Engineering notes

The first ten days of August 2026 in Sitecore: an XP 10.5 release described as Solr 10 only, package installation off by default, Pathway's migration boundaries, and a CVE fix in Next.js 16.3.0.

From 1 June, Extended Support stops including security patches and production incident support. Content SDK 2.0 requires Next.js 16 and renames middleware.ts. And the manual for Sitecore's AI surface is being written by volunteers.

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.

Symposium folded XM Cloud, CDP, Personalize, Search and Content Hub into SitecoreAI. 106 items harvested, 14 cited, zero published by the vendor. What is confirmed, what is second-hand, and what to check before signing.

A YAML error that writes a 0 KB resource package and still returns success, the JSS to Content SDK decision, and an agentic product surface explained by practitioners instead of by Sitecore.

Content SDK 1.1 landed and the Experience Editor did not come with it. Every account of that migration in our September 2025 harvest came from a personal blog, not from a vendor page.

Sitecore 10.4.1 requires encrypted SQL for Identity Server and greets upgraders with a login failure. Plus the Marketplace SDK's first wall, Stream on XP, and a month of XM Cloud migration guides.

The month the community installed 10.4.1 and documented what broke: Identity Server's encrypted SQL requirement, Solr 9.8.1's max-fields limit, plus MCP Server 1.0.0, Stream REST APIs and the Content SDK beta.
