BETSEE 0.8.2.0 (Kindest Kaufmann) released. Significant changes include: * Setuptools-based installation sanitized. PySide2 is no longer erroneously required at pre-installation time, thus resolving a significant blocker for distribution by PyPI and conda-forge. * Startup dependency validation sanitized. The application startup process now validates the satisfiability (i.e., the importability and sufficient version) of BETSE only once rather than twice, thus resolving discrepancies between setuptools-specific versioning for BETSE and the actual physical version of BETSE on developer machines. * Startup errors displayed graphically. Fatal exceptions raised on startup are now embedded within a PySide2-based message box.
