Engineering notes

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.

Sitecore 10.4.1 landed on 25 June 2025 with encrypted SQL connections, Solr 9.8.1, Identity Server on .NET 8 and a critical security fix. The community wrote it up. The same month, it wired AI agents into live instances.

Fourteen items and not one from Sitecore. Stream documented by decompiling a DLL, an MCP server built by one person, and what SUGCON 2025 left behind.

Nothing from sitecore.com in the month's harvest. What did land: a community install guide for Sitecore Stream, part four of an XP 10.4 to XM Cloud media migration, Content Hub GraphQL written up twice in one week, and an Astro SDK for JSS.

SUGCON Europe put Stream, the Marketplace SDK and an AI-first message on stage. The same month, practitioners published workarounds for Edge revalidation 429s, Sitecore Send rate limits, thin XM Cloud analytics and manual SSG filtering.

February 2025 brought field editing into XM Cloud Pages. The rest of the month was practitioners documenting what the move costs: media URLs that expire, Solr CPU, a 10.1 to 10.4 upgrade break, and a CVE that is not in the bulletin.
