System 3, released concurrent with the Mac Plus, brought several new features including HFS (Hierarchical File System) and SCSI (Small Computer System Interface). It is one of the most significant evolutions in the Mac operating system, second (or perhaps third) to the advances made with Mac OS 7. System 3.1 was a rare misstep for Apple, and was quickly replaced with System 3.2 which fixed many of the previous releases' bugs.
