Support for non-x86 CPUs

pygmo 2.18.0 adds official support for non-x86 processors, specifically 64-bit ARM and PowerPC. Automated builds on these architectures have been added to the CI pipeline, courtesy of travis and circleci.

Serialisation changes

This release includes various changes in the serialisation of the main classes. As a result, it's not possible in pygmo 2.18.0 to unpickle from archives produced with earlier versions of pygmo.

Build system fixes & improvements

pygmo now requires CMake >= 3.17 when building from source. A compilation failure in debug mode with Python >= 3.9 has been fixed.

This is a minor release containing a few build system fixes, and bumping up the minimum required pybind11 version to 2.6.

As usual, the full changelog is available here:

The major new feature in this new pygmo release is an algorithm wrapper around the SciPy optimizers, developed by @mlooz

Additionally, like pagmo 2.16.0, pygmo now requires a C++17-capable compiler when installing from source.
