In case you are not aware, the Eagle product has changed hands again. Autodesk is now the new owner and... the product is now a subscription-based product. It must use a connect back to base link at least once every 14 days to check your eligibility for continued use.
The user community is understandably up in arms after their official representative stated a few months ago that they would not adopt the subscription model and now have. http://www.eevblog.com/forum/eag...
Looks like it is time to investigate KiCad or to stay with an old model without the internet linking.
