eplanet has been sadly neglected for some time. On the plus side, e17 is stable enough that it rarely has issues large enough to affect the module. On the down side, there’s still a lot of features to be added.
Today there’s a couple of small updates to make the module play nicely with the very latest code from svn. In the last few weeks or months some of the multi-screen stuff has been improved, which actually makes eplanet work better on those systems. I love it when my code gets better without me having to do anything!
As always, full details and installation instructions are on the eplanet page.
