Latest versions for Freq domain EM casing modeling

I currently use the following:

git clone GitHub - simpeg-research/heagy-2021-tle-casing
conda init
conda env create -f environment.yml
conda activate heagy-2021-tle-casing
pip uninstall empymod
pip install empymod==2.2.0
pip install --upgrade simpeg==0.21.1

can anyone tell me what the most up to date modules are? Am I useing incompatible or old modules?

thanks for your help.
Mike
