Already EOL — Action Required Now
How to Stay Ahead of EOL Events 2026 is one of the most significant years for software end-of-life in recent memory. Multiple major LTS releases, widely-deployed operating systems, and enterprise-grade frameworks are all reaching the end of their support windows this year. This is your complete reference — every major EOL event in 2026, organized by month. The 2021–2022 wave of LTS releases — Ubuntu 20.04, MariaDB 10.6, Django 4.2 — are all hitting their 5-year windows in 2025–2026. Organizations that chose LTS versions for stability are now facing simultaneous migration pressure across their entire stack. The EOL Risk Score™ for any component scoring 76+ (Critical) means immediate action is warranted. Check any version at endoflife.ai. July 2026 (estimated) These reached EOL before 2026 but are still widely running in production: Use the endoflife.ai API to query upcoming EOL dates programmatically and build automated alerts into your CI/CD pipeline or ITSM system. Set 90-day and 180-day lead time reminders for every EOL date in this calendar. 90 days is the minimum time to plan and execute most migrations. 180 days is realistic for complex environments. Document everything. For compliance frameworks (SOC 2, PCI DSS, HIPAA), an EOL date in your inventory without a migration plan is a finding. An EOL date with a documented plan and compensating controls is a managed risk. Track all of these at endoflife.ai — free EOL checker, stack scanner, and EOL Risk Score™ for 455+ products.
