Patch 1.04 is now available via the autoupdater. We will probably use this version for our game on February 11, pending feedback from the community on any issues with the patch. Some of the features of the patch are the return of the "V" key to issue voice commands and emotes, improved functionality of the hotbar, improvement of tree textures, display support for the Logitech G15 keyboard (sweet!), bugfixes, and several improvements to the toolset and DM client.
In the NWN2 official forums, there is a lengthy series of posts in a thread, explaining what is coming in patch 1.03. The patch includes a multitude of fixes and additions, and even makes some changes to the camera. They continue to add to the DM client as well. Obsidian is hoping to have the beta patch out this week, with the patch then released the following week.
