Seperation of Session and application layers is the biggest difference. There are two thing here:- Transport Independence - This permits use of non-TCP Sessions Application version independence - This permits multiple versions of FIX application messages to be carried over a single FIX session Jim Northey is submitting a proposal to permit firms without the need for application version independence or transport independence to simply use 8=FIX.5.0, 8=FIX.5.0SP1, 8=FIX.5.0SP2, etc. refer http://fixprotocol.org/discuss/read/792b31ea Also check the release notes / appendix of the specs to see differences between versions. In FIX repository, there is a "TOOLS AND SAMPLES" described as "Compare FIX Messages between versions (Sample Application.zip, 14KB) A simple XSLT that compares the Tags that make up each message in FIX to the Tags that make up the same message in another version. The results are displayed as a basic HTML document". This XSLT tool is available at http://fixprotocol.org/documents/874/Sample%20Application.zip (You need to be logged in to access the above zip. ) > Hi, Can I know what is the difference between FIX4.4 and FIX5.0? > Is it just unlock the application layer from session layer?
