+# Test installation of the latest version from PyPI works.
+# We make sure that we run the tests that apply to the version we installed,
+# rather than the latest tests in main.
+# The reason we do this, is that we want this workflow to test
+# that installing from PyPI/conda leads to a correct installation.
+# If we tested against main, the tests could fail
+# because the tests from main require the new features in main to pass.
