Python 3.10 end of life is Oct 31: find every pinned Python and Node version
Python 3.10 reaches end of life on October 31, 2026 . Node 20 already did, on April 30, 2026 . End of life doesn't break anything. The interpreter keeps running. What stops is security releases: the next CVE in that version never gets a patch, and nothing in your build turns red to tell you. The hard part isn't upgrading. It's knowing where the version is pinned, because it's rarely in one place.…
On October 31, 2026, Python 3.10 will reach the end of its life. This update also applies to Node 20, which ended on April 30, 2026. While the interpreter continues to function, security patches cease for the discontinued versions. The challenge lies in identifying where the exact version is being pinned. This inconsistency arises as runtime versions are seldom in a single location.
Pinning can be found in various places such as Dockerfile, .python-version, runtime.txt, .nvmrc, serverless.yml, pyproject.toml, package.json, CI configurations, and others. To audit these configurations, a simple bash script is provided. This script scans for these pinned versions across various files and directories.
After conducting the audit, it's recommended to move to a version with more extended support. For Python, this means moving away from 3.10 to a newer version. Node 20 has ended, so a move to Node 22 is suggested, which has support until April 30, 2027. This move offers six more months of security updates.
It's crucial to plan for future versions as well. There are regular end-of-life dates across several programming languages including Python, Node, Ruby, Go, and Java. Therefore, setting a reminder for these updates using a tool like Versyka can be beneficial. This tool checks for pinned versions in various configurations and compares them against endoflife.date. It then alerts users 180 days before the end-of-life date via email, Slack, and the dashboard.
