 ### Notes
 - **Non-disruptive** means that usage should not be significantly altered by the change.
@@ -43,6 +44,10 @@ PocketMine-MP has three primary branches of development.
   - Examples of **disruptive** changes include changing the way the server is run, world format changes (since those require downtime for the user to convert their world).
 - **API** includes all public and protected classes, functions and constants (unless marked as `@internal`).
   - Private members are not part of the API, **unless in a trait**.
+  - The `pocketmine\network\mcpe` package is considered implicitly `@internal` in its entirety (see its [README](src/network/mcpe/README.md) for more details).
+- Minecraft's protocol changes are considered necessary internal changes, and are **not** subject to the same rules.
+  - Protocol changes must always be released in a new minor version, since they disrupt user experience by requiring a client update.
+- BC-breaking changes to the internal network API are allowed, but only in new minor versions. This ensures that plugins which use the internal network API will not break (though they shouldn't use such API anyway).

+Plugin developers should **only** update their required API to this version if you need the changes in this build.

+
+# 4.16.0-BETA1
+Released 4th March 2023.
+
+## General
+- Added granular timings for packet encode, similar to the existing timings for packet decode.
+- Timings now covers several areas of the network system which were previously not counted by network timings, but were counted by total timings. This provides a better insight into the performance of the network system.
+
+## Performance
+- Improved performance of packet batch handling by avoiding unnecessary object allocations.
+- Improved performance of packet broadcasting when the broadcast size is below the batch threshold. Previously, the packets would be encoded once by every recipient, but now they are encoded once and then added to the send buffer of each session in their raw form.
+  - This change mostly affects servers with larger maps, where players are more widely distributed.
+
+## Build system
+- Added a new script `build/generate-bedrockdata-path-consts.php`, which must be run whenever BedrockData is updated. This script generates a class of constants with the file paths of all BedrockData files.
+
+## API
+### `pocketmine\entity`
+- The following new API methods have been added:
+  - `public Entity->getGravity() : float` - returns the entity's gravity acceleration in blocks/tick^2
+  - `public Entity->setGravity(float $gravity) : void` - sets the entity's gravity acceleration in blocks/tick^2
+
+## Internals
+- Now uses [`pocketmine/bedrock-data` 2.0.0](https://github.com/pmmp/BedrockData/releases/tag/2.0.0+bedrock-1.19.60).
+  - This version is now used by both PM4 and PM5, reducing maintenance burden.
+- Now uses [`pocketmine/bedrock-protocol` 19.3.0](https://github.com/pmmp/BedrockProtocol/releases/tag/19.3.0+bedrock-1.19.62).
+  - This version provides new APIs for handling packet batches which enabled improving performance and adding new features, such as detailed packet encode timings.
+- Crafting recipes and creative inventory data are now loaded from `recipes/legacy_recipes.json` and `recipes/legacy_creativeitems.json` respectively. Previously, these were loaded from BedrockData directly, but BedrockData 2.0 now uses a format which can't be supported in 4.x without BC breaks.
+- Added dependencies on [`pocketmine/bedrock-block-upgrade-schema`](https://github.com/pmmp/BedrockBlockUpgradeSchema) and [`pocketmine/bedrock-item-upgrade-schema`](https://github.com/pmmp/BedrockItemUpgradeSchema). These provide mapping files no longer present in BedrockData 2.0.
+- Reduced and/or eliminated most usages of `PacketBatch`, since it only appeared as a throwaway object and was therefore wasting performance.
+- `Compressor` now exposes `getCompressionThreshold()` instead of `willCompress()`, which allows determining whether a batch will be compressed without allocating it.
+- Added `pocketmine\data\bedrock\BedrockDataFiles`, an auto-generated class of constants with the file paths of all BedrockData files. This makes it easier to locate usages, detect unused files and avoid typos.

+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.

+
+### Alpha release warning
+Alpha releases are **experimental**. Features introduced in these releases are subject to change or removal.
+
+APIs which existed **prior** to this version will continue to work as normal, so plugins which use them will continue to work.
+
+### Highlights
+This version makes changes to the internal network system to improve server performance and reduce memory usage.
+
+While these changes don't affect non-internal API, they are still significant enough to warrant a new minor version, as they may break plugins which use the internal network API (not recommended).
+
+# 4.18.0-ALPHA1
+Released 16th March 2023.
+
+## General
+- Improved server performance in congested areas of the world (lots of players and/or entities in the same area).
+
+## API
+### `pocketmine\event\server`
+- The following new classes have been added:
+  - `DataPacketDecodeEvent` - called before a packet is decoded by a `NetworkSession`; useful to mitigate DoS attacks if PocketMine-MP hasn't been patched against new bugs yet
+
+## Internals
+- Introduced new system for broadcasting entity events to network sessions.
+  - This change improves performance when lots of players and/or entities are in the same area.
+  - New interface `EntityEventBroadcaster` and class `StandardEntityEventBroadcaster` have been added to implement this.
+  - All entity-specific `on*()` and `sync*()` methods have been removed from `NetworkSession` (BC break).
+  - `NetworkSession` now accepts an `EntityEventBroadcaster` instance in its constructor.
+  - `NetworkBroadcastUtils::broadcastEntityEvent()` can be used to efficiently broadcast events to unique broadcasters shared by several network sessions.
+- All network sessions now share the same `PacketSerializerContext` and `PacketBroadcaster` by default.
+  - Previously, every session had its own context, meaning that broadcast optimisations were not used, causing significant performance losses compared to 3.x.
+  - This change improves performance in congested areas by allowing reuse of previously encoded packet buffers for all sessions sharing the same context.
+  - Packet broadcasts are automatically encoded separately per unique `PacketSerializerContext` instance. This allows, for example, a multi-version fork to have a separate context for each protocol version, to ensure maximum broadcast efficiency while encoding different packets for different versions.
+  - `PacketSerializerContext` is now passed in `NetworkSession::__construct()`, instead of being created by the session.
+- `StandardPacketBroadcaster` is now locked to a single `PacketSerializer` context, reducing complexity.
+- Introduced `NetworkBroadcastUtils::broadcastPackets()`, replacing `Server->broadcastPackets()`.
+- `Server->broadcastPackets()` has been deprecated. It will be removed in a future version.
+
+# 4.18.0-ALPHA2
+Released 21st March 2023.
+
+## General
+- Included more sections of the network system in Player Network Send timings.
+- Changed the names of some timings to make them more user-friendly.
+- Removed packet IDs from `receivePacket` and `sendPacket` timings, as they were not very useful.
+- Added new specialized timers for the following:
+  - Item entity base ticking (merging)
+  - Player movement processing
+  - Entity movement processing (collision checking section)
+  - Projectile movement (all)
+  - Projectile movement processing (ray tracing section)
+
+## API
+### `pocketmine\crafting`
+- The following new API methods have been added:
+  - `CraftingManager->getCraftingRecipeIndex() : array<int, CraftingRecipe>` - returns a list of all crafting recipes
+  - `CraftingManager->getCraftingRecipeFromIndex(int $index) : ?CraftingRecipe` - returns the crafting recipe at the given index, or null if it doesn't exist
+
+### `pocketmine\inventory\transaction`
+- The following API methods have changed signatures:
+  - `CraftingTransaction->__construct()` now accepts additional arguments `?CraftingRecipe $recipe = null, ?int $repetitions = null`

+### Network
+- Introduced support for the `ItemStackRequest` Minecraft: Bedrock network protocol.
+  - This fixes a large number of inventory- and crafting-related bugs.
+  - This also improves server security by closing off many code pathways that might have been used for exploits. `TypeConverter->netItemStackToCore()` is no longer used in server code, and remains for tool usage only.
+  - This system is also significantly more bandwidth-efficient and has lower overhead than the legacy system.
+  - This now opens the gateway to easily implement lots of gameplay features which have been missing for a long time, such as enchanting, anvils, looms, and more.

+**For Minecraft: Bedrock Edition 1.19.70**
+
+### 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.
+
+### Highlights
+This version significantly improves server performance with many players and/or entities by making changes to the internal network system.
+
+It also introduces support for the newer `ItemStackRequest` protocol, which fixes many bugs and improves server security.
+
+While these changes don't affect non-internal API, they are still significant enough to warrant a new minor version, as they may break plugins which use the internal network API (not recommended).
+
+# 4.18.0
+Released 25th March 2023.
+
+## General
+- Significantly improved server performance in congested areas of the world (lots of players and/or entities in the same area).
+- Included more sections of the network system in `Player Network Send` performance timings.
+- Changed the names of some performance timings to make them more user-friendly.
+- Removed packet IDs from `receivePacket` and `sendPacket` performance timings, as they were not very useful.
+- Added new specialized performance timings for the following:
+  - Item entity base ticking (merging)
+  - Player movement processing
+  - Entity movement processing (collision checking section)
+  - Projectile movement (all)
+  - Projectile movement processing (ray tracing section)
+
+## API
+### `pocketmine\crafting`
+- The following new API methods have been added:
+  - `CraftingManager->getCraftingRecipeIndex() : array<int, CraftingRecipe>` - returns a list of all crafting recipes
+  - `CraftingManager->getCraftingRecipeFromIndex(int $index) : ?CraftingRecipe` - returns the crafting recipe at the given index, or null if it doesn't exist
+
+### `pocketmine\event\server`
+- The following new classes have been added:
+  - `DataPacketDecodeEvent` - called before a packet is decoded by a `NetworkSession`; useful to mitigate DoS attacks if PocketMine-MP hasn't been patched against new bugs yet
+
+### `pocketmine\inventory\transaction`
+- The following API methods have changed signatures:
+  - `CraftingTransaction->__construct()` now accepts additional arguments `?CraftingRecipe $recipe = null, ?int $repetitions = null`
+- The following new API methods have been added:
+  - `TransactionBuilderInventory->getActualInventory() : Inventory` - returns the actual inventory that this inventory is a proxy for
+
+## Internals
+### Network
+- Introduced new system for broadcasting entity events to network sessions.
+  - This change improves performance when lots of players and/or entities are in the same area.
+  - New interface `EntityEventBroadcaster` and class `StandardEntityEventBroadcaster` have been added to implement this.
+  - All entity-specific `on*()` and `sync*()` methods have been removed from `NetworkSession` (internals backwards compatibility break, not covered by API version guarantee).
+  - `NetworkSession` now accepts an `EntityEventBroadcaster` instance in its constructor.
+  - `NetworkBroadcastUtils::broadcastEntityEvent()` can be used to efficiently broadcast events to unique broadcasters shared by several network sessions.
+- All network sessions now share the same `PacketSerializerContext` and `PacketBroadcaster` by default.
+  - Previously, every session had its own context, meaning that broadcast optimisations were not used, causing significant performance losses compared to 3.x.
+  - This change improves performance in congested areas by allowing reuse of previously encoded packet buffers for all sessions sharing the same context.
+  - Packet broadcasts are automatically encoded separately per unique `PacketSerializerContext` instance. This allows, for example, a multi-version fork to have a separate context for each protocol version, to ensure maximum broadcast efficiency while encoding different packets for different versions.
+  - `PacketSerializerContext` is now passed in `NetworkSession::__construct()`, instead of being created by the session.
+- `StandardPacketBroadcaster` is now locked to a single `PacketSerializer` context, reducing complexity.
+- Introduced `NetworkBroadcastUtils::broadcastPackets()`, replacing `Server->broadcastPackets()`.
+- `Server->broadcastPackets()` has been deprecated. It will be removed in a future version.
+- Introduced support for the `ItemStackRequest` Minecraft: Bedrock network protocol.
+  - This fixes a large number of inventory- and crafting-related bugs.
+  - This also improves server security by closing off many code pathways that might have been used for exploits. `TypeConverter->netItemStackToCore()` is no longer used in server code, and remains for tool usage only.
+  - This system is also significantly more bandwidth-efficient and has lower overhead than the legacy system.

+    - The `InventoryTransaction` API will be redesigned in a future major version to make use of the new information provided by the `ItemStackRequest` system.
+  - `InventoryTransactionPacket` is no longer sent by the client for "regular" inventory actions. However, it is still sent when dropping items, interacting with blocks, and using items.
+- Inventory slot and content syncing is now buffered until the end of the tick. This reduces outbound network usage when the client performs multiple transactions in a single tick (e.g. crafting a stack of items).

+- Use `Vector3::zero()` instead of `new Vector3()` in some places.
+
+# 4.18.1
+Released 27th March 2023.
+
+## General
+- `RakLibInterface` now logs the name of the currently active session if a crash occurs when processing a packet. This makes it easier to reproduce bugs, which is important to be able to fix them.
+- Added more detailed debugging information to `InventoryManager->syncSelectedHotbarSlot()`.
+
+## Fixes
+- Fixed server crash when attempting to drop more of an item from a stack than available in the inventory.
+- Fixed packet processing errors when editing writable books.
+- Fixed packet processing errors when shift-clicking on the recipe book to craft recipes which draw from a large number of inventory slots.
+
+# 4.18.2
+Released 29th March 2023.
+
+## Fixes
+- Fixed players being unable to join due to the appearance of a new `x5t` field in the JWT header of Xbox Live authentication tokens.
+- Fixed items' durability appearing to reset when moving them around in the inventory.
+
+# 4.18.3
+Released 5th April 2023.
+
+## Fixes
+- Fixed Average Players not being shown on timings reports when custom player classes are used.
+- Fixed incorrect tick violation calculation in timings reports.
+- Fixed not being able to add or remove items from the offhand slot.
+- Fixed creative inventory item count corruption when taking items (some players would see 64x items in the creative inventory after rejoining or changing gamemode).
+- Fixed not being able to drop items directly from the creative inventory on mobile.
+- Fixed `DataPacketReceiveEvent` not being called for packets sent by `EntityEventBroadcaster`.
+- `CreativeInventory::getItem()` and `CreativeInventory::getAll()` now return cloned itemstacks, to prevent accidental modification of the creative inventory.
+
+# 4.18.4
+Released 10th April 2023.
+
+## Fixes
+- Fixed movement becoming broken when the player moves at high speed (e.g. due to high levels of the Speed effect).
+- Updated dependencies to get fixes in `pocketmine/nbt` and `pocketmine/bedrock-protocol`.
+
+## Internals
+### Network
+- Game packets are now rate-limited in a similar manner to packet batches. This helps to more effectively mitigate certain types of DoS attacks.
+- Added a new class `PacketRateLimiter`, implementing functionality previously baked directly into `NetworkSession` in a more generic way to allow reuse.

+
+### 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.

+
+### Highlights
+This version introduces support for a new, more advanced version of Timings.
+This improved system provides more detail than the old system, and supports being displayed in a tree view, making it much easier to see which timers contribute to which other timers.
+
+In addition, some minor performance improvements have been made, along with a couple of minor API additions.
+
+# 4.19.0
+Released 11th April 2023.
+
+## General
+- Updated the Timings system.
+  - Timings records now include parent information, allowing them to be displayed in a tree view (e.g. https://timings.pmmp.io/?id=303556).
+  - Timings records now include additional information, such as Peak (max time spent on any single tick), and Ticks (number of ticks the timer was active on).
+  - New timings have been added for every event.
+  - A new timer `Player Network Send - Pre-Spawn Game Data` has been added, and covers most of the time spent handling `ResourcePackClientResponsePacket`, giving a clearer picture of what's happening.
+- Improved performance of the plugin event system.
+  - By introducing some caching, the event system now has 90% less overhead than in previous versions.
+- Improved performance of the random chunk ticking system.
+  - The selection of ticked random chunks, and their validation for ticking, is now cached. This significantly reduces the overhead of chunk selection.
+  - Factions servers and other game modes with big maps and sparsely populated areas will see the most benefit from this change.
+  - Real-world performance benefit of this change is anywhere from 0-20%, depending on server type and configuration.
+- The `timings paste` command now logs a debug message with the server response on failure to paste a timings report.
+
+## API
+### `pocketmine\entity\object`
+- The following API constants have been added:
+  - `ExperienceOrb::DEFAULT_DESPAWN_DELAY` - the default delay in ticks before an experience orb despawns
+  - `ExperienceOrb::NEVER_DESPAWN` - magic value for `setDespawnDelay()` to make an experience orb never despawn
+  - `ExperienceOrb::MAX_DESPAWN_DELAY` - the maximum delay in ticks before an experience orb despawns
+- The following API methods have been added:
+  - `public ExperienceOrb->getDespawnDelay() : int` - returns the delay in ticks before this experience orb despawns
+  - `public ExperienceOrb->setDespawnDelay(int $despawnDelay) : void` - sets the delay in ticks before this experience orb despawns
+- The following properties have been deprecated
+  - `ExperienceOrb->age` - superseded by despawn delay methods
+
+### `pocketmine\event`
+- The following API methods have been added:
+  - `public HandlerList->getListenerList() : list<RegisteredListener>` - returns an ordered list of handlers to be called for the event
+
+### `pocketmine\player`
+- The following API methods have behavioural changes:
+  - `ChunkSelector->selectChunks()` now yields the distance in chunks from the center as the key, instead of an incrementing integer.
+- The following classes have been deprecated:
+  - `PlayerChunkLoader` (this was technically internal, but never marked as such)
+
+### `pocketmine\timings`
+- The following API constants have been deprecated:
+  - `Timings::INCLUDED_BY_OTHER_TIMINGS_PREFIX` - this is superseded by timings group support (see `Timings::GROUP_BREAKDOWN`)
+- The following API constants have been added:
+  - `Timings::GROUP_BREAKDOWN` - this group makes a timer appear in the `Minecraft - Breakdown` section of a timings report
+- The following API methods have been added:
+  - `public TimingsHandler->getGroup() : string` - returns the name of the table in which this timer will appear in a timings report
+- The following API methods have changed signatures:
+  - `TimingsHandler->__construct()` now accepts an additional, optional `string $group` parameter, which defaults to `Minecraft`.
+
+### `pocketmine\world`
+#### Highlights
+Ticking chunks is now done using the `ChunkTicker` system, which has a much more fine-grained API than the old `TickingChunkLoader` system, as well as better performance.
+It works similarly to the `ChunkLoader` system, in that chunks will be ticked as long as at least one `ChunkTicker` is registered for them.
+
+#### API changes
+- The following classes have been deprecated:
+  - `TickingChunkLoader` - this has been superseded by the more powerful and performant `ChunkTicker` APIs
+- The following classes have been added:
+  - `ChunkTicker` - an opaque object used for `registerTickingChunk()` to instruct the `World` that we want a chunk to be ticked
+- The following API methods have been added:
+  - `public World->registerTickingChunk(ChunkTicker $ticker, int $chunkX, int $chunkZ) : void` - registers a chunk to be ticked by the given `ChunkTicker`
+  - `public World->unregisterTickingChunk(ChunkTicker $ticker, int $chunkX, int $chunkZ) : void` - unregisters a chunk from being ticked by the given `ChunkTicker`
+
+# 4.19.1
+Released 14th April 2023.
+
+## Fixes
+- Fixed inventory rollbacks when spreading items in ender chests.
+- Fixed inventory rollbacks when shift-clicking to craft and the outputs would have been split across multiple inventory slots.
+- Fixed incorrect spawn terrain generation for newly created worlds.
+- Fixed `chunk-ticking.tick-radius` not disabling chunk ticking when set to `0`.
+- Fixed chunks not being ticked if they previously left a player's simulation distance without leaving their view distance.
+- Fixed height of collision boxes for Grass Path and Farmland blocks.
+
+# 4.19.2
+Released 14th April 2023.
+
+## Fixes
+- 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.

+## 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.
