This release adds support for installing pure-Python sdists. This means that all pure-Python packages on PyPI should now work with Chaquopy, whether they have wheels available or not. If you have any difficulty installing a package, please report it at our issue tracker.

Other changes:

• The Python major version of buildPython is now required to be the same as that of the app itself when using pip, and the default value of buildPython has been changed accordingly.
• Fix imp.find_module and imp.load_module.
• Implement implicit namespace packages on Python 3 (PEP 420).
• Add partial support for .pth files. Only the execution of lines starting with import is currently implemented: all other lines are ignored.
• Add message explaining how to show full pip output in Android Studio 3.1’s new Build window.
• Fix “registering invalid inputs” warning in Android Studio 3.1.
