		^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
		.. deprecated:: 3.2.0
		Shared libraries have been deprecated in favor of pip-installable libraries.
		Shared libraries do not provide any functionality that can't already be achieved
		with pip requirements *and* as such don't provide much value in return for
		the added complexity.
		Known issues, especially those related to hot-reload, were not handled automatically
		for shared libraries, same as they are not handled for the libraries installed
		through pip.
