We would also like to thank Lucas Estrada for his assistance in setting up the :ref:`ci-tests` on `Azure DevOps Pipelines `_ and for assistance with debugging. Shaddy Ahmed and Jennie Thomas helped us with the Matlab output of KPP. We thank Domenico Taraborrelli for providing the rosenbrock_posdef_h211b_qssa solver. Stuart Lacy wrote an export function for the `Master Chemical Mechanism `_. It creates KPP files that can be used out-of-the-box for the small model in the :file:`examples/mcm` directory. Simon Rosanka improved the :code:`Update_RCONST` subroutine by providing time-dependent concentration values via an optional parameter.
