Changes

This section is missing information about: visual differences in the tooltip background compared to the previous snapshot.

Please expand the section to include this information. Further details may exist on the talk page.

Items

Ender pearl

Ender Pearls now ensure that the chunk they are in or travel into is always loaded and ticking.
They also load chunks when crossing to a new dimension, so that they can always continue to travel.
This ensures that Ender Pearls can always land, and makes cross dimensional ender pearl traveling more predictable.
Ender Pearls now unload when a player logs out, and reappear whenever that player logs back in, similar to how mounts currently behave
Each Ender Pearl creates a ticket for chunk loading any time it moves into a new chunk, and also periodically every 10 seconds.
