First off the bad news.... If you're upgrading from a previous version your logo is most likely broken. You can fix it in the menu -> Admin -> Config page. The logo field is now editable. Just set it to "logo-banner-oac-oae" and all will be well. This is the default string. Apologies for the inconvenience and this will obviously be fixed next release.
Now the good news! If you haven't upgraded in a while I'd suggest you take a look at the release notes on the wiki. We have been very busy

We plan on making the next release a bug fix and polish release. No new features, just current bugs addressed and polish where necessary. 1.6.2 is a very, very good release - please do upgrade (and don't forget to fix the logo).
