+* Workspace bundle uses infrastructure encryption on shared storage which will recreate storage share. Major verison increase will prevent upgrade, do not force the upgrade unless you are fully aware of the consequences.
 ENHANCEMENTS:
 * Core key vault firewall should not be set to "Allow public access from all networks" ([#4250](https://github.com/microsoft/AzureTRE/issues/4250))
 * Allow workspace App Service Plan SKU to be updated ([#4331](https://github.com/microsoft/AzureTRE/issues/4331))
