azure: Retirement: Support for Python 3.10 ends on October 1, 2026 – upgrade your Azure Functions apps to Python 3.13
Microsoft will end support for Python 3.10 in Azure Functions on October 1, 2026 (in line with community support retirement). Function apps running on Python 3.10 will continue to run after that date but will no longer receive security updates or performance optimizations. Customers should plan and perform an upgrade to a supported Python runtime (Microsoft recommends Python 3.13) before the retirement date.
