I like to see change history and Spooky hasn't provided it so I looked at the crawled versions of the page and grabbed what was available
Patch Notes:
v2024.01.07.12
Updates:
Character descriptions in Character Select updated
Fred: Begins with a virtual lock for Mystery Machine Multiball
Shaggy: Awarded 2x trap door ball saves when SD standing targets completed
Scooby: Starts each ball with one of the Ruh-Roh outlanes lit
Daphne: +5 seconds to all ballsave timers
Velma: Requires 2 fewer clues to qualify a case
Game starts with your characters mode qualified
Secret skillshot value increased from 20k to 100k
Spinner SFX play in ALL modes, instead of only base mode
Gratuitous Space Kook Laughter
Tournament Mode setting added
Qualified villain mode synchronizes between co-op players
Fixed bug that crashed game when player drains on 7th villain
Combo system now un-lights the most recently hit shot in the combo sequence
Tournament mode now correctly replaces all extra balls with points.
Shoot the blue habitrail thrice in rapid succession to start a hurry up at the upper passive sling during base gameplay. Completing the hurry up awards a jackpot, unless a bookcase topper is installed, in which case, the Haunted Topper video mode becomes lit at the left orbits
Co-op Mode:
Hold start button for 4 seconds when starting the game (or at first character select screen) to enter Co-op mode. Scores and the majority of game states will synchronize across all players.
(Co-op scores are not displayed on the High-Score list yet. This will be added in a future update)
Green Ghouls hurry up:
Slings in base mode advance on-screen clock. When clock strikes midnight, each green ghoul becomes lit at the inlanes. Rolling over either inlane spawns a ghoul who will roam across the playfield. Shoot the ghouls for points! Shoot both ghouls when they overlap at the same shot for a jackpot! If a ghoul makes it across the playfield without being hit, you’ll lose progress toward character modes that haven’t been qualified yet.
v2023.10.28.23
Updates:
Combo System! Shoot character orbits in rapid succession to build combos! Creating combos with unique permutations of characters awards “Let’s split up” combos. (Info screen to track progress to come)
Pirate Henchmen; Cutler bash will now start Pirate Henchmen mode after Captain Cutler Multiball. You must knock down both henchmen drop targets to re-qualify Captain Cutler Multiball.

v2024.03.11.11
Release Notes:
Would Have Gotten Away With It Wizard Mode
Visit all Villain Modes to qualify Wizard Mode at Mystery Machine
Phase 1: Werewolf, Frankenstein, and Dracula subphases will begin one at a time (on-screen timer shows time before next subphase starts). Each subphase adds a ball, requires a number of shots to be completed, and lights a lock at the Mystery Machine once that subphases shots have been completed. This phase ends when all balls have been drained or locked. If at least one ball has been locked, Phase 2 begins when Phase 1 ends.
Phase 2: The monsters are back! This phase begins with multiball, (2 balls, plus one ball for each successful lock in Phase 1). First, accumulate the required number of switch hits (remaining hits displayed on-screen; all playfield switches count), at which point, one of 7 Monster Jackpots will be lit randomly. Collecting the jackpot will add a ball if there are fewer than 3 balls in play, and will reset the switch hit counter. Repeat the process to collect all 7 Monster Jackpots and complete the mode!
