Helper's development version 0.3.1 was released today. Along with minor code refactoring and development dependency updates, Helper's includes a new set of RSS/Atom methods.
For those creating RSS/Atom XML doc's,
Atom::getClosing() in combination, will return a valid Atom 1.0 XML string. This string can be passed directory to a controller that is providing a RSS/Atom feed endpoint.
Improvements to Helper/Atom are soon to come, until then Happy New Years!
