  • When experience is gained, the experience bar will appear
  • If there are no other players in the world, the experience bar will display as normal
• Facing other players within a 120 degree range will display those players as colored indicators on the Locator Bar
  • Other players that are above/below the screen will also display an up/down arrow, together with their indicator
  • The indicator will change to different sized icons depending on how far away the other player is
  • Colored indicators are randomized for each player
    • Operators can modify the colors of indicators with the /waypoint command
      • e.g.: /waypoint modify @s color red to set an indicator to red
    • Players on a team will override their default indicator color with their team color

Mobs

Ghastling

• The Ghastling is a young version of the Happy Ghast mob
• Spawns from a Dried Ghast block that has continuously been waterlogged for about 20 minutes
• After spawning, the Ghastling will try and follow:
  • Players within a 16-block radius or
  • An adult, non-aquatic passive mob or some of the neutral mobs within a 16-block radius
• If no player or suitable mob is close around, the Ghastling will idle around within 32 blocks from its home position where it spawned or was last interacted with
  • It will reset its home position if it is moved more than 16 blocks away from the border of its home position
• Can be tempted and fed using Snowballs
• Will grow up into a Happy Ghast after about 20 minutes, or faster if fed Snowballs

Happy Ghast

• Grows up from a Ghastling
• Can be equipped with a Harness and then be mounted by up to four players
• Tempted by Snowballs and Harness
  • The Happy Ghast can only be tempted with a harness when it has no harness equipped
• Slowly regenerates health, with regeneration speeding up during rain, snow or when flying at the same height as clouds
• The first player that mounts the Happy Ghast will control it, sitting above it in the front seat
  • When controlled, the goggles of the Happy Ghast flip down to cover its eyes
  • Press forward and back — move in the direction the player is looking
  • Press left and right — strafe in the respective direction
  • Press jump — fly directly up
  • Press sneak — dismount the Happy Ghast
• Players mounting after the first player are placed in slots on each side of it, starting clockwise from the first player
• If the Happy Ghast detects players standing on top of it, it ceases all movement and rotates to the closest cardinal direction
  • This happens regardless of whether it has a Harness equipped or not
• When mounted on the Happy Ghast, the third-person camera is further away from the player
• When there are no players mounted or walking on the Happy Ghast, it starts its roaming behavior
  • If players dismount midair, the Happy Ghast will descend towards the ground before it starts roaming
  • The roaming behavior is similar to the Ghastling, except for the radius being 64 blocks
  • When wearing a Harness, the Happy Ghast roams closer to the home position, within a 32 block radius
  • When leashed, the Happy Ghast has a roaming distance of 10 blocks
  • The Happy Ghast will try to stay close to blocks when roaming
• Cannot be bred
• Cannot enter boats

Items

Elytra

• While gliding, using a Firework Rocket will only be used as a boost even if it could be placed on a block

Lead

  • Using a Firework Rocket when flying with leashed entities will now break the leash connections
• Leashes are now rendered twice as thick, matching Minecraft: Bedrock Edition
• Leashes can now be used to leash two mobs together
  • Sneak-interact on any mob while holding leashed mobs will leash these mobs to the entity interacted with
  • Re-leashing an entity is prevented if the re-leashing would result in immediate leash snapping due to distance
• Leashes can be snipped from an entity when interacting with them using Shears
  • This applies to its own leash connection as well as all entities attached to it
  • Dispensers can now snip leashes from entities in front of them when they are equipped with Shears
• When leashing an already leashed mob, their previous leash snaps
• You cannot steal leashed entities from other players
• Interactions with a Leash knot/Fence:
  • Fails for entities that are not in range of the Leash knot/Fence
  • All entities leashed to the player will be leashed to the Leash knot/Fence
  • Transfers all its leashed entities to the player if the player has no entities leashed
  • Sneak-interact only ever attaches leashes
  • Shearing or punching the Leash knot will break all current leash connections
• A Leash knot requires at least one connection to exist
• Boats and large mobs that can be leashed but cannot fit in a boat (Horses, Donkey, Mule, Camel and Sniffer) can be leashed in a special quad connection to the Happy Ghast
  • Happy Ghast will also show a custom layer when it is leashing something using a quad connection
  • Entities leashed in quad connection are now rendered without slack
• Leash snapping distance has been changed from 10 to 12 blocks

• Recipe unlocks when a player picks up their first Leather

• Some loot tables have had saddles removed from them (see Loot table below)

Shears

  • This does not work if the mob has a rider, or if the player is crouching
  • Saddles cannot be removed from Ravagers using Shears
  • Dispensers with Shears cannot remove Saddles, Horse Armor, Harnesses or Carpets equipped on mobs
  • Shearing Saddles, Horse Armor, and Carpets will emit a vibration frequency of 6, along with the Unequip frequency of 4

Splash potions

• Splash Potions distance to affected entities now depends on the closest distance between the entity hitbox and the splash potion hitbox where it landed
  • This means that if an entity is hit directly by the splash potion, it will receive the full effect of the potion

Loot table

The following loot tables have had Saddles removed from them and replaced with 1-5 Leather:

Projectiles

• The target tolerance margin of projectiles now changes over time
  • Previously, all projectiles had a target tolerance margin of 0.3 blocks
  • Now, all projectiles start with no margin for the first two ticks of their flight
  • After that, the target margin will expand by 0.05 blocks per tick until it reaches the previous 0.3 blocks margin
  • This allows for better precision close to the shooting player or entity, while still allowing for some collision leeway when the projectile is further away

Realms

• Changed the layout of the Realms configuration screen to use tabs
• The Worlds tab allows changes to any of the world slots, creating new worlds and changing their settings

Attributes

Added camera_distance

• Default value: 4.0
• Modifies the distance at which the camera is placed away from the player or spectated entity when in a third-person view
• If the entity being ridden has a larger camera_distance attribute, that distance will be used
• This distance is multiplied by the scale attribute to get a final target camera distance

Changed flying_speed

• The flying_speed attribute now also applies to Ghasts and Happy Ghasts

Added waypoint_transmit_range and waypoint_receive_range

• Default: 0.0, Minimum: 0.0, Maximum: 60000000.0
• Players have a default transmission and reception range of 60,000,000
• Mobs with a transmission range above zero will send waypoint packets to nearby receivers that are within that range
• Similarly, receivers only receive waypoints that are inside their reception range (and receive nothing if that range is zero)
• Examples:
  • /attribute @s minecraft:waypoint_transmit_range base set 0 will prevent a player from transmitting (hiding them)
  • /attribute @s minecraft:waypoint_transmit_range base set 80 will only let a player transmit up to 80 blocks (hiding them from players further away than that)
  • /attribute @s minecraft:waypoint_receive_range base set 0 will prevent a player from receiving (turns off their Locator Bar)

    • /set <waypoint_style/resource> changes the style to a specific asset under /waypoint_style/ (see Waypoint Styles section below)
  • reset will restore the default icon behavior of the Locator Bar
• Waypoint Styles
  • These define custom icons to be displayed on the Locator Bar and are within the waypoint_style/ asset directory.
  • The default implementation is as such:

{
  "near_distance": 128,
  "far_distance": 332,
  "sprites": [
    "minecraft:default_0",
    "minecraft:default_1",
    "minecraft:default_2",
    "minecraft:default_3"
  ]
}

• • • near_distance and far_distance are optional and default to the values 128 and 332 respectively.
      • far_distance distance must be greater than near_distance

area_effect_cloud

• The Particle field has been renamed to custom_particle, and now always functions as an exact override for the default colored entity_effect particle
  • The field will not be written if no override is specified

tnt

• The entity that primed the TNT is now stored in an optional owner field (UUID of the Living entity)

vex

• The owner of a Vex is now stored in an optional owner field (UUID of the mob)

Dialogs

• Added a way to display simple modal dialogs to a user
• Dialogs are stored in a minecraft:dialog registry, but can also be defined inline
• Dialogs are an experimental feature
• To avoid user confusion, dialog screens are marked with a warning sign next to the title
  • Clicking on this warning leads to a screen that explains to the user that this screen is provided by custom content
  • It also gives the user an option to leave the current world to avoid them being locked in an infinite loop of dialogs
  • If a new dialog is received by the client while a warning screen is visible, it will not replace it, but when the user clicks the "Back" button, the new dialog will be restored instead
• Dialogs can be displayed by the server in play and configuration connection phases
  • However, only inline registries are allowed in configuration, since registries are not yet available in that phase
  • Additionally, run_command click event is not available in the configuration phase
• Dialogs by default will close after the Escape is pressed
  • When this happens, the dialog will run the action specific to the dialog type described as "exit action" below
  • This behavior is configurable
• When the dialog screen is closed, the game goes back to the previously displayed non-dialog screen or back to gameplay
  • That means that new dialogs always replace already opened ones, if any
• Dialogs can be configured to be accessible from the Pause menu
  • This replaces and expands the "Server Links" button added in previous versions
• A new key bind called "Quick Actions" has been added to allow accessing content-configured dialogs

• Most dialogs follow a common layout, however exact contents depend on type:
  • Header with title and warning button
  • Body elements, scrollable if needed:
    • messages and items
    • inputs
    • actions buttons
  • Optional footer, contains main buttons and submit actions
• Developer's Note: Dialogs are not supposed to fully describe any in-game UI, but just to allow custom content to display simple messages and get input from users. This feature is intentionally limited to match that use case.

Dialog Description Format

• Dialogs are stored in the minecraft:dialog registry that can be provided by a datapack
• Fields:
  • type: one of dialog types from the minecraft:dialog_type registry
  • <type-specific>: see below

    • none: do nothing, i.e. keep the current screen open
      • only available if pause is false to avoid locking the game in single-player mode
    • wait_for_response: replace the current dialog with a "Waiting for Response" screen
      • this option is intended to prevent users from sending multiple actions on laggy connections
        • servers are expected to eventually replace this screen with a new dialog
      • to avoid accidental locking, a "Back" button will become active after 5 seconds
        • clicking this button will continue as if the dialog was closed (i.e. the game returns to the previous non-dialog screen, if any)
      • the "Waiting for Response" screen will unpause the game in single-player mode to avoid locking the game

  • multiline: if present, allows users to input multiple lines, optional object with fields:
    • max_lines: if present, limits maximum lines, optional positive integer
    • height: height of input, optional integer from 1 to 512
      • If this field is omitted, but max_lines is present, the height will be chosen to fit the maximum number of lines (but cannot exceed 512)
      • If this and max_lines are both omitted, it will default to a height that fits 4 lines

Actions

Dialogs have at least one action, presented to the user as a button. After every action, the dialog will always evaluate contents of the after_action field (see above).

• Fields:
  • label: button label, text component
  • tooltip: optional text component to display when the button is hovered or focused
  • width: width of the button, integer from 1 to 1024 (inclusive), default: 150
  • action: action to perform when the button is clicked, optional object with fields:
    • type: value from the minecraft:dialog_action_type registry
    • <type-specific>: see below, depends on type

Static dialog action types

• All existing click_event actions (except for open_file) are included as dialog action types.
• Uses same format as click_event on text components (but with action replaced with type). For example, when using show_dialog, the entry for the action button will look like this:

{
    "label": "some label",
    "action": {
        "type": "show_dialog",
        "dialog": "some:id"
    }
}

minecraft:dynamic/run_command Action Type

• This action will build a run_command event using a provided macro template
• The macro will be expanded with string values from inputs
• For example, if the macro template is some_command $(some_input), the string value from input with key of some_input parameter will be used for the template expansion
• Inputs not used in the macro will be ignored, while macro parameters not matching any inputs will be replaced with an empty string
• Fields:
  • template: string with a macro template to be interpreted as a command

minecraft:dynamic/custom Action Type

• This method will build a minecraft:custom event using all input values
• All input contents will be sent together inside a compound tag, with the tag value of each input put under id from key field of that input
• Additional static fields can be added to the payload
• Fields:
  • additions: fields to be added to the payload, optional compound tag
  • id: namespaced ID

Built-in dialogs

The built-in datapack contains some custom dialogs to provide customization of specific screens used by the client.

minecraft:custom_options

• Shows the contents of the minecraft:pause_screen_additions tag (see below)
• Allows the user to select a specific dialog if this tag contains multiple entries
• Note: Since this tag is meant for interoperability, any content that replaces this dialog should be careful not to hide other dialog providers

minecraft:server_links

• Replacement for the previously existing "Server Links" screen
• Meant to simplify migration for servers that previously used this feature

Pause screen configuration

• A data pack can request some of the available dialogs to be accessible from the Pause screen
• This feature replaces the "Server Links" button and is placed on the Pause screen according to the same rules
• Buttons leading to dialogs exposed in this way will use the label described in the external_title field
• This feature is configured by the minecraft:pause_screen_additions dialog tag:
  • If this tag is not specified or is empty, but the server has sent the server_links packet, the tag will be handled as if it contained the minecraft:server_links dialog
    • Note: this matches previous Server Links feature behavior
    • If this dialog is removed, the tag remains empty
    • If this tag is still empty, the button will not be visible ("Send Feedback" and "Report Bugs" buttons are visible instead)
  • If this tag has a single element, the Pause screen button will lead directly to that dialog
  • If this tag has multiple elements, the Pause screen button will lead to a minecraft:custom_options dialog, which (by default) lets the user select one of the tag elements
    • If this dialog is removed, the button will not be visible

Quick Actions key bind

• A new key bind has been added that allows users to access a set of dialogs
• Default key: G
• This feature is configured by the minecraft:quick_actions dialog tag
  • If this tag is empty, the key bind will do nothing
  • If this tag has a single element, the key bind will open that dialog
  • If this tag has multiple elements, the key bind will lead to the minecraft:quick_actions dialog, which (by default) lets the user select one of the tag elements
    • If this dialog is removed, the key bind will do nothing
• This option is intended for use in custom content and by servers, so this tag is empty in the Vanilla pack

Game Rules

Added LocatorBar

• Default is true: enabling the Locator Bar
• Changing to false will remove all existing Waypoints from all players

Tags

• Block tags:
  • Added #happy_ghast_avoids: blocks that Happy Ghasts avoid getting close to
  • Added #triggers_ambient_desert_dry_vegetation_block_sounds: blocks that can trigger ambient desert dry vegetation sounds to play from blocks above
  • Added #triggers_ambient_dried_ghast_block_sounds: blocks that can trigger ambient Dried Ghast sounds to play when a Dried Ghast block is placed on them
  • Renamed #plays_ambient_desert_block_sounds to #triggers_ambient_desert_sand_block_sounds
• Item tags:
  • Added #happy_ghast_food: items that can be used to feed Happy Ghasts
  • Added #happy_ghast_tempt_items: items that can be used to tempt Happy Ghasts
• Entity tags:
  • Added #can_equip_harness: entities that can equip the Harness item
  • Added #followable_friendly_mobs: non-baby entities that will be followed by Baby Happy Ghasts (Ghastlings)

Text Components

Click Events

• Users will now be prompted for confirmation before executing a command from the run_command click action in books and chat if the command cannot be parsed or requires elevated permissions (i.e., higher than 0)

Added minecraft:custom

• When the user clicks a component with this click action, the client will send a dedicated packet minecraft:custom_click_action to a server
• The intended use is as an alternative for run_command, to be used by modded servers without worrying about having to add custom commands
• This packet has no functionality on Vanilla servers
• Fields:
  • id: namespaced ID
  • payload: optional tag field

Added minecraft:show_dialog

• When the user clicks this component, a dialog will be opened for them
• Fields:
  • dialog: namespaced ID from the minecraft:dialog registry or inline dialog value as described above

Waypoint Broadcasting

The Locator Bar works through a server-controlled Waypoint system. Waypoints are received by Players, and connections between Waypoints and Players are managed by the multiplayer server.

• By default, all Players transmit a Waypoint from themselves, and all Players receive all Waypoints
• Individual Players can have their transmission and receive ranges controlled by the waypoint_transmit_range and waypoint_receive_range attributes

Resource Pack versions 56 through 63

• The game will now consistently respect the blur texture parameter in .png.mcmeta files
• All core shader uniforms are now uniform blocks
• The cloud texture (clouds.png) can no longer be colored
• Panorama textures must now all be the same size, and square

Block Models

• elements[].rotation.angle value in block models is no longer limited to multiples of 22.5 degrees, and can now be any angle from -45 to +45

Equipment Assets

• Added new happy_ghast_body layer type, rendering in the body slot of the Happy Ghast

Font

• Unifont
  • Updated Unifont to 16.0.03
  • Added previously omitted Unifont glyphs for Private Use Areas
    • Those glyphs are loaded as a separate sub-font minecraft:include/unifont_pua and are not included in any normally used font
    • Characters in those areas are managed by Under-CSUR (Under-ConScript Unicode Registry), which adds various scripts not present in the official Unicode set, like Tengwar or Sitelen Pona

• unihex Font Provider
  • The size_overrides field is now optional, defaults to an empty list

Item Models

• Item model definitions now have a boolean field oversized_in_gui, which is false by default
  • If true, the item model will be allowed to be bigger than its item slot
  • If false, the item model will be clipped to the item slot size when being rendered in gui
  • This ability of items being rendered outside their slots should not be considered officially supported, it was temporarily restored as an exception since many servers are relying on it
  • At some point in the future, we hope to replace it with an officially supported way of achieving similar functionality
• Introduced new item model minecraft:player_head to handle player profile texture loading and rendering
• Removed support for minecraft:profile from minecraft:head

minecraft:player_head special model type

• Renders a player head
• Uses the profile from the minecraft:profile component to load a texture. Renders a default texture until the profile texture is fully loaded
• No fields

minecraft:head special model type

• No longer supports a profile from the minecraft:profile component to load a player texture
• Renders a default player texture when kind is player, and no texture override is supplied
• Fields remain unchanged

Shaders & Post-process Effects

• Custom uniforms provided to post-process shaders are now uniform blocks
• Uniform definitions inside json files are now per-block

Post-process Effect Definitions

• Entries in the targets map have been expanded to support new properties
  • New optional boolean field: persistent, default: false
    • If true, this render target will be persistent across frames
    • The contents of the target will be cleared when the screen is resized
  • New optional field: clear_color, default: [0, 0, 0, 0]
    • Format: integer ARGB value, or float array in order [R, G, B, A]
    • When this target is created or cleared, it will be filled with this color

• The uniforms value is now a list-per-block, instead of a global list
  • e.g. uniforms: { "UniformBlockName": [ { "type": "vec2", "value": [...] } ] }
    • The order of uniforms in a block must match the order in the shader

• name as part of a uniform definition is no longer used
  • We encourage setting it to help keep the json file organized/readable, but the game will not use it

• value as part of a uniform definition replaces the old values, and the type depends on the type field
  • This field is required
  • "type": "int" needs "value": 123 (a single int)
  • "type": "float" needs "value": 123.4 (a single float)
  • "type": "vec2" needs "value": [1.2, 3.4] (two floats)
  • "type": "vec3" needs "value": [1.2, 3.4, 5.6] (three floats)
  • "type": "ivec3" needs "value": [1, 2, 3] (three ints)
  • "type": "vec4" needs"value": [1.2, 3.4, 5.6, 7.8] (four floats)
  • "type": "matrix4x4" needs "value": [1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0] (four rows of four columns of floats)
• We do not validate that the uniform block is valid for a given shader, giving incorrect information will cause undefined and funky behavior

Post-process Effect Shaders

• Instead of every uniform being an individual opaque type, they are now grouped in uniform blocks
• They will be set according to the pass definition in the json file, and may be shared across both vertex and fragment shaders
• The list of sizes (all vec2 *Size uniforms) are now replaced with a single SamplerInfo uniform block
  • This contains, in order, the size of the output texture followed by the size of every input texture
  • The order of textures in the definition file will dictate the order of samplers in this uniform
  • For most post chains this is just OutSize and InSize as before
  • All sizes are vec2

post/bits.fsh

• Expects a BitsConfig of float Resolution, and float MosaicSize

post/blit.fsh

• Expects a BlitConfig of vec4 ColorModulate

post/blur.vsh and post/box_blur.fsh

• Expects a BlurConfig of vec2 BlurDir, and float Radius

post/color_convolve.fsh

• Expects a ColorConfig of vec3 RedMatrix, vec3 GreenMatrix, and vec3 BlueMatrix

post/invert.fsh

• Expects a InvertConfig of float InverseAmount

post/rotscale.vsh

• Expects a RotScaleConfig of vec2 InScale, vec2 InOffset, and float InRotation

post/spiderclip.fsh

• Expects a SpiderConfig of vec4 Scissor, and vec4 Vignette

Shader Fog Changes

• The fog is now split into environmental and render-distance-based fog
• Previously, both of those concepts were mixed in the same uniforms
• Environmental fog is supposed to represent the "fogginess" of the environment the player is in
  • e.g. lava, water, and now also atmosphere
• Render distance fog is supposed to obscure the border of visible terrain
• Environmental fog uses spherical distance to determine its intensity, render distance fog uses cylindrical distance
• The resulting fog value for any given vertex is the maximum of both

Uniform blocks

CloudInfo Uniform Block

• Only available to the clouds shaders (rendertype_clouds.vsh/rendertype_clouds.fsh)
  • Contains CloudColor, CloudOffset, and CellSize (new)
    • CellSize contains the size of an individual cloud cell

DynamicTransforms Uniform Block

• Available through #moj_import <minecraft:dynamictransforms.glsl> for convenience
• Is no longer available to shaders that do not normally use it
• Contains ModelViewMat, ColorModulator, ModelOffset, TextureMat, LineWidth
  • These are very likely to change in the near future
  • The values of some of these are often hard coded and may not make sense for a given shader, ie LineWidth in any non-line based pipeline

Fog Uniform Block

• Available through #moj_import <minecraft:fog.glsl> for convenience
• Most shaders are able to receive this uniform block, even if they do not normally use it
• Contains FogColor, FogEnvironmentalStart (new), FogEnvironmentalEnd (new), FogRenderDistanceStart (renamed from FogStart), FogRenderDistanceEnd (renamed from FogEnd), FogSkyEnd (new) and FogCloudsEnd (new)
  • FogSkyEnd is new and represents where the fog should end when drawing for the sky
  • FogCloudsEnd is new and represents where the fog should end when drawing the clouds
  • FogRenderDistanceStart is the render distance fog start
  • FogRenderDistanceEnd is the render distance fog end
  • FogEnvironmentalStart is new and represents the start of environment-based fog
  • FogEnvironmentalEnd is new and represents the end of environment-based fog
• FogShape was removed. Render distance fog is now cylindrical and environmental fog is spherical

Globals Uniform Block

• Available through #moj_import <minecraft:globals.glsl> for convenience
• Most shaders are able to receive this uniform block, even if they do not normally use it
• Contains ScreenSize, GlintAlpha, GameTime and MenuBlurRadius (new)
  • MenuBlurRadius is the blur radius of the background when a menu is open

Lighting Uniform Block

• Available through #moj_import <minecraft:light.glsl> for convenience
• Most shaders are able to receive this uniform block, even if they do not normally use it
  • The values may not make sense if the shader would not normally expect it, however
• Contains Light0_Direction and Light1_Direction

LightmapInfo Uniform Block

• Only available to the lightmap shader (lightmap.fsh)
• Contains AmbientLightFactor, SkyFactor, BlockFactor, UseBrightLightmap, NightVisionFactor, DarknessScale, DarkenWorldFactor, BrightnessFactor, SkyLightColor with no change in behavior

Projection Uniform Block

• Available through #moj_import <minecraft:projection.glsl> for convenience
• Most shaders are able to receive this uniform block, even if they do not normally use it
• Contains ProjMat with no changes

Sounds

• Changed the location of the sounds for Glow Squid, Squid, Guardian, Horse, Rabbit, and Pufferfish from the entity folder to the mob folder

UI Sprites

• The mob effect atlas has been removed, and sprites in the textures/mob_effect/ folder are now included within the GUI atlas
  • This means mob effect sprites now support GUI sprite scaling properties
• Added icon/music_notes and toast/now_playing sprites

Waypoint Styles

These define custom icons to be displayed on the Locator Bar and are within the waypoint_style/ asset directory.

• near_distance and far_distance are optional, and default to the values 128 and 332 respectively
  • far_distance distance must be greater than near_distance
• sprites is a list of at least one sprite ID within the prefix of hud/locator_bar_dot/ (the directory textures/gui/sprites/hud/locator_bar_dot)
• An example "bowtie" waypoint style is provided and accessible via the command:
  • /waypoint modify <entity-selector> style set bowtie
• When the distance to the waypoint is less than near_distance, the first sprite in the list will be selected
• When the distance to the waypoint is greater than far_distance, the last sprite in the list will be selected
• Between this range, sprites will be selected based on the linear progress between the near and far distances

Fixes

• The fix to MC-3697 has been partially reverted.
  • Decorative hanging entities such as paintings and item frames are now immune to explosions from submerged TNT while items and armor stands are once again vulnerable to them
