If you like to try out the beta versions of Easy Digital Downloads, then the plugin released earlier this week will be a huge help for you.
Patrick Garman has released a new plugin called “EDD Beta Tester” that lets you easily run the latest development, or “trunk”, version on your site. The way that it works is it watches the Github repository (where all EDD code is stored) for changes to the master branch. Anytime there are changes on Github that do not exist on your install, WordPress will present you with an update notification, just like any other plugin update notice.
This makes it exceptionally easy to run the most bleeding-edge version of Easy Digital Downloads.
Disclaimer: you should not run trunk on a live production site, not unless you want to risk things breaking.
