Roblox Premium

Roblox Premium is a membership that replaces the traditional Builders Club. It is primarily a rebranding, as most of the current benefits were also provided with Builders Club. Since mid-August 2019, it is gradually being rolled out to select users, with priority towards those with existing BC memberships who live in the United Kingdom.

History
Premium was first confirmed on June 10, 2019, after "Premium" was added to the MembershipType enum. It was first speculated when an icon called "icon_premium-16.png" was added to the Roblox files. Later, changes to CoreScripts further increased the idea that a new membership was being added. This can also be confirmed through the content within the url of the upgrade page  as it contains "premium" in it. Web APIs have also been updated to give the idea a new membership is being added. For example, https://www.roblox.com/mobileapi/userinfo has "IsPremium" at the end.

It was confirmed that Premium will be replacing Builders Club, when the BC overlay endpoint was modified on August 10, 2019, to always return "empty.png".

Plans
Membership plans for Roblox Premium are categorized by how much monthly Robux they provide. Compared to Builders Club, all memberships share the same name and icons rather than having distinct ones, and Robux is provided all at once after each renewal date instead of gradually each day.

Roblox Premium Benefits
Similar to Builders Club, Premium members will receive an in-game badge and profile badge.

First members

Trivia

 * The implementation of this membership is widely suspected to result in Builders Club bonus items such as the Builders Club Hard Hat becoming unavailable.
 * The API endpoint https://premiumfeatures.roblox.com/v1/users/1/subscriptions can be used to see whether a user has a Lifetime subscription as well as when their expiration and renewal dates are.
 * Replace the '1' with the ID of the user whose membership is desired to be checked.
 * Users who had the prototype version of this exclusive membership do not own a corresponding Roblox badge showcasing the ownership of Premium. They instead have the Outrageous Builders Club badge on their profile.
 * This could be caused by the highest level of Builders Club (OBC) being directly replaced by Premium given to these users. A badge of the membership is yet to be implemented.
