CSDK v2.81 TC-1 vs TC-2 What's the difference?

Hi Everyone, I just checked the Informix downloads page (http://www14.software.ibm.com/webapp/download/search.jsp?go=y&S_TACT=&S_CMP =&s=&q=informix ) and found that the Informix Client SDK v2.81 TC-2 was released. We're using the TC-1 release and I'm wondering what the difference is? I've downloaded TC-2 and tried to compare the release docs, but I couldn't find any real differences. We're only using the ODBC driver at this time in our applications and I'd rather not go through the effort to distribute this new version unless I have to. Any insider info?
