Version 1.0.1

Version 1.0.1 is a version of the game that was released as a day-one patch, meaning it was available from the moment Super Mario Odyssey released digitally. The patch included a number of tweaks implemented as preventative measures to prevent certain types of exploits, such as removing certain sequence-breaking behavior. Because it was a day-one patch and glitch hunters had not had the chance to experiment with the game yet, the version 1.0.1 patch primarily contains fixes aimed at preventing unintended behavior prematurely, rather than patches to specific glitches or exploits.

Version 1.0.1 and version 1.1.0 are often collectively referred to as "version 1.1", since the only difference between them is Korean language support, although this terminology can often be slightly misleading.
