Why Use Ruby Health Badges?
Ruby’s branch-based support model means old versions quietly stop getting CVE patches. A health badge in your gem’s README shows users exactly where their Ruby version stands, with no changelog archaeology required.
ReleaseRun badges go beyond Shields.io. While Shields.io displays a version number, our badges show security posture: CVE counts, EOL countdowns, and a composite health grade that factors in freshness (35%), security (35%), and support status (30%).
Ruby Release History & EOL Timeline
Ruby follows a Christmas Day release tradition, with a new minor version typically landing every December 25th. Each version receives approximately one year of active bug fixes followed by one additional year of security-only patches, giving roughly two years of total coverage per release.
- Ruby 3.4 – released December 2024. Current stable release. Active bug-fix support through late 2025, security fixes expected until early 2027.
- Ruby 3.3 – released December 2023. Transitioned to security-only maintenance in late 2024. Expected EOL around March 2026.
- Ruby 3.2 – released December 2022. Security-only phase since late 2023. Approaching end-of-life in March 2026. Plan your migration now if you are still running this version.
- Ruby 3.1 – released December 2021. Reached end-of-life in March 2025. No further patches of any kind. The ReleaseRun EOL badge turns red automatically for this version.
- Ruby 3.0 – released December 2020. End-of-life since March 2024. Running this in production means zero security coverage.
- Ruby 2.7 – the last 2.x release. End-of-life since March 2023. Still found in legacy Rails applications that have not yet migrated to Ruby 3.
Because Ruby’s support windows are shorter than languages like Python or Java, staying current matters more. Health badges give your users a clear, visual signal when a version is approaching the danger zone.
Badge Customization Examples
ReleaseRun offers four badge types for Ruby. Each serves a different monitoring purpose:
- Health badge – composite A-F grade reflecting overall risk. Embed:
 - EOL badge – end-of-life countdown or status. Embed:
 - Version badge – latest stable version number. Embed:
 - CVE badge – known vulnerability 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
- Gem maintainers: Show which Ruby versions your gem supports and flag when any of them drop out of security maintenance. Users running Ruby 3.1 on a production Rails app need to know it is time to move.
- Rails teams: Embed badges in internal wikis or Confluence pages to track Ruby versions across services. Upgrade planning starts with knowing what you are running.
- CI/CD pipelines: Add Ruby health badges to your build status pages. When your tested Ruby version goes EOL, the badge provides a visual alert before your security team files a ticket.
- Documentation sites: Add version health next to installation instructions so developers do not unknowingly target an EOL runtime.
Related ReleaseRun Tools
Ruby badges are part of a broader toolkit for managing your Ruby dependency lifecycle:
- Dependency EOL Scanner – scan your
GemfileorGemfile.lockand flag any dependency approaching end-of-life. - Tech Stack Health Scorecard – get a holistic health grade across your entire stack, not just Ruby.
- Upgrade Path Planner – plan your migration from Ruby 3.1 to 3.4 with step-by-step guidance and breaking change alerts.
- EOL Timeline Visualizer – see all your Ruby version EOL dates on an interactive timeline alongside Rails and other dependencies.
- Badge Generator – create custom health badges for any product in the ReleaseRun database.
What Makes These Different
Every badge pulls live data from the endoflife.date API and the NIST National Vulnerability Database. Data refreshes every 6 hours. Badges are edge-cached for 5 minutes, fast enough for CI pipelines and documentation builds.
Ruby Versions
Security Overview
CVE vulnerability data is sourced from the NIST National Vulnerability Database (NVD) and refreshed every 6 hours.
Check specific version CVEs using the badge builder above or visit our Ruby hub page for detailed security analysis.
Upgrade Guidance
Running an older version of Ruby? 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 Ruby documentation for detailed upgrade instructions.
