Magma Cream

Magma Cream was first added in the 1.9 Pre-Release 2. It can be crafted with Blaze Powder and a Slimeball. They have a use in 1.9 Pre-Release 3, for potions and are mostly used for fire resistance attributes.

As of 1.9 Pre-Release 3, while fire resistance is in effect you can swim in lava with no damage. However, touching a block while immersed in lava causes insta-death.
