Installation and License Keys
Basic installation and upgrades from PyPI hasn't changed from PySimpleGUI 4 to PySimpleGUI 5. Major releases of PySimpleGUI are distributed through PyPI. PyPI is the official distribution point for PySimpleGUI 5 releases. A new addition to PySimpleGUI 5 is license keys.
To install or upgrade from PyPI, like all Python packages,
pip is used. License keys are part of the installation process, after pip has installed PySimpleGUI.
