What you may have missed in the Acumatica Community! July, 2026

Hi Chris, would you happen to have any information on the 2026 R1 Chromium/XLST patch? I’m finding bits and pieces of information, and I think it may have been deployed but I’m not confident it has. 

Thank you!

Summary — 2026 R1 Chromium / XSLT

• A patch addressing Chromium XSLT deprecation for Classic UI in 2026 R1 was released as part of the 2026 R1 patch cycle (GA build 26.100.0175.3, July 3, 2026). This patch includes a fix (AC-370702) that enhances Classic UI support so screens render correctly when client-side XSLT is removed from Chromium-based browsers (Acumatica ERP 2026 R1 GA Build 26.100.0175.3 - July 3, 2026).
• The Chromium XSLT deprecation and its impact on Classic UI (screens failing to load in Chromium-based browsers) was communicated as an issue and action item; Acumatica documented the root cause and recommended migrating to Modern UI as the long-term solution (Troubleshooting: Acumatica ERP screens on Classic UI won't load in Chromium-based browsers because of XSLT deprecation).
• Deployment behavior: the 26R1 patch that includes the Chromium/XSLT compatibility fix was scheduled and published (typical maintenance for SaaS customers is automatic; private cloud/PCS customers apply the patch manually) (Chromium XSLT Deprecation Affecting Classic UI — Action Required; Acumatica ERP 2026 R1 GA Build 26.100.0175.3 - July 3, 2026).

What the patch does (key point)

• Implements server-side support/workarounds so Classic UI screens render correctly in Chromium-based browsers after client-side XSLT processing is removed (fix AC-370702) (Acumatica ERP 2026 R1 GA Build 26.100.0175.3 - July 3, 2026).

Practical notes

• SaaS customers on 2026 R1 receive the patch automatically during scheduled maintenance, while private cloud / PCS customers must apply the patch manually using Acumatica’s PatchTool and the documented patch installation steps (Acumatica ERP 2026 R1 GA Build 26.100.0175.3 - July 3, 2026).
• Acumatica’s longer guidance recommends migrating to Modern UI (which does not rely on client-side XSLT) as the durable solution to avoid future browser-compatibility risks (Troubleshooting: Chromium XSLT deprecation).

Note: The community announcement and patch notes contain further details about timing, affected versions, and workarounds.

Hi Chris, thank you for this, but I temporarily disabled Chromium/XSLT and the couple GIs I checked stopped working. We’re on 26R1 - build 26.100.0175. Seems like the patch has not been implemented.
