It's just a quick note to prove I'm still alive. I've been using the dev Weathermap for a project at work for the last few days, and making use of a few of the new features. As soon as I have fixed the really obvious bugs, I'll make an early test release so you can try too.
I wouldn't recommend using the test release as your first Weathermap installation, and I'm not going to help you with your php/GD/apache/cacti setup, but there are enough new things complete to make it interesting. I'll try and write up a few articles about the new things too - templates, z-ordering, rrdtool averaging, a bunch of Cacti UI stuff. There's still some rough edges, and things I want to complete before calling it 0.96, but it should be usable enough.
I expect it will be this weekend, if not before.
