Hi all, There have been a few questions lately about the differences between 0-8 and 0-9. Semantically, there are few differences besides the introduction of the "work-in-progress" (WIP) classes and methods; here's a summary of the differences from the specification XML: - the advertised version number is major=0,minor=9 rather than major=8,minor=0. - some methods have been renumbered: AMQP 0-8 AMQP 0-9 Connection Redirect 50 42 Connection Close 60 50 Connection CloseOk 61 51 - some methods have been removed: Channel Alert - some classes have been removed: Test - some methods have been added: Queue Unbind, methodId 50 Queue UnbindOk, methodId 51 - some new status codes have been introduced: NO_ROUTE 312 NO_CONSUMERS 313 PRECONDITION_FAILED 406 - some methods have new arguments: Channel OpenOk has a longstr ChannelId Basic Consume has a table Filter File Consume has a table Filter Stream Consume has a table Filter The other differences are to do with the WIP sections of the spec. Framing and connection establishment (modulo the spec version number advertisement), in particular, is identical. So, anyone sticking to using 0-8 semantics has only a small step to take to move up to the 0-9 version of the protocol. Regards, Tony [/code]
