Python end of life: end of support by version
Python Software Foundation · Development & DevOps
For Python by Python Software Foundation, patchletter knows 12 support cycles. 7 of them have already ended and receive no more security updates. The next support window closes on 31/10/2027, that is in 385 days. The current version of Python is 3.15.0. The cycles come from the open endoflife.date project, last reconciled on 30/09/2026.
When does support end for which Python version?
A cycle is a maintained version line. Where a date is given, support ends on that day — after it the vendor ships no more security updates for that line.

Where does the EOL data for Python come from?
From the open endoflife.date project, which collects vendors' official support commitments. patchletter reconciles the cycles daily; the Python data is as of 30/09/2026. In case of doubt the vendor's own lifecycle page applies — patchletter deliberately stores no vendor full texts.
