How to update my Minecraft?

When I log into my mine craft account, it says "ready to play version 1.7.10", but when I enter the game and go into creative mode to check if the new blocks are there, diorite and other blocks aren't there.

Oh! That is easy! There are three simple steps.

1. Click the uninstall button.
2. Apply for Everquest Next (Landmark) beta.
3. Wait.

The new features aren't in 1.7.10 (1.7.10 is mostly fixes to Minecraft Realms), to get the new features you have to enable experimental snapshots. To do that just go into your minecraft launcher and in the bottom left it says your profile click 'edit' there should be an option to enable snapshots.

Thank you so much Zach
