Packaging History






  • pipenv-based application dependency management tutorial added to PyPUG.

  • MOSS grant for PyPI awarded to PSF, team began in December to focus on replacing legacy PyPI.

  • PEP 517 accepted ( build system backends).

  • Legacy upload API switched off.



  • pip (v7) started caching built wheels, and installing from them, instead of installing directly from sdists (pip release notes).

  • pip (v7) started supporting --install-option and --global-option per requirement in requirement files (pip release notes).

  • setuptools (v18.3) now allows disabling of the manipulation of the sys.path during the processing of the easy-install.pth file.

  • PEP 470, which deprecated external, non-PyPI hosting, was accepted.

  • PEP 508 published to standardise the specification format for individual dependencies.



Before 2013

2012-06-19: The effort to include “Distutils2/Packaging” in Python 3.3 was abandoned due lack of involvement. [6]

2011-02-28: The Python Packaging Authority (PyPA) is created to take over the maintenance of pip and virtualenv from Ian Bicking, led by Carl Meyer, Brian Rosner and Jannis Leidel. Other proposed names were “ianb-ng”, “cabal”, “pack” and “Ministry of Installation”.

2008: distribute was forked from setuptools by Tarek Ziade, in an effort to create a more open project.

2008: pip was introduced by Ian Bicking as an alternative to easy_install (the installer included with setuptools)

2007: virtualenv was introduced by Ian Bicking, which allowed users to create isolated Python environments based on a central system installation of Python.

2006: buildout was introduced by Jim Fulton, with the goal to create a system for repeatable installations of potentially complex projects.

2005: Package files could be hosted on PyPI for the first time, following the sprints at PyCon US 2005.

2004: setuptools was introduced by Phillip Eby, which included the Egg <pypug:Egg> format, and the ability to declare and automatically install dependencies.

2003: PyPI was up and running.

2002: Richard Jones started work on PyPI, and created PEP 301 to describe it.

2001: PEP 241 was written to standardize the metadata for distributions.

2000: catalog-sig was created to discuss creating a centralized index of distributions.

2000: distutils was added to the Python standard library in Python 1.6.

1998: The distutils-sig dicussion list was created to discuss the development of distutils.
