18w30a is the first snapshot released for Java Edition 1.13.1, which adds a search bar in the world list and a few other things, and fixes many bugs.[1]

Additions[]

World list
  • Added a search bar in the world list.
Blocks
  • Re-added punch-to-explode TNT using the unstable state (instead of the explode state in 1.12)
Debug screen
  • Added Ctrl + F3 + C to force a JVM crash, instead of a regular crash. However, with some keyboards it only triggers with right control.[2]
