[ANN] Windows-friendly OCaml 4.12 distribution 2nd preview release (0.2.0)

0.2.3 0.2.2 is now released.

Some of the bigger changes:

  • (Bug Fixes) Many problems with Visual Studio have been resolved, especially for non-English installations.
  • (Features) Pre-alpha support for macOS and Windows 32-bit, in addition to the existing Windows 64-bit support.
  • (Reliability) There is now an internal GitHub Actions CI system that builds Windows 32-bit, Windows 64-bit and macOS (x64). In the future GitHub Actions will be offered to anyone who needs to test their own 32-bit and 64-bit Windows packages.
  • (Reliability) The Windows MinGW Opam repository vended by fdopen is still used but has been drastically pruned. Now the thousands of MinGW and DKML (MSVC) patches are pinned, and those pinned package versions are tested with the GitHub Actions CI system.

The v0.2.3 release notes has upgrade instructions and a detailed list of changes.
