Tommaso asked the community that if he doesn't add the commands for 0.9, instead he will add a button used to switch gamemodes

Ok, let’s say in 0.9 there are no commands, but there’s a button to switch game mode. Deal? :P

@iTrueMU the plan is to have it for 1.0 :)

MCPE just became something like three times faster after I found & fixed some not too smart code about work scheduling :D
— Tommaso Checchi (@_tomcc) April 9, 2014

Tommaso said on Twitter that MCPE is now 3x faster than 0.8.1. We're not sure if this only applies to multi-core devices or also applies to single-core devices

As you can see here the grass transitions correspondingly to its biome.

@Pokemonster3241 I don't know if I have a complete list right now. A lot of it is still in the works. (50+ biomes and variations) :)
— Johan Bernhardsson (@jbernhardsson) April 1, 2014

@Pokemonster3241 Not entirely sure yet, I hope to add it to the 0.9.x/1.0.0 release.

Skins will be added to the sub-updates of 0.9.0 or in the 1.0.0 update.

@AsheicS May, I hope. :)
— Johan Bernhardsson (@jbernhardsson) April 1, 2014

Johan told us that the 0.9.0 update will release on May. Specifically late-May to early-June

New world generator in action. A couple of more days and the new biomes should work. :) pic.twitter.com/HpUQXlfs2C

After a user noticed that PE 3D clouds only have two shades, he asked Tommaso if he could fix it, Tommaso did

@MisterWhite_548 uhm uhm, interesting detail! Yeah, I'll add it to the TODO at least :)
