We’ve updated Exploit: Zero Day to 0.64.0 as part of the “Razor” release. Changes include:

• Replacement of our payment processor. We've talked about the upcoming change on our podcast, but we're switching from a mixture of Stripe/Paypal + TaxCloud to Paddle, which should over a better purchasing (and accounting!) experience.
• Replacement of bitly with shlink for links to shared systems and clusters. Players shouldn't notice any difference in behavior.
