Visuals: A variety of graphical tweaks, fixes and optimisations.
Performance: A variety of CPU performance optimisations. Performance should also no longer gradually decay as you play through a level.
Balance: Pit exit portals open sooner.
Balance: Some arrows were shuffled between tiers - some powerful arrows were far too common.
Balance: Un-Nerfing Wrath of God arrow.
Balance: Quiver and Blood of the Lamb blocked as random enemy drops if you don't have any use for them. You will still see these as random world drops, even if you may not need them.
Bugfix/Balance: Fix for Tempest arrow to do headshots and hit ghosts in heart.
Feature: Divine Sight arrow very likely to give headshots but not guaranteed.
Feature: Grace of God leaves arrows undilated.
Tweaks: Reorganisation of the options menu. Chaperone on/off renamed to Front-facing/360 mode in order to reduce confusion, amongst other things.
Bugfix: Ensure input is definitely disabled when dead, during loading transitions, etc. Fixes a lot of weird bugs from accidentally opening the menu and other such things.
Bugfix: Fixing teleporting through walls in dungeons (including the wooden door, which serves no purpose. but thanks for trying).
Bugfix: No more lingering T-pose ice statues. Weren't they pretty though?
Bugfix: Fixing personal space stuff when using free movement - enemies should no longer be swinging at you when they're already up in your face, but instead do so from a proper, respectful distance. As a happy side effect, you no longer need to restart your run if you want to toggle free movement on/off.
Bugfix: Fixing Purgatory + not progressing seed and difficulty during challenges.
Bugfix: Fixing Pits spawn location, they would sometimes overlap with the world.
Bugfix: Changed Pit portals so they behave the same as boss entrance portals (responding only to teleport arrow and knife so that you don't accidentally enter by moving too close).
Bugfix: Fixed going into demo mode or challenges breaking continue points.
Bugfix: Fixing Azure Fury arrow not doing proper damage when shot at too close of a distance.
Bugfix: Ensure arrow selection shows up when grabbing an arrow pickup even if the shield is up.
Bugfix: Removed the Purgatory Mastery achievements that used to unlock the gateways, as they no longer exist.
Bugfix: Possibly fixed sky going black after exiting a Pit.
