Here is what is being patched in this first post-launch patch. Due to redoing the video codecs this is a fairly hefty update, so apologies up front for that! 

• Main quest soft locking around the cave-based quests is fixed
• Ultrawide monitors now supported (tested at 2560x1080)
•  Video codecs have been changed to VP8 meaning they [i]should[/i] work without issue on Steam Deck
• Controls now lock when a full screen note or popup appears
•  Fixed bug where some weather effects continued in caves and underwater
