The initial version of the Card Services Specification was published with this release. This part of the standard PC Card software API defined the operating system extensions required for resource management of cards, sockets and drivers. Socket Services was enhanced to accommodate the requirements of the new Card Services interface. The Card and Socket Services software specifications were enhanced based on implementations done in compliance with the previous Standard to form a complete and robust software architecture and API necessary for compatible implementations. The electrical and physical sections of the standard were updated with corrections and additions, and the CIS was again improved with additional definition information.
