You would need to be a Patreon subscriber in order to access the perks and benifits of the Patreon edition. You can see the 'README.txt' file included with Jav-It for more details.
Bare in mind, Patreon is a means of supporing the project via a subscription. That means if you are not a subscriber, you will not have continued access to Patreon perks, benifits, or features.
