As our product gets more features and more complicated configuration we decided to simplify the menu and create one source of the settings. In the new setting page, you can change your PHP version, allow billing through CLI to use Brancher Nodes, change your plan through CLI, etc (which was previously in Change plan > Settings), or proceed to transfer ownership, change plan, change SLA or cancel the subscription.
You will also see a clear notification that your plan is canceled/ended and when is the expiration date, if applicable.
