That's the best explanation of FIX version differences I have seen thus = far. Somehow, it did not come across from the FIX manuals. Thanks so = much J=F6rg! =20 Naresh ________________________________ From: qui...@li... on behalf of Joerg = Thoennes Sent: Thu 3/29/2007 3:56 PM To: qui...@li...

Actually, field tags are never removed, just deprecated. Sometimes the = names change, ie from IDSource in FIX 4.2 to SecurityIDSource in FIX 4.4, but the tag value = stays the same. In addition, the tags are independent from the message type: The same = tag value has the same meaning in every message which uses it. So if you upgrade from one FIX version to the next, either a tag is = continued to be used with the same meaning (possibly a changed name) or it is deprecated (not used any = longer). Hope that makes thing clearer for you.
