New or changed New platform support — This release is a candidate for same-day support of the upcoming Microsoft Windows 20H2 release for workstations and servers. Memory footprint reduction (32-bit systems) — MACC's memory use in the kernel mode and in the user-mode can be attributed to the inventory data structure. The inventory data structure uses 70% to 90% of MACC's memory depending on the configuration of the system. Improvements are made to the inventory data structure to reduce the memory consumption footprint.
