- Dev : The code has had a lot of modernisation changes, and some refactoring which imply incompatibility with previous versions requiring changes. List of changes necessary if you would like to migrate one of your plugins, compatible with OpenViBE 2:
  - OpenViBE types were removed and replaced with standard types:
    - `OpenViBE::uintXX` -> `uintXX_t`
    - `OpenViBE::intXX` -> `intXX_t`
    - `OpenViBE::float64` -> `double`
    - `OpenViBE::boolean` -> `bool`
  - Some functions from `System::Memory` were removed and replaced with standard equivalent:
    - `System::Memory::copy()` -> `std::memcpy()`
    - `System::Memory::move()` -> `std::memmove()`
    - `System::Memory::set()` -> `std::memset()`
    - `System::Memory::compare()` -> `std::memcmp()`
  - Namespaces starting with OpenViBE having been split:
    - `OpenViBEPlugins` -> `OpenViBE::Plugins`
    - `OpenViBEToolkit` -> `OpenViBE::Toolkit`
    - `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`
    - variables with `SamplingRate` renamed with `Sampling`
    - e.g. `OVP_GD_Algorithm_SignalEncoder_InputParameterId_SamplingRate` -> `OVP_GD_Algorithm_SignalEncoder_InputParameterId_Sampling`
    - `OVP_ClassId_Plugin_VisualizationContext` -> `OVP_ClassId_Plugin_VisualizationCtx`
  - The include file `<openvibe/ovITimeArithmetics.h>` was removed and functionalities replaced:
    - New header: `#include <openvibe/ovITimeArithmetics.h>` -> `#include <openvibe/CTime.hpp>`
    - `TimeArithmetics::timeToSeconds(timeVar)` -> `CTime(timeVar).toSeconds()`
    - `TimeArrithmetics::SecondsToTime(timeVar)` -> `CTime(timeVar).time()`
    - `TimeArithmetics::TimeToSampleCount(freqVar, timeVar)` -> `CTime(time).toSampleCount(freqVar)`
  - 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)`
