Some BaseClasses class' constructors have new constructor signatures. Most of the affected classes still support the old constructor signature(s), but a few require a new constructor signature. For example, some of the classes in the BaseClasses.Data namespace have new and/or altered constructor signatures.
Most customizations in existing applications that use or override a changed constructor will continue to work. However, some may need to be manually migrated to use a new constructor signature.
