A full changelog can be found in the Readme File: https://pastebin.com/sZ7JAV9W.

1.20.1 is just a small bugfix update:

- Fixed an issue where Gjalrunn would be hostile when you run into him on the road later on despite helping him out.
- Fixed incorrect ownership on the beds in the Laenius household.
- Removed the smelting recipes for Wyrmstone and Brimstone.
- Lurius' response to 'The dragon is dead' is no longer set to Say Once, which could potentially lock the player out of the ending.
- Fixed some minor object placement issues.
- Fixed an issue where starting The Naked Nord before completing the miscellaneous objective to kill the Krakevisa Midden boss would prevent that objective from being completable.
- Fixed condition issue on topic 'I was able to find your pants' that would cause it to be available if you had already handed the pants over or reverse pickpocketed the pants onto Gjalrunn.
- Fixed an issue that was preventing the golden pants from being removed from the player's inventory during The Naked Nord.
- Fixed Frenzy enchantment learnable from Chaoswielder incorrectly labeled as Fear.

Thanks for the response! And wow, I never even considered the possibility to install mods onto the Switch version of this game! What an expansive changelog, thanks for your continued effort on developing this mod!
