Attention all ShrinkTheWeb developers and third-party integrators.
Due to popular demand, we have changed the Preview Verification Page to be an optional feature, for those who need to bypass bandwidth limits and want an alternative. Inside pages are also supported, at no charge, for all PVP requests.
UPDATE: Unlimited bandwidth and Inside Page bonuses were removed from the PVP.
No code changes are required regarding this notice. However, if you would like to add support for a "Free" (non-PVP) feature, it works exactly the same as Basic/PLUS. So this will simplify your code quite a bit or give your users another option to choose from.
