Do we need to make sure to state ->default(null)->nullable() here so we don't revert that state?

[Godmartinz]

I dont think so, is_nullable is still set to true/yes in the database.

The initial migration set that up correctly?

[snipe]

Yeah, just wasn't sure whether ->change() changed all of the characteristics or just the ones you specify. If your migration looks good, I'm in.
