    • OpenViBE::intXX -> intXX_t
    • OpenViBE::float64 -> double
    • OpenViBE::boolean -> bool

    • OpenViBEVisualizationToolkit -> OpenViBE::VisualizationToolkit
    • Some ClassId variables were renamed:
    • variables containing StreamedMatrixStreamDecoder renamed with StreamedMatrixDecoder
    • e.g. OVP_GD_ClassId_Algorithm_StreamedMatrixStreamDecoder -> OVP_GD_ClassId_Algorithm_StreamedMatrixDecoder
    • variables with StreamedMatrixStreamEncoder renamed with StreamedMatrixEncoder
    • e.g. OVP_GD_ClassId_Algorithm_StreamedMatrixStreamEncoder -> OVP_GD_ClassId_Algorithm_StreamedMatrixEncoder

    • In the package ovp_main.cpp, after the call to OVP_Declare_Begin(): rPluginModuleContext -> context
    • Signature of method processInput() overriden from class TBoxAlgorithm has changed (parameter type uint32_t -> const size_t):
    • OpenViBE::boolean processInput(OpenViBE::uint32) -> bool processInput(const size_t index)
    • Signature of method hasFunctionality() overridden from class IPluginObjectDesc (in sdk/openvibe/include/openvibe/plugins/ovIPluginObjectDesc.h) has changed:
    • OpenViBE::boolean hasFunctionality(OpenViBE::CIdentifier functionalityIdentifier) const -> bool hasFunctionality(const EPluginFunctionality functionality) const
    • #define OVD_Functionality_Visualization replaced by EPluginFunctionality::Visualization
    • Method renamed to match coding rules:
    • TCPTagging::createStimulusSender() -> TCPTagging::CreateStimulusSender()
    • Signature of box processClock() may have changed. Both were used, but now only the latter:
    • bool processClock(Kernel::IMessageClock& msg) -> bool processClock(Kernel::CMessage& msg)
