- Added a "Spirits Abyss 100%" achievement for getting all other achievements. If you previously had them all then just boot up into the title screen and the 100% achievement should drop.
- Added an Achievements screen to the Grimoire Compendium where (you can probably guess!) you can view all of the game's achievements.
- Added a helpful tip when playing a Co-Op game for the first time explaining the Twin can teleport by pressing the Item button.
- Increased the chance for a crate to contain an item or be booby trapped if you already have a lot of bombs.
- Sullenwoods: During a Lexicanium Hunt, Hanged Haunters will no longer appear and Hang Hauntlings will always drop a Restless Heart upon death (and now have a small chance of doing so in other game modes).
- Runic Mineraliser: Reduced the extra bonus swing to just a free swing as in some levels it could hugely increase your bomb count.
- Telemond Time Trial: Removed the imp as he's rather annoying.

//bug fixes
- Delete Save menu: Deleting all data will now restart the game (otherwise it can cause crashes in the current run). Resetting the settings wasn't setting the sounds to the default level.
- Dropping down from a ledge would instantly activate the Seraphus Feather and Selestious Talisman items.
- In the Frostal Fields region one of the room sections had a chance of creating a chest/crate inside of a wall.
- The Olden Trial sub-stage rewards weren't conforming with the Seed and could give you a passive item you already had.
- Getting killed when the Boss also dies would cause a crash.
- Getting hurt on the same frame as the Lexicanium Hunt Boss was killed would cause a crash.
- Minesmithers: Their bomb count wasn't reducing when hitting vault chests and similar objects (eg blocked doorway rocks).
- Getting the Curseify Hearts curse wasn't turning restless hearts into cursed hearts.
- A crate containing a Seraphus Feather would teleport it downwards through the floor.
- The Binocularscope wasn't working in Co-Op mode.
- The Snow Globe had the wrong short description.
- The Game Over timer would continue if you killed yourself via the Escape menu's Seppuku option.
- The Rusty Key can now be used to unlock the Sinners Chambers domain region.
- The Wally Vomiter can now be hurt by the player's orbitals and item projectiles.
- The ambient warp vortex sound would continue endlessly in some circumstances (eg when using a Flute or quitting the game mode when close to one).
- Fixed a few game over death messages which were attributed to the wrong enemy cause of death.
