* Feature: Allow additional version check on startup - added versionCheckCallback - added apiVersion to DeviceObject - added new versionCheck to memory,cpp * updated source code formatting * changes for PR - (old) version is again part of version check - naming conventions * forgotten parameter in callback * correct wrong buffer initialization * version <-> apiVersion swapped Co-authored-by: Waldemar Porscha <waldemar.porscha@sap.com>
