This release marks a milestone in terms of operating system support:

  - Support for platforms missing some functions in the C library
  - Solaris and derivates are supported (tested on illumos/OpenIndiana)
  - macOS is supported
  - Windows is supported

Although not all platforms received the same level of testing on all
supported Python versions, this release is a big improvement in terms
of platform support. All the MADV_* constants are exposed on the
supported platforms, and generally .find() and .rfind() is faster or
comparable to the performance of the built-in functions. In several
cases it is already significantly faster.

The supported platforms now include:

  - Linux
  - BSD systems (FreeBSD, NetBSD, OpenBSD)
  - SunOS/Solaris (illumos/OpenIndiana)
  - macOS
  - Windows
