Here's my (incomplete) list. Minus the psionic supplement, which it it's own document.

Wild Shape follows the new Polymorph spell description (see below), however there is no limit to the natural armor or ability scores the druid can take on through wildshape. The druid can also utilize natural poisons of any form she takes, as parts of her body that separate do not revert to their natural form. The druid can only take one form per use of wildshape.
The druid may choose to have a larger number of weaker animal companions. Their total HD can not exceed the HD a single companion would be allowed.
Fighter: No changes.

Rogue: Rogues receive a virtual Trapfinding feat at level 1 for free, rather than a class ability.
Rogues can choose from the following list of added special abilities:
Lightning strike (ex): Whenever an opponent you threaten is denied their Dexterity bonus against you, you may make an immediate attack of opportunity against them. You may only use this once per round. (Note that this extra attack of opportunity is not a sneak attack when you feint an opponent, since the feint bonus only applies to a single attack. In such a situation you feint, make an attack (no Dex) and then take your free attack (Dex bonus applies)).
Skilled slight of hand (ex): You may pick pocket any object you can hold in one hand easily (your size or smaller), with no penalty due to the size of the object. You could draw a fighters sword before he could, in some cases, and usually without him noticing...
Faceless (ex): In an urban environment with ten or more people about you can hide in plain sight by simply blending into the crowd, even if being watched. People have a hard time remembering your face, so any disguise penalties you may incur through someone?s familiarity with you (such as having wanted posters plastered across the city, or having run in with a certain town guard before) are negated.
Lightning feint (ex): You may make a feint as a free action once per round.
Ambush (ex): During a surprise round you may make a single extra attack as a free action.
Thorn in their side (ex): If others are flanking a target you gain the benefits of flanking against that target, even when you are not yourself flanking. This only applies to melee attacks.
Sorcerer: Sorcerers do not use material components, but instead use foci for all their spells. If a spell has a material component with a GP cast listed the sorcerer expends 1/25th of the cost in XP to cast the spell (no focus needed). Material components that are linked to the spells function, such as the gem for trap the soul, are required as normal.
Sorcerers add Use Magic Devices and Intimidate to their class skill list, but do not have knowledge (arcana). A sorcerer receives one rank of spellcraft per level for free (4 instead for 1st level, single-classed sorcerers).
Wizard: Specialist wizards choose a number of schools worth at least as many points at their main school to ban per the following table:
1-Divination
2-Enchantment, Necromancy, Illusion, Abjuration
3-Conjuration, Transmutation, Evocation
Multi-class: The multiclass character experience rules are not used. Instead if your highest class level is a favored class for your race, you receive a 5% experience bonus.
Skills
Craft(Alchemy): This skill may be used by anyone.
Equipment
Revised size rules for weapons are not used. Instead use the original 3E weapon size rules.
Combat
Death?s Door: You do not die until you reach -10-HD HP. So a 4th level wizard, for instance, is not killed until he is brought to -14 hit points.
Feats
The following feats are not used: Greater Spell Focus
CHANGED FEATS
Meta-magic: You can stack the same meta-magic feat onto a spell more than once. Multiplicative benefits are of course handled additively (a triple extend gives you a spell with 4x the original duration).

Transmutation
Level: Sor/Wiz 4, Rng 4

Duration: 1 hour/level
You change your form to that of another creature. The new form can range in size from Diminutive to one size category larger than your normal form. It can have no more Hit Dice than you have, and in any case the assumed form cannot have more than 15 Hit Dice. You cannot change into a construct, elemental, outsider, or undead unless you are already are that type. You can continue to change forms for the duration as, each change is a full round action. You can only make up to one change of forms per level (15 maximum), after words the spell ends. Reverting to your normal form counts as a change.
Upon changing, you regain lost hit points as if having rested for a day (though this healing does not restore temporary ability damage and provide other benefits of resting for a day; subsequent changes do not heal you further). If slain, you revert to your original form, though you remain dead. You acquire the physical and natural abilities of the new form: natural size, physical ability scores (average Strength, Dexterity, and Constitution for your new form?s kind, up to a maximum of 20 in any single score), natural armor (maximum of 4), natural weapons (such as claws or bite, but not petrification, breath weapons, energy drain, energy effects, or the like), and similar gross physical qualities (presence or absence of wings, number of extremities, and so forth). You gain the natural attack routines of your new form. Natural abilities also include mundane movement capabilities, such as walking, swimming, burrowing, and flight with wings; darkvison, low-light vision, scent ability, most forms of blindsense & blindsight and most racial bonus feats (with the exception of psionic or other feats that are not extraordinary in nature).
You do not acquire other extraordinary, supernatural, or spell-like abilities of your new form. You cannot change into a variant form of a creature, such as a half-dragon ogre. Incorporeal or gaseous forms cannot be assumed. You retain your Intelligence, Wisdom, and Charisma scores, level and class, hit points (despite any change to your Constitution score), alignment, base attack bonus, and base save bonuses. (New Strength, Dexterity, and Constitution scores may affect final attack and save bonuses.) You retain your extraordinary abilities, spells, and spell-like abilities, but not your supernatural abilities (if any). You can manifest psionic powers or cast spells for which you have components, but you need a humanlike voice for verbal components and humanlike hands for somatic components.
If your new form is roughly similar to your original form (humanoid, quadruped et cetera), your equipment changes to match the new form and retains its properties. Otherwise, it melds into the new form and becomes nonfunctional, except that any magic or psionic items you wear that provide enhancement bonuses to mental ability scores (such as a periapt of wisdom) continue to provide their benefit. Melded material components and focuses cannot be used to cast spells without the natural spell feat. Any part of the body or piece of equipment that is separated from the whole reverts to its original form, thus any poison based attack from your new form does not function.
You choose your form?s physical qualities (such as hair color, height, and gender), but they must fall within the normal ranges for the form. You are effectively disguised as an average member of the new form?s race. If you use this power to create a disguise, you get a +15 bonus on your Disguise check.
Speical: A druid uses the same rules as this spell for wildshape with some exceptions. They may only take one form per use of wild shape. They have no maximum ability score or natural armor limit. Any part of the druid that separates from their wild-shaped form does not revert back to their natural form, thus druids can still use a form?s natural poison attacks should it have any.
Spell Additions
Polymorph Ally
Level: Sor/Wiz 5
Duration: 10 min/level (D)
Range: Touch
Target: Willing creature touched
Save: None (harmless)
SR: No (harmless)
As polymorph, except as noted. The touched creature assumes a single form chosen by the caster at the time of casting, they touched can revert to their natural form as a full-round action, which ends the spell.
NON PLAYERS HANDBOOK INFO
Sonic Energy: An area of magical silence provided complete immunity to sonic damage unless otherwise stated. Resistance to sonic energy is more common than in the core rules. Creatures with amorphous forms, like water fire and air elementals generally take half sonic damage, if the sonic attack has a reflex save they effectively gain the benefits of improved evasion. There are rumors of dragons that can ?breathe? sonic shockwaves capable of shattering boulders?
Energy Vulnerability: A creature venerable to an energy type (for instance a fire creature is vulnerable to cold effects) suffers a -10 penalty to saving throws against effects with that energy descriptor. If no save is allowed they take 150% damage instead.
Raise Dead: Many aspects of this spell and all similar are entirely campaign dependent.
Item Creation: Creating more than one item where the total costs less than 1000 GP can be accomplished in one day.
Spell Research: Spell research takes 1 day / spell level and costs 200 GP/day. This replaces the standard costs (time and money) to scribe the spell into a spell book. This is non-magical work and can be interrupted and resumed, though one day is spent getting back into the research in which no progress is made (this day does not incur a GP cost). In addition you produce a single scroll of the spell at then end of research if you wish to spend the necessary GP & EXP.
