Here are the latest development builds of version 3.0.
Please check out the WIKI page on Version 3.x Features especially the Add Chart Button as to where charts are in the current build. The page is being actively worked on but as these are development versions some information may be missing or out of date.

Mac (Universal) Installer - v3.0 [1206 download(s)] (MD5)
For Windows and Mac, version 3.0 installs into different location and the data files are in separate directories compared to version 2.x so that they don’t conflict. You need to copy/paste from your version 2 to your version 3 if you want to use your old files.
