 FEATURES:
 
 ENHANCEMENTS:
+* Key Vaults should use RBAC instead of access policies for access control ([#4000](https://github.com/microsoft/AzureTRE/issues/4000))
 * Split log entries with [Log chunk X of Y] for better readability. ([[#3992](https://github.com/microsoft/AzureTRE/issues/3992)
 * Expose APP_SERVICE_SKU build variable to allow enablement of App Gateway WAF ([#4111](https://github.com/microsoft/AzureTRE/pull/4111))
 * Update Terraform to use Azure AD authentication rather than storage account keys ([#4103](https://github.com/microsoft/AzureTRE/issues/4103))
