Paypal Subscriptions has undergone a Major Version upgrade, with tons of changes made to the way the module works internally as well as externally. One of the major reasons for this was the creation of a separate module, paypal_api, which consolidates all of the Paypal calls and functions, allowing for future modules to more easily integrate with the Paypal system. I am working on a new documentation page which lists all of the function calls and what you can do with them. In the mean time, I highly suggest all current users upgrade to this newest version to take advantage of all of the new features. This new version also comes with a price increase, with another increase expected in August 2009. Current members pay no extra fees, of course, so signing up now will save you money later. I have many new features planned for the next release (4.1) which will come out sometime next week. This release is simply to get a ground-work going so that the newer features can be added. This version changes many things about the module, and there is no upgrade path from 3.2x branch, but the 4.1 release will be easily upgradeable through update.php in your Drupal install, so get the 4.0 version and start building your sites without worry!
