Engineering notes

Umbraco 17 LTS landed on 27 November on .NET 10, with three years of support. uSync 17.0.0 and Clean Starter Kit v7 shipped the same day. The community had a harder month than the product did.

Four of the month's eleven Umbraco items are about MCP and AI. An agent built an element type from a single prompt, Umbraco Commerce got an MCP proof-of-concept, and the only post that said anything about who should be allowed to do that was a uSync patch note.

Two moderate advisories, the last public patch for Umbraco 10, uSync moving development to v16, and Codegarden announcements that mostly land after the v17 LTS.

Umbraco patched CMS 14 and 15 on April 8 and raised the severity from moderate to high on April 11. Plus Canadian hosting, Flexible Environments, SSO, and uSync 15.1.6.

Umbraco 8 reached end of life in February 2025, alongside Azure TLS deadlines, a Cloud WAF default and Commerce 15 throughput claims. Six citable items in the whole month, three of them from umbraco.com.

Three moderate-severity issues patched on 21 January 2025 in Umbraco 10.8.8, 13.5.3, 14.3.2 and 15.1.2 — and the catch is that you must already be on the latest minor. Six items in the whole month, half of them from Umbraco HQ.
