With respect to previous versions of the control some of the control's properties and methods have been deprecated. Deprecated elements should not be used in new development projects. They have been maintained internally for backward compatibility only and they will not be documented here nor supported in the future. Furthermore, deprecated elements will not be displayed by Intellisense and, in Visual C++, will not be inserted inside the wrapper class.
The following is the full list of obsolete properties and methods with the current alternative you should use from now on:
(*) Deprecated starting from version 2
(**) Deprecated starting from version 2.3
(***) Deprecated starting from version 3
