Tear flags are now represented by the BitSet128 data type, this was a necessary change due 64 bits no longer being enough to hold every tear effect in the game.If Tainted is set to true, only matches tainted characters.If Tainted is omitted or set to false, only matches non-tainted characters.
quality: Sets the quality of this item (0 to 4, where 0 is the lowest quality and 4 is the highest).persistent: If set to true, temporary effects tied to this item persist between rooms.hidden: If set to true, cannot be obtained in game unless explicitly spawned or given to the player.
passivecache: If set to true on an active item, evaluates the player’s stats on pickup like a passive item rather than when using the item.chargetype: Can be set one of the following 3 values: normal (recharges on room clear), timed (recharges over time), special (never recharges automatically, cannot be recharged by batteries or item effects).
Mod save data is now stored separately in a "data" folder, meaning that updating or unsubscribing from a mod will no longer cause its save data to be wiped.This directory can be easily accessed by right clicking The Binding of Isaac: Rebirth in the Steam library, then clicking on "Properties", "Local Files", and finally "Browse.".Mods are now stored in a "mods" folder in the same directory as the rest of the game files.
