Mojang announced the Bundles of Bravery drop for Minecraft at the end of September 2024. This small update focused on the addition of bundles, a feature announced nearly four years ago, and Hardcore mode for Bedrock Edition. Since Java Edition already had Hardcore mode, fans expected the update to be a light-hearted one.However, Minecraft Java 1.21.2 has plenty of exciting features and changes outside of bundles for players to be excited about. For example, Mojang added baby variants of dolphins, squids, and glow squids, which have been available in Bedrock Edition for a long time.Mojang also added more Bedrock-exclusive features like two banner patterns: Field Masoned and Bordure Indented. Let's go over the complete patch notes to find out what's new and changed in the Minecraft 1.21.2 update for Java Edition.Minecraft 1.21.2 update patch notesNew FeaturesAdded BundlesBundles are here (Image via Mojang)BundlesA Bundle is an item that can pack different items together into the same stackA Bundle only fits one stack (usually 64 items) but it can be a mixture of many different item typesYou can insert items into a Bundle directly in the inventoryBundles have a tooltip that shows the items insideIf a Bundle has less than 12 item types inside, the tooltip will show all of themOtherwise, the tooltip will show the top three rows of items (at least 8 item types) and the others will be hidden belowYou can select any of the visible items to pull out of the BundleRight-click to take the first itemUse the scroll wheel to select a different item, then right-click to take itWhen selecting an item to remove, the Bundle icon shows that item poking out of the BundleWhen holding a Bundle in hand, you can empty items onto the ground by right-clicking or holding right-clickThe Bundle is crafted with one String above one LeatherThe controls have changed from the original prototype:Use left-click to put an item into a BundleUse right-click to remove the top item type from a BundleWhen the Bundle tooltip is visible, use the mouse wheel to select a different item type, then use right-click to remove itChangesEnabled hardcore mode for RealmsUpdated the world creation screen for RealmsTrial Chambers have been updated with new variationsAdded baby versions of Dolphins, Squids, and Glow SquidsAdded Salmon variantsSneaking while bouncing on a Slime Block will no longer cause fall damageTweaks to existing Blocks, Items and EntitiesThrown Ender Pearls now load and tick

Banner Patterns: Field Masoned, and Bordure IndentedThe distance that Bees fly as well as the cooldowns between Bee behaviors have been tweakedRaider spawn logic has been updatedSmithing Template items are now named after their template type instead of the generic "Smithing Template" nameThey instead specify that they are a Smithing Template through a subtitle in the hover textEquipping a Carved Pumpkin on your head now removes the player marker from other players' mapsVarious items and blocks have had their assigned rarities changedIntroduced new accessibility featuresThe game will now limit the maximum frame rate when it is minimized or when the player is AFKA new video setting is introduced to configure this behaviorImprovements to the game's performanceAdded language support for Tzotzil, Belarusian (Latin), and High NorwegianThrowing items out of your inventory very quickly in creative mode is now throttledRealmsNow uses the normal, fully-featured world creation screenEnables game rule customizationEnables data pack customizationThe game mode for the last active world on a Realm will now be visible on the main Realms screen if applicableHardcore ModeHardcore mode is now available in RealmsIt is accessible when creating a new world or recreating an existing oneTweaks to Blocks, Items and EntitiesWolves can now also be fed Cod, Cooked Cod, Salmon, Cooked Salmon, Tropical Fish, Pufferfish and Rabbit StewBats can now spawn at any height, not just below sea level, as long as it is dark enough and there is a solid block to spawn onBreeze no longer have a minimum distance required to attack a targetThe portal cooldowns of vehicles and projectiles have been tweakedAfter using a Nether Portal, Minecarts and Boats now only need to leave the portal for 0.5 seconds to use a portal again (down from previous 15 seconds)After using a Nether Portal, projectiles such as Ender Pearls and Arrows now only need to leave the portal for 2 ticks to use a portal again (down from previous 15 seconds)Projectiles such as Arrows, Tridents and Fishing Bobbers now bounce off the world border if hitBeing killed by a Mace smash attack now shows a new death messageAdded unique block sounds to the Monster Spawner blockEnchanted Shields now have the same reduced glint as enchanted armorItems that convert to another item after consumption will no longer do so in creative modeFor example, a Honey Bottle will no longer add a Glass Bottle to your inventory when consumed in creative modeSuspicious Stew recipes are now shown in the Recipe BookShulker Box coloring recipes are now shown in the Recipe BookShulker Box and Bundle coloring recipes no longer work when trying to apply a Dye to an item of the same colorTrial ChambersAdded new variations to the hallways, including "Encounters": Short challenges leading to a larger chamberBeds in intersections now have their colors randomizedReplaced the empty Chests at the entrance of chamber with a Hopper and BarrelNew Mob VariationNew baby mobs (Image via Mojang)Added baby versions of Dolphins, Squids, and Glow SquidsSquid Spawn Eggs will only spawn adult SquidsThere is a 5% chance of Squids spawned in groups in the wild to be a babySalmon may now spawn as Small, Medium (current size), or LargeEnder Pearl Chunk LoadingEnder pearl chunk loaders are here (Image via Mojang)Ender Pearls now ensure that the chunk they are in or travel into is always loaded and tickingThey also load chunks when crossing to a new dimensionThis ensures that Ender Pearls can always land, and makes cross-dimensional Ender Pearl travelling more predictableEnder Pearls now unload when a player logs out, and reappear whenever that player logs back in, similar to how ridden entities currently behaveBanner PatternsEach Banner Pattern item now includes their pattern type in their name instead of as a subtitleUnique item textures have been added to better distinguish each pattern typeThe following Banner Patterns have been added:Field MasonedCrafted with Paper and BricksBordure IndentedCrafted with Paper and VinesThe Bricks and Curved Border patterns in the Loom can no longer be accessed without the above Banner PatternsBee BehaviorBees now wander around randomly for less time after exiting a nest/hiveA Bee with a known nest or hive will now stay closer to it, reducing the distance it travels and reducing the risk of getting lostSignificantly increased the amount of time a Bee can take to return to a known nest/hive before it gives up trying to return homeBees are now a lot less likely to get stuck when on corners or when close to a nest/hive they are trying to return toBees are also now a lot less likely to try and pathfind to a flower that it cannot reachRaider SpawningA triggered raid will no longer start if the Raiders cannot find a place to spawn within a reasonable distance of the village they are trying to raidIn order for a Raid to start, Raiders must now find a place to spawn no more than 96 blocks vertically above or below the Village centerIt is now much less likely for Raiders to not find a valid place to spawn when raidingUser InterfaceThe Recipe Book now repeats the last selected recipe when a "selected" key is pressed (space or either enter key)Updated slot highlight in the UI so that the item texture has better visibilityThe previous textures have been added to Programmer Art resource packTweaked air bubbles UIAdded an empty state for air bubbles along with a wobble when the player is drowningAdded a popping sound when the bubbles pop in the UIRarityRarity is a set of categories which determine the color used to display the name of an item or blockIt has no gameplay impact, but is used to signal how difficult something is to obtainBy default, unless specified otherwise, all items and blocks have a rarity of Common which displays their name in the color whiteWe have re-evaluated the rarity of all items and blocks in the game to more accurately reflect the current challenge of obtaining them, given the following guidelines:Items and blocks become more rare depending on the following factors:The chance of finding it in a loot table, including mob dropsThe amount of travelling required to obtain itThe difficulty of any obstacle which must be overcome to obtain itThe possible amount of that item or block which exists in the worldAny item or block which can be crafted must inherit the highest rarity of its crafting ingredientsFor example, a Mace has an Epic rarity because one of its ingredients (the Heavy Core) has an Epic rarityLikewise, any crafted item which has only Common crafting ingredients must also be CommonThe lists below detail the items and blocks which have changed to that rarity categoryCommonEnd CrystalGolden

Gameplay features:Creaking will activate if a surivival or adventure mode player is within 12 blocks of it and looks at itCreaking stays active while there is a survival or adventure mode player within 32 blocks of itAn activated Creaking will not move if a survival or adventure player is looking at itCreaking is invulnerable to damageCreaking has fire resistanceWhen hit by players, a particle trail is shown between the Creaking and the Creaking Heart block it is connected toWhen the Creaking Heart block that the Creaking is connected to is destroyed, the Creaking is removedIs not affected by light levels but spawns and despawns based on the day/night cycleCreaking cannot enter BoatsCreaking spawned from a Creaking Heart can not go through portalsThe Creaking Spawn Egg will spawn a Creaking mob that is not connected to a Creaking Heart. This form of Creaking:May also be spawned through commandsWill persist through day and night, and loads and savesIs fire-resistantTakes damage from attacks and other damage sourcesHas one point of health (half a heart)A Creaking summoned from the Creaking Heart cannot be spawned with a spawn egg, nor can it be named with a Name Tag or summoned with commandsIt can only exist as a part of the Creaking Heart blockPlayers wearing a Carved Pumpkin on their head can look at Creaking without it freezing in placeCreaking HeartA Creaking Heart is a “living” block generating in Pale Oak trees, covered on all sides by Pale Oak wood logs. It can spawn a Creaking mob when it is nighttime, and it is placed between two correctly aligned Pale Oak Logs.Is active during the night and dormant during the daySends a trail of particles towards the connected Creaking when the Creaking gets hit by the playerWhen Creaking Heart block is destroyed, the connected Creaking is removedComparators attached to the Creaking Heart block will output a signal strength dependent on the distance to the connected CreakingNew system for Pale Garden ambient soundsAmbient sounds in the Pale Garden biome do not come from the biome settings, but are generated by blocks found in the biome.Pale Hanging Moss emits subtle atmospheric sounds when it is attached to Pale Oak Logs and Pale Oak LeavesCreaking Heart block emits a set of eerie sounds when it is active during the night and surrounded by Logs on all sidesRedstone ExperimentsExperimental redstone features (Image via Mojang)Added a new Experiment containing various Redstone-related changes.Redstone WireThe performance impact of Redstone wire (connected blocks of Redstone Dust) has been improvedRedstone wire now only triggers block updates on blocks that may receive power from the wireBefore a line of wire causes block updates, the new signal strength of all connected wires is setThe update order around Redstone wire has been changedThe aim is to make wire work the same, independent of position and global orientationWhen possible the order is deterministic based on the context the updates are caused inWhen there is not enough context to fully determine the order, the rest is picked at randomDeveloper's note: We know that randomness in Redstone is usually unwanted. We've used it here because we've made things deterministic whenever it makes sense, and sometimes it just doesn't make sense - and we don't want some hidden state (like location-based hashes!) determining the order and making machines work differently at different coordinates or in different orientations.Order in Which a Line of Wire ChangesWhen a line of wire turns on, the wires closer to the power source will cause block updates firstWhen a line of wire turns off, the wires closer to where the power source was, will cause block updates firstWhen two wires have the same distance to the power source, the one to the left in the direction of travel updates firstIf there is not enough context to know the direction of travel (when the wire was powered from above or below), the side to update first is picked at randomBlock Updates Around a WireThe order in which blocks around the wire update is based on the direction the wire received an update fromThe order of the updates is: back, front, left, right, down, upWhen the updates are further distributed through solid blocks, the same order is applied thereKnown IssuesAs this experiment only changes Redstone wire, interactions with other components may not always act as expected, especially when it comes to update orders.The removal of excessive neighbor updates around wire affects behavior of Quasi-Connectivity based contraptions. We plan to address these issues at a later point.Minecart ImprovementsExperimental minecart changes coming (Image via Mojang)Minecarts are getting updated for the better:Movement ChangesMinecarts will articulate their movement better when going fast, riding on the rail all the timeMinecarts will now smoothly turn along with the track and are less likely to halt or derailMinecarts can now jump betterThey keep their vertical momentum when the track ends with a slopeMinecarts will tilt to visually articulate while in the airNo rail grinding sound is played when Minecarts are flying through the airAdded a new accessibility setting that makes players follow the rotation of Minecarts they rideDefaults to offOnly has effect when within a world with the experiment enabledAdded new gamerule minecartMaxSpeed that changes the maximum speed of MinecartsDefaults to 8 and goes up to 1000 blocks per second.Setting it to a specific value does not guarantee that a minecart will reach that particular max speed - there are built in air resistances and similar effects that the speed added through slopes or powered rails need to overcomeThis gamerule only exists in worlds with the experiment enabledMinecart ChangesMinecarts can no longer be placed within another Minecart by the playerDispensers can still "stack" Minecarts by placing them on the Rail, even if there is another Minecart already thereMinecarts can now consistently be placed next to each other along a trackMinecarts now pick up mobs more consistently when moving along a trackMinecarts will no longer phase through blocks on slopesKnown ImpactWe are aware that these changes will affect certain contraptions such as 'piston bolts', which may now not work at all, or have their behavior changedVery delicate rail networks will have their timings changed due to slight changes in speeds, movement distance, friction etc.Contraptions that rely on Minecarts snapping to rails will no longer work, or have their behavior changedOther than these, there are several technical changes and features in Minecraft 1.21.2 update. Interested players can check the full patch notes on the official Minecraft website.
