New snapshot tomorrow, including biome changes. I know they wouldn't make biome changes unless they think we'd like what they are doing, because every time generation changed in the past people got angry. At the very least, Jeb showed that dark spots occur much less... Well, last time he did that, he found out it lagged everyone to calculate where to place late on generation, so we'll see if that was corrected. If we still hate whatever they are doing, we can yell at them...

And the options menu is now more dynamic. It is now a scrolling feature, which also gives each option more room. Besides that, it'd probably be easier for modders to add options for their mods to the game. Instead of adding buttons which lead to menus which you need to press more buttons to go deeper or even create an entire GUI for it, they can just add another scrolling options menu based off the vanilla code.
Edit: Jeb's lighting example:
