Release 5.1.2

fixes #5810

probably fixes #4986

#5810 was caused by the workaround for #4394, which broke in 1.20 for reasons I'm still unclear on.

As FLAG_TELEPORT does not work at all for non-player entities, and causes bugs with player entities, sending the teleport movement without the flag is the least buggy way to solve all of these issues. Having the client interpolate teleport movements is not ideal, but there doesn't seem to be a way to reliably prevent it without causing even more bugs, so this will have to do.

changelogs/4.19.md

@@ -94,3 +94,18 @@ Released 14th April 2023.
 - Fixed player timings duplication leading to extremely large timings reports when timings runs for a long time with many players.
 - Packet timings are now indexed by class FQN instead of packet ID. This prevents erroneous timer reuse on packet ID reuse (e.g. multi version servers).
 - Fixed entity timings being shared by different classes with the same short name. This led to incorrect timings being reported for some entities when custom entities were used.
+
+# 4.19.3
+Released 21st April 2023.
+
+## General
+- Error IDs for `Packet processing error` disconnects are now split into 4-character chunks to make them easier to type (since they can't be copied from the disconnection screen of a client).
+
+## Fixes
+- Fixed entity-block intersections being checked twice per tick. Besides wasting CPU time, this may have caused unexpected behaviour during entity-block interactions with blocks like water or cacti.
+- Fixed performance issue in network inventory synchronization due item NBT being prepared twice.
+- Fixed `tools/simulate-chunk-selector.php` argument parsing being completely broken (weird behaviour of PHP `getopt()`).
+
+## Internals
+- `TimingsHandler->stopTiming()` now logs an error message if a subtimer wasn't stopped, rather than throwing an exception.
+  - Due to interactions between `try...finally` and unexpected errors, throwing exceptions made it difficult for plugin developers to debug errors in their plugins, since it obscured the original error.

+**For Minecraft: Bedrock Edition 1.19.80**
+
+### Note about API versions
+Plugins which don't touch the `pocketmine\network\mcpe` namespace are compatible with any previous 4.x.y version will also run on these releases and do not need API bumps.
+Plugin developers should **only** update their required API to this version if you need the changes in this build.
+
+**WARNING: If your plugin uses the `pocketmine\network\mcpe` namespace, you're not shielded by API change constraints.**
+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+### Interim releases
+If you're upgrading from 4.17.x directly to 4.20.x, please also read the following changelogs, as the interim releases contain important changes:
+
+- [4.18.0](https://github.com/pmmp/PocketMine-MP/blob/4.20.0/changelogs/4.18.md#4180) - major performance improvements, internal network changes, minor API additions
+- [4.19.0](https://github.com/pmmp/PocketMine-MP/blob/4.20.0/changelogs/4.19.md#4190) - minor performance improvements, improved timings system, minor API additions
+
+# 4.20.0
+Released 26th April 2023.
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.19.80.
+- Removed support for older versions.
+
+## Fixes
+- Fixed packet processing error when attempting to use a stonecutter.
+- Fixed armor slots containing ghost items when cancelling right-click to equip armor.
+- Fixed crash in `HandlerList->getListenersByPriority()` when no listeners are registered at the given priority.
+
+## API
+### `pocketmine\block`
+- The following API methods have been added:
+  - `public BaseSign->getEditorEntityRuntimeId() : int` - returns the entity runtime ID of the player currently editing this sign, or `null` if none
+  - `public BaseSign->setEditorEntityRuntimeId(?int $editorEntityRuntimeId) : $this` - sets the entity runtime ID of the player currently editing this sign
+
+### `pocketmine\player`
+- The following API methods have been added:
+  - `public Player->openSignEditor(Vector3 $position) : void` - opens the client-side sign editor GUI for the given position
+
+# 4.20.1
+Released 27th April 2023.
+
+## Fixes
+- Fixed server crash when firing a bow while holding arrows in the offhand slot.
+
+## Internals
+- `ItemStackContainerIdTranslator::translate()` now requires an additional `int $slotId` parameter and returns `array{int, int}` (translated window ID, translated slot ID) to be used with `InventoryManager->locateWindowAndSlot()`.
+- `InventoryManager->locateWindowAndSlot()` now checks if the translated slot actually exists in the requested inventory, and returns `null` if not. Previously, it would return potentially invalid slot IDs without checking them, potentially leading to crashes.
+
+# 4.20.2
+Released 4th May 2023.
+
+## Fixes
+- Fixed all types of wooden logs appearing as oak in the inventory.
+- Fixed a performance issue in `BaseInventory->canAddItem()` (missing `continue` causing useless logic to run).
+
+# 4.20.3
+Released 6th May 2023.
+
+## Improvements
+- Reduced memory usage of `RuntimeBlockMapping` from 25 MB to 9 MB. Since every thread has its own copy of the block map, this saves a substantial amount of memory.
+
+## Fixes
+- Fixed players falling through blocks in spectator mode.
+- Fixed timings reports getting bloated by prolific usage of `PluginManager->registerEvent()`.
+  - This was caused by creating a new timings handler for each call, regardless of whether a timer already existed for the given event and callback.
+- Fixed `Full Server Tick` and other records being missing from timings reports.
+  - This was caused by timings handler depth not getting reset when timings was disabled and later re-enabled.
+
+# 4.20.4
+Released 6th May 2023.
+
+## Fixes
+- Fixed players being forced into flight mode in every game mode.
+  - Moral of the story: do not assume anything in Mojang internals does what its name suggests...
+
+# 4.20.5
+Released 30th May 2023.
+
+## Fixes
+- Fixed server crash due to a bug in upstream dependency [`netresearch/jsonmapper`](https://github.com/cweiske/JsonMapper).

+### Note about API versions

+will also run on these releases and do not need API bumps.
+Plugin developers should **only** update their required API to this version if you need the changes in this build.

+
+# 4.21.0
+Released 17th May 2023.
+
+## General
+- PHP 8.1 is now required. Most plugins should run without changes, but some might need to be updated due to language-level deprecations.
+- Ticking chunk count is now shown separately from loaded chunk count in the `/status` command, providing useful performance information.
+- Further improved performance of ticking chunk selection.
+- Improved performance of some inventory functions.
+- Reduced server memory footprint in most cases by ~9 MB per thread.
+- Due to large overhead, async network compression is now only used for packets larger than 10 KB by default.
+
+## Configuration
+- Added the following new `pocketmine.yml` configuration options:
+  - `network.async-compression-threshold` - minimum size of packet which will be compressed using `AsyncTask`
+    - Default is 10 KB, which means that very few packets will use async compression in practice. This is because the overhead of compressing async is currently so high that it's not worth it for smaller packets.
+
+## Timings
+- Timings reports no longer include the unused metadata fields `Entities` and `LivingEntities`.
+- Timings reports now correctly calculate the peak time of a timer.
+  - Previously it was incorrectly recorded as the longest time spent in a single tick, rather than the longest time spent in a single activation.
+  - Timings report version has been bumped to `2` to reflect this change.
+- All world-specific timers now have generic aggregate timings, making it much easier to locate performance patterns across all worlds.
+
+## Gameplay
+- Players in spectator mode are no longer able to pick blocks, and now have finite resources similar to survival mode.
+
+## API
+### `pocketmine\world`
+- The following API methods have been added:
+  - `public World->getTickingChunks() : list<int>` - returns a list of chunk position hashes (a la `World::chunkHash()`) which are currently valid for random ticking
+
+### `pocketmine\inventory`
+- The following API methods have been added:
+  - `protected BaseInventory->getMatchingItemCount(int $slot, Item $test, bool $checkDamage, bool $checkTags) : int` - returns the number of items in the given stack if the content of the slot matches the test item, or zero otherwise
+    - This should be overridden if directly extending `BaseInventory` to provide a performance-optimised version. A slow default implementation is provided, but it will be removed in the future.
+  
+## Internals
+### Entity
+- Unused `NameTag` tag is no longer saved for `Human` entities.
+
+### Inventory
+- `BaseInventory` now uses a new internal method `getMatchingItemCount()` to locate items in the inventory without useless cloning. This improves performance of various API methods, such as `addItem()`, `contains()`, and more.
+- Specialization of `Inventory->isSlotEmpty()` in `BaseInventory` subclasses has been added to improve performance of some API methods.
+
+### Network
+- `RuntimeBlockMapping` no longer keeps all block palette NBT data in memory.
+  - This significantly reduces server idle memory footprint.
+  - For multi-version implementations, this will have a significant impact on memory usage, since a different block palette is often required to support each version.
+  - NBT will be lazy-loaded into memory and cached if `getBedrockKnownStates()` is called. However, this is not used by PocketMine-MP under normal circumstances.
+- Removed unnecessary usage of `Utils::validateCallableSignature()` from some internal network pathways, improving performance.
+
+### Scheduler
+- `AsyncPool` no longer double-checks progress updates on completed tasks.
+
+### World
+- Ticking chunks are now tracked in `World->validTickingChunks` and `World->recheckTickingChunks`.
+    - This allows avoiding rechecking every ticking chunk for validity during ticking chunk selection, improving performance.
+    - In some cases, this allows bypassing chunk selection entirely, reducing selection cost to zero.
+- Registered but ineligible ticking chunks are no longer rechecked every tick.
+    - This was causing wasted cycles during async worker backlog.
+    - The internal system must call `markTickingChunkForRecheck()` whenever a ticking chunk's eligibility for ticking has potentially changed, rather than just when it has changed from a yes to a no.
+
+# 4.21.1
+Released 30th May 2023.
+
+## Fixes
+- Fixed server crash due to a bug in upstream dependency [`netresearch/jsonmapper`](https://github.com/cweiske/JsonMapper).

+# 4.22.0
+Released 7th June 2023.
+
+**For Minecraft: Bedrock Edition 1.20.0**
+
+This is a support release for Minecraft: Bedrock Edition 1.20.0.
+
+**Plugin compatibility:** Plugins for previous 4.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe` namespace.
+Do not update plugin minimum API versions unless you need new features added in this release.
+
+**WARNING: If your plugin uses the `pocketmine\network\mcpe` namespace, you're not shielded by API change constraints.**
+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+## Interim releases
+If you're upgrading from 4.20.x directly to 4.22.x, please also read the following changelogs, as the interim releases contain important changes:
+- [4.21.0](https://github.com/pmmp/PocketMine-MP/blob/4.22.0/changelogs/4.21.md#4210) - PHP 8.1 minimum version, minor performance improvements
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.20.0.
+- Removed support for older versions.
+
+## Fixes
+- Removed deprecated `ReflectionProperty::setAccessible()` calls.
+- Fixed jukebox music not stopping when destroyed by an explosion.
+
+# 4.22.1
+Released 9th June 2023.
+
+## Fixes
+- Reokaced workaround for an old teleporting client bug:
+  - This workaround broke due to an additional client bug introduced by 1.20, causing players to become frozen to observers when teleported.
+  - The original client bug has still not been fixed, meaning a new workaround was needed, but no perfect solution could be found.
+  - The new workaround involves broadcasting teleport movements as regular movements, which causes unwanted interpolation between the old and new positions, but otherwise works correctly. This solution is not ideal, but it is the best we can do for now.
+  - See issues [#4394](https://github.com/pmmp/PocketMine-MP/issues/4394) and [#5810](https://github.com/pmmp/PocketMine-MP/issues/5810) for more details.

+**For Minecraft: Bedrock Edition 1.19.62**
+
+5.0.0 is a major update to PocketMine-MP, including many new features and API changes. It is **not** compatible with plugins written for previous versions of PocketMine-MP.
+
+**During the beta phase, no new features will be added.**
+
+This stage of development is focused on stability and cleaning up any major issues introduced during the alpha stage.
+
+## WARNING
+**This is a BETA release.** This means that it may be unstable, and is not yet ready for production use.
+
+Since this version has undergone substantial changes compared to 4.x, plugins written for 4.x will need to be updated to work on this version.

+  - Now generates better errors when inconsistent blockstate versions are encountered.
+  - Now generates more stable outputs when re-run on the same input.
+  - Output now uses `copiedState` in `remappedStates` where possible. This significantly reduces the size of the output for blocks with partially flattened states.
+
+## Gameplay
+- The following blocks have been added:
+  - Cave Vines
+- The following items have been added:

+- The following API methods have signature changes:
+  - `Sapling::__construct()` now accepts `SaplingType $saplingType` instead of `TreeType $treeType`
+  - `RuntimeBlockStateRegistry->register()` no longer accepts an `$override` parameter.
+- The following classes have been added:
+  - `utils\SaplingType` - enum of all sapling types
+- `utils\TreeType` has been moved to `pocketmine\world\generator\object` namespace.
+
+### `pocketmine\data\bedrock\item\upgrade`
+- The following API methods have been added:

+  - `public ItemIdMetaUpgradeSchema->getRenamedIds() : array<string, string>` - returns a map of old ID -> new ID
+  - `public ItemIdMetaUpgradeSchema->getRemappedMetas() : array<string, array<int, string>>` - returns a map of old ID -> list of old meta -> new ID
+
+### `pocketmine\event\block`
+- The following API methods have been added:
+  - `public BlockGrowEvent->getPlayer() : ?Player` - returns the player that triggered the block growth, or `null` if it was not triggered by a player

+- The following classes have been added:
+  - `WorldDisplayNameChangeEvent` - called when a world's display name is changed
+
+### `pocketmine\item`
+- `Boat` now uses a new `BoatType` enum instead of `TreeType`. This is because not all tree types have an associated boat type, and some boat types are not made from tree materials (e.g. bamboo raft).
+  - The following API methods have been removed:
+    - `Boat->getWoodType()`
+  - The following API methods have been added:
+    - `public Boat->getType() : BoatType`

+  - The following classes have been added:
+    - `BoatType` - enum of all boat types
+  - The following API methods have signature changes:
+    - `BoatType::__construct()` now accepts `BoatType $boatType` instead of `TreeType $woodType`.
+
+### `pocketmine\world`
+- The following API methods have been added:
+  - `public World->setDisplayName(string $name) : void`
+
+### `pocketmine\world\format`
+- Fixed outdated documentation for various methods of `Chunk`.
+
+### `pocketmine\world\format\io\data`
+- The following API interface requirements have been added:
+  - `public WorldData->setDisplayName(string $value) : void`
+
+## Internals
+- Reduced global usage in world providers. In the future, we want to have blockstate deserializers etc. injected rather than being global singletons.
+- `BlockStateUpgrader` now always updates the blockstate version, even if no changes were made. PM itself doesn't require this, but it's useful for tools to know whether to upgrade the data again (e.g. in testing scenarios).
+- `BlockStateDictionary` memory usage is now reduced from 9 MB to 3.5 MB using various techniques, including string reuse and binary-encoded states.
+- `RuntimeBlockMapping` has been renamed to `BlockTranslator`.
+- Singletons in the `pocketmine\network\mcpe\convert` package have been centralized under `TypeConverter`. In the future, this will be injected where needed, allowing different converters to be used for different sessions (useful for multiversion).
+- Overriding of serializers and deserializers of items and blocks is now consistently disallowed. Due to the lack of a good reason to allow overriding built-in blocks and items, this is no longer allowed.
+
+# 5.0.0-BETA4
+Released 23rd May 2023.
+
+## General
+- [`ext-pmmpthread` version 6.0.0](https://github.com/pmmp/ext-pmmpthread/releases/6.0.0) (renamed from `ext-pthreads`) is now required. This version has API changes compared to pthreads v5. Please read the linked changelog for details.
+- [`pocketmine/snooze` version 0.5.0](https://github.com/pmmp/Snooze/releases/0.5.0) is now required.
+- `pocketmine/classloader` and `pocketmine/log-pthreads` packages have been removed. The relevant classes from these packages are now included in-house in the `pocketmine/thread` namespace.
+  - `BaseClassLoader` is replaced with `pocketmine\thread\ThreadSafeClassLoader`
+  - `ThreadedLogger` is replaced by `pocketmine\thread\ThreadSafeLogger`
+  - `AttachableThreadedLogger` is replaced by `pocketmine\thread\AttachableThreadSafeLogger`
+  - `ThreadedLoggerAttachment` is replaced by `pocketmine\thread\ThreadSafeLoggerAttachment`
+
+## Fixes
+- Fixed crash on unknown blocks due to late initialization of properties in `UnknownBlock`.
+
+## API changes
+### `pocketmine\scheduler`
+- `AsyncTask->setResult()` now works with thread-safe objects. This was previously not possible due to limitations in the `pthreads` extension.

+# 5.0.0
+Released 1st June 2023.
+
+**For Minecraft: Bedrock Edition 1.19.80**
+
+5.0.0 is a major feature update to PocketMine-MP, including support for Bedrock worlds from 1.13 onwards, a large array of new blocks and items, and various changes to the plugin API.
+
+It is **not** compatible with plugins written for 4.x.y, and plugins may require code changes to work with it.
+
+**As this changelog is quite large, its accuracy and completeness cannot be guaranteed.**
+Make sure you're looking at the [latest revision](https://github.com/pmmp/PocketMine-MP/blob/stable/changelogs/5.0.md), as it may be amended after release.
+
+## Core
+- Worlds are now saved according to the Bedrock 1.19.80 format.
+- Worlds generated by Bedrock from 1.13.0 and up are now supported (previously, only worlds up to 1.12 were supported).
+- `/particle` now accepts strings for particle data instead of integers.
+- `/particle` no longer accepts integers for block or item IDs.
+- The usage of `blockcrack`, `iconcrack` and `blockdust` particle types in `/particle` now follows the same pattern as
+  other particle types, with the data for each being passed in the `data` parameter instead of being baked into the
+  particle name.
+- Commands are now enabled by default in worlds exported from PocketMine-MP to Bedrock.
+
+## Build system
+- `build/generate-block-serializer-consts.php` has been added to generate `BlockTypeNames`, `BlockStateNames` and `BlockStateStringValues` in the `pocketmine\data\bedrock\block` package.
+- `build/generate-item-type-names.php` has been added to generate `ItemTypeNames` in the `pocketmine\data\bedrock\item` package.
+- `build/generate-runtime-enum-serializers.php` has been added to generate `RuntimeEnumSerializer`, `RuntimeEnumSerializerTrait`, and `RuntimeEnumSizeCalculatorTrait` in `pocketmine\data\runtime` package.
+
+## Localization
+- Localized disconnect messages are now used in the following cases:
+  - Server full
+  - Player not on the server whitelist
+  - Player on the server ban list
+  - Invalid skin
+  - Invalid username
+  - Kicked using `/kick`
+  - Banned using `/ban`
+  - Failure to find a safe spawn position
+- Session open, session close and session player name discovery messages are now localized.
+- All permissions now have localized descriptions. These are not currently used by PocketMine-MP, but may be useful for plugins.
+
+## Performance
+- Improved performance of dropping block inventory contents when the block is destroyed.
+- Improved light propagation performance by 10-15%.
+- [`ext-pmmpthread` version 6.0.0](https://github.com/pmmp/ext-pmmpthread/releases/tag/6.0.0) is now used, featuring significant performance improvements for thread-safe objects and various threading use-cases.
+
+## Tools
+- The following tool scripts have been added:
+  - `generate-block-palette-spec.php` - generates a JSON file with a readable overview of blocks, their state
+    properties, and their possible values
+  - `generate-blockstate-upgrade-schema.php` - generates JSON blockstate upgrade schemas like those found
+    in [BedrockBlockUpgradeSchema](https://github.com/pmmp/BedrockBlockUpgradeSchema)
+  - `generate-item-upgrade-schema.php` - generates JSON item ID/meta upgrade schemas like those found
+    in [BedrockItemUpgradeSchema](https://github.com/pmmp/BedrockItemUpgradeSchema)
+  - `generate-bedrock-data-from-packets.php` - generates various files for [BedrockData](https://github.com/pmmp/BedrockData)
+    - This script accepts a txt file containing base64-encoded packet dumps.
+    - This script has been in use for several years, but has only now been open-sourced.
+    - It's used to generate data such as crafting recipes, creative inventory data, and various other blobs of data needed to support the current version of Minecraft: Bedrock Edition.

+
+### `pocketmine\block`
+#### Highlights
+- Blocks no longer use internal Minecraft IDs and metadata to identify themselves. All APIs associated with legacy IDs
+  and meta have been removed.
+- A new set of runtime IDs generated from `VanillaBlocks` is used to identify block types. These IDs are defined
+  in `BlockTypeIds`.
+  - These new IDs are used for runtime representation of blocks on chunks, and for type comparison purposes.
+  - Block type IDs are used at **runtime only**. **Do not store them in configs or databases**, as they are subject to
+    change without warning.
+  - Block type IDs are **specific to PocketMine-MP** and have no relation to the IDs used by Minecraft.
+  - Block type IDs cannot be negative
+  - Block type IDs must not be reused, even if overriding an already defined block
+- Block state properties (e.g. facing, colour, etc.) are now represented by PM-specific state data instead of legacy
+  metadata. The state data consists of:
+  - Block-item state properties - retained by items when the block is broken (colour, wet/dry, coral type, etc.) - handled by `Block->describeBlockItemState()`
+  - Block-only state data - discarded when the block is broken (facing direction, lit/unlit, powered/unpowered, etc.) - handled by `Block->describeBlockOnlyState()`
+- Chunks now store dynamic state ID derived from the runtime type ID and runtime (PocketMine-MP defined) state data.
+- Introduced "type tags" concept, which allows marking certain blocks as having certain behaviours.
+  - The idea for this system was borrowed from the Minecraft Java tags system.
+  - It's still in very early concept stage, but is currently used for deciding which types of blocks plants can be placed on without needing to enumerate every single ID in every class, eliminating a bunch of boilerplate code and improving consistency.
+- All `Block` descendents now accept `BlockTypeInfo` in the constructor, instead of `BlockBreakInfo`. This allows for future additions without needing to change dozens of overridden constructors.
+- `&$returnedItems` reference parameter is now used in some places such as `Block->onInteract()` to enable actions to return items to players without caring about whether they are in creative or anything else.
+  - This eliminates boilerplate code of deciding whether to set the player's held item or not, as well as automatically dropping any overflow items that don't fit into the inventory.
+  - This is currently used when filling/emptying cauldrons using buckets or glass bottles.
+- Dependency between `RuntimeBlockStateRegistry` (previously `BlockFactory`) and `VanillaBlocks` has been inverted.
+  - Now, blocks types are defined in `VanillaBlocks`
+  - `RuntimeBlockStateRegistry` automatically registers states for blocks defined in `VanillaBlocks`.
+  - Manual registration in `RuntimeBlockStateRegistry` is still required for custom blocks (see section below about registering new blocks).
+- `RuntimeBlockStateRegistry` now has only one purpose - to map internal blockstate IDs to `Block` objects when reading blocks from chunks. It should not be used by plugins unless registering new blocks.
+  - To get a block at runtime, e.g. stone, use `VanillaBlocks::STONE()`
+  - To load a block from **old** config or database data:
+    1. Use `GlobalBlockStateHandlers::getUpgrader()->upgradeIntIdMeta()` to convert it to modern data
+    2. Pass the data to `GlobalBlockStateHandlers::getDeserializer()` to get a blockstate ID
+    3. Pass the blockstate ID to `RuntimeBlockStateRegistry::fromStateId()` to get a `Block` instance
+  - Prefer using `StringToItemParser` wherever possible for configs and databases (see `lookupAliases()` and `lookupBlockAliases()`).
+
+#### Registering new blocks
+##### In a plugin
+To add a vanilla block in a plugin which isn't yet supported by PocketMine-MP, do the following:
+
+1. Get a new type ID using `BlockTypeIds::newId()` - _you'll want to keep this in a property somewhere if you want to
+   compare using `getTypeId()` later_
+2. Set up the block type somewhere - _this can be anywhere you like, e.g. a plugin main class property, but using
+   a `RegistryTrait` class is recommended - you'll need this later to create new instances of the block_
+3. Register the block in `RuntimeBlockStateRegistry` - _this informs the server of all the block's possible states so
+   that it can be read from chunks at runtime_
+4. Register a deserializer for the block's Minecraft ID in `BlockStateToObjectDeserializer` - _needed for the block to
+   be recognized when loaded from disk_
+5. Register a serializer for the block in `BlockObjectToStateSerializer` - _needed for the block to be saved to disk,
+   and to be sent over the network_
+6. Optionally, register a string alias for the block in `StringToItemParser` - _so that it can be given via `/give`_
+
+To see a demo of how to do this in a plugin, see [this example plugin](https://github.com/pmmp/RegisterBlocksDemoPM5).
+
+Registering custom blocks follows a similar process, but requires additional steps to modify `BlockStateDictionary`
+which won't be covered here.
+Since this is not currently officially supported by PocketMine-MP, this won't be covered here.
+
+This is admittedly rather more of a hassle than in PM4, but this system offers significantly more flexibility than the
+old system.
+
+##### As a PocketMine-MP core contribution
+To register a new vanilla block into the core, the process is slightly different:
+
+1. Instead of using `BlockTypeIds::newId()`, add a new constant for the block to `BlockTypeIds`
+2. Register the new block in `VanillaBlocks` - `RuntimeBlockStateRegistry` will automagically take notice of all blocks
+   defined in `VanillaBlocks`
+3. Follow steps 4 onwards above

+
+### `pocketmine\command`
+- Command permissions are now always checked by the server when running a command.
+  - This only affects commands implemented by extending `Command`. Plugins using `PluginBase->onCommand()` are not affected by this change, since they already had permissions checked by the server anyway.
+  - Previously, direct inheritors of `Command` were responsible for checking permissions, which required developers to duplicate the same code in every command, and opened lots of potential for security vulnerabilities.
+  - If you want to do something on permission denied (e.g. sending a special message, or audit logging), you can do so by overriding `Command->testPermission()`, instead of baking the code directly into `Command->execute()`.
+  - If you don't want to use permissions at all, just create a permission with a default of `true` (or belonging to `pocketmine.group.user`) and assign that.
+- `SimpleCommandMap` now requires all commands to have a permission set when registered.
+  - If you actually want to allow everyone to use your command (not advised), you can add a new permission to the `pocketmine.group.user` group, or use `default: true` for `plugin.yml` permissions.
+- The following API methods have changed behaviour:
+  - `Command->testPermissionSilent()` now returns `false` if there are no permissions associated with the command. This is to prevent commands with no permissions being usable by everyone, which has previously been a source of security issues.
+- The following API methods have been added:
+  - `public Command->getPermissions() : list<string>` - returns a list of permissions which grant usage access to this command. A user with one or more of these permissions will be able to invoke the command's `execute()` method
+  - `public Command->setPermissions(list<string> $permissions) : void` - sets the permissions which grant usage access to this command. This should be used instead of `setPermission()` with `;` separators (which is now deprecated)

+### `pocketmine\event`
+- The following classes have inheritance changes:

+  - `PlayerPreLoginEvent` no longer implements `Cancellable`. This caused unexpected behaviour for most plugin devs due to default-ignoring cancelled events, forcing people to usually have to use `@handleCancelled` to handle the event when they wanted to use it.
+- The following API constants have been renamed:
+  - `PlayerPreLoginEvent::KICK_REASON_BANNED` -> `PlayerPreLoginEvent::KICK_FLAG_BANNED`
+  - `PlayerPreLoginEvent::KICK_REASON_PLUGIN` -> `PlayerPreLoginEvent::KICK_FLAG_PLUGIN`
+  - `PlayerPreLoginEvent::KICK_REASON_PRIORITY` -> `PlayerPreLoginEvent::KICK_FLAG_PRIORITY`
+  - `PlayerPreLoginEvent::KICK_REASON_SERVER_FULL` -> `PlayerPreLoginEvent::KICK_FLAG_SERVER_FULL`

+  - `PlayerPreLoginEvent->clearKickReason()` -> `PlayerPreLoginEvent->clearKickFlag()`
+  - `PlayerPreLoginEvent->getFinalKickMessage()` -> `PlayerPreLoginEvent->getFinalDisconnectReason()` (now used for logs only, if a disconnect screen message is set for the highest priority flag)
+  - `PlayerPreLoginEvent->getKickMessage()` -> `PlayerPreLoginEvent->getDisconnectReason()` (now used for logs only, if a disconnect screen message is set for the flag)
+  - `PlayerPreLoginEvent->getKickReasons()` -> `PlayerPreLoginEvent->getKickFlags()`

+
+### `pocketmine\item`
+#### Highlights
+- `ItemFactory` has been removed. Vanilla item registration is now done via `VanillaItems`.
+  - To get an item at runtime, e.g. iron ingot, use `VanillaItems::IRON_INGOT()`
+  - To get a block as an item, e.g. stone, use `VanillaBlocks::STONE()->asItem()`
+  - To load an item from legacy ID and meta:
+    1. Use `GlobalItemDataHandlers::getUpgrader()->upgradeItemTypeDataInt()` to convert the legacy ID and meta to `SavedItemStackData`
+    2. Pass the itemstack data to `GlobalItemDataHandlers::getDeserializer()` to get an `Item` instance
+- Items no longer use internal Minecraft string IDs and metadata to identify themselves. All APIs associated with legacy
+  IDs and/or meta have been removed.
+- A new set of runtime item IDs generated from `VanillaItems` is now used to identify item types. These IDs are defined
+  in `ItemTypeIds`.
+  - These new IDs are primarily intended for type comparison purposes.
+  - Item type IDs are used at **runtime only**. They should **NOT** be stored in configs or databases, as they are not
+    guaranteed to remain the same between versions.
+- In some cases, items may have additional "type data" which provides extra type information about an item. This
+  replaces item metadata in some cases.
+  - Type data may be used to store dynamic type information such as dye colour, potion type, etc.
+  - Items must have the same type ID **and** type data in order to be stackable.
+- Blocks, when represented as items:
+  - retain their block type data, but not state data (for example, different colours of concrete don't stack, but things
+    like facing don't affect stackability)
+  - use the negative of their block type ID (e.g. a block with type ID `1` will have an item type ID of `-1`).
+- Durable items (e.g. tools, armour) now use NBT `Damage` tag to store durability (like Minecraft 1.13+), instead of
+  legacy meta values.
+- `&$returnedItems` reference parameter is now used in some places (e.g. `onInteractBlock()`) to enable actions to return items to players without caring about whether they are in creative or anything else.
+  - This eliminates boilerplate code of deciding whether to set the player's held item or not, as well as automatically dropping any overflow items that don't fit into the inventory.
+  - This is used for things like filling/emptying buckets and bottles, and equipping armor.
+- Blocks which previously had separate items, such as mob heads and beds, no longer do. Their item form can be acquired using `Block->asItem()` in the same way as every other block. This is facilitated by the new serializer system.
+
+#### Implementing new items
+##### In a plugin
+This follows a similar process to registering blocks.
+
+1. Get a new type ID using `ItemTypeIds::newId()` - _you'll want to keep this in a property somewhere if you want to
+   compare using `getTypeId()` later_
+2. Set up the item type somewhere - _this can be anywhere you like, e.g. a plugin main class property, but using
+   a `RegistryTrait` class is recommended - you'll need this later to create new instances of the item_
+3. Register a deserializer in `ItemDeserializer` - _needed for the item to be recognized when loaded from disk_
+4. Register a serializer in `ItemSerializer` - _needed for the item to be saved to disk, and to be sent over the
+   network_
+5. Optionally, register a string alias for the item in `StringToItemParser` - _so that it can be given via `/give`_
+
+To see a demo of how to do this in a plugin, see [this example plugin](https://github.com/pmmp/RegisterBlocksDemoPM5).
+
+Again, it's acknowledged this is rather more cumbersome than it should be, but this is an ongoing process.
+
+##### As a PocketMine-MP core contribution
+
+To register a new vanilla item into the core, the process is slightly different:
+
+1. Instead of using `ItemTypeIds::newId()`, add a new constant for the block to `ItemTypeIds`
+2. Register the new item in `VanillaItems`
+3. Follow steps 3 onwards from the plugin instructions above
+
+#### Change list
+- `Item` is no longer `json_encode()`-able.
+  - The original purpose of this was to allow items to be serialized to JSON for crafting data generated from `CraftingDataPacket`. Due to changes in the generation methodology, bypassing `Item`s entirely, this is no longer necessary.
+  - In addition, `jsonSerialize()` required the item to know about the method by which it will be serialized (since there is no way to inject context), creating a cyclic dependency between the `Item` implementation and its serialization method.
+  - It's relatively easy to write a replacement method to encode items to JSON as you desire.
+  - `Item::legacyJsonDeserialize()` (previously `Item::jsonDeserialize()`) is retained to allow loading legacy data, although it may be removed in the future.
+- The following classes have been removed:
+  - `Bed`
+  - `ItemFactory`
+  - `ItemIds`
+  - `Skull`
+- The following classes have been added:
+  - `BoatType` - enum of all boat types
+  - `CoralFan`
+  - `HoneyBottle`
+  - `MedicineType`
+  - `Medicine`
+  - `Spyglass`
+  - `SuspiciousStewType`
+  - `SuspiciousStew`
+- The following API methods have been added:
+  - `protected Item->describeState(RuntimeDataDescriber $w) : void` 
+  - `public Armor->clearCustomColor() : $this` - clears the custom color of an armor item
+  - `public ArmorTypeInfo->getToughness() : int`
+  - `public ArmorTypeInfo->isFireProof() : bool`
+  - `public Boat->getType() : BoatType`
+  - `public Dye->setColor(\pocketmine\block\utils\DyeColor $color) : $this`
+  - `public Item->getStateId() : int` - returns a runtime numeric state ID for comparisons including information such as coral type, dye color, etc. - DO NOT save this to disk or databases
+  - `public Item->getTypeId() : int` - returns a runtime numeric type ID for comparisons - DO NOT save this to disk or databases
+  - `public Item->isFireProof() : bool`
+  - `public ItemIdentifer->getTypeId() : int`
+  - `public Potion->setType(PotionType $type) : $this`
+  - `public SplashPotion->setType(PotionType $type) : $this`
+  - `public StringToItemParser->lookupAliases(Item $item) : list<string>` - returns a list of all registered aliases for the given item
+  - `public StringToItemParser->lookupBlockAliases(Block $block) : list<string>` - returns a list of all registered aliases for the given block
+  - `public static ItemIdentifier::fromBlock(Block $block) : self`
+- The following API methods have been removed:
+  - `Boat->getWoodType()`
+  - `Item->getId()` - for type comparisons, use `Item->getTypeId()` instead
+  - `Item->getMeta()` - use the item's specific API methods to compare information such as colour, potion type etc.
+  - `Item->hasAnyDamageValue()` - for meta wildcard recipe ingredients, use `pocketmine\crafting\MetaWildcardRecipeIngredient` instead
+  - `ItemIdentifier->getId()`
+  - `ItemIdentifier->getMeta()`
+- The following API methods have been renamed:
+  - `Item::jsonDeserialize()` -> `Item::legacyJsonDeserialize()`
+- The following API methods have signature changes:
+  - `ArmorTypeInfo->__construct()` now accepts optional parameters `int $toughness` and `bool $fireProof`
+  - `BoatType::__construct()` now accepts `BoatType $boatType` instead of `TreeType $woodType`.
+  - `Item->onAttackEntity()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onClickAir()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onDestroyBlock()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onInteractBlock()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onReleaseUsing()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `ItemIdentifier->__construct()` no longer accepts a `$variant` parameter, and now expects an item type ID for the ID parameter
+  - `LegacyStringToItemParser->addMapping()` now accepts a string for ID, instead of an integer
+- The following API methods have behaviour changes:
+  - `Item->equals()`'s `$checkDamage` parameter is now ignored, as tool damage is now stored as an NBT tag. This parameter wasn't removed due to being followed by a second `bool` parameter, which would potentially end up in the wrong place and silently cause bugs in updated plugins.
+  - `Item->equals()`'s `$checkTags` parameter will now cause tool and armor damage to be checked if true.
+- The following enums have new members:

+  - `Player->kick()` now accepts an additional `Translatable|string|null $disconnectScreenMessage` parameter, which is the message to be displayed on the disconnect screen (the message in `$reason` is used if null is passed)
+  - `Player->sendJukeboxPopup()` now accepts `Translatable|string` instead of `string, string[]`
+- The following classes have been removed:
+  - `PlayerChunkLoader` - deprecated in 4.19.0 (this was technically internal, but never marked as such)
+
+### `pocketmine\player\chat`
+- The following new classes have been added:
+  - `ChatFormatter` - interface implemented by chat formatters - this is far more powerful than the old API
+  - `LegacyRawChatFormatter` - implements the same behaviour previously used by `PlayerChatEvent->setFormat()`
+  - `StandardChatFormatter` - formats chat messages in the vanilla Minecraft style
+
+### `pocketmine\scheduler`

+  - `io\GlobalBlockStateHandlers` - gives access to block data serializer, deserializer, and upgraders
+  - `io\GlobalItemDataHandlers` - gives access to item data serializer, deserializer, and upgraders
+  - `io\LoadedChunkData` - represents a chunk loaded from disk, along with information such as whether the chunk was upgraded and what fixes it requires
+- The following new API methods have been added:
+  - `public SubChunk->getBiomeArray() : PalettedBlockArray`
+- The following classes have been removed:
+  - `BiomeArray` - `PalettedBlockArray` is now used for 3D biome data
+- The following API methods have changed signatures:
+  - `Chunk->getBiomeId()` now accepts `int $x, int $y, int $z` instead of `int $x, int $z`
+  - `Chunk->setBiomeId()` now accepts `int $x, int $y, int $z` instead of `int $x, int $z`

+- The following API methods have been removed:
+  - `NoteInstrument::fromMagicNumber()`
+  - `NoteInstrument->getMagicNumber()`
+
+## Internals
+- All external usages of `KnownTranslationKeys` are now removed. All localized messages are now sent using `Translatable` objects (usually from `KnownTranslationFactory`).
+- All usages of NBT keys now use class constants instead of hardcoded strings (except for an occasional overlooked one).
+- Built-in commands now declare their names inside the class constructor, rather than accepting them as parameters. This improves code consistency.
+- Commands now use an array for permissions internally, instead of a string separated by `;`.
+- Make use of `Item->canStackWith()` instead of `Item->equals()` wherever possible, to make the code more readable.
+- Moved command timings to `Timings`.
+- Overriding of serializers and deserializers of items and blocks is now consistently disallowed. Since overriding stuff is non-cooperative, it doesn't make any sense in plugins, which must coexist with other plugins. If you want to modify the functionality of built-in stuff, you have several alternative options:
+    - Use existing API (e.g. events, API methods) - most uses of overrides in PM4 and earlier were abuses that could have been done with events
+    - Submit feature proposals or pull requests for new API to be added (e.g. new events)
+    - Register completely custom items, and reuse behaviour from the item you want to mimic
+    - Fork PocketMine-MP and alter the code directly - this way your plugins aren't pretending to be cooperative with other plugins
+- `level.dat`, block, item, entity, tile and chunk data are now tagged with a version ID as per `VersionInfo::WORLD_DATA_VERSION`. This allows the server to apply fixes to older worlds if necessary.
+- Protocol creative inventory entries are now cached in `CreativeInventoryCache` to improve performance of initial join and game mode changes.
+- Singletons in the `pocketmine\network\mcpe\convert` package have been centralized under `TypeConverter`. In the future, this will be injected where needed, allowing different converters to be used for different sessions (useful for multiversion).
+- `BlockStateDictionary` memory usage is now reduced from 9 MB to 3.5 MB using various techniques, including string reuse and binary-encoded states.
+- `NetworkSession` disconnect APIs now accept `Translatable|string` instead of `string` to allow localized disconnect messages.
+- `NetworkSession` disconnect methods have been altered to allow specifying a different disconnect reason and disconnection screen message.
+- `RuntimeBlockMapping` has been renamed to `BlockTranslator`.
+
+# 5.0.1
+Released 3rd June 2023.
+
+## Changes
+- [`ext-pmmpthread` version 6.0.1](https://github.com/pmmp/ext-pmmpthread/releases/tag/6.0.1) is now required (for bug fixes).
