R2018b release notes has "batchsim"... how is this different than Parallel Computing Toolbox?

batchsim: allows you to run batch simulations, in serial or in parallel. To run batch simulations in parallel, specify the size of the parallel pool. batchsim offloads simulations to the compute cluster, giving you the ability to carry out other tasks while the batch job is processing, or close the client MATLAB and access the batch job later.

Is this something new? Is this different from the Parallel Computing Toolbox?

batchsim is new in R2018b, and is designed to work with Parallel Computing Toolbox to make it simpler to run multiple Simulink simulations in parallel in a "batch" offload mode.

batchsim is the "offload" version of parsim - meaning that you don't need to create use a parallel pool, and you can e.g. quit your client MATLAB while your simulations are running in the background.
