API.
We recommend going through the tutorial notebook which introduces the MJX API
and trains a reinforcement learning policy in a few minutes: 
Versioning
The major.minor.micro portion of the version number matches the version of
MuJoCo that this library provides. Optionally, if we release updates to MJX that
target the same version of MuJoCo, a .postN suffix is added, for example
3.0.1.post2 represents the second update to MJX for MuJoCo 3.0.1.
