Johan Bernhardsson replied to a Reddit comment confirming Saddles and riding on pigs

@Lighticegamer Not sure, but I think boats will be in 0.9
— Jens Bergensten (@jeb_) December 27, 2013

Boats have been confirmed for 0.9, as stated by Jens Bergensten himself

We all know that most Minecraft news comes from the developer’s Twitter accounts, but what about other sites? Believe it or not, Johan from Mojang has a Reddit account that he uses to respond to users on Pocket Edition-related subreddits. While browsing his comment history, I found something interesting that I have not seen elsewhere. On Reddit, he replied to a user asking if 0.9.0 would be out by the end of 2013, he said “Nope, planned for Q1 next year.”

In other words, Johan said that Minecraft Pocket Edition 0.9.0 will be released in the first quarter of next year. Technically speaking, the first tax quarter of 2014 (which is what Q1 means) starts on January 1st and ends on March 31st.

Yey, MCPE 0.8.1 has been submitted. Besides multiplayer/realms fixes, it should also fix keyboard issues on Android. :)

Here is a gameplay of 0.8 by JackFrostMiner

New creative inventory! :) pic.twitter.com/MoAD03Zqym
— Johan Bernhardsson (@jbernhardsson) November 18, 2013

This is the new creative inventory to be added in 0.8

-In the pic, Johan added the tall grass and ferns which he didn't mention

New feature for 0.8.0, beets! Can be turned into dye and soup. :) pic.twitter.com/BsF743yuMG
— Johan Bernhardsson (@jbernhardsson) November 14, 2013

Beets have been added into the game but it is unclear whether it is for 0.8 or 0.9

So if u went to Minecon and didnt see 4JStudios, that was probably cause they didnt go, this is the reason why. (Below) |  |  |

Johan just tweeted some exclusive stuff that will be on pocket edition, this is what he said "New feature for 0.8.0, beets! Can be turned into dye and soup. :)" i dont know exactly what "beets" are but you can turn them into dye and soup, the soup looks disgusting to be honest.

Tommaso added an unknown feature that may be faster chunk loading or higher block limit

I like this thing whatever it is, let's just ship it pic.twitter.com/QKzKReIV8t
— Tommaso Checchi (@_tomcc) November 12, 2013

Jens Bergensten, one of the main developers for Minecraft, posted a pic on Instagram a picture that states he added secret stuff to Minecraft - Pocket Edition, which may be Spider Eyes

The pic is from the PC version but the things he added are in the pic.

It is unconfirmed whether he added the stuff to 0.8 or 0.9

For 0.8:
1. Breeding has been confirmed
2. Jack-o-lanterns have been added

For 0.9
1. Endermen will be added
2. New biomes at the edge of non-infinite worlds
