2026 Software EOL Calendar: Critical Migration Dates for Engineers

The Complete EOL Calendar for 2026 — Every Major Software End-of-Life Date
The 2021–2022 wave of LTS releases is hitting their support windows in 2026. This includes widely deployed systems like Ubuntu 20.04 and MariaDB 10.6.
Why This Matters
Organizations prioritizing stability via LTS versions are now facing simultaneous migration pressure across their entire stack. In technical reality, an EOL date without a documented migration plan constitutes a compliance finding for frameworks such as SOC 2, PCI DSS, and HIPAA.
Key Insights
- Critical risk thresholds: Components scoring 76+ on the EOL Risk Score™ require immediate action (endoflife.ai, 2026).
- LTS transition cycles: Debian 12 transitions from regular support to LTS on June 10, 2026, narrowing package coverage.
- Programmatic tracking: The endoflife.ai API allows engineers to integrate EOL dates into CI/CD pipelines or ITSM systems.
Practical Applications
- …Use case: Integration of endoflife.ai API into automated alerts to maintain security compliance… Pitfall: Waiting until the EOL date to begin migration; minimum recommended lead time is 90 to 180 days.
- …Use case: Documenting compensating controls for legacy versions in SOC 2 audits… Pitfall: Treating an EOL version as ‘stable’ without a migration plan, resulting in audit findings.
