BOSS released MS-3 System Program Ver.1.20 in November 2024, according to the update history on the company's MS-3 support page. The release lists a single change: the Auto Off time.

The MS-3 is a multi-effects unit, and the update falls under the heading "Change the specification" in the history. The entry reads:

The page directs readers to the MS-3 owner's manuals for information on the Auto Off function. It gives no other changes for Ver.1.20 and no price or availability details, since the update is a free download.

The same page lists later and earlier releases. Ver.1.21, dated June 2025, fixes an issue where MIDI control change was not transmitted with the correct value. Ver.1.10, dated January 2022, states that "The version number has been updated due to management-related circumstances" and that product specifications are unaffected. Earlier entries from Ver.1.03 in August 2017 through Ver.1.09 in October 2021 cover added Editor/Librarian support and various bug fixes.

The page's update instructions are written for Ver.1.21 and describe checking the installed version by holding [ENTER] while powering on, then copying the update files to the MS-3 over USB. It warns that powering off during an update can leave the unit unable to start in normal operating mode, which would require servicing.
