This update contains multiple smaller bug fixes for example some bugs related to pit respawns or the game stats display and several changes to the overall game balance.
Player damage has been changed slightly so you should do a bit more damage on average.
Some monsters had their health and damage values changed according to the player damage changes.
Teleportation Wings got updated to make you fast travel to more locations too.
Overall these changes should result in an overall better experience for the player.
