I install eclipse 3.7.2 latest version, when I go to "Help"->"Install new software", and add the site ""
but it only showed 0.4.1 & 0.4.0
The whole process is following the guide at
Why the stable 0.5.x version didn't show? I want to install a stable version in my eclipse.
Besides, the testing site looks ok, the 0.6.x version is shown normally.
