EOL vs EOS: understand the support timeline
Understand end of support, end of life, maintenance and paid extended support, and learn how to compare release timelines before planning upgrades.
End of support (EOS) marks the end of active or mainstream support when announced. End of life (EOL) usually marks the end of standard or security support. Definitions can differ by product.
Maintenance only means active support has ended, but the release is still within its remaining support window. Paid extended support is displayed separately and does not change standard EOL status.
Ending soon means the next 180 days. Dates are inclusive and evaluated in UTC. Not announced means no date is available, not a promise of indefinite support.
The catalog is updated automatically. Check the update indicator for freshness and open a product's full timeline to compare editions and releases. A product's data update time records retrieval, not necessarily when its provider published a change.
Before planning an upgrade, choose the exact version or hardware edition, compare active and security support dates, and check whether any extended support requires a separate agreement. Unknown dates should not be treated as unlimited support.
