Pull registration functionality out of BlockTypeIds

This solves the following issues:
- Conflicts on BlockTypeIds every time someone makes a PR to add a new block
- Type IDs not consistent on different threads

We still have an auto assigned type number internally, which is used to compute
state IDs for runtime chunk storage. However, this is not directly exposed to
plugins, and is fully dynamic.
FastChunkSerializer, instead of directly passing state IDs to the next thread,
now deconstructs state IDs into their type number and state data componets,
and writes a string type name + state data separately. This allows the blocks
to be consistently decoded on the destination thread, particularly when custom
blocks are involved, as custom blocks are expected to claim unique string type
IDs

Plugins implementing custom blocks **may** use their Minecraft save ID as their
type ID, however this is not required. A type ID must, however, be globally
unique and must not conflict with any other blocks.

I haven't yet measured the performance impact to FastChunkSerializer from this
change, however, I do expect some minor performance degradation, since individual
calls on BinaryStream are slower than a bulk pack() / unpack() call.

   - 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.

 - **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.

+

+deprecations, and improvements to timings.
+

+
+## General
+- `/timings` now supports collecting timings from async task workers. These new timings will be shown alongside `Full Server Tick` timings, but will not be counted in total load.
+- Added `/xp` command.
+- `start.sh` will now emit warnings when the server process exits with an unusual exit code. This helps to detect unexpected segmentation faults and other kinds of native errors.
+
+## Gameplay
+- Added the following new items:
+  - End Crystal
+  - Goat Horn (all variants)
+  - Ice Bomb (from Education Edition)
+  - Recovery Compass
+- Added the following enchantments:
+  - Frost Walker
+- Sugarcane now self-destructs when there is no water adjacent to the base block.
+- Added basic support for middle-clicking on entities to get their spawn eggs.
+- Added sounds when drinking potions.
+- Eating food is now allowed in creative mode and in peaceful difficulty.
+
+## API
+### `pocketmine\block`
+- Extracted `MultiAnyFacingTrait` and `MultiAnySupportTrait` from `GlowLichen` to enable reuse in other blocks.
+- The following API methods have been deprecated:
+  - `Campfire->getInventory()` - this was added by mistake and can't be well-supported given the way that blocks work
+
+### `pocketmine\command`
+- The following classes have been added:
+  - `ClosureCommand` - allows registering a closure to execute a command
+
+### `pocketmine\event`
+- Added APIs to `PlayerInteractEvent` to allow toggling item and block interactions.
+  - This allows various customisations, such as allowing interactions when sneaking, selectively disabling item or block reactions, etc.
+  - If both item and block interactions are disabled, the event is **not** cancelled (blocks can still be placed).
+  - The following API methods have been added:
+    - `public PlayerInteractEvent->setUseBlock(bool $useBlock) : void`
+    - `public PlayerInteractEvent->setUseItem(bool $useItem) : void`
+    - `public PlayerInteractEvent->useBlock() : bool` - returns whether the block can respond to the interaction (toggling levers, opening/closing doors, etc).
+    - `public PlayerInteractEvent->useItem() : bool` - returns whether the item can respond to the interaction (spawn eggs, flint & steel, etc).
+- The following new classes have been added:
+  - `player\PlayerEntityPickEvent` - called when a player middle-clicks on an entity
+
+### `pocketmine\inventory\transaction`
+- The following API methods have been deprecated:
+  - `InventoryAction->onAddToTransaction()`
+
+### `pocketmine\permission`
+- The following API methods have been deprecated:
+  - `PermissionManager->getPermissionSubscriptions()`
+  - `PermissionManager->subscribeToPermission()`
+  - `PermissionManager->unsubscribeFromAllPermissions()`
+  - `PermissionManager->unsubscribeFromPermission()`
+
+### `pocketmine\plugin`
+- The following classes have been deprecated:
+  - `DiskResourceProvider`
+  - `ResourceProvider`
+
+### `pocketmine\promise`
+- `Promise::all()` now accepts zero promises. This will return an already-resolved promise with an empty array.
+
+### `pocketmine\scheduler`
+- Added PHPStan generic types to `TaskHandler` and related APIs in `TaskScheduler` and `Task`.
+- The following API methods have been deprecated
+  - `AsyncTask->publishProgress()`
+  - `AsyncTask->onProgressUpdate()`
+
+### `pocketmine\timings`
+- Timings can now notify other code when timings are enabled/disabled, reloaded, or collected.
+  - The intent of this is to facilitate timings usage on other threads, and have the results collected into a single timings report.
+  - Timings cannot directly control timings on other threads, so these callbacks allow plugins to use custom mechanisms to toggle, reset and collect timings.
+  - PocketMine-MP currently uses this to collect timings from async task workers. More internal threads may be supported in the future.
+- The following API methods have been added:
+  - `public static TimingsHandler::getCollectCallbacks() : ObjectSet<\Closure() : list<Promise<list<string>>>` - callbacks for (asynchronously) collecting timings (typically from other threads). The returned promises should be resolved with the result of `TimingsHandler::printCurrentThreadRecords()`.
+  - `public static TimingsHandler::getReloadCallbacks() : ObjectSet<\Closure() : void>` - callbacks called when timings are reset
+  - `public static TimingsHandler::getToggleCallbacks() : ObjectSet<\Closure(bool $enable) : void>` - callbacks called when timings are enabled/disabled
+  - `public static TimingsHandler::requestPrintTimings() : Promise<list<string>>` - asynchronously collects timing results from all threads and assembles them into a single report
+- The following API methods have been deprecated:
+  - `TimingsHandler::printTimings()` - this function cannot support async timings collection. Use `TimingsHandler::requestPrintTimings()` instead.
+  - `Timings::getAsyncTaskErrorTimings()` - internal method that is no longer needed
+- The following constants have been deprecated:
+  - `Timings::GROUP_BREAKDOWN` - no longer used
+
+### `pocketmine\utils`
+- The following API methods have been added:
+  - `public static Utils::getRandomFloat() : float` - returns a random float between 0 and 1. Drop-in replacement for `lcg_value()` in PHP 8.4.
+
+## Internals
+- Blocks are now always synced with the client during a right-click-block interaction. This clears mispredictions on the client in case the new `PlayerInteractEvent` flags were customized by plugins.
+- `VanillaBlocks` and `VanillaItems` now use reflection to lookup TypeId constants by registration name, instead of requiring TypeIds to be manually specified.
+  - While this is obviously a hack, it prevents incorrect constants from being used when adding new blocks, and guarantees that the names of constants in `BlockTypeIds` and `ItemTypeIds` will match their corresponding entries in `VanillaBlocks` and `VanillaItems` respectively.
+  - It also significantly improves readability of `VanillaBlocks` and `VanillaItems`, as well as eliminating ugly code like `WoodLikeBlockIdHelper`.
+  - In PM6, the team is exploring options to redesign `VanillaBlocks` and `VanillaItems` to eliminate the need for defining separate TypeIds entirely.
+- `ConsoleReader` now uses socket support in `proc_open()` to transmit IPC messages to the server process. Previously, a temporary socket server was used, which was unreliable in some conditions.
+- Event handler tests have been converted to PHPUnit tests by mocking `Server` and `Plugin` instances. Previously, these required integration tests for these dependencies.
+- Fixed various deprecation warnings in PHP 8.4.
+- `netresearch/jsonmapper` is now used at `5.0.0`. The PMMP fork of this library has been removed, as it is no longer needed.
+
+# 5.23.1
+Released 5th December 2024.
+
+## Fixes
+- Fixed signs not creating a tile when placed.
+
+## Internals
+- Improved blockstate consistency check to detect tiles disappearing during refactors.
+
+# 5.23.2
+Released 9th December 2024.
+
+## General
+- Updated translations for Russian and Korean.
+
+## Fixes
+- Fixed server build number.
+- Fixed some crashes being misreported as plugin-involved.
+
+## Internals
+- Removed legacy `build/make-release.php` script. This script is no longer used, as all releases should now follow the PR workflow.
+
+# 5.23.3
+Released 22nd January 2025.
+
+## Fixes
+- Fixed crashes with PHP internal stack frames being flagged as plugin crashes.
+- Fixed note block instrument sounds in 1.21.50.
+
+## Internals
+- Updated GitHub issue templates to use issue forms.

+# 5.24.0
+Released 22nd January 2025.
+
+This is a minor feature release, including new gameplay features, performance improvements, and minor API additions.
+
+**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.
+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.
+
+## Performance
+- PHP garbage collection is now managed by the server, instead of being automatically triggered by PHP.
+  - The mechanism for GC triggering is designed to mimic PHP's to avoid behavioural changes. Only the place it's triggered from should be significantly different.
+  - This change also avoids unnecessary GCs during object-heavy operations, such as encoding `CraftingDataPacket`. As such, performance during server join should see an improvement.
+  - Timings is now able to directly measure the impact of GC. Previously, GC would show up as random spikes under random timers, skewing timing results.
+- `ChunkCache` now uses `string` for completed caches directly instead of keeping them wrapped in `CompressBatchPromise`s. This reduces memory usage, improves performance, and reduces GC workload.
+
+## Configuration
+- The following settings have been removed from `pocketmine.yml` and will no longer have any effect:
+  - `memory.garbage-collection.collect-async-worker` (now always `true`)
+  - `memory.garbage-collection.low-memory-trigger` (now always `true`)
+  - `memory.max-chunks.trigger-chunk-collect` (now always `true`)
+  - `memory.world-caches.disable-chunk-cache` (now always `true`)
+  - `memory.world-caches.low-memory-trigger` (now always `true`)
+
+## Gameplay
+- Added the following new blocks:
+  - All types of pale oak wood, and leaves
+  - Resin
+  - Resin Bricks, Slabs, Stairs, and Walls
+  - Resin Clump
+  - Chiseled Resin Bricks
+- Some blocks have had their tool tier requirements adjusted to match latest Bedrock updates.
+- Added the following new items:
+  - Resin Brick
+  - Music Disc - Creator
+  - Music Disc - Creator (Music Box)
+  - Music Disc - Precipice
+  - Music Disc - Relic
+
+## API
+### General
+- Many places had their PHPDoc improved to address issues highlighted by PHPStan 2.x. This may cause new, previously unreported issues to be reported in plugins using PHPStan.
+
+### `pocketmine`
+- The following methods have been deprecated:
+  - `MemoryManager->canUseChunkCache()`
+  - `MemoryManager::dumpMemory()` - relocated to `MemoryDump` class
+
+### `pocketmine\item`
+- The following new enum cases have been added:
+  - `RecordType::DISK_CREATOR`
+  - `RecordType::DISK_CREATOR_MUSIC_BOX`
+  - `RecordType::DISK_PRECIPICE`
+  - `RecordType::DISK_RELIC`
+
+### `pocketmine\player`
+- The following new methods have been added:
+  - `public Player->getFlightSpeedMultiplier() : float` - a base multiplier for player's flight speed
+  - `public Player->setFlightSpeedMultiplier(float $flightSpeedMultiplier) : void` - sets the player's flight speed multiplier
+- The following new constants have been added:
+  - `Player::DEFAULT_FLIGHT_SPEED_MULTIPLIER`
+
+### `pocketmine\utils`
+- The following new methods have been added:
+  - `public static TextFormat::javaToBedrock(string $string) : string` - removes unsupported Java Edition format codes to prevent them being incorrectly displayed on Bedrock
+- The following methods have behavioural changes:
+  - `TextFormat::toHTML()` now converts `§m` to redstone red (instead of strikethrough), and `§n` to copper orange (instead of underline). This is because the codes previously used for `STRIKETHROUGH` and `UNDERLINE` conflict with the new material codes introduced by Minecraft Bedrock.
+  - `Terminal::toANSI()` now converts `§m` to redstone red (instead of strikethrough), and `§n` to copper orange (instead of underline), as above. However, underline and strikethrough can still be used on the terminal using `Terminal::$FORMAT_UNDERLINE` and `Terminal::$FORMAT_STRIKETHROUGH` respectively.
+- The following new constants have been added:
+  - `TextFormat::MATERIAL_QUARTZ`
+  - `TextFormat::MATERIAL_IRON`
+  - `TextFormat::MATERIAL_NETHERITE`
+  - `TextFormat::MATERIAL_REDSTONE`
+  - `TextFormat::MATERIAL_COPPER`
+  - `TextFormat::MATERIAL_GOLD`
+  - `TextFormat::MATERIAL_EMERALD`
+  - `TextFormat::MATERIAL_DIAMOND`
+  - `TextFormat::MATERIAL_LAPIS`
+  - `TextFormat::MATERIAL_AMETHYST`
+- The following constants have been deprecated:
+  - `TextFormat::STRIKETHROUGH`
+  - `TextFormat::UNDERLINE`
+- The following static properties have been added:
+  - `Terminal::$COLOR_MATERIAL_QUARTZ`
+  - `Terminal::$COLOR_MATERIAL_IRON`
+  - `Terminal::$COLOR_MATERIAL_NETHERITE`
+  - `Terminal::$COLOR_MATERIAL_REDSTONE`
+  - `Terminal::$COLOR_MATERIAL_COPPER`
+  - `Terminal::$COLOR_MATERIAL_GOLD`
+  - `Terminal::$COLOR_MATERIAL_EMERALD`
+  - `Terminal::$COLOR_MATERIAL_DIAMOND`
+  - `Terminal::$COLOR_MATERIAL_LAPIS`
+  - `Terminal::$COLOR_MATERIAL_AMETHYST`
+
+## Tools
+- Fixed some UI issues in `tools/convert-world.php`
+
+## Internals
+- Block cache in `World` is now size-limited. This prevents memory exhaustion when plugins call `getBlock()` many thousands of times with cache misses.
+- `RakLibServer` now disables PHP GC. As RakLib doesn't generate any unmanaged cycles, GC is just a waste of CPU time in this context.
+- `MemoryManager` now has the responsibility for triggering cycle GC. It's checked every tick, but GC won't take place unless the GC threshold is exceeded, similar to PHP.
+  - This mechanism could probably do with alterations to better suit PocketMine-MP, but it was chosen to mimic PHP's own GC to minimize behavioural changes for now.
+- `AsyncTask` now triggers cycle GC after `onRun()` completes. As with `MemoryManager`, this is based on a threshold designed to mimic PHP's own behaviour.
+- `FormatConverter` now performs world provider GC periodically. This is not needed with current active providers, but was found to be a problem while developing custom providers.
+- Various internal adjustments were made to avoid returning incorrectly-keyed arrays in the code. These changes shouldn't affect anything as the arrays should have been properly ordered anyway.
+- Many places that previously used `==` and `!=` have been updated to use strict variants. This kind of change needs to be done carefully to avoid breaking `int|float` comparisons.

+# 5.25.0
+Released 16th February 2025.
+
+This is a support release for Minecraft: Bedrock Edition 1.21.60. It also includes some minor API additions supporting new features in this version.
+
+**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.
+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.
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.21.60.
+- Removed support for earlier versions.
+
+## Documentation
+- Fixed the documentation of `Utils::getOS()`. It now refers to the `Utils::OS_*` constants instead of a list of hardcoded strings.
+
+## API
+### `pocketmine\inventory`
+This release allows plugins to decide which creative tab they want to add their new items to.
+It also allows creating new collapsible groups of items, and modifying or removing existing ones.
+
+- The following new methods have been added:
+  - `public CreativeInventory->getAllEntries() : list<CreativeInventoryEntry>` - returns an array of objects, each containing a creative item and information about its category and collapsible group (if applicable).
+  - `public CreativeInventory->getEntry(int $index) : ?CreativeInventoryEntry` - returns the creative item with the specified identifier, or `null` if not found
+- The following methods have signature changes:
+  - `CreativeInventory->add()` now accepts two additional optional parameters: `CreativeCategory $category, ?CreativeGroup $group`. If not specified, the item will be added to the Items tab without a group.
+- The following new classes have been added:
+  - `CreativeCategory` - enum of possible creative inventory categories (each has its own tab on the GUI)
+  - `CreativeGroup` - contains information about a collapsible group of creative items, including tooltip text and icon
+  - `CreativeInventoryEntry` - contains information about a creative inventory item, including its category and collapsible group (if applicable)
+
+## Internals
+- `CreativeContentPacket` is no longer fully cached due to the requirement for translation context during construction. The individual items are still cached (which is the most expensive part), but the packet itself is now constructed on demand, and group entries are constructed on the fly. This may affect performance, but this has not been investigated.
+- `BedrockDataFiles` now includes constants for folders at the top level of `BedrockData` as well as files.
+- The structure of creative data in `BedrockData` was changed to accommodate item category and grouping information. `creativeitems.json` has been replaced by `creative/*.json`, which contain information about item grouping and also segregates item lists per category.
+- New information was added to `required_item_list.json` in `BedrockData`, as the server is now required to send item component NBT data in some cases.
+
+# 5.25.1
+Released 26th February 2025.
+
+## Fixes
+- Fixed confusing exception message when a block-breaking tool has an efficiency value of zero.
+- Fixed incorrect facing of doors since 1.21.60 (resulted in mismatched AABBs between client & server, rendering glitches etc.)
+- Resource pack UUIDs are now validated on load. Previously, invalid UUIDs would be accepted, and potentially cause a server crash on player join.
+
+# 5.25.2
+Released 4th March 2025.
+
+## Fixes
+- Added limits to various `explode()` calls.

+# 5.26.0
+Released 22nd March 2025.
+
+This is a minor feature release focused on 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.
+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.
+
+## Performance
+- Significantly improved performance of entity movement. Load testing with item entities showed a 3x increase in the number of entities supported without lag.
+- Significantly improved performance of on-ground checks for player movement. This still needs further work, but optimisations implemented in this version should improve performance substantially.
+- Updated `pocketmine/nbt` dependency with performance improvements to `TAG_Compound` and `TAG_List` comparison. This should improve performance of inventory-related actions.
+- `InventoryTransaction` now avoids useless item clones when processing transactions, which should improve performance of inventory-related actions.
+
+## Dependencies
+- `pocketmine/bedrock-protocol` has been updated to `36.2.0`, which adds new functions to access some packet fields.
+- `pocketmine/nbt` has been updated to `1.1.0`, which improves performance when comparing NBT object trees.
+
+## Gameplay
+- Block breaking animation speed now takes into account the following: jumping, being in water, haste, mining fatigue
+
+## Tools
+- `blockstate-upgrade-schema-utils.php` now has a new `dump-table` command, which turns a `.bin` palette table file into human-readable text for debugging.
+
+## API
+### `pocketmine\block`
+- The following methods have been added:
+  - `public RuntimeBlockStateRegistry->hasStateId(int $stateId) : bool` - checks whether the given state ID is registered
+
+### `pocketmine\crafting`
+- The following methods have been deprecated:
+  - `CraftingManager::sort()` - this was implicitly internal anyway
+
+### `pocketmine\utils`
+- The following constants have been added:
+  - `TextFormat::MATERIAL_RESIN`
+- The following static properties have been added:
+  - `Terminal::$COLOR_MATERIAL_RESIN`
+
+### `pocketmine\data\bedrock\block`
+- `BlockStateToObjectDeserializer` now permits overriding **deserializers** for Bedrock IDs. This may be useful to implement custom state handling, or to implement missing block variants (such as snow cauldron).
+  - This was originally prohibited since 5.0.0. However, there is no technical reason to disallow overriding **deserializers**.
+  - Overriding **serializers** is still **not permitted**. Reusing type IDs doesn't make any sense and would break internal design contracts.
+  - If you want to make a custom version of a vanilla block, create a custom type ID for it, exactly as you would for a regular custom block.
+- The following methods have been added:
+  - `public BlockStateToObjectDeserializer->getDeserializerForId(string $id) : ?(\Closure(BlockStateReader) : Block)`
+
+### `pocketmine\data\bedrock\item`
+- `ItemDeserializer` now permits overriding **deserializers** for Bedrock IDs. As above, this may be useful to implement custom data handling, or to implement missing variants of existing items.
+  - This was originally prohibited since 5.0.0. However, there is no technical reason to disallow overriding **deserializers**.

+- The following methods have been added:
+  - `public ItemDeserializer->getDeserializerForId(string $id) : ?(\Closure(SavedItemData) : Item)`
+
+## Internals
+- `new $class` is now banned on new internals code by a PHPStan rule. Closures or factory objects should be used instead for greater flexibility and better static analysis.
+- `CraftingManager` now uses a more stable hash function for recipe output filtering.
+- `ChunkCache` now accepts `int $dimensionId` in the constructor. This may be useful for plugins which implement the nether.
+- `RuntimeBlockStateRegistry` now precomputes basic collision info about known states for fast paths.
+  - This permits specialization for common shapes like cubes and collisionless blocks, which allows skipping complex logic in entity movement calculation. This vastly improves performance.
+  - Any block whose class overrides `readStateFromWorld()` or `getModelPositionOffset()` will *not* be optimised.
+  - `Block->recalculateCollisionBoxes()` now has a hard requirement not to depend on anything other than available properties. It must not use `World` or its position.
+    - This change was problematic for `ChorusPlant`, which used nearby blocks to calculate its collision boxes.
+    - Blocks which need nearby blocks should override `readStateFromWorld()` and set dynamic state properties, similar to fences.
+    - This design flaw will be corrected with a major change to `Block` internals currently in planning for a future major version.
+- `Block->getCollisionBoxes()` may not be called at all during gameplay for blocks with shapes determined to be simple, like cubes and collisionless blocks.
+- `BlockStateToObjectDeserializer` now checks if the returned blockstate is registered in `RuntimeBlockStateRegistry` to promote earlier error detection (instead of crashing in random code paths).

+- Removed support for earlier versions.
+
+## Fixes
+- Fixed thread crashes sometimes not reporting proper cause information in crashdumps.
+- Fixed crash when a plugin replaced a player's held tool with a different tool with a damage exceeding the old tool's max damage during an action.

+
+## General
+- Significantly reduced log spam when unknown blocks, tiles and entities are found in saved worlds.
+- The file name structure for crashdumps has been changed to improve sorting order in file browsers.
+- Buffering is now skipped on the RakLib layer. In theory this could reduce player network latency by 10 ms (YMMV).
+
+## Gameplay
+### Blocks
+- Many blocks have had their hardness and blast resistance updated to match vanilla.
+- Implemented Respawn Anchor.
+- Melon Stem and Pumpkin Stem drop amounts should now match vanilla (using binomial distribution).
+
+## API
+## General
+- Verification of save registration has been added for blocks, entities and tiles. This is intended to make it easier to find mistakes when registering custom things, which previously would produce obscure core crashes.
+
+### `pocketmine\event\block`
+- The following classes have been added:
+  - `BlockPreExplodeEvent` - called before a block tries to explode
+  - `BlockExplodeEvent` - called when after a block's explosion calculation has been done, but before any changes are applied
+
+### `pocketmine\event\entity`
+- The following classes have been added:
+  - `EntityExtinguishEvent` - called when a burning entity is extinguished by water or other sources
+  - `EntityFrostWalkerEvent` - called every tick upon which an entity wearing Frost Walker boots moves; this can be used to customise or cancel the behaviour of the Frost Walker enchantment
+
+### `pocketmine\event\player`
+- The following classes have been added:
+  - `PlayerRespawnAnchorUseEvent` - called when a player interacts with a charged respawn anchor
+
+### `pocketmine\entity`
+- The following methods have been added:
+  - `public Entity->getStepHeight() : float`
+  - `public Entity->setStepHeight(float $stepHeight) : void`
+
+### `pocketmine\world\generator`
+- Generator execution has been decoupled from `PopulationTask` and async tasks in general. The following classes have been added:
+  - `executor\GeneratorExecutor`
+  - `executor\SyncGeneratorExecutor` - runs a generator on the main thread (used for flat world generation, which doesn't need threads)
+  - `executor\AsyncGeneratorExecutor` - runs a generator inside an async task, as before
+  - `PopulationUtils` - contains population business logic previously baked into `PopulationTask` - this permits the reuse of that logic outside async tasks
+- The following methods have signature changes:
+  - `GeneratorManager->addGenerator()` now accepts an optional `bool $fast` parameter, defaulting to `false`; setting this to `true` will cause your generator to run on the main thread
+- The following methods have been added:
+  - `public GeneratorManagerEntry->isFast() : bool` - returns whether this generator should run on the main thread
+- `PopulationTask` has been marked as `@internal`. In the next major version, it will move to the `generator\executor` namespace; however, for now it stays put because plugins currently have no other way to regenerate chunks.
+
+## Internals
+- World data version numbers have been consolidated in `pocketmine\data\bedrock\WorldDataVersions`. This removes the need to modify several different files to support new world versions, and reduces the chances of things getting missed.
+- Block hardness and blast resistance is now unit-tested against `block_properties_table.json` in `BedrockData`. This file comes from vanilla BDS, so we can use it to verify compliance.
+- Protocol-layer "server auth block breaking" has been enabled. Functionally, this is no different from the previous system, it just works differently on the network layer.
+- Various internal classes in the `pocketmine\world\generator` namespace have been moved to the `generator\executor` namespace.
+- Removed `World->registerGenerator()` and `World->unregisterGenerator()`.
+- Removed redundant calls to `curl_close()` (obsolete since PHP 8.0).
+
+# 5.30.1
+Released 23rd June 2025.
+
+## Fixes
+- Fixed accidental break of backwards compatibility in `EntityExplodeEvent` introduced in the previous release.
+- Fixed placement of player holding block when exploding respawn anchor.
+- Updated BedrockProtocol to fix incorrect encoding of `ServerScriptDebugDrawerPacket`.
+- Disabled client-side locator bar, allowing plugins to write their own implementations.

+## Performance
+- Worlds now remember when a chunk isn't generated. This reduces world I/O during world generation.
+- `BlockObjectToStateSerializer` now creates fewer objects in certain cases.
+
+## Gameplay
+- The following blocks have been added and/or are now properly supported:
+  - Hanging signs
+  - Illager banners
+
+## Tools
+- `generate-bedrock-data-from-packets.php` now represents items as strings directly when only an ID is present. This significantly improves readability in `BedrockData` and reduces file sizes.
+
+## API
+### `pocketmine\block`
+- Added (and implemented) interfaces for many common block properties, to allow `instanceof` to be used:
+  - `Ageable`: for blocks with age, such as crops
+  - `AnyFacing`: for blocks which can face up, down, and horizontal directions (not the same as `HorizontalFacing`!)
+  - `Colored`: for blocks with 16 `DyeColor` variants
+  - `CoralMaterial`: for coral blocks, provides access to coral type and dead/alive
+  - `HorizontalFacing`: for blocks which can **only** face horizontal directions (not the same as `AnyFacing`!)
+  - `Lightable`: for light-source blocks which can be turned on and off, e.g. redstone lamp
+  - `MultiAnyFacing`: for blocks which can appear in multiple faces of the same block (including up, down, and horizontal faces), e.g. glow lichen
+  - `PillarRotation`: for blocks which can be oriented on an axis, e.g. logs
+  - `PoweredByRedstone`: for blocks which receive power from a redstone component, e.g. redstone lamp
+  - `SignLikeRotation`: for blocks which can be rotated 16 ways, e.g. signs, banners
+  - `WoodMaterial`: for blocks made from wood
+  - These interfaces have been implemented on many blocks. For the sake of brevity, they are not listed here, but you can expect to see them wherever the corresponding traits were used.
+- The following classes have been added:
+  - `BaseOminousBanner`
+  - `CeilingCenterHangingSign` - both chains connected to the same point on the block above, can face 16 directions
+  - `CeilingEdgesHangingSign` - each chain connected to separate edges of the block above, can face 4 directions
+  - `OminousFloorBanner` - floor version of illager banner, can face 16 directions
+  - `OminousWallBanner` - wall version of illager banner, can face 4 directions
+  - `WallHangingSign` - hangs from a horizontal beam, can face 4 directions
+- The following API methods have been added:
+  - `public ChiseledBookshelf->setSlots(list<ChiseledBookshelfSlot> $slots) : $this`
+  - `public static VanillaBlocks` methods:
+    - `ACACIA_CEILING_CENTER_HANGING_SIGN() : CeilingCenterHangingSign`
+    - `ACACIA_CEILING_EDGES_HANGING_SIGN() : CeilingEdgesHangingSign`
+    - `ACACIA_WALL_HANGING_SIGN() : WallHangingSign`
+    - `BIRCH_CEILING_CENTER_HANGING_SIGN() : CeilingCenterHangingSign`
+    - `BIRCH_CEILING_EDGES_HANGING_SIGN() : CeilingEdgesHangingSign`
+    - `BIRCH_WALL_HANGING_SIGN() : WallHangingSign`
+    - `CHERRY_CEILING_CENTER_HANGING_SIGN() : CeilingCenterHangingSign`

+### `pocketmine\data\bedrock\block\convert`
+- A new system for symmetric block serializers and deserializers has been introduced.
+  - This allows registering both a serializer and a deserializer with the same code, meaning way less code
+  - It also eliminates information duplication and potential inconsistencies, improving maintainability.
+  - A proper way to deal with flattened IDs (e.g. color blocks) has been introduced which _doesn't_ require hardcoding a giant mess of IDs
+  - This symmetric system covers 99% of blocks which have a 1:1 association between PM and vanilla blocks, or 1:N where IDs are flattened
+  - However, there are still some special cases which require registering separate serializers and deserializers (usually in cases where the PM implementation deviates from Mojang where Mojang's implementation sucks, such as hanging signs or big dripleaf).
+  - No backwards compatibility breaks are expected as a result of this change. However, it's recommended to migrate old code to this new system for maintainability.
+  - The following new classes have been added:
+    - `BlockSerializerDeserializerRegistrar` - handles unified registration of block serializers and deserializers, based on a provided block model
+    - `FlattenedIdModel` - represents a block with some properties baked into its Minecraft ID, e.g. coral or color blocks
+    - `Model` - represents a regular block with all properties in its `states` NBT
+    - `property\BoolFromStringProperty<TBlock>` - property mapping a bool value from a string NBT state
+    - `property\BoolProperty<TBlock>`
+    - `property\CommonProperties` - singleton containing commonly-used block property definitions and groups, e.g. facing, stair properties
+    - `property\EnumFromRawStateMap<TEnum, TRaw>` - maps a raw NBT value to a PHP `enum` and vice versa
+    - `property\IntFromRawStateMap<TRaw>` - maps a raw NBT value to PM integer constants and vice versa
+    - `property\IntProperty<TBlock>` - an integer range property with a min, max, and optional offset
+    - `property\Property<TBlock>` - interface implemented by all property definitions accepted by a `Model` or `FlattenedIdModel`
+    - `property\StateMap<TValue, TRaw>` - interface implemented by classes accepted by mapping properties, e.g. `BoolFromStringProperty`
+    - `property\StringProperty<TBlock>` - interface implemented by properties whose raw outputs are strings - these can be used as ID components in `FlattenedIdModel`
+    - `property\ValueFromIntProperty<TBlock, TValue>` - property mapping a generic PM value from an int NBT state
+    - `property\ValueFromStringProperty<TBlock, TValue>` - same as above, but for a string NBT state
+    - `property\ValueSetFromIntProperty<TBlock, TOption>` - a property mapping an `int[]` or `enum[]` from a set of flags in NBT states
+    - `property\ValueMappings` - singleton containing commonly-needed `StateMap`s
+  - The following classes have been deprecated:
+    - `BlockStateDeserializerHelper`
+    - `BlockStateSerializerHelper`
+  - The following methods have been deprecated:
+    - All methods for decoding mapped property types in `BlockStateReader`, e.g. `readFacingDirection()`
+    - All methods for encoding mapped property types in `BlockStateWriter`, e.g. `writeFacingDirection()`
+    - All specific blocktype mapping functions in `BlockStateToObjectDeserializer`, e.g. `mapStairs()`
+    - All specific blocktype mapping functions in `BlockObjectToStateSerializer`, e.g. `mapStairs()`
+
+### `pocketmine\item`
+- The following hooks have been added:
+  - `public Item->getPlacementTransaction(Block $blockReplace, Block $blockClicked, int $face, Vector3 $clickVector, ?Player $player = null) : ?BlockTransaction` - allows more complex logic for itemblocks to place blocks, without duplicating their placement conditions (used for hanging signs)
+
+### `pocketmine\world`
+- `World->setChunk()` now verifies that blockstate IDs in the provided chunk are all registered in `RuntimeBlockStateRegistry`. This should provide earlier detection for custom block registration errors by plugins.
+
+## Internals
+- `BlockStateUpgrader` is now almost entirely independent from `BlockStateData`. It's anticipated that the upgrader library will be separable from the core in the future.
+- `Block->readStateFromWorld()` is now triggered on chunk load for any position containing a tile. This should allow more effective updating of blocks with properties in their tiles.
