When we create a new major feature, and we tested it. It will first release to the "Beta" program. Every gold user can test the new features before they are released to the other plans.
What features can I expect?
When we, for example, release the ability to create Coupon codes (we already support this, but just for the example) we test it locally, in staging and in production on a test account, but to test it further, we'll need to let users use it. So many new major features will be on the beta program.
Do I need to do anything to apply for this?
When you're at our premium (gold) plan, you don't need to do anything. When we release a new feature it will be in the sidebar with the "Beta" tag. And you'll have the ability to test it.
