Added XFRM versioning support for Purchasable Resources. When Enable versioning is selected for a resource category, the Purchasable Resource form now displays an initial version-number field. Existing purchasable resources can also use XFRM’s standard resource-update and version workflow. Regular resources and ordinary fileless resources remain unchanged.
