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.

Changes

The following is a list of changes compared to the previous version, version 1.0.0:

The collision properties of the invisible wall that is bypassed during First Moon Skip were altered, meaning different methods of bypassing it are possible on version 1.0.0 compared to versions 1.0.1 and later.
The Madame Broode fight can no longer be triggered before collecting Our First Power Moon, making First Moon Skip no longer useful as a sequence break.
It is now possible to clip through the ground near where the bridge lands after collecting Our First Power Moon, by ground pounding a certain spot before the bridge has fallen.
Falling off of the Warp Painting platform in the Luncheon Kingdom before reaching the kingdom normally using the Odyssey will cause the game to attempt to place Mario inside a bubble. This attempts to prevent Bruncheon, but if the bubble's safe spot is never set (which can be achieved by only standing on top of the painting, since the safe spot cannot be placed there), Mario cannot be placed in a bubble, allowing the kingdom to still be accessed early.
Warp Paintings will now only be enabled if the story in the kingdom on the other side is progressed to the point where the opposing painting opens. This eliminates some behavior where painting portals can be entered only in one direction.
Three loading zones that were erroneously active in the Snow Kingdom before completing the Bound Bowl, but that cannot be accessed early without clipping out of bounds, are now disabled.
A bug is fixed where Talkatoo in the Snow Kingdom was able to suggest moons that were only available after completing the Bound Bowl, before the Bound Bowl had actually been completed.
The metal crate containing a Moon Shard in the Second Courtyard of Bowser's Kingdom will no longer yield a coin if it is poked 200 times while inside a Pokio capture. It will still yield a coin if broken normally with a bomb. Because of this, version 1.0.1 or later is required to complete the game without collecting any coins.
Uproot hitboxes now only become active after the Uproot has fully emerged from the ground, rather than as soon as it spawns. This prevents the possibility of clipping through the floor by capturing the Uproot too early.
Capture frame teleportation is no longer possible.
Attempting to capture an Uproot the moment it touches lava will no longer result in a softlock, and will instead simply result in Mario capturing the Uproot followed by the Uproot dying and forcing Mario out.
Coin duplication is now possible.
Capturing a Hammer Bro just as a turnip is about to collide with it no longer results in a softlock (due to the Hammer Bro dying as it is captured), but now results in the Hammer Bro clipping through the ground.
