Tomorrow I will be disabling new subscriptions for the Pro (€2) tier. The €4 tier (currently called Resolve) will be renamed to Pro. It will stay this way at least until the end of November.
For existing patrons nothing will change. The limits of your account will stay the same and the price of the subscription too. If you upgrade your subscription to €4 you won't be able to downgrade again.
Today I will be updating the website to reflect the changes. The benefits of the tiers will not change. This means that the new Pro tier will have a file expiry time of 240 days and a monthly data transfer limit of 2 TB.
