As we are receiving lots of requests everyday to enable developer license, finally we couldn’t ignore it. So we made the developer license enabled for you. So if you are a developer and using download manager for your client, you will not need to buy license of wpdm pro plugin and add-ons for every site separately. As you can use developer license now, which you can use for unlimited sites and additionally getting all add-ons for free. Developer license will get automatic update free for 1 year with priority support. After 1 year you need to pay 66% of original price to get update and continue with priority support, but you can use old version if you don’t want to renew.
