0.50.0

This release includes probably the biggest change of any of the releases so far: We introduced backends to separate the compilation-specific parts from the general structure of the package. This makes numba in principle an optional dependency of the package, and it will hopefully allow us to implement other backends in the future.

Since this major refactoring breaks some interfaces, we also used the opportunity to adjust some APIs. At the same time we removed support for Python 3.9.

• Introduced backends by @david-zwicker in #737
• Removed support for Python 3.9 by @david-zwicker in #738
