In November 2026, Chrome is going to remove support for XSLT in the browser. XSLT support in the browser has been around since 1999 and many organizations have applications that still depend on this technology - if you have a small IT department, make sure that you give them a heads up because the impact of this change can affect many different applications beyond Tridion Sites.

For Tridion Sites, the ClassicUI does have panels that use XSLT but the new Experience Space is unaffected. Since there are some essential Admin panels that are still in the ClassicUI, everyone will have to apply the fixes.

Please read the KB Article for more details about how we're addressing the issue and what to do in August when we release a fix pack for the various releases.  We will provide another update one the fixes are available.
