	Change	Effect
1	Pure virtual method DBClientBase::isMember ( DBConnector const* conn ) const has been added to this class.	1) Applications will not provide the implementation for this pure virtual method and therefore cause a crash in the library trying to call this method. 2) The layout of v-table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.
2	Virtual method DBClientBase::getServerAddress ( ) const has been removed from this class.	The layout of v-table has been changed. Call of this virtual method or any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.
