 ### Requirements
 The following are required as a minimum for pull requests. PRs that don't meet these requirements will be declined unless updated to meet them.
 
-#### Licensing
-PocketMine-MP is licensed under [LGPLv3 license](LICENSE).
-By proposing a pull request, you agree to your code being distributed within PocketMine-MP under the same license.
-If you take code from other projects, that code MUST be licensed under an LGPL-compatible license.
-
-#### PRs should be about exactly ONE thing
-If you want to make multiple changes, those changes should each be contributed as separate pull requests. **DO NOT** mix unrelated changes.
-
-#### PRs must not include unnecessary/unrelated changes
-Do not include changes which aren't strictly necessary. This makes it harder to review a PR, because the code diff becomes larger and harder to review.
-This means:
-- don't reformat or rearrange existing code
-- don't change things that aren't related to the PR's objective
-- don't rewrite existing code just to make it "look nicer"
-- don't change PhpDocs to native types in code you didn't write
-
-#### Tests must be provided
-Where possible, PHPUnit tests should be written for new or changed code.
-If that's not possible (e.g. for in-game functionality), the code must be tested manually and details of the tests done must be provided.
-**Simply saying "Tested" is not acceptable** and will lead to your PR being declined.
-
-#### Comments and documentation must be written in American English
-English is the shared languages of all current maintainers.
-
-#### Code must be in the PocketMine-MP style
-It's your responsibility to ensure your code matches the formatting and styling of the rest of the code.
-If you use PhpStorm, a `Project` code style is provided, which you can use to automatically format new code.
-You can also use [`php-cs-fixer`](https://github.com/FriendsOfPHP/PHP-CS-Fixer) to format your code.
+- **All code must be licensed under the [LGPLv3 license](LICENSE)** as per PocketMine-MP's own license, or a compatible license.
+  - By proposing a pull request, you agree to your code being distributed within PocketMine-MP under the same license.
+  - If you take code from other projects, that code MUST be licensed under an LGPL-compatible license.
+- **PRs should be about ONE thing**
+  - If you want to make multiple changes, those changes should each be contributed as separate pull requests. **DO NOT** mix unrelated changes.
+  - **Do not include unnecessary changes.** This makes the code diff larger and more noisy, making it harder to review.
+    - Don't change things that aren't related to the PR's objective

+    - Don't rewrite existing code just to make it "look nicer"
+    - Don't change PhpDocs to native types in code you didn't write, unless that's the objective of the PR
+- **Test code changes, and tell us what tests have been done.**
+  - Where possible, PHPUnit tests should be written for new or changed code. If that's not possible (e.g. for in-game functionality), the code must be tested manually and details of the tests done must be provided.

+  - You can also use [`php-cs-fixer`](https://github.com/FriendsOfPHP/PHP-CS-Fixer) to format your code.
+- **Use `final` and `private` wherever possible**.
+  - Changing from `private` to `protected` or `final` to non-`final` doesn't break backwards compatibility, but the opposite does.
+  - `private` and `final` also enable certain performance optimizations which are otherwise not possible.
+  - `private` members can be freely changed, added and removed in the future, so it's ideal for internal functions. Abusing `protected` makes internal improvements inconvenient.
+  - "Let's leave it protected/public in case someone needs it for ... idk what" is **not a valid reason to expose things**. If there isn't a clear reason for something to be accessible from the outside, don't expose it.
+  - **This is a lesson learned through years of experience.** You may not like it, but it's for the best.
+- **Immutable things are almost always preferred.**
+  - Do not add unnecessary setters or public writable properties to classes. As above, "Let's leave it in case someone needs it" is **not a valid reason to expose things**.
+  - Mutable classes and properties are unpredictable, since code has no way to know if the object it's working with might be randomly modified by another part of the code. This makes it harder to maintain code and debug issues.
+  - Most classes exist only to hold some data. These are called "data transfer objects" (DTOs). These types of classes should pretty much always be immutable.
+  - Make use of `final`, `private` and `readonly` modifiers.
 
 ### Recommendations
-
+- **Be patient.** Reviewing pull requests takes a lot of time and energy, and maintainers are often unavailable or busy. Your PR might not receive attention for a while.
+  - Remember, PRs with small diffs are much easier to review. Small PRs are generally reviewed and merged much faster than large ones.
+- **Start small.** Try fixing minor bugs or doing something isolated (e.g. adding a new block or item) before attempting larger changes.
+  - This helps you get familiar with the codebase, the contribution process, and the expectations of maintainers.
+  - Check out the [issues page]() for something that you could tackle without too much effort.
+- **Do not copy-paste other people's code**. Many PRs involve discussion about the changes, and changes are often requested by reviewers. If you don't understand the code you're copy-pasting, your PR is likely to fail.
 - **Do not edit code directly on github.com.** We recommend learning how to use [`git`](https://git-scm.com). `git` allows you to "clone" a repository onto your computer, so that you can make changes using an IDE.
 - **Use an IDE, not a text editor.** We recommend PhpStorm or VSCode.
+- **Do not make large pull requests without an RFC.**
+  - Large changes should be discussed beforehand using the [RFC / Change Proposal](#rfcs--change-proposals) process.
+  - Large changes are much harder to review, and are more likely to be declined if maintainers don't have a good idea what you're trying to do in advance.
 - **Create a new branch on your fork for each pull request.** This allows you to use the same fork to make multiple pull requests at the same time.
+- **Make your PR diff as small as possible.** Smaller PRs are **much more likely** to be accepted, as they are easier to review.
+  - Avoid moving code around in files if possible.
+  - Don't make random CS changes. This makes the diff noisier and harder to review.
 - **Use descriptive commit titles.** You can see an example [here](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).
-- **Do not include multiple unrelated changes in one commit.** An atomic style for commits is preferred - this means that changes included in a commit should be part of a single distinct change set. See [this link](https://www.freshconsulting.com/atomic-commits/) for more information on atomic commits. See the [documentation on `git add`](https://git-scm.com/docs/git-add) for information on how to isolate local changes for committing.
-- **Your pull request will be checked and discussed in due time.** Since the team is scattered all around the world, your PR may not receive any attention for some time.
-- **Do not make large pull requests without an RFC.** Large changes should be discussed beforehand using the [RFC / Change Proposal](#rfcs--change-proposals) process. Large changes are much harder to review and are more likely to be declined if maintainers don't have a good idea what you're trying to do in advance.
-- **Do not copy-paste code**. There are potential license issues implicit with copy-pasting, and copy-paste usually indicates a lack of understanding of the actual code. Copy-pasted code is obvious a mile off and **any PR like this is likely to be closed**. If you want to use somebody else's code from a Git repository, **use [GIT's cherry-pick feature](https://git-scm.com/docs/git-cherry-pick)** to cherry-pick the commit.
+- **Split unrelated changes into multiple commits.**
+  - An atomic style for commits is preferred - this means that changes included in a commit should be part of a single distinct change set.
+  - If you need to use "and" or "multiple changes" in your commit message, the commit probably needs to be split up. There are exceptions, but this is a good rule of thumb.
+  - See [this link](https://www.freshconsulting.com/atomic-commits/) for more information on atomic commits.
+  - See the [documentation on `git add -i` or `git add -p`](https://git-scm.com/docs/git-add) for information on how to split up local changes for committing.

-## Getting started
+## What is this?
+PocketMine-MP is a highly customisable server software for Minecraft: Bedrock Edition, built from scratch in PHP, with over 10 years of history.
+
+If you're looking to create a Minecraft: Bedrock server with **custom functionality**, look no further.
+
+- 🧩 **Powerful plugin API** - extend and customise gameplay as you see fit
+- 🗺️ **Rich ecosystem** and **large developer community** - find plugins easily and learn to develop your own
+- 🌐 **Multi-world support** - offer a more varied game experience to players without transferring them to other server nodes
+- 🏎️ **Performance** - get 100+ players onto one server (depending on hardware and plugins)
+- ⤴️ **Continuously updated** - new Minecraft versions are usually supported within days
+
+## :x: PocketMine-MP is NOT a vanilla Minecraft server software.
+**It is poorly suited to hosting vanilla survival servers.**
+It doesn't have many features from the vanilla game, such as vanilla world generation, redstone, mob AI, and various other things.
+
+If you just want to play **vanilla survival multiplayer**, consider using the [official Minecraft: Bedrock server software](https://minecraft.net/download/server/bedrock) instead of PocketMine-MP.
+
+If that's not an option for you, you may be able to add some of PocketMine-MP's missing features using plugins from [Poggit](https://poggit.pmmp.io/plugins), or write plugins to implement them yourself.
+
+## Getting Started

+# 5.10.0
+Released 14th December 2023.
+
+**For Minecraft: Bedrock Edition 1.20.50**
+
+This is a minor feature release, including new gameplay features and minor performance improvements.
+
+**Plugin compatibility:** Plugins for previous 5.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe`  or `pocketmine\data` namespace.

+
+## General
+- PHP 8.2 is now used by default. PHP 8.1 is still supported, but will be removed in a future 5.x release.
+- Improved timings reports by removing `Breakdown` timings group. This group serves no purpose with tree timings and made for confusing reading.
+
+## Performance
+- Improved performance of `Block::encodeFullState()` in most conditions. This in turn improves performance of `World::setBlock()` and `World::setBlockAt()`.
+- Improved network compression performance by avoiding unnecessary object allocations.
+- Timings now report time spent in individual `Snooze` handlers, making it easier to debug performance issues.
+
+## Gameplay
+### Blocks
+- Implemented crop growth speed modifiers.
+  - The following things now positively affect crop growth speed:
+    - Being planted on or being adjacent to farmland (hydrated farmland offers a larger benefit than dry farmland)
+    - Potential light level of at least 9
+    - Being planted in rows with space between them (or a different type of crop)
+  - The following things now negatively affect crop growth speed:
+    - Improper arrangement (e.g. the same crop on all sides)
+    - Insufficient light level (below 9)
+  - Poorly arranged crops will grow slower in this version. Past versions behaved as if crops were always planted in ideal conditions.
+  - Crops planted in ideal conditions will grow at the same speed as before.
+
+### Items
+- Added the following new items:
+  - All types of Smithing Template
+- Pitcher Pod is now correctly registered. In previous versions, it was mapped to the Pitcher Crop block, causing incorrect name display in commands.
+
+## Internals
+- Cleaned up various getter usages where direct property access is possible.
+- Avoided unnecessary repeated getter calls in some loops.
+- `NetworkSession` may now track `string` instead of `CompressBatchPromise` when a batch was synchronously compressed. This significantly reduces object allocations and improves performance.
+- `NetworkSession` now sends less information to clients on login validation failure. This avoids leaking potentially sensitive error information to clients.
+  - Clients can correlate their disconnects with server-side logs using the `Error ID` shown on the disconnect screen.

+## API
+### `pocketmine\block`
+- The following new classes have been added:
+  - `utils\LightableTrait` - used by blocks with `getLit()` and `setLit()` methods
+- The following methods have been deprecated:
+  - `Block->isSolid()` - this method returns confusing results which don't match expectations and no one really knows what it actually means
+- `CocoaBlock` now extends `Flowable` to match vanilla Minecraft behaviour.
+
+### `pocketmine\plugin`
+- `PluginManager->registerEvent()` now throws an exception when given a generator function for the event handler.
+- `PluginManager->registerEvents()` now throws an exception if any of the detected event handlers are generator functions. Use `@notHandler` to have the function ignored if intended.
+
+### `pocketmine\promise`
+- The following methods have been added:
+  - `public static Promise::all(list<Promise> $promises) : Promise` - returns a promise that is resolved once all given promises are resolved, or is rejected if any of the promises are rejected.
+
+### `pocketmine\scheduler`
+- The following methods have been deprecated:
+  - `AsyncWorker->getFromThreadStore()` - use class static properties for thread-local storage
+  - `AsyncWorker->removeFromThreadStore()`
+  - `AsyncWorker->saveToThreadStore()`
+
+## Documentation
+- Improved documentation of various methods in `Block`.
+
+## Gameplay
+- The following new items have been added:
+  - Name Tag
+
+## Internals
+- Removed specialization of shutdown logic for `Thread` vs `Worker` (no specialization is required).
+- Authentication system no longer accepts logins signed with the old Mojang root public key.
+- ID to enum mappings in `pocketmine\data` now use a new `match` convention to allow static analysis to ensure that all enum cases are handled.
+- Updated version of `pocketmine/bedrock-protocol` allows avoiding decoding of some itemstack data from the client in most cases, improving performance.
+
+# 5.12.1

+
+## Dependencies
+- Updated `pocketmine/math` dependency to [`1.0.0`](https://github.com/pmmp/Math/releases/tag/1.0.0).
+- Updated `pocketmine/nbt` dependency to [`1.0.0`](https://github.com/pmmp/NBT/releases/tag/1.0.0).
+
+## Performance
+- Some events are now no longer fired if no handlers are registered.
+  - This improves performance by avoiding unnecessary object allocations and function calls.
+  - Events such as `DataPacketReceiveEvent`, `DataPacketSendEvent` and `PlayerMoveEvent` are optimized away almost completely by this change, offering some much-needed performance gains.
+- Significantly improved performance of small moving entities, such as dropped items.
+  - This was achieved by a combination of changes, which together improved observed performance with 2000 item entities moving in water by 30-40%.
+  - The benefit of this will be most noticeable in SkyBlock servers, where large cactus farms can generate thousands of dropped items.
+- `World->getCollisionBoxes()` now uses an improved search method, which reduces the work done by the function by almost 90% for small entities.
+  - This improves performance of collision detection for small entities, such as dropped items.
+
+## Gameplay
+### General
+- Implemented enchanting using an enchanting table (yes, finally!)
+  - Thanks to [@S3v3Nice](https://github.com/S3v3Nice) for investing lots of time and effort into developing this.
+  - Since this feature is quite complex, it's possible there may be bugs. Please be vigilant and report any issues you find.
+
+### Blocks
+- The following new blocks have been implemented:
+  - Pink Petals
+- Pressure plates are now functional, in the sense that they react when entities stand on them and perform the correct logic.
+  - Note that since redstone is not yet implemented, pressure plates do not activate any redstone devices, similar to buttons and levers.
+- Signs can now be edited by right-clicking them.
+- Signs can now be waxed using a honeycomb, which prevents them from being edited.
+
+### Items
+- The following new items have been implemented:
+  - Enchanted Book
+
+## API
+### `pocketmine\block`
+- The following new API methods have been added:
+  - `public Block->getEnchantmentTags() : list<string>` returns a list of strings indicating which types of enchantment can be applied to the block when in item form
+  - `public BlockTypeInfo->getEnchantmentTags() : list<string>`
+  - `protected PressurePlate->getActivationBox() : AxisAlignedBB` - returns the AABB entities must intersect with in order to activate the pressure plate (not the same as the visual shape)
+  - `protected PressurePlate->hasOutputSignal() : bool` - returns whether the pressure plate has an output signal - this should be implemented by subclasses
+  - `protected PressurePlate->calculatePlateState() : array{Block, ?bool}` - returns the state the pressure plate will change to if the given list of entities are standing on it, and a bool indicating whether the plate activated or deactivated this tick
+  - `protected PressurePlate->filterIrrelevantEntities(list<Entity> $entities) : list<Entity>` - returns the given list filtered of entities that don't affect the plate's state (e.g. dropped items don't affect stone pressure plates)
+  - `public BaseSign->isWaxed() : bool`
+  - `public BaseSign->setWaxed(bool $waxed) : $this`
+  - `public inventory\EnchantInventory->getInput() : Item`
+  - `public inventory\EnchantInventory->getLapis() : Item`
+  - `public inventory\EnchantInventory->getOutput(int $optionId) : ?Item` - returns the item that would be produced if the input item was enchanted with the selected option, or `null` if the option is invalid
+  - `public inventory\EnchantInventory->getOption(int $optionId) : EnchantOption` - returns the enchanting option at the given index
+- The following API methods have signature changes:
+  - `BlockTypeInfo->__construct()` now accepts an optional `list<string> $enchantmentTags` parameter
+  - `PressurePlate->__construct()` now accepts an optional `int $deactivationDelayTicks` parameter
+  - `WeightedPressurePlate->__construct()` now accepts optional `int $deactivationDelayTicks` and `float $signalStrengthFactor` parameters
+  - `SimplePressurePlate->__construct()` now accepts an optional `int $deactivationDelayTicks` parameter
+- The following new classes have been added:
+  - `PinkPetals`
+  - `utils\BlockEventHelper` - provides helper methods for calling block-related events
+- The following classes have been deprecated:
+  - `WeightedPressurePlateLight`
+  - `WeightedPressurePlateHeavy`
+
+### `pocketmine\entity`
+- The following new API methods have been added:
+  - `public Human->getEnchantmentSeed() : int` - returns the current seed used to randomize options shown on the enchanting table for this human
+  - `public Human->setEnchantmentSeed(int $seed) : void`
+  - `public Human->regenerateEnchantmentSeed() : void` - returns a new randomly generated seed which can be set with `setEnchantmentSeed()`

+- Fixed support conditions for hanging roots, cave vines and dead bushes.
+- Fixed connection conditions for fences, glass panes, iron bars, and walls.
+
+# 5.6.1
+Released 20th October 2023.
+
+## Performance
+- Improved performance of cactus growth by disabling neighbour updates when only the age property was updated. While this isn't a perfect solution, it provides significant performance gains for servers with large cactus farms.
+
+## Fixes
+- Fixed `tools/generate-bedrock-data-from-packets.php` incorrectly interpreting network meta as blockstates in some cases (broken crafting recipes).
+- Fixed crafting recipes involving beds, skulls and some other items not working correctly (incorrectly interpreted data).
+- Fixed crashes when flower pot or cauldron blockentities exist in places where they shouldn't (leftovers from upgraded PM3 worlds).
+- Fixed `Entity->broadcastSound()` not firing `WorldSoundEvent` (bypassing internal sound system).

+
+## General
+- Neighbour block updates now have a separate timer for timings. Previously, these were counted under `Scheduled Block Updates`, which was misleading.
+
+## Performance
+- `LightUpdate` now avoids attempting to propagate back in the same direction the light came from. This produces a small performance improvement of around 6% in light propagation.
+- Improved worst-case (non-cached) performance of `World::getCollisionBlocks()` (and its successor `World::getBlockCollisionBlocks()`).
+  - While 5.5.0 introduced caching at the `World` level for AABBs, the cache was rarely useful due to entity and player movement being too unpredictable. This meant that most users saw a performance degradation with lots of moving entities, except in specific situations.
+  - Performance for fetching non-cached AABBs for a cell is now improved by 2x. Overall performance benefit to a server depends on the number of entities and players.
+- Added cache for hydrated farmland blocks to remember the last known location of nearby water.
+  - If nearby water sources are not changed, this cache allows hydrated farmland to completely avoid checking up to 161 nearby blocks for water after the first check.
+  - Tests with large wheat farms showed a 25% performance improvement in overall server performance compared to previous 5.x versions.
+- Migrated various internal enums to native PHP 8.1 enums. Bypassing magic `__callStatic()` accessors improved performance in many areas, although it's hard to quantify the exact benefit.
+- Made use of `Facing::OFFSET` constant in various places to avoid unnecessary `Vector3` and `Position` object allocations. Many pathways benefit from this, including neighbour block updates (due to faster `Block::getSide()` and less useless objects).
+- Avoided clearing block AABB caches except when strictly necessary. Previously, the cache was wiped every time blocks were read from the world, making them mostly useless.
+- Avoided random updates on blocks which have reached their final state, such as fully-grown crops. This produces a minimal performance improvement.
+- Removed useless checks in some `World` hot paths.
+
+## API
+### General
+- All enums have been migrated to native PHP 8.1 enums.
+  - For now, the old APIs and accessors are still usable (via `LegacyEnumShimTrait`), but these will be removed in the next major release.
+  - `EnumTrait` has been deprecated, and will be removed in the next major release.
+  - Migration for most plugin developers will simply involve deleting `()` from the end of enum case usages, which is a trivial change and also improves performance.
+  - Plugin usages of `EnumTrait` are encouraged to move to native enums, optionally using `LegacyEnumShimTrait` to provide backwards compatibility.
+    - See [this code](https://github.com/pmmp/PocketMine-MP/blob/9832fe899f13a8ea47cc9d73de7088f7775a12f5/src/block/utils/DyeColor.php#L85-L107) for an example of how to associate properties with enum cases (since native enums don't support this directly).
+  - Thanks to improvements in `RuntimeDataDescriber`, any native enum can now be used as a custom block's state property.
+
+### `pocketmine\block`
+- The following classes have been added:
+  - `utils\AgeableTrait` - used by blocks which have an age property, such as crops
+  - `utils\StaticSupportTrait` - used by blocks which have the same support requirements regardless of their state, such as crops
+
+### `pocketmine\data\runtime`
+- The following API methods have been added:
+  - `public RuntimeDataDescriber->boundedIntAuto(int $min, int $max, int &$value) : void` - similar to `boundedInt()`, but automatically calculates the needed number of bits based on the given min/max
+  - `public RuntimeDataDescriber->enum(T extends \UnitEnum &$case) : void` - describes any native PHP 8.1 enum case
+  - `public RuntimeDataDescriber->enumSet(array<int, T extends \UnitEnum> &$set, array<int, T extends \UnitEnum> $allCases) : void` - describes a set of enum cases (similar to bitflags)
+- The following API methods have been deprecated:
+  - `RuntimeDataDescriber->bellAttachmentType()` - use `enum()` instead
+  - `RuntimeDataDescriber->boundedInt()` - use `boundedIntAuto()` instead
+  - `RuntimeDataDescriber->brewingStandSlots()` - use `enumSet()` instead
+  - `RuntimeDataDescriber->copperOxidation()` - use `enum()` instead
+  - `RuntimeDataDescriber->coralType()` - use `enum()` instead
+  - `RuntimeDataDescriber->dirtType()` - use `enum()` instead

+  - `RuntimeDataDescriber->slabType()` - use `enum()` instead
+  - `RuntimeDataDescriber->suspiciousStewType()` - use `enum()` instead
+
+### `pocketmine\player`
+- `TitleID` is now included in `PlayerInfo` metadata for plugin consumption.
+
+### `pocketmine\world`
+- The following API methods have been added:
+  - `public World->getBlockCollisionBoxes(AxisAlignedBB $bb) : list<AxisAlignedBB>` - similar to `getCollisionBoxes` but exclusively for blocks, avoiding the need for conditionally useless parameters
+- The following API methods have been deprecated:
+  - `World->getCollisionBoxes()` - use `getBlockCollisionBoxes()` instead (alongside `getCollidingEntities()` if entity collision boxes are also required)
+
+### `pocketmine\utils`
+- The following classes have been deprecated:
+  - `EnumTrait` - use native PHP 8.1 enums instead
+- The following classes have been added:
+  - `LegacyEnumShimTrait` - can be `use`d by native PHP 8.1 enums to provide the same API as `EnumTrait`
+
+## Gameplay
+### Blocks
+- Implemented the following blocks:
+  - Amethyst
+  - Amethyst Cluster
+  - Chiseled Bookshelf
+  - Crimson Roots
+  - Pitcher Crop
+  - Pitcher Plant
+  - Torchflower
+  - Torchflower Crop
+  - Warped Roots
+
+### Items
+- Implemented the following items:
+  - Pitcher Pod
+  - Torchflower Seeds
+
+## Internals
+- `Farmland` block now has an extra property (`waterPositionIndex`) stored in its blockstate ID to track the position of nearby water. This property is not saved to disk, and is only used for caching.
+- The format of internal blockstate ID has been updated.
+  - The lower `11` bits are now reserved for state data (previously `8` bits). This increase facilitates the new cache for `Farmland` blocks.
+  - The state data bits are now XOR'd with the `xxh3` of the block's type ID, instead of being directly XOR'd with the type ID.
+    - This XOR improves the distribution of the lower bits of the blockstate ID, which is important for hashtable indexing to minimize collisions.
+    - Previously, the lower bits were XOR'd with the type ID directly, but the effectiveness of this reduced as more state data bits were added.
+    - `xxh3` produces consistently good results for this purpose regardless of the number of state data bits allocated.
+    - Hash collisions with blockstate IDs are reduced by 50% with this change, which is a happy side effect.
+  - This is backwards-incompatible, so anyone saving internal blockstate IDs on disk or in a DB will be burned by this change (though they shouldn't have been doing that anyway).
+- Removed code generation step for `RuntimeDataDescriber` enum serialization. All described enums now use PHP 8.1 native enums, which can be described without codegen using `RuntimeDataDescriber->enum()`.
+- Added `DeprecatedLegacyEnumAccessRule` custom PHPStan rule to flag legacy `EnumTrait` case accessors.
+- Cleaned up remaining hardcoded `Config` keys in `SetupWizard`. These usages now use auto-generated constants like the rest of the codebase.
+
+# 5.8.2
+Released 9th November 2023.
+
+## Performance
+- Improved performance of small packet zero-compression (unintended use of slow zlib compressor instead of fast libdeflate one).
+  - This affected the majority of outbound packets, as most packets are below the 256-byte threshold for compression.
+  - This faster method is over 20x faster than the old method, producing noticeable performance gains for large servers.
+
+## Fixes
+- Fixed melons and pumpkins not growing.
+- Fixed melon and pumpkin stems not attaching to the grown melon/pumpkin.
+- Fixed iron and gold ores not being affected by the Fortune enchantment.
+- Fixed ancient debris burning in lava.
+- Fixed sign (front) text loading from vanilla world saves (back text is not yet supported).
+
+## Internals
+- Removed bogus optimization from `tools/generate-blockstate-upgrade-schema.php` that could cause incorrect `remappedStates` generation when some of the states stayed under the old ID.
+- Fixed possible crash in `BlockStateUpgrader` name flattening rule handling with invalid blockstate NBT data.
