A lot of new options and some new character portraits are being added to the game (currently in beta-testing). The beta version is available to all Steam users, and more information on opting-in plus a quick list of what's in store can be found in this discussion topic: http://steamcommunity.com/app/251990/discussions/0/620703493333077987/
If you have the time, please come have a look and report your thoughts and any problems you encounter.
There will be a new achievement added to the game but not until this patch leaves beta.
Hope you enjoy the new storylines!
Feature Update (Feb 8 2014)
We've pushed out a small update which adds some new features and fixes a handful of typos. This is not a content update, no new plot has been added.
More details:
Skills screen clearly lists what skills are affected by current mood
Skip button appears on dialogue you've seen before (hide/show button toggled in preferences)
Failed study attempts (when your penalties meant you gained less than ten points and therefore got no skilltext) should now display a message explaining that you were too moody to learn properly
Version number visible on preferences screen
'Save Story' at an ending renamed to 'Show Log'
