      - The header file ``mjthread.h`` was removed along with the old engine threading API.

      - Moved island sparse matrix construction from :ref:`mj_island` (single threaded) into :ref:`mj_fwdConstraint`
        (multi-threaded). The island-specific matrices ``iM, iLD, iefc_J`` were removed from the arena and are now
        allocated on the stack.

      - Following the introduction of the :ref:`diagexact<option-flag-diagexact>` flag, the ``mjData`` field
        ``efc_diagApprox`` was renamed to ``efc_diagA``, as it can now be either the exact or approximate diagonal of
        the :math:`A` ("Delassus") matrix.
+     - The deprecated functions ``mju_{error,warning}_{i,s}`` have been removed.

    required ~500,000 ``mjtNum``'s, now only requires ~6000. Very large models can now load and run with the CG solver.
 #. Modified :ref:`mju_error` and :ref:`mju_warning` to be variadic functions (support for printf-like arguments). The

 #. Implemented a performant ``mju_sqrMatTDSparse`` function that doesn't require dense memory allocation.
 #. Added ``mj_stackAllocInt`` to get correct size for allocating ints on mjData stack. Reducing stack memory usage
    by 10% - 15%.
