+# NOTE: For the 6.6.3.1 release, we specifically download the wheels from
+# https://download.qt.io/snapshots/ci/pyside/6.6.3.1/RC2, instead of
+# https://download.qt.io/official_releases/QtForPython/pyside6. The reason is
+# that these wheels are somehow missing from the official page. Still, the
+# hashes match those in PyPI, so this place is as good as any.
