Step Up – Increases your step height so you can step up a full block.

Reach – Increases your reach distance.

Repairing – Repairs your armor and held item.

Flight – Lets you fly like in creative mode.

Random Teleport – Teleports you to a nearby location.

Surface Teleport – Teleports you to the top surface block.

Spawn Teleport – Teleports you to your spawn point if you stand still with it for 10 seconds.

Love – Causes breedable entities to breed with eachother.

Other:

Curse – Gives you one random bad potion effect.

Cure – Clears all bad potion effects from you.

Dispel – Clears all good potion effects from you.

Inversion – Inverts all potion effects on you (like regeneration -> wither, strength -> weakness, etc.).

Potion Sickness – Disabled by default. Has a low chance of giving you a random bad potion effect.

It also changes the way a few vanilla potions work:

Blindness – Now the fog comes closer per level (making you more blind), and it also affects mobs, so they won’t attack you unless you are close to them.

Jump Boost – You can control how high you jump by holding down the space bar, so you can jump up one block instead of shooting into the air.

There are also a few new attributes (that can be applied to armor and tools as well):
