v0.4.1

Released on June 24, 2022

Description: This release of SmartSim introduces a new experimental feature to help make SmartSim workflows more portable: the ability to run simulations models in a container via Singularity. This feature has been tested on a small number of platforms and we encourage users to provide feedback on its use.

We have also made improvements in a variety of areas: new utilities to load scripts and machine learning models into the database directly from SmartSim driver scripts and install-time choice to use either KeyDB or Redis for the Orchestrator. The RunSettings API is now more consistent across subclasses. Another key focus of this release was to aid new SmartSim users by including more extensive tutorials and improving the documentation. The docker image containing the SmartSim tutorials now also includes a tutorial on online training.
