What end of life actually means
-
No more security patches
New vulnerabilities in Umbraco 13 won't be fixed after 14 December 2026.
-
Compliance risk
Unsupported software can cause problems for Cyber Essentials, audits and procurement checks.
-
Your site keeps working
Nothing switches off on the day. But the risk grows the longer you leave it.
Your options

Recommended
Upgrade to Umbraco 17 LTS
Move to the current long-term support release. Security updates for years to come, plus everything new in Umbraco since 13.
-
Buying time
Extended support (XLTS)
Umbraco offers paid extended security support for version 13. Useful if you need longer to plan, but it only delays the upgrade.
