The small 1.4MB patch was for the updater itself, not the game, it seems.
Edit: Here are the patch notes for the 1.01 patch.
New Stuff
? DM Client ? A beta version of the Dungeon Master Client is now available. You can access it from the NWN2 Launcher, or by running nwn2.exe with the ?dmc switch. This allows you to start a multiplayer game in which you can have a great deal of control over creating, managing, and commanding creatures, placeables, and more. Over the next three monthly patches we will be continuing to add features, fix bugs, and improve the interface.
? New Druid Spells ? Druids have been granted 9 new spells, one for each level. In addition, the feat Natural Spell has been added. Druids that take the Natural Spell feat may cast spells while Polymorphed or Wild Shaped.
* Level 1 - Foundation of Stone: This spell grants a target immunity to knockdown, but reduces their movement speed.
* Level 2 - Body of the Sun: The caster?s body emanates fire, burning nearby creatures.
* Level 3 ? Jagged Tooth: This spell grants a targeted animal the Keen property on one of its natural weapons.
* Level 4 ? Moonbolt: This spell creates a bolt of energy that deals strength damage to living creatures and knocks down undead, giving them penalties on attack rolls and saving throws.
* Level 5 ? Rejuvenation Cocoon: The target of this spell becomes encased in a regenerative cocoon, where they are cured from poison and disease and regenerate health.
* Level 6 ? Tortoise Shell: The caster gains a natural armor bonus of +6, plus an additional 1 per every three caster levels to a maximum of +9.
* Level 7 ? Swamp Lung: This spell causes victims to fall prone for 1-6 rounds, during which time they can catch disease.
* Level 8 ? Storm Avatar: This spell infuses the caster with the energy of a storm, making them immune to missiles, hasting them, and adding damage to their attacks
* Level 9 ? Nature?s Avatar: This spell grants a targeted animal a series of very powerful buffs.
? Water Reflection/Refraction ? Water is now more visually exciting! Users have the option to toggle Water Reflection and Refraction on in the Options Menu under the Advanced Graphics tab. Note: These settings can cause slowdowns on older hardware.
? Client Packs ? Module makers can now create Client Packs in the toolset, which can be placed in clients My Documents\pwc\ folder to allow users to connect to Multiplayer Games for which they do not have the module. These .pwc files contain only the data absolutely necessary to run the module on the client side are useful if, for instance, you are running a persistent world and do not wish to allow clients to open your module with all of its areas, creatures, and scripts visible.
