Check below the changelog for other versions

What's new in carpet 1.4.22

• confirmed support for 1.16.5 (previous 1.16.4 versions should work on 1.16.5 anyways - pretty much nothing changed). Just use 1.16.4 version for 1.16.5 pre-1
• fix crashes when fiddling with villagers with /track overlays active (blame @magneticflux- )
• information about game freezing with /tick freeze is now properly disseminated to connected carpet clients on SMP servers, making their experience similar to singleplayer (blame @altrisi)

scarpet changes

• support for reading / writing json local files (blame @altrisi)
• player based events are now correctly triggered only once for targetted player, not for all online players that did not trigger that event
• fixed incorrect handling of upper bounds for slice(), slice() can also accept now negative indices.
• added 'game_data_version' to system info
• fixed behaviour of player entity variables when player respawns, and disappears and reappears.
• player() with no args in player apps always return the player associated with that player scope instance.
• limited the ability of calling recursively of game_tick inside game_tick - calling game_tick from the world is a bad practice anyways, but wasn't causing issues on vanilla, however that causes crashes on lithium. calling game_tick from a game_tick is a bad idea anways, but since it worked on vanilla, the bahaviour is kept with the warning on other modded setups (besides carpet).
• added '__on_player_swings_hand(player, hand)` event

What's new in carpet 1.4.21

• support for 20w51a
• removed onePlayerSleeping in favour of new vanilla gamerule (1.17)
• Flipped the default values of scriptsAutoload setting and stay_loaded in app config - both are true by default. Since the addition of singleplayer app shared storage, all world scripts (located in world/scripts folder) will now load automatically like datapacks. Also all apps by default stay loaded, so adding an app is as simple as dropping them in the /scripts folder.
• scarpet apps in shared singleplayer space (config/carpet/scripts) can be organized in subfolders. App names still need to be unique
• ability to change player's selected hotbar slot with /player command
• /overlay <shape> <radius> ... <selector> can now accepts any entity selector. Shapes opacity and thiccness depends now on the number of shapes to draw per command
• fixed behaviour of tnt with optimizedTNT to match current vanilla mechanics (blame @altrisi )
• fake players will now respond to server idling settings and will show better death messages

scarpet changes

• system_info can be used to query client brand and server version
• app files in NBT format are now saved in a compressed way and read_file can read compressed nbt files as well (including saved structures)
• added list_files to retrieve app file listings
• run() now properly returns all command run information even if the owner of the command changes with execute
• entity_area now accepts an entity as a starting box, defined as the bounding box of that entity
• added absorbtion and XP api for player entities (blame @Ghoulboy78 )
• added weather API ( blame @Ghoulboy78 )
• added gamerule reader to system_info (blame @Ghoulboy78 ). Gamerules like carpet rules are read-only to discourage fiddling with them in scripts
• added item_list and item_tags to support item tag system
• entites can be selected using entity tags.
• added server_starts and server_shuts_down events
• apps can define their own command permission level with command_permission in config
• added player_trades to the events (blame @BisUmTo )
• range can now handle floating point chains, not just integers
• formatted texts from format() can now be concatenated using + operator (blame @altrisi )
• fixed set clearing block data in some situations. set can now accept properties as a map. Check the docs for details

What's new in carpet 1.4.20

• support for 20w49a
• carpet extensions using their own settings managers will now be properly synced with connected carpet clients. blame @altrisi
• apps now can be loaded from one location in SP: ~/.minecraft/config/carpet/scripts, not just worlds scripts folders, blame @altrisi
• you can now use a default carpet config for your worlds in ~/.minecraft/config/carpet/default_carpet.conf , blame @altrisi
• several built-in commands now are enabled by default only for OP player, it includes spawn, tick, draw, player and track. All other commands that are only informative and should not affect the world are left enabled by default for all players
• disabled fastRedstoneDust in the settings, since this feature had no effect for quite some time.
• fixed /banip failing with fake players on the server

scarpet changes

• rework on the event system. global events can now be handled by player scoped apps, and each player scoped app works independent from each other. Previously handling of the event was shared between all player instances of the same app, which is not the case anymore. Otherwise it should work as before, but please report issues with events if you find some.
• also, on the topic, added a bunch of optimizations to reduce memory and call stack profile - please report if weird sh..t is happening due to that. Should be fine...
• inventory_* functions can now access different inventories of the same entity via defining the access type. For instance players have default inventory, enderchest and equipment.
• inventory API allows to access equipment inventory of all living entities
• support for more vanilla argument types for custom commands: slot and blockpredicate
• added tag_matches() to detect if one tag is contained in another tag
• added support for teams via team_list, team_add, team_remove, team_leave and team_property - blame @replaceitem
• added player_escapes_sleep event, when player cancels sleep in bed using Esc key, not the cancel button. Weird, I know, but it was needed.
• block_state() can now accept a block string, returning it default or defined state
• fixed handling of invalid structures with invalid boxes. These only surface when using worlds modified with worldgen datapacks
• plop() with no arguments now returns full lists of possible features and structures to plop, including moded ones.
• added block_list() and block_tags() to handle block tags queries
• biome() with extra parameters now allow to query properties of biomes. With no parameters, returns a full list of available biomes in the world, including moded ones.
• added display_title() to put the text right in your face. blame @altrisi
• added bossbar(), blame @replaceitem

• added 'on_ground' query to entity API
• proper error reporting when operators are missing between new-style list and map constructors.
• tweaked line particle display and chunk_display app so it renders better on vanilla clients. Still better to view them on carpet clients

• fixed compatibility issues with reach entity attributes
• fixed compatibility issues with optifine. Backported to 1.4.0 for 1.16.1 as ....build2

• events of taking damage, block breaking, and using item are called a bit earlier - before they have an effect in vanilla
• fixed nbt values reporting their initial value despite being modified
• events of updating hotbar slot and craft request will trigger only once

What's new in carpet 1.4.2

• supports 20w28a
• adjusted names of structures in built-in overlay app to adjust to 1.16.2 changes

scarpet changes

• addition on maps treats them like sets and produces merged maps. Lists operations are still propritizing vector approach, not lists approach.
• new structure and plop (world gen) API for 1.16.2 (incoming) support for features and structures in json. Your previous names used with structure API and especially plop will not work but going forwards, names will be compatible with Mojang datapack specs.
• documented how to setup scarpet markers as armorstand type markers

What's new in carpet 1.4.1

• added renewableBlackstone forming when lava flows next to blue ice WITHOUT soul soil below it.

scarpet changes in 1.4.1

• Officially supported new map and list constructor syntax. You have 1.4.0 and are missing {} and [] - don't worry - it works in 1.4 as well, it is just not documented. Previous functional notation (using m() and l() ) is fully supported and the 'proper' way to do it.
• -> operator in map constructor context now returns a tuple of its arguments. To construct a set of functions, you would have to add them one by one now, as -> will be creating pairs, not defining functions

Previously:

__config() -> m( l('stay_loaded', true) );
global_precious_blocks = l('dirt', 'stone');

Now, this would also work:

__config() -> { 'stay_loaded' -> true };
global_precious_blocks = ['dirt', 'stone'];

• fixed lighting issues when resetting chunks with reset_chunk. Now it all resets properly. Thanks to PhiPro
• added persistence (query and modify) to the entity API
• without_updates and in_dimension should now be thread safe
