And the new ones:
Warpling
Warplings are humans who have either spent ample time in the Maelstrom or can trace their lineage back to its native inhabitants, such as proteans. This connection with the Plane of Chaos can manifest in any number of ways and even shift over time. The colouration of their hair, skin and eyes can be of any hue and can sometimes change during emotional outbursts or through profound experiences. Their forms can also feature scales, feathers, ridges, warped appendages and even vestigial horns, wings, fins, spikes, fangs or tentacles. Some may even excrete a fine mist, glossy ichor or ripples of chaotic energy across their skin.

Fated
The Fated are humans with a fabricated existence. Some are the rare descendants of axiomites who study the laws of procreation, but most are conceived specifically to either repay an ancestor's divine debt or fulfil a specific role in a lawful deity's divine plans. While mostly human in appearance, the Fated tend to exhibit a single, obvious trait of axiomic influence. Examples include mechanical-looking joints or appendages, visible veins and blood vessels in straight and right-angled patterns, unusually symmetrical facial features and expressions or the appearance of glowing, crystalline symbols on their skin during moments of intense concentration, physical exertion or the events leading up to their intended destiny.
Racial Traits
* +2 to any one stat.
* Normal Speed: Fated have a base speed of 30 feet.
* Darkvision: Fated can see in the dark up to 60 feet.

* Fated Sorcery: Fated Sorcerers must take the Destined bloodline.
* Languages: Fated begin play speaking Common and Celestial. Fated with high Intelligence scores can choose any of the following bonus languages: Aquan, Auran, Draconic, Dwarven, Elven, Gnome, Halfing, Ignan and Terran.
Alternative Favoured Class Bonuses
Alchemist -- 1/4 bonus discovery
Cavalier -- Add +1/4 to the cavalier's banner bonus
Paladin -- +1 to Concentration checks when casting Paladin spells
Monk -- Add +1/4 to the Monk's Ki Pool
Inquisitor -- Add 1/2 to Sense Motive checks and Knowledge checks to identify monsters
Oracle -- Treat the oracle's level as +1/2 higher for the purpose of determining the effects of the oracle's curse ability.
Of course there's room for alternative racial traits, but we usually leave these up to the imagination of the players and their GM. Some examples include replacing the spell-like ability with a 50' Glide speed (move 5' per 1' fall), a secondary natural attack (usually bite, gore or tail slap) or a +2 racial bonus to knowledge, perform or craft checks. In some cases, I've even replaced the Tiefling's bonus to bluff with intimidate for the more 'fiendish' looking characters.
When it comes to outsiders, anything goes. ;)
These are just rough drafts that might change over time, but they are at least playable and (mostly) balanced in their current state. Enjoy!
