      - Added OCI_ConnPoolGetOpenedCount()
      - Added OCI_ConnPoolGetMin()
      - Added OCI_ConnPoolGetMax()
      - Added OCI_ConnPoolGetIncrement()

    * Added Support for OCI Mutexes
     
      - See new section in the documentation (page <module>, section <Threads and mutexes>)
      - Added type OCI_Mutex
      - Added OCI_MutexCreate()
      - Added OCI_MutexFree()
      - Added OCI_MutexAcquire()
      - Added OCI_MutexRelease()

    * Added Support for OCI Threads
     
      - See new section in the documentation (page <module>, section <Threads and mutexes>)
      - Added type OCI_Thread
      - Added OCI_ThreadCreate()
      - Added OCI_ThreadFree()
      - Added OCI_ThreadRun()
      - Added OCI_ThreadJoin()

    * Extended support for public retrieval of internal OCI handles :

      - Added OCI_HandleGetMutex()
      - Added OCI_HandleGetThread()
      - Added OCI_HandleGetThreadID()

    * Extended Lobs support :

      - Added OCI_LobAssign()
      - Added OCI_FileAssign()

    * Extended "Formatted" functions support :

      - Added support for OCI_Timestamp (<%p>) and OCI_Interval(<%v>)

    * Public interface (IMPORTANT CHANGES)

      - OCI_Initialize() :

        * New flag : OCI_ENV_THREADED
        * Up to v2.2.0, OCILIB was internally initializing OCI in threaded mode (even for non threaded applications)
        * With  v2.3.0, applications HAVE TO SET EXPLICITLY the flag OCI_ENV_THREADED for multithreaded applications

      - Normalization of few Function Names :

        * OCI_CreateConnection() -> OCI_ConnectionCreate()
        * OCI_FreeConnection() -> OCI_ConnectionFree()
        * OCI_CreateStatement() -> OCI_StatementCreate()
        * OCI_FreeStatement() -> OCI_StatementFree()

      - Added Macro for existing code compatibility

    * Bug fixes :

      - OCILIB_MINOR_VERSION was not updated
      - A segmentation fault could happen when fetching Long column
      - If an OCI_Statement object or its internal handle couldn't be allocated, the entry was not removed from the connection statements list
      - Binding and fetching Unicode strings on national character columns: non ansi characters (code points) were badly converted (Now, it uses national charset form for conversion)
      - OCI_LobErase() : Offset value was wrongly used (shifted by 1) and could cause an error if set to zero
      - OCI_Immediate() and OCI_ImmediateFmt() :

        * Passing OCILIB objects for output result led to crash because of assignment of out-of-scope object pointers
        * Now, pass the OCILIB object handle, NOT the handle address
        * Now, OCI_Long, OCI_Statement are not handled

    * Miscelleanous

      - Added OCI_ReleaseResultsets() : optional call to release resultsets
      - OCI_SetPrefetchSize() and OCI_SetPrefetchMemory() : internal value is now set only is OCI call succeed
      - Internal connection rewrite for handling Connection pool
      - Renamed few function parameters + documentation updates
      - Unicode strings are now converted into database using national charset form
      - OCI environment handle : 

        * Up to v2.2.0, every connection object holded an environment handle
        * Now, there is an unique environment handle associated to the internal OCI_Library object
