Release Notes are here.

Processor and RAM requirements are minimum recommendations. In general, “more” and “faster” are desirable when contemplating these system resources.

More disk space is needed for image storage, and temporary disk space is needed during conversion, compression, and decompression. The amount of disk space required depends on your images. Faster hard drives, large disk caches, and SSD or hybrid drives will improve application performance.
