PyPI beta announcement
[This page is a draft and not to be used/publicized until we close out the "publicize beta" milestone. That'll probably be by March 25, 2018.]
The new Python Package Index is now in beta at https://pypi.org/. On the Warehouse roadmap, it looks like the full switch will happen sometime in April 2018, so here's a heads-up about why we're switching, what's changed, and what to expect. To get an email when the new site replaces the old one, please sign up for the low-traffic PyPI announcements email list.
The legacy PyPI site at https://pypi.python.org started in the early 2000s. In recent years, users faced outages, malicious packages, and spam attacks, and the legacy codebase made it hard to maintain and even harder to develop new features.
The new PyPI (Warehouse) has a far more modern look, and is up-to-date under the hood as well; a proper web framework (Pyramid), 100% backend test coverage, and a Docker-based development environment make it easier for current and new developers to maintain it and add features.
Thanks to Mozilla's Open Source Support funding, developers have added many new features, overhauled infrastructure, and made steady progress towards redirecting traffic to the new site and shutting down the old one. The full switch will include redirecting browser and pip install traffic from the old site; then, sometime in late April or early May, the legacy site will be entirely shut down.
You may not need to change anything right away. Thanks to redirects, your sites, services, and tools will probably be able to seamlessly switch to the new site. We have a migration guide for package users and maintainers and a migration guide for API users. If you're affected by one of the deprecations below, you should adapt and migrate by early April 2018. Sign up for the low-traffic PyPI announcements email list to get a heads-up when we have a more precise date.
New PyPI Features
- mobile-responsive UI
chronological release history for each project (example)
- easy-to-read project activity journal for project maintainers
- better search and filtering
support for multiple project URLs (e.g., for a homepage and a repo)
support for Markdown READMEs for source distributions (soon: wheels too)
- user-visible Gravatars and email addresses for maintainers
- no need to "register" a project before initial upload
- far better backend infrastructure, reducing the frequency of outages
As of the middle of last year, package releases must go through the new PyPI, and as of late February, new user account registration is only available on the new site.
Things that already have gone away (sometimes for policy or spam-fighting reasons) include:
uploading to pythonhosted.com documentation hosting (we're discussing plans)
- key management: PyPI no longer has a UI for users to manage their GPG or SSH public keys
package maintainers being able to upload a new release via the web UI (instead, the recommended command-line tool is Twine)
package maintainers being able to log in and update release descriptions via the web UI (to update release metadata, they need to upload a new release; see distutils-sig discussion)
Things that will go away once legacy PyPI shuts down:
Further in the future:
deprecating the XML-RPC API and rearchitecting our APIs
And in the works:
more timely package name takeovers (PEP 541)
