 	- some new functions to parse recursively dict keys and/or values that are faster than David's, but probably not as flexible. When these are all you need, they're more efficient.
 	- added a few new Jupyter notebooks
 
-feature/HPC:
-- added Slurm support
-- Fixed JSON load(s) to not convert to ASCII hence preserve UTF-8 and hopefully be faster.
-- Made sure file loads/saves use UTF-8
-- Fixed version dict to include units section and cleaned up a few other unit handlers
+* 0.9.3:
+- Changed the python version requirement to be 3.9+
+- Restructured the population grid object by splitting off functions that belong in the same category and storing them in a mixin-class within the population_extensions/ dir.
+- merged the HPC branch:
+	- added Condor support
