Old Python versions have reached end of life. It's about time to drop support for them.
Packages that are backports (for example, enum34) or known to be deprecated are not included (for example, distribute). If your package is incorrectly listed, please create a ticket.
This is not an official website, just a nice visual way to measure progress. To see the authoritative guide on wheels and other aspects of python packaging, see the Python Packaging User Guide.
Fantastic, a problem found is a problem fixed. Please create a ticket!
