MCPE developer Tommaso Checchi has tweeted about a new Pocket Edition only feature coming in 0.7.4- the ability to force explode those creepers. I suppose this could work as free TNT…
0.7.4 will also have the tool breaking sound found in PC. Not only that, but the MCPE devs are hoping to port the PC terrain generation for PE, which could mean we get new biomes and possibly even villages and temples! But we can’t expect that for a while.
And in 0.8.0 when can expect flint and steel in creative!
Edit: Not just that, but direct IP connect has been added, which is replacing PocketMine Realms.
