Minecraft 23w18a
A new snapshot adds telemetry tweaks and fixes an 11 year old bug. See the changelog.
Sniffer
The sniffer’s height decreases by 0.4 blocks (from 1.75 to 1.35 blocks) when digging. The sniffer’s eye height decreases from 1.14 to 0.81 blocks.
Supporting Block
To fix MC-1133, the game now calculates which block the player is standing on (the “supporting block”) differently.
The game finds all blocks the collide with the entity’s hitbox extended 0.000001 blocks downward. Out of those blocks, the block whose center has the shortest distance to the entity’s center is the supporting block. If two blocks have the same distance, then the block with the higher Y coordinate wins. If the Y coordinates are the same, then the block with the higher Z coordinate wins, then the block with the higher X coordinate wins.
Structures
Desert pyramids no longer generate sand outside its bounding box.
Fixed a bug where strongholds would incorrectly generate a torch instead of a wall torch.
Telemetry
Launcher Name
The official launcher sets the system property to minecraft-launcher. Launching the game through an external launcher or as a server leaves the system property blank.
Advancement Made
The advancement_made optional telemetry event is sent when the player completes an advancement or unlocks a recipe.
Understanding the context behind receiving an advancement can help us better understand and improve the progression of the game

Game Load Times
The game_load_times optional telemetry event is sent when the game completely finishes loading.
This event can help us figure out where improvements to startup performance are needed by measuring execution times of the startup phases
