MS-DOS 3.31 wasn't a mainstream Microsoft release — it was a Compaq OEM version from late 1987. COMPAQ DOS 3.31... pioneered support for 32-bit logical sector numbers and thus partitions larger than 32MB, and that same mechanism appeared a few months later in DOS 4.0 and OS/2 1.1. So 3.31 beat Microsoft's own DOS to large-partition support.
MS-DOS 3.31 introduced support for 1.44M diskettes and support for hard drives up to 512MB.
It also does not use as much conventional memory as DOS 4.x or later, making it a good choice for 8088/8086 based computers.
