## TL;DR

Installing mixpanel 4.10.1 suddenly started failing with requirements mismatches, demanding requests>=2.32.5 even for users pinned to older requests versions. Another maintainer confirmed the misconfiguration in PyPI metadata had been fixed for v4.10.1.

## Steps

1. Installing mixpanel 4.10.1 suddenly started failing with requirements mismatches, demanding `requests>=2.32.5` even for users pinned to older requests versions. Multiple users reported broken release workflows on the same day. A maintainer said the library did not actually require requests that new and that they would fix it that day. Another maintainer confirmed the misconfiguration in PyPI metadata had been fixed for v4.10.1. Users could then install 4.10.1 cleanly, with 4.10.0 as the fallback in the meantime.

2. The 4.10.1 release shipped with wrong PyPI metadata that demanded `requests>=2.32.5`, which the library never actually needed. Fix: reinstall or upgrade to mixpanel 4.10.1 now, the PyPI metadata was corrected by the maintainers and installs resolve normally again. If your lockfile still resolves the bad metadata, clear your pip cache and retry. As a fallback, mixpanel 4.10.0 installed fine throughout the incident.

## Versions

Versions mentioned in the source: mixpanel 4.10.1, requests 2.32.5, v4.10.1, 4.10.0. If you are on something much newer or older, the details may have shifted.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
