System 3.2 was released in June 1986 along with Finder 5.3 under the title Macintosh System Software 1.1. This release was mainly a bug fix.
The Calculator DA had its keys redesigned. The old Calculator's buttons didn't match the layout of the numeric keypad (the division, multiplication and equation buttons were arranged in the wrong order).
The LaserWriter driver was updated to 3.1.
