Hum, I've tried it and... is this version only like a "bugfix/hotfix" ? Don't see very much new things but there are some snowy screens which appears and nothing to do with it apparently (or I miss something)
TL;DR it is MOSTLY bugfixes, yes, but also a Performance Update and slight overhaul on some mechanics• The first floor TV can no longer trigger multiple game overs. (Thanks to IcyNinji for the bug report).
• Chloe should no longer be bald in nude cinematics while wearing the alpine beanie (Thanks to IcyNinji for the bug report).
• The bookcase and shallow grave will now properly remove wands from the loot pool.
• Added missing succubus/incubus sleeping animation.
• Fixed an issue preventing idle animations being reset when an effect gets removed (Thanks to MyahTG for the bug report).
• Minimap has been near completely rewritten and now performs much better on larger floors.
• The character inspector now displays the characters faction and active effects.
• Both keyboard and gamepad button input will now work even if the game is stuck in mouse input mode.
• Resource bar squares are now handled by a custom font and should appear identical on all operating systems.
• Fixed a bunch of bugs with poison gas instantly combusting near lava.
It may not appear wholly different for most (like myself), depending on how and on what system you play the game usually. But for some of the other users on Patreon these were apparently very intrusive issues that needed fixing.
