This release contains small improvements over PyO3 0.13.1. The minimum supported Rust version has been lowered to Rust 1.41. A serde feature has been added which provides implementations of Serialize and Deserialize for types inside the Py<T> smart pointer.
Of note is that this release disables automatic finalization of the Python interpreter at program exit for Rust binaries embedding the Python interpreter. This was found to cause a number of issues with C extensions such as Tensorflow and Scipy which were sensitive to the deinitialization order. For the vast majority of users this should cause no impact or fix a number of problem cases. For the minority who did depend on finalization, the unsafe method with_embedded_python_interpreter has been added to manually control the interpreter lifecycle.
For full details of all changes, see the CHANGELOG.
