NewCME STP Client Content Refresh - Now Available

As CME STP includes both FIX and FIXML API protocols, topics are split into two distinct sections and a new CME STP navigation topic is available to quickly find relevant topics. The protocol-specific session and business layer concepts are separated for clarity and message specifications are now aligned by protocol and markets.
