Binding of Isaac Downloadable Content is now available, the massive update called The Binding of Isaac Repentance was released on March 31. Here are the patch notes for what all has been updated, changed, and new. Are you ready to dive into the new features this rogue-like has to offer?

The Binding of Isaac Repentance v4.0.4 Patch Notes

General fixes

Vengeful Spirit deals a lot more contact damage, before it was dealing much less than intended.

Hostile enemies spawned glitch items no longer deal instant damage, so the player gets a small amount of time to get away from them.

Fixed Vanishing Twin being able to turn into Dark Esau.

Fixed Locust of War + Brimstone Bombs being able to damage the player when spawned by Cricket Leg.

Fixed a bug which caused the first two floors of the alternate path to always share the same variant, making it impossible to see both Downpour and Dross in the same run.

General modding changes

Mods are now stored in a "mods" folder in the same directory as the rest of the game files.

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...".

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.

The name of the subfolder used to store save data is determined by the "directory" property in metadata.xml.

Added a loading screen that appears when installing or updating mods from Steam Workshop.

XML changes

Players (players.xml).

Added the following properties:

broken: Number of broken hearts this player begins with.

pocketActive: Gives this player the specified starting active item in the pocket item slot.

birthright: The unique description that should be displayed when this character picks up Birthright.

bSkinParent: If present, marks this character as the "tainted" version of the regular character that bears the specified name.

Usually, this should be set to the same name as the character, unless the tainted and regular version of this character bear different names.

If there is no regular character to attach to, this character will not be available in the character selection menu.

hidden: If set to "true", hides this character from the character selection menu.

Custom coop selection graphics can be set for all modded characters by supplying the following animation file (non-tainted characters only):

"content/Coop Menu.anm2": Must contain one animation per character, each animation must bear the same name as the character it was made for.

Custom menu graphics can be set for tainted characters by supplying the following animation files:

"content/CharacterMenuAlt.anm2".

"content/CharacterPortraitsAlt.anm2".

"content/Death Screen Alt.anm2".

"content/Coop Menu Alt.anm2".

"content/CharacterMenu.anm2" and "content/CharacterMenuAlt.anm2" no longer require a "Background" layer as the game now renders the paper background automatically.

Items (items.xml).

Added the following properties:

shopprice: Sets a custom shop price for this item.

initcharge: Overrides the initial charge for this item (this can be used for active items that do not start with a full charge).

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).

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.

hidden: If set to true, cannot be obtained in game unless explicitly spawned or given to the player.

persistent: If set to true, temporary effects tied to this item persist between rooms.

quality: Sets the quality of this item (0 to 4, where 0 is the lowest quality and 4 is the highest).

tags: Adds one or more tags to this item (see items_metadata.xml for reference).

Lua changes

Added a new include() function which acts like a "raw" version of require() and will always load the specified file even if it was loaded before.

Fixed the spelling of EntityPlayer:GetMaxPocketItems() and EntityPlayer:DropPocketItem().

Previous spellings are still present for backwards compatibility but should no longer be used.

Sprite:SetFrame() can now be called with only an int argument, this will adjust the current frame for the current animation without stopping it.

Vector multiplication is now commutative (number * vector is a valid operation) and supports element-wise vector by vector multiplication.

Color(R, G, B, A, RO, GO, BO) has been updated:

Only the first three arguments (R, G, B) are required, A defaults to 1 when omitted.

The offset parameters (RO, GO, BO) default to 0 when omitted and are now in the 0-1 range instead of 0-255 for consistency.

Mods that use this feature will need to be updated.

Added constants Vector.Zero, Vector.One and Color.Default for convenience purposes.

Updated Isaac.GetPlayerTypeByName(string Name, boolean Tainted = false).

If Tainted is omitted or set to false, only matches non-tainted characters.

If Tainted is set to true, only matches tainted characters.

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.

Most AB+ mods should be backwards compatible, however due to a limitation from Lua, expressions such as "Tear.TearFlags & TearFlags.TEAR_POISON == 0" no longer work correctly.

This can be quickly fixed by either replacing "==" with "<=", replacing 0 with TearFlags.TEAR_NORMAL, or using the convenience functions below.

The following convenience functions have been added:

void Entity_Tear:AddTearFlags(BitSet128 Flags).

void Entity_Tear:ClearTearFlags(BitSet128 Flags).

boolean Entity_Tear:HasTearFlags(BitSet128 Flags).

void Entity_Bomb:AddTearFlags(BitSet128 Flags).

void Entity_Bomb:ClearTearFlags(BitSet128 Flags).

boolean Entity_Bomb:HasTearFlags(BitSet128 Flags).

void Entity_Laser:AddTearFlags(BitSet128 Flags).

void Entity_Laser:ClearTearFlags(BitSet128 Flags).

boolean Entity_Laser:HasTearFlags(BitSet128 Flags).

void Entity_Knife:AddTearFlags(BitSet128 Flags).

void Entity_Knife:ClearTearFlags(BitSet128 Flags).

boolean Entity_Knife:HasTearFlags(BitSet128 Flags).

Updated EntityProjectile:

Added:

void ClearProjectileFlags(int Flags).

boolean HasProjectileFlags(int Flags).

MC_PRE_SPAWN_CLEAN_AWARD, MC_PRE_NPC_UPDATE and all MC_PRE_xxx_COLLISION callbacks will now only skip remaining callbacks when returning a non-nil value.

MC_GET_SHADER_PARAMS will now only skip remaining callbacks when returning a table.

Updated arguments passed to MC_USE_CARD (int CardId, EntityPlayer Player, int UseFlags).

Updated arguments passed to MC_USE_PILL (int PillId, EntityPlayer Player, int UseFlags).

Updated arguments passed to MC_PRE_USE_ITEM (int ItemId, RNG ItemRng, EntityPlayer Player, int UseFlags, int ActiveSlot, int CustomVarData).

Updated arguments passed to MC_USE_ITEM (int ItemId, RNG ItemRng, EntityPlayer Player, int UseFlags, int ActiveSlot, int CustomVarData).

If a table is returned instead of a boolean, the following fields can be set to a non-nil value for extra functionality:

Discharge: Determines whether the item should be discharged or not after being used.

Remove: Determines whether the item should be removed from the player or not after being used.

ShowAnim: Plays the default use animation if set to true (equivalent to simply returning true in AB+).

Updated PlayerTypes.ActiveItemDesc.

Added:

int TimedRechargeCooldown: Number of frames before an item with a timed cooldown can recharge again (used by Spin To Win to pause its recharge after fully discharging it).

float PartialCharge: How close the item is to gaining another charge (0-1 range, used by 4.5 Volt).

int VarData: Holds extra information for some active items (such as the number of uses for Jar of Wisps).

Removed:

boolean Lock.

Updated EntityPickup:

Added:

int OptionsPickupIndex: Any non-zero value causes the item to form an option group with any other item with the same OptionsPickupIndex value.

When an item belonging to an option group is picked up, all other items belonging to the same group disappear.

0 is the default value and means the item doesn’t belong to any group.

Removed:

boolean TheresOptionsPickup: see above.

Updated GridEntity:

Added:

RNG GetRNG().

The object returned from this function is now a reference rather than a copy.

Sprite GetSprite().

Same as above.

Removed:

RNG RNG.

Sprite Sprite.

Updated Sprite:

Added:

string GetAnimation().

string GetOverlayAnimation().

Updated EntityPlayer:

Added:

void ChangePlayerType(PlayerType Type).

void AddBrokenHearts(int Num).

void AddRottenHearts(int Num).

int GetRottenHearts().

boolean CanPickRottenHearts().

void AddSoulCharge(int Num).

int GetEffectiveSoulCharge().

void AddBloodCharge(int Num).

void SetBloodCharge(int Num).

int GetBloodCharge().

int GetEffectiveBloodCharge().

EntityPlayer GetMainTwin().

EntityPlayer GetOtherTwin().

boolean TryHoldEntity(Entity Ent).

Entity ThrowHeldEntity(Vector Velocity).

EntityFamiliar ThrowFriendlyDip(int Subtype, Vector Position, Vector Target = Vector.Zero).

EntityFamiliar AddWisp(int Subtype, Vector Position, boolean AdjustOrbitLayer = false, boolean DontUpdate = false).

EntityFamiliar AddItemWisp(int Subtype, Vector Position, boolean AdjustOrbitLayer = false).

void TriggerBookOfVirtues(CollectibleType Type = CollectibleType.COLLECTIBLE_NULL).

EntityFamiliar AddSwarmFlyOrbital(Vector Position).

int GetNumGigaBombs().

void AddGigaBombs(int Num).

CollectibleType GetModelingClayEffect().

void AddCurseMistEffect().

void RemoveCurseMistEffect().

boolean HasCurseMistEffect().

boolean IsCoopGhost().

EntityFamiliar AddMinisaac(Vector Position, boolean PlayAnim = true).

The Binding of Isaac Repentance v4.0.0 Patch Notes

General Changes

Coop can now be played with multiple, separate characters instead of babies. If played with multiple characters, bosses will drop multiple items.

Greed Mode now features floor alts (Burning Basement, Necropolis, etc).

Challenge room waves are now randomized, and each floor features unique waves (previously they were shared for every alt floor in a chapter).

Small boss rooms and small miniboss rooms have been disabled.

Rooms with portal enemies now only appear in The Void.

Rooms with spikes directly next to the entrance have been adjusted. The spikes are either moved away from the door or blocked off.

Adjusted the appearance rate of many special rooms to be more balanced (the black poop super secret room is now rarer, for example).

The item tracker now includes a "mini" option, allowing for more items to be displayed at once.

Black hearts no longer pause the game with an animation when lost. New, less intrusive effects have been added for them.

The tears stat on the HUD now displays as "tears per second" (previously displayed delay between tears in frames).

The range stat on the HUD now displays the amount of effective range in tiles (this also fixes misleading cases like Mini Mush/Kidney Stone).

Devil/angel chances on the HUD have changed to display the chance the respective deal will appear (previously displayed the chance for an angel deal to replace a devil deal).

Duplicate items now show up on the item tracker/pause menu/game over screen.

Smelted/gulped trinkets now show up on the item tracker.

It is now possible to pick up two of the same trinket (if it was duplicated). Effects can stack.

Sacks can now be sold in shops for 7¢.

Items/mechanics that damage red hearts first now ignore eternal hearts instead of removing them.

Bombs now flash corresponding to their detonation timer, instead of exploding without warning.

Curse of the Maze now avoids teleporting players to already explored rooms.

Brightness around players has been increased in order to aid visibility in Curse of Darkness on lower gamma settings.

The pixelation visual effect (used by Retro Vision and stage transitions) has been reworked, and is generally less blurry/painful to look at.

Retro Vision now lasts a set amount of time instead of going away and returning at random intervals.

Mom’s Dressing Table has been moved from the starting room to bedrooms.

Spider Mod now features color coded health bars and more accurate damage information.

Enemies now die upon reaching zero health. Previously, enemies needed to reach negative health to die. This mostly improves the lethality of items that deal fixed damage.

"Moldy Bread" has been renamed to "Midnight Snack". Pickup quote changed to "HP up".

Rooms with water in them now automatically extinguish fireplaces. Most Flooded Caves rooms have fireplaces pre-extinguished, and the Flush item will extinguish fireplaces in the room upon use.

"Delete Save" confirmation dialog now defaults to "No" instead of "Yes".

"goto" console command now accepts the prefix "x" for special rooms from the current stage.

Many minor tweaks and improvements to various pickup animations.

Slightly tweaked enemies with Larry Jr style behavior to have smoother movement.

Chubber’s chomping maggot projectile now dies when the Chubber does, instead of returning to the original firing position and disappearing.

If pits are near the trap door that spawns after a boss, they will now be automatically filled and become walkable. This prevents situations where a trap door could block off devil/angel doors.

Challenge room doors re-close if Isaac no longer meets their entry conditions while in the adjacent room.

Removed jittering from Technology lasers and adjusted hit detection to be more accurate.

Removed Greed Gapers from treasure rooms.

Removed the forced delay between Portable Slot uses.

Dingle now shoots poop shots instead of blood shots (aside from the red champion), to be consistent with other poop enemies.

Ulcers now fire blood shots in arcs instead of in straight lines.

Challenge rooms no longer interrupt the floor music theme pre-ambush.

Minibosses now use the ambush theme instead of the regular boss theme.

Red Candle flames, and flames spawned by certain enemies, now play a sound and animation when extinguished.

Head costumes now deform along with the player’s head when firing charged attacks, such as Brimstone.

The decapitated body from Pinking Shears now uses the player’s costumes.

Floor music layers can now play if the room’s enemies’ total HP reaches a certain threshold (previously required a certain amount of enemies in a room to play the music layer).

Light beams (such as Crack the Sky beams or the Cathedral’s entrance beam) and many tear effects now properly light up dark rooms.

Homing tears now target enemies much more reliably.

Timed recharge items now recharge immediately upon room clear, and from certain item effects (such as Habit or Charged Baby).

9 Volt and Jumper Cables no longer play the "item ready" sound effect when only granting partial charge.
