Is there official guide for Python 3.x release lifecycle?

I just noticed Python 3.2 was removed from the drop down selector in Python Docs. I have a framework using Python 3.3, so I'd like to know when it'll share the same fate, and move to a newer version before this happens.

Is there an official guide on how long Python 3.x gets support, backports, etc.? I couldn't find any information about Python release lifecycle on Python's home page or via search engines.

Updated schedule (as of August 2022):

• Python 3.4: reached End Of Life
• Python 3.5: reached End Of Life
• Python 3.6: reached End Of Life
• Python 3.7: security fixes only, no bug fixes will be provided; End Of Life: 2023-06-27
• Python 3.8: security fixes only, no bug fixes will be provided; End Of Life: 2024-10
• Python 3.9: security fixes only, no bug fixes will be provided; End Of Life: 2025-10
• Python 3.10: security fixes AND bug fixes will be provided; End Of Life: 2026-10
• Python 3.11: security fixes AND bug fixes will be provided; End Of Life: 2027-10

Also notice that Python release cycle has changed to 12 months since Python 3.9. See PEP-602 for more details. It used to be 18 months for Python 3.8 and prior releases. This means we should see Python 3.9 before end of year 2020!
