static PvaClientMonitorPtr create(
    PvaClientPtr const &pvaClient,
    epics::pvAccess::Channel::shared_pointer const & channel,
    epics::pvData::PVStructurePtr const &pvRequest
);

is now changed to

static PvaClientMonitorPtr create(
    PvaClientPtr const &pvaClient,
    PvaClientChannelPtr const & pvaClientChannel,
    epics::pvData::PVStructurePtr const &pvRequest
);

A new method is also implemented

static PvaClientMonitorPtr create(
    PvaClientPtr const &pvaClient,
    std::string const & channelName,
    std::string const & providerName,
    std::string const & request,
    PvaClientChannelStateChangeRequesterPtr const & stateChangeRequester,
    PvaClientMonitorRequesterPtr const & monitorRequester
);
