PC version history


 * See upcoming features for future updates.

A list of changes made in each update. A (?) denotes that the info there is guesswork, and possibly incorrect. Known bugs in the latest versions are listed here.

1.2
After announcing on 21 February 2012 that Terraria development had ceased, Redigit hinted on 23 January 2013 at a possible update. Since then, the developers have spoken openly about various details of a 1.2 update. They have stated that the 1.2 update will be larger than the 1.1 update (the one that introduced Hardmode). 1.2 has been released on October 1st. .

The following information is mainly based on various statements and screenshots released on the Terraria forums, IRC channel, and Redigit's official Twitter account. It is preliminary information and might not be completely accurate.

New bugs

 * colspan="2" |
 * If you try to place a Music Box on a Table or Wood Platform, it will duplicate itself repeatedly, spamming the ground.
 * Sometimes statues drop Armor Statue instead of correct one. This appears to happen when the player does not have inventory space remaining, while having an Armor Statue in their inventory.
 * If you attempt to hook a block with Dual Hook that has water above it, it will not let you stick to it. If you try it with two blocks below water, you will be able to stick but will start to drown for some unknown reason.
 * There's inconsistency with Hallowed armor's headpieces' names in game. Hallowed Mask is crafted with Helmets and is a melee piece, and Helmet is crafted with Masks and is a ranged piece.
 * Sometimes half of the Mimic can appear to be inside a block when the Mimic spawns next to a wall.
 * The Jungle Theme starts to play if there is a large amount of potion herbs nearby.
 * Occasionally, summoning bosses with items such as Suspicious Looking Eye,Worm Food, etc. will not make the boss appear and will consume the item. This is confirmed to happen in Multiplayer and Singleplayer.
 * Right clicking on the Music Box while in your inventory will cause the game to crash.
 * It is impossible to free the new captive NPCs in single player if autopause is turned on.
 * It is possible in Multiplayer to duplicate armor, when it is placed on Mannequin and then rapidly removed by more than one player.
 * The Diving Helmet does not extend underwater breathing.
 * You can summon Skeletron Prime again after killing only his Prime Cannon, without having to kill his head.
 * Most underwater Cursed Torches will vanish upon map reload.
 * If the server command to settle liquids is used all Cursed Torches in water will act like they are normal torches under water and break off of the surface they're attached to.
 * Chaos Elementals can spawn in non-Hardmode worlds, if Pearlsand or Pearlstone blocks are placed in the Cavern layer.
 * If you try to place a Music Box that has already recorded a song on a Table in Single Player (but not Multiplayer), it will instead drop on the ground along with up to 6 copies of itself.
 * Hitting a Music Box with the Ice Rod will cause the box to turn into a dropped item, then it and all other music boxes, when activated on the ground, will cause only the stem of the note to light up, and when holding down right click on the box, it will rapidly turn the box on and off while making your vanity items dissapear (though still equiped). The boxes will still work as normal.
 * The Wall of Flesh may grab you and give you "The Tongue" condition, but will never let go. It will continue to rise vertically, until it reaches the top of the map. From what has been seen, there is no way out of this.
 * If the Wall of Flesh kills you, a glitch may occur where it can't be re-summoned and getting close to the Underworld will automatically give you the Fright status. It will also happen if you quit to the title screen while fighting the boss. To fix this, you must exit the game entirely and restart (just exiting the world without exiting the game won't work).
 * Sometimes, if the Wall of Flesh mouth gets caught in a block (because the blocks are too steep for the wall to avoid them) and your character gets The Tongue debuff, rarely, your character will get stuck in those blocks for a while until the wall shoots another tongue.
 * If you drop a Guide Voodoo Doll in lava far enough away that you cannot see the lava it lands in, the Wall of Flesh may summon without eyes, mouth and The Hungry and can't be beaten. Any Player(s) behind the invincible Wall will instantly be killed, As if they were using a Magic Mirror.
 * Sometimes the Wall of flesh doesn't drop a Pwnhammer.
 * Sometimes Wall of Flesh might get out of the map limits and continue running towards emptiness.
 * If there is a server the Wall Of Flesh fighter (player who tries to kill WoF) might die then all the players will continuously die.
 * On some worlds, you can't summon Wall of Flesh again after you defeated it.
 * Boulders always roll to the left, unless there is no space for it to go left.
 * NPCs will jump on top of the boulder like a platform, and hang off it as if they were floating.
 * If you're on top of a rolling boulder you will take the damage.
 * Crystal Shards can grow to the right, left or below a Pearlstone, but never above one, unless it is supported by a separate pearlstone block. The game's code and graphics indicates that this should be able to happen.
 * If the player has a Fairy out and saves and reloads a world the Fairy may have a different color.
 * The Fairy Bell can be used when you have less maximum mana (0 or 20) than required (40).
 * Size of the impassable borders that outline map is based on the current Lighting style, so if you change it by pressing F9 you can have additional space.
 * When putting a chest on the Ice blocks, if kept on long enough, will cause the blocks to be permanent until the map is unloaded. This can also cause a glitch where you are able to get unlimited chests.
 * Inactive blocks still support Sand, Ebonsand, and Pearlsand.
 * The notes produced by the Magical Harp pass through single block walls the same way flails currently do.
 * If you step into lava and catch fire while in water the Neptune's Shell transformation cancels and stays canceled until you leave and re-enter the water possibly leading to you drowning while still on fire.
 * Setting up a closed Pump system (inlet to outlet back to inlet), will create infinite liquid as long as the intake started completely submerged.
 * Santa Claus will spawn and instantly die when the Holiday event is over.
 * Occasionally, Skeletron Prime's head disappears randomly, ending the fight.
 * When Snow Balla kills you with his projectiles, the death message states you were killed by sand, like if you were hit by an Antlion.
 * If you start running with Spectre Boots from far enough away, you can fall down a 1 block wide hole if you hit a wall.
 * The Tombstone can be abused to spawn bosses without wasting the summoning item. If a player has a boss summoning item (such as the Mechanical Worm) chosen in his hotbar and right clicks a tombstone, he can click on close. This will summon the boss without wasting the item. Multi-player only.
 * If you have Wires in the ammo slot, the ones that you pick up will form a new stack in your inventory instead of stacking with the ones you already have. It is probably related to the lack of "Ammo" tag in item's tooltip.

 * Multiplayer latency/lag has greatly increased, even on local computer. Hitting mobs will cause them to knockback-teleport back by lag. This also applies to other monsters than Slimes.
 * Mob spawnrate has been decreased. Sometimes mobs may not spawn at all. This happens on fullscreen and high resolutions (1920x1080 for example).
 * Non-numeric characters may be entered to the server port, such as alphabets.
 * Worm Food and other summoning items will take effect in their location, even when not used.
 * High resolutions may cause graphical menu glitches during startup.
 * High resolutions may cause a black bar to appear in the background, as seen in this screen shot.
