Just like every other patch that has come out:
- If you update before Avlis updates, you will not be able to play Avlis until you roll back to version 1.67.
- If you accidentally update to 1.68, there is a revert patch here: http://nwn.bioware.com/support/patch_revert_hotu.html
- There will be a News announcement when Avlis is ready to go to 1.68.
- It will be finished when it is finished and not a moment sooner or later. This deadline has worked for the last few years and has never been missed. Coders are good like that.
- Enjoy your stay, and don't forget to tip your waitress.

Ps: Thank you to the players who sent me some very wise PM's before I got this edited.
