2015-09-21 Version 4.2.0 Vincent Rogier vince.rogier@ocilib.net

    * New Features:
                   
        - Implemented Oracle 12c extended support for PL/SQL types (PL/SQL boolean, records and index by tables)
        
            * These types can be now used in binding calls
            * C API: PL/SQL records can now be used using OCI_Object
            * C API: PL/SQL Index by tables can now be used using OCI_Coll
            * C API: PL/SQL boolean can be used using boolean C type
            * C API: Added OCI_BindBoolean()
            * C API: Added OCI_ElemSetBoolean(), OCI_ElemGetBoolean()
            * C API: Added OCI_ObjectSetBoolean(), OCI_ObjectGetBoolean()
            * C API: OCI_TypeInfoGet() supports now records these PL/SQL types
            * C API: Added collection type OCI_COLL_INDEXED_TABLE
            * C API: Added data type OCI_CDT_BOOLEAN
            * C++ API: PL/SQL records can now be used using ocilib::Object
            * C++ API: PL/SQL Index by tables can now be used using ocilib::Collection<T>
            * C++ API: PL/SQL boolean can be used using bool C++ type
            * C++ API: Added template specializations for supporting PL/SQL boolean using C++ bool in the following calls:
                - ocilib::Statement::Bind()
                - ocilib::Object::Get()
                - ocilib::Object::Set()
            * C++ API: Added ocilib::Collection<T> specializations for supporting bool data type
            * C++ API: Added ocilib::TypeBoolean
            * C++ API: Added ocilib::Collection::IndexedTable
            * C++ API: Added internal core class ocilib::BindTypeAdaptor<T1, T2>

         - Added Memory usage information

            * C API: Added OCI_GetAllocatedBytes
            * C API: Added OCI_MEM_ORACLE, OCI_MEM_OCILIB and OCI_MEM_ALL
            * C++ API: Added ocilib::Environment::GetAllocatedBytes()
            * C++ API: Added ocilib::Environment::OracleClientBytes, ocilib::Environment::OcilibBytes, ocilib::Environment::AllBytes

         -  Added Session Max Cursor information
        
            * C API: Added OCI_GetMaxCursors()
            * C++ API: Added ocilib::Connection::GetMaxCursors()
 
    * Enhancements:

        - C++ API:: Enhanced pre/post statement execution check for binds
        
            * Before execution, bind buffers are only updated from host variables if Bind Direction has the ocilib::BindInfo::In flag
            * After execution, host variables are only updated from bind buffers if Bind Direction has the ocilib::BindInfo::Out flag
            
    * Fixes:
        
        - C API: Fixed OCI_GetLastError() that returned NULL after OCI_Initialize() if OCI shared lib cannot be loaded
        - C API: Fixed OCI_ColumnGetSQLType() that has its break statements within the switch removed by mistake leading to return "?" in all cases
        - C API: Fixed OCI_ElemSetXXX() where XXX is a numeric type
        - C API: Fixed OCI_IterFree() when dealing with numbers
        - C API: Fixed Memory retention in local OCI objects cache when calling OCI_ObjectFree(): Objects indicator structures were not freed until calling OCI_Cleanup()
        - C API: Fixed OCI_ElemSetXXX() for numeric types when element is created using OCI_ElemCreate() instead of being retrieved with OCI_IterGetPrev() or OCI_IterGetNext()
        - C API: When OCI_SubscriptionRegister() failed, the input connection was freed leading the caller to hold a dangling pointer to the connection handle
        - C API: Fixed comparison call in OCI_TimestampCompare()
        - C API: Fixed alignment computation in OCI_GetStruct()
        - C API: Fixed alignment computation in OCI_ObjectGetUserStructSize()
        - C API: Fixed compilation under compilers that require variable to be declared at the beginning of blocks (example : VS2010)
        - C API: Fixed minor internal bugs and issues
        - C++ API: ocilib::HandleHolder<T>::Acquire() => Made sure that a smart handle is not allocated if the input C handle is NULL (even if it shall not happen as the C API must raise an error if it cannot return a valid handle)
        - C++ API: ocilib::HandleHolder<T>::SmartHandle::~SmartHandle() => the C API handle free function is now called only if the handle is not NULL
        - C++ API: Fixed compilation error when using OCI_CHARSET_WIDE
        - C++ API: Fixed ocilib::Raw binding when using OCI_CHARSET_WIDE
        - C++ API: Fixed ocilib::BindArray::BindArrayObject<Raw, unsigned char>::SetInData()
        - C++ API: Fixed binding array of Blobs
        - C++ API: Fixed binding array of Raw

    * Miscellaneous

        - Doxygen documentation: Added C and C++ data types mappings documentation page
        - Removed references to sourceforge.net
        - Minor internal code changes to fixing hypothetical issues found by code analysis (CppCheck)
        - Fixed some typos and formatting issues
