Why Use Python Health Badges?
Your users deserve to know if their Python version has unpatched CVEs. A health badge in your README or docs gives instant visibility into version risk — no changelog reading required.
ReleaseRun badges go beyond what Shields.io offers. While Shields.io shows version numbers, our badges show security posture: CVE counts, EOL countdowns, and an overall health grade that factors in freshness (35%), security (35%), and support status (30%).
Python Release History & EOL Timeline
Python follows an annual release cadence — a new minor version every October since Python 3.9. Each version receives two years of active support followed by three years of security-only fixes, totalling five years of coverage.
- Python 3.14 — released October 2025. Current stable release. Active support until October 2027.
- Python 3.13 — released October 2024. Active support until October 2026, security fixes until October 2029.
- Python 3.12 — released October 2023. Transitions to security-only in October 2025.
- Python 3.11 — security-only since October 2025. EOL October 2027.
- Python 3.10 — security-only since October 2024. EOL October 2026. If you are still on 3.10, plan your upgrade now.
- Python 3.9 — reached end-of-life in October 2025. No more patches, including security fixes. The ReleaseRun EOL badge turns red automatically.
The Python release schedule means multiple versions are always active simultaneously. Health badges cut through the confusion: a green badge means safe, amber means approaching EOL, red means unsupported.
Badge Customization Examples
ReleaseRun offers four badge types for Python. Each serves a different monitoring purpose:
- Health badge — composite A–F grade. Embed:
 - Freshness badge — shows how current a specific version is. Embed:
 - EOL badge — end-of-life status per release cycle. Embed:
 - CVE badge — known vulnerabilities count. Embed:
Add ?style=flat-square or ?style=for-the-badge to any URL for alternative rendering. The embed builder above lets you preview all styles before copying.
Common Use Cases
- Library maintainers: Show which Python versions your library supports and their health status. When Python 3.10 reaches EOL in October 2026, your badge automatically warns users to upgrade.
- DevOps teams: Embed badges in internal wikis or dashboards to track which Python versions are running across services.
- Documentation sites: Add version health badges next to installation instructions so users know they are installing a supported, secure version.
Related ReleaseRun Tools
Python badges are part of a broader toolkit for managing your Python dependency lifecycle:
- Dependency EOL Scanner — scan your
requirements.txtorpyproject.tomland flag any dependency approaching end-of-life. - Tech Stack Health Scorecard — get a holistic health grade across your entire stack, not just Python.
- EOL Timeline Visualizer — see all your Python version EOL dates on an interactive timeline.
- Upgrade Path Planner — plan your migration from Python 3.10 to 3.13 with step-by-step guidance.
- CVE Dashboard — monitor known vulnerabilities across all your tracked products including Python.
- PyPI Package Health Checker — check any Python package for EOL status, known CVEs, and active maintenance before pip install.
What Makes These Different
Every badge pulls live data from the endoflife.date API and NIST National Vulnerability Database. Data refreshes every 6 hours. Badges are edge-cached for 5 minutes — fast enough for any CI/CD pipeline or documentation site.

Upgrade Guidance
Running an older version of Python? Here's what to consider when planning your upgrade:
- Check breaking changes in release notes
- Review EOL dates for your current version
- Test in staging before production rollout
- Consider LTS versions for stability
See the official Python documentation for detailed upgrade instructions.
