Citrix App Layering 2503 released yesterday: https://www.citrix.com/downloads/citrix-app-layering/product-software/citrix-app-layering-2503.html https://docs.citrix.com/en-us/citrix-app-layering/4/whats-new.html

We haven't even started our migration to 2409, so I'm glad to see that most of these fixes are for Teams...

no direct upgrade path from 2403?

No, because 2409 is the new Oracle Linux 8 base OS for the ELM. Migration is required.
