  In this new version of ZMCintegral, we have added the functionality of
multi-function integrations, i.e. the ability to integrate more than $10^{3}$
different functions on GPUs. The Python API remains the similar as the previous
versions. For integrands less than 5 dimensions, it usually takes less than 10
minutes to finish the evaluation of $10^{3}$ integrations on one Tesla v100
card. The performance scales linearly with the increasing of the GPUs.
