New BTP Version

The new version number is 3. Users can opt into BTP v3 for UAT by setting the protocol version in the header of their login message. More information on BTP UAT is located here.

When a client logs into a pricefeed they will be sent a Market State Message for every product. Market state messages will otherwise be sent as usual on market state changes. The ack ID for these market state messages will be the most recent ack ID for the given product, it will not increment the ack ID further.

Order Entry Protocol Fill Messages Include ProductIds
