Github user gemmellr commented on the pull request: https://github.com/apache/qpid-proton/pull/53#issuecomment-172938973 Hi Sreeram, As you might have already seen from the JIRA update or commit just now, I have made a further update here to go back to using an int to carry the 32bit value for the message format. My change to use a long had caused some compatibility issues that I don't think it is important enough a change to warrant, so I've put it back to the int. If you were just using an int (as your original PR would have needed), or perhaps explicitly casting a long to int, then you shouldnt have to change anything, but if you were now passing in a long directly after the earlier changes you will need to make some updates too, in which case apologies for any hassle caused.
