Hillmap received a major update: it's faster, more streamlined, significantly less buggy and better for mobile devices. We pushed the beta site up to the main site - so if you've been using the beta site, the main site is now identical.
We will keep the beta site around as we play with new features.
For more info on the new hillmap site check out this and this. As always, if you have questions, comments or concerns give us a shout at email@example.com.
