PyWPS (any version) supports the OGC WPS 1.0.0 standard.
PyWPS < 4 does not currently support 2.0.0 version.
PyWPS 4 will support OGC:WPS 2.0.0 and contains partial features in support of OGC WPS 2.0.0.
PyWPS-4 is a complete rewrite in support of the OGC WPS standard. It has a completely different codebase compared to previous (3.x) versions.
PyWPS-4 supports both Python 2.x and Python 3.x versions. It uses Flask, lxml and other modern libraries for web application development. The processes are not backwards compatible, but the code should be easy to port (the philosophy remains the same).
As a general rule, use the latest stable version. Older versions (1.0.0, 2.0.x) are no longer supported.
Current stable means PyWPS 3.2 or the master branch in the PyWPS repository.
PyWPS-4 is under heavy development, the OGC WPS standard is not fully implemented yet.

Of course, there is Documentation, but it does not contain modules documentation yet. To get this, try:
