Umbraco CMS

Umbraco 13 will reach End of Life on December 14, 2026. The underlying .NET 8 platform will reach the end of Microsoft support even earlier, on November 10, 2026.

Your website will not suddenly stop working when these dates pass. However, regular security updates and support will cease, making the solution increasingly difficult and risky to maintain.

Organizations using Umbraco 13 should therefore evaluate their upgrade options well in advance of the end dates, rather than waiting until a security issue or change in the operating environment forces an emergency migration.
