ANN: SIP v6.0.2, PyQt-builder v1.9.0, PyQt v5.15.3 and PyQt v6.0.2 Released

[Eric Larson]

I have a problem with 5.13.32 on Ubuntu 20.10 x86_64 installation via pip
after upgrading:

$ python -c "from PyQt5.QtWidgets import QApplication, QWidget; app =
QApplication([])"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15'
not found (required by
/home/larsoner/.local/lib/python3.9/site-packages/PyQt5/QtWidgets.abi3.so)

Similar error on CircleCI
<https://app.circleci.com/pipelines/github/mne-tools/mne-python/6435/workflows/9c93b654-5a25-4b5b-a0d4-1a0eeba1c70f/jobs/25378>
which
uses pip:

ImportError: libQt5Widgets.so.5: cannot open shared object file: No such
file or directory

Do I need to update my projects to depend on the Qt libraries in addition
to PyQt5 now? This seems like a backward compat break as `pip install
pyqt5` will no longer "just work" for people.
