Todays snapshot brings in a complete rewrite of how world generation works behind the scenes, so that we can do some really cool things with it in the future & speed it up dramatically. It may be quite unstable in this first snapshot though, so as always: do not open worlds you care about in a snapshot without having a backup first. We can almost guarantee that any world opened in this snapshot will not work in the full 1.13 release.

Changes in 18w06a

Re-added /enchant command

command Added a recipe book for the furnace

Rewrote the world generation system

Added command suggestions for entity selectors

Allow whitespaces in entity selectors & blockstate arguments

Added new item & block tags

Furnace recipe book

Now there's a recipe book for the furnace! Exactly like the existing crafting recipe books, you can unlock recipes as you play through the game and they will automatically appear in your recipe book for smelting. Mapmakers can customize the recipes with data packs, which allows them to add or completely change furnace recipes. "Fuel", the items that can be burned in a furnace, is not included in this and is still somewhat hardcoded currently.

World generation

We've spent the last few years (yes, years) rewriting the world generator completely from the ground up, and this snapshot finally has the first version that we have some kind of confidence in. It may not be much faster at first, but that's because we're playing it safe and want to just achieve "it works" before "it's fast". It might still be unstable, too, so watch out for that. It's the very first snapshot with it in, after all!

Customized Worlds

... don't work in this snapshot. Sorry. We have plans to re-add them in a much more extendible way, but unfortunately we were not able to have that ready yet. You will be unable to open any world of type "customized" in this snapshot, it will tell you to revert to an old version to play in those worlds.

/enchant vs /modifyitem

It's back how it was. We have shelved the /modifyitem idea that was supposed to replace /enchant and we will look into that again in a future update.
