Engineering notes

Package Designer left SitecoreAI on 7 July in base image 1.8.24, six days after the Content Transfer and Item Transfer APIs went GA. What that breaks, who filled the gap, and the rest of an 86-item month.

Umbraco.AI 1.0.0 through 1.13.x carry a moderate information-disclosure flaw and the 1.14.0 fix is a breaking change. Plus Umbraco 18 and Elements, uSync v18, and 14 December 2026 on Umbraco 13.

Umbraco 17.4.0 exposed JSON Schema for data types and document types, which is what makes programmatic content writing verifiable. Around it: four Umbraco.AI add-ons in beta, uSync 17.3.0's version jump, and a preview-URL auth bypass.

Sixty Sitecore items cleared the February window and none came from sitecore.com. What SitecoreAI bundles, what it costs and how fast Pathways migrates all came from personal blogs — one author says outright he never ran the tool.

A thin month. Nine Umbraco items in thirty-one days, no vendor release and no advisory. What landed: uSync 17.0.2 fixing a v13 picker migration defect, the first hands-on Umbraco Compose writeup, and ISO 27001.

Thirteen items worth reading from January 2026 and not one from sitecore.com. Editing hosts in preview, Agentic Studio, custom fields via the Marketplace, and the only hard numbers of the month coming from a 10.4 stress test.

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.

Umbraco 17 shipped as a beta on 15 October with the final set for 27 November, and uSync 16.1.0 was declared the last feature release for v16. What that costs a site still on 13.
