 * : A boolean [default: ] specifying whether to include the world seed when seeding the sequence.
 * means the sequence will evaluate to the same regardless of which world the command is run in.
 * : A boolean [default: ] specifying whether to include the sequence ID when seeding the sequence.
 * means all sequences will evaluate to the same regardless of which name they have.
 * By default, all sequences are seeded as,  ,  . Using   instead of a sequence ID resets all sequences and sets the default parameters.

Non-mob entities

 * Display entities
 * Display entities now start updating their client-side position and rotation on the first tick after an update.
 * In previous versions, updates were applied in the same tick, causing uneven motion.
 * New behavior is now similar to armor stands, mobs and players.
 * On the server, position and rotation are still updated immediately.
 * Duration of this interpolation is controlled by the field.
 * means that updates are applied immediately.
 * means that the display entity will move from current position to the updated one over one tick.
 * Higher values spread the movement over multiple ticks.
 * Please note that this value is clamped to avoid glitches due to periodic position updates.
 * The new value will apply only to position and rotation changes made after it changed.
 * That means any current movement will continue unchanged.
 * Note: behavior while riding remains unchanged from previous versions.

World generation

 * Ore distribution
 * Diamond ore is now generated more frequently in the deepslate layers of the Overworld.

 * More data may be present in the compound and if so is ignored.
 * Calling a non-macro function with a data compound is silently ignored.
 * When a macro is called, the values provided are substituted in place of the variable specifications and the resulting commands are executed.
 * Any syntax errors in the lines resulting from variable substitution result in the entire function call being skipped.
 * Any syntax errors in the lines resulting from variable substitution result in the entire function call being skipped.

 * New features have been added to datapacks and resource packs to allow creation of packs that are compatible with multiple versions of the game.

 * Examples:,  ,
 * field is still required and its format remains unchanged, to allow older game versions to read pack data.
 * If  is present, it must contain the value declared in
 * Since this new information is ignored by older versions of the game, they will always see a "normal", single-version pack, without any extended compatibility.
 * Packs can now contain overlay directories ("overlays").
 * Overlays are sub-packs applied over the "normal" contents of a pack.
 * These directories have the same layout as the top-level pack, including the  and   directories.
 * Overlays can be applied if they support the client's pack format.
 * Overlays can add and replace files, but not remove them.
 * For example, if the overlay  is applied, the file   will replace contents of assets/minecraft/textures/bar.png
 * and  are ignored in overlay directories
 * New section called  have been added to pack metadata.

 * Every overlay entry has two fields:
 * - range of supported formats
 * - overlay directory (allowed characters: a-z, 0-9, _ and -)

 * The command and chat history can be accessed by pressing or  in the chat.
 * Regular chat is only persisted within the same game session (leaving a server or world clears them).
 * Recent commands are stored in  in the game folder.
 * Optimized the way chunks are sent to clients to allow players with low-bandwidth internet connections to play on multiplayer servers.
 * Chunks are no longer sent over the network to the client in one big continuous batch.
 * They are instead sent in smaller batches depending on the available bandwidth. This means that:
 * Clients with extremely low-bandwidth connections will not time out while loading the world.
 * Clients with low-bandwidth connections can interact with the world while some chunks are still loading.
 * Only chunks within the client's render distance are now sent.
 * Changed network protocol to allow for more data-driven content in the future.
 * Configuration phase automatically starts after login phase (i.e. after client account has been verified) and lasts until the player joins the world (play phase).
 * Clients can stay in configuration phase indefinitely - it's up to server to release it to the world.
 * Servers can also request clients to re-enter the configuration phase after it has entered the play phase.
 * Other players will see such clients as disconnected.
 * Users in configuration phase will not be visible on the player list.
 * Actions allowed in configuration phase (moved from play phase).
 * Configuration of data-driven registries.
 * Configuration of enabled features.
 * Actions shared between configuration and play phases:
 * Application of server resource packs.
 * Update of tags.
 * Exchange of custom packets.
 * Ping and keep-alive packets.
 * The server will now negotiate resource pack in the configuration phase.
 * This means that the player will no longer be in world when answering prompts and reloading resources.
 * Added validation for symbolic links in datapacks and resource packs, to improve safety.
 * This feature expands on symbolic link validation in worlds added in the previous release.
 * The game will now warn users if a pack added via drag and drop contains disallowed symbolic links.
 * Packs containing disallowed symbolic links will not be visible in UI and commands.
 * Additionally, directories and files that are not recognized as packs will no longer be copied via drag and drop.
 * When hitboxes are displayed through, entities that have a passenger will display the passenger's attachment point.

Experimental changes
These changes are accessible by enabling the "Villager Trade Rebalance" experimental toggle.

Gameplay

 * Trading
 * Changed the trading mechanism of librarians selling enchanted books.
 * Instead of offering every possible enchanted book, librarians will now be offering specific enchanted books depending on which biome they come from.
 * Jungle and swamp villages do not generate naturally. Thus, players must breed villagers or cure zombie villagers in these biomes to access their trades.
 * All tradable enchanted books now split to special books and normal books.
 * Special books have a specific enchantment with a fixed level, and are only available from master librarians with full XP.
 * Normal books have a specific enchantment without a fixed level, just like before.
 * All enchantments used for crossbow, fishing rod, and trident are removed from trading.
