5.11.0

• New items and entities now show their names as translatable components instead of string text and can be changed via resource packs
  • Entities use vb.entity.<type>, e.g. vb.entity.sulfur_cube, which falls back to 26.2 Sulfur Cube as before. entitynames has been removed from mapping files
  • Items use vb.item.<type>, e.g. vb.item.sulfur, which falls back to 26.2 Sulfur as before. itemnames has been removed from mapping files
  • Custom model data for new items has been moved to custom_model_data in the mapping files and starts at 0 for the first 1.13 item, going upwards across every protocol (currently ending at 937). 1.21.4+ clients have their original item identifier added to the custom_model_data string list, and all client versions have the custom model data from the mapping files added (either to the new float list or the old single-int tag)
• On 1.21.5+ servers, handling of items sent by the client now mostly skips from 1.20.4 to 1.21.5 to avoid heavy item reading and transformation code
  • If your server is on a version between 1.20.5 and 1.21.4, it is highly recommended you update to 1.21.5 or higher
• Fixed multi-line text displays in 1.19.4->1.19.3
• Fixed disconnects when using new environment attributes in custom dimensions
• Fixed invisible beds in 26.2->26.1 (by booky10)
