This release builds on the version 2.1 series by:

• Updating, and fixing bugs in, plasmasphere models
• Modernizing the CatLog script for merging/concatenating log files
• Updating the documentation
• Modernizing and updating index retrieval scripts, and updating RamIndices data file
• Building capability for transitioning RAM-SCB to runs-on-request at NASA's Community Coordinated Modeling Center
• Ensuring that the CCMC runs-on-request Docker container can also be built and run locally
• Developing canned summary plot routines (primarily based on SpacePy library routines)
• Enabling the convenience routines developed for runs-on-request to be used outside of the Docker workflow
• Fixing several small issues

This minor release builds on version 2.1.0 by:

• Streamlining the build system
• Updating the documentation to remove and replace out-of-date descriptions and directions
• Updating functional/regression testing and added new unit-testing framework
• Providing support for GCC/gfortran version >= 10
• Adding new ion loss mechanisms via EMIC scattering and field line curvature scattering
• Updating VTK visualization tools
• Updating plasmasphere model implementations and coulomb collision losses
• Fixing numerous small bugs
• Adding citation data directly to the repository

This release provides significant numerical upgrades from the version 2.0 release.

Some upgrades include:

• SCB has increased robustness and more flexibly fits highly distorted stormtime fields (due to improved handling of the outer bounadry and convergence methods)
• The code now treats the magnetopause inside its domain physically.
• A self-consistent electric field calculation has been added as an option.
• Coupling to recent versions of SWMF has been (re)implemented, with only minor updates pending.
• Library dependencies have changed for better performance and easier installation.
• More flexibility in setup can be obtained. Timesteps and resolutions are configurable, etc.
• Each species is now calculated in parallel (OpenMP)
