Additions

The Power of Books
- Read the power signal of a Minecraft:Chiseled Bookshelf using a Minecraft:Comparator.

No longer requires a smithing template to be in the template slot before placing an item into the other slots.

All fields in placed_block, item_used_on_block, and allay_drop_item_on_block advancement triggers have been collapsed to a single location field.
- New location is similar to the player field - it's a list of loot conditions/predicates.
- All conditions in this list must match for a trigger to run.
Conditions are evaluated in a new loot context called advancement_location. It has access to:
- Player as this entity.
- Position of the placed/interacted block.
- Block state of the placed/interacted block.
- Held/used item as "tool".
Migration guide:
- Contents of old location field should be migrated to a location_check condition.
- Contents of item field should be migrated to a match_tool condition.
- Contents of block and state fields should be migrated to a block_state_property condition.
Advancement fields now have a new boolean field called sends_telemetry_event.

Version is now 15, accounting for predicate/loot table and advancement changes.

Condition alternative has been renamed to any_of.
Added new condition all_of that passes only when all sub-conditions pass.
- It has the same syntax as any_of.

Walking on a block now always plays a step sound.
- It was previously not the case if the player was walking along the edge of a block with air or fluid beside it.
Walking on the ocean floor produces a step sound for the block the player is walking on, but at a lower volume and pitch.

Added new property: launcher_name.
- A new global property sent with every event.
- This is set based on the minecraft.launcher.brand system property.
- This helps developers troubleshoot game launch related bugs more effectively, as they are able to see whether the issue originated in the Minecraft launcher or a third-party program.
Added new property realms_map_content to event world_loaded.
- When loading into a Realms Map Content world (Minigame), the world_loaded event receives the name of that map.
- This is to help developers understand how Java Realms users interact with Java Realms adventure or minimap content.
Added new optional event advancement_made.
- This event is triggered when a player completes an advancement.
- This allows developers to see the advancement ID and the time when the advancement was completed, and helps them as a studio understand player progress and limits, which informs their game design.
Added new optional event game_load_times.
- An event that is triggered when the game client is loaded, and includes the time it took for the client to load.
- This is so that developers can work on improving and reducing the time it takes to load the game client.
