Engineering notes

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.

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.

March's advisory fixed two moderate CMS issues plus a high-severity ImageSharp CVE, but only on the latest minor of each supported major. Also: uSync 13.2.7 and 15.1.5, a V8-to-V13 upgrade written up honestly, and a backoffice accessibility fix.

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.

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.

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.

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.

A backfilled month, reached through feed archives. Twelve Sitecore posts worth your time, all written by practitioners: Edge webhook timeouts, two 10.4 upgrade logs, Astro on XM Cloud, and two posts called Sitecore Search that mean different things.
