• More portable architecture detection (inspired by the discussion https://discuss.ocaml.org/t/a-zoo-of-values-for-system/8525 initiated by Olaf Hering, with helpful comments from Daniel Bünzli, @EduardoRFS, David Allsopp, kit-ty-kate and jbeckford)

• Better compatibility with Windows

• Correct version detection for Python 3.10

• Use dune as default build system (dunification done by Laurent Mazare, https://github.com/thierry-martinez/pyml/pull/28)

  This should in particular fix build problems of reverse dependencies with the byte-code compiler (reported by @nicoTolly, https://github.com/thierry-martinez/pyml/issues/62)

  • Handle more platforms with dune (reported by Olaf Hering, https://github.com/thierry-martinez/pyml/issues/68)

  • pyutils is no longer used by generate and is shipped with pyml package as it was the case with Makefile-based build system (reported by Olaf Hering, https://github.com/thierry-martinez/pyml/issues/69)

• Support for raising exceptions with traceback from OCaml (implemented by Laurent Mazare, https://github.com/thierry-martinez/pyml/pull/65)

• Fix soundness bug with numpy (reported by Richard Alligier, https://github.com/thierry-martinez/pyml/pull/65)

• Fix Py.Array.numpy arrays on 32-bit platforms (reported by Olaf Hering, https://github.com/thierry-martinez/pyml/pull/70)

• Fix soundness bug on strings with OCaml <4.06 (reported by OCaml CI)

2021-02-26

• Compatibility with Python 3.10 (reported by Richard W.M. Jones)

• Add Py.Set module for Python sets. (Added by Laurent Mazare, https://github.com/thierry-martinez/pyml/pull/58)

• Fix #61: Numpy.to_bigarray raises an exception if source value is not a Numpy array instead of segfaulting. (Reported by Jonathan Laurent, https://github.com/thierry-martinez/pyml/issues/61)

• Fix #56, #59: Add python-config heuristics to find Python library. (Reported by Anders Thuné and Nils Becker, https://github.com/thierry-martinez/pyml/issues/56 https://github.com/thierry-martinez/pyml/issues/59)
