Projects owned by a PyPI organization now get higher limits by default: Personal projects Organization projects Largest file you can upload 100 MB 200 MB Total size of a project 10 GB 20 GB There’s nothing to turn on. Every project owned by either a company or community organization getsContinue Reading
PyPI now rejects new uploads whose version is longer than 128 characters. This affects almost no one: across the roughly 9.9 million releases on PyPI, only 2 have a version that long. Releases that are already on PyPI stay exactly as they are, and installing them works the same asContinue Reading
PyPI improves on checks for the reputation of an email address when used to register an account or add to an existing account, and rejects addresses identified as disposable. With the new check in place, outlook.com and hotmail.com addresses can once again be used on PyPI. Background In June 2024Continue Reading
Executive summary For about two weeks in August 2026, some PyPI users hit intermittent 502 and 503 errors downloading files from files.pythonhosted.org, triggering failures during installation from PyPI. Thanks to our users filing reports in the support tracker; one report in particular narrowed the problem to a single cache node.Continue Reading
On 2026-08-24 I shipped a change to the configuration that emits PyPI’s download logs so that only requests for actual distribution artifacts are counted. A request has to end in .whl, .tar.gz, or .zip to produce a download record. The counts are more accurate now, and existing systems based onContinue Reading
Working on infrastructure at the Python Software Foundation (PSF) as the Director of Engineering is a broad job with many hats. Python turns up everywhere. It’s in healthcare systems and government agencies, in research labs and classrooms, in one-person side projects and in infrastructure at companies with six-figure headcounts. SomebodyContinue Reading
PyPI has adopted PEP 833, which “freezes” the HTML representation of the index API, which is also sometimes called the “simple API” or the “simple repository API.” New packages and releases will continue to appear in the HTML representation, meaning this has no breaking implications for downstream index consumers. However,Continue Reading
The Python Package Index (PyPI) now rejects new files being uploaded to releases that are older than 14 days. This restriction was put in place to prevent old and long-stable releases from being poisoned in case publishing tokens or workflows of PyPI projects were compromised. As far as we areContinue Reading
Over the next few months, we will be rolling out changes to the PyPI user interface, improving how we surface security signals and updating the pages where users view package details. Updates will be staged to TestPyPI and deployed to production in phases. This approach allows our team to thoroughlyContinue Reading
Highlighting the next stage in our sidebar reorganization campaign! We are still primarily focusing on Organization Dashboards (which have the highest financial complexity) and gradually introducing changes to individual and collective dashboards. As a reminder, the intention behind this redesign is to make the platform more coherent, intuitive, and welcoming,Continue Reading
