Version 4.1.0
Linking to PDFs hosted on some proprietary cloud server hurts, especially when you've made the effort to use Free form software.
Suffer no longer! This release comes with an option to upload PDFs to the media library, and makes it easy to link to them from the markdown editor.
Also includes a new form option that makes a best-effort to stop a form from being answered twice on the same browser.
Thank you @wander, @AimeeMaroux, and @neil. ♥
Enjoy!
