1. New maps!
2. Animals now get sad when a location gets too crowded for them. And they complain about it.
3. All achievements now have their own unique appearance (rather than the generic "badge").
4. The tutorial and new user experience flow got a big upgrade (but most of you reading this won't notice till we next reset).
5. Poisoning trees now makes you feel a little bit guilty and if you keep doing it in rapid succession you feel too guilty to continue for a while.
6. A lot of low-level changes to the server which you will hopefully not notice at all (except that delays which are due to the server being slow will happen less often).
7. Some changes to the client software which should improve the performance of loading new street and reduce overall memory usage.
8. Facebook Invitations have been tweaked so that people who originally signed up with just an email address but who have FB friends playing can add the FB information to their existing sign up (if you know someone in that position who you'd like to invite, send them this link).
9. We have started the process of eliminating the old help channel/global chat. The first step was separating it into two channels "Live Help" and "Global Chat". People will repeatedly use the former to achieve the latter's purpose will be prevented in posting in "Live Help".
