Java Edition 1.12

1.12 is an upcoming major update with no set release date.

Initially mentioned by Jeb at Minecon 2016 during the "Casual Chat with Jens" panel, saying that they already have ideas for a theme. On December 29, 2016, Jeb confirmed that he had started working on 1.12 features, and that they now have a theme.

Jeb said that there would not be a snapshot the first week of February, and showcased a new block that solidifies in water instead.
