13.0.0 for Minecraft Bedrock 1.19.30

Changes since 12.x.x

Protocol changes

New packets

• GameTestRequestPacket
• GameTestResultsPacket
• RequestNetworkSettingsPacket - this is now the first packet in a session, instead of LoginPacket
• ServerStatsPacket

Removed packets

• AdventureSettingsPacket

Packet changes

• NetworkSettingsPacket has new fields int $compressionAlgorithm, bool $enableClientThrottling, int $clientThrottleThreshold, float $clientThrottleScalar
• StructureBlockUpdatePacket has a new field bool $waterlogged
• TextPacket has a new type TYPE_JSON_ANNOUNCEMENT

New enums

• CompressionType - used by NetworkSettingsPacket

Other changes

• RecipeIngredient now accepts an ItemDescriptor instead of ID+meta. This enables more features like selecting items based on tags, Molang code, or other conditions. The types of descriptors currently supported are:
  • IntIdMetaItemDescriptor - this is used by all current vanilla recipes and is essentially the same as what we had to begin with
  • MolangItemDescriptor - allows selecting compatible items based on a Molang code predicate
  • StringIdMetaItemDescriptor - same as IntIdMetaItemDescriptor, but uses string IDs and doesn't allow negative meta values (?)
  • TagItemDescriptor - allows selecting compatible items based on their type tags, like in Java (see the wiki)
