📄️ Reserved Services
With v0.3, zrok introduced a concept of "reserving" services. The intention is that the zrok control plane will support limits on the number of reserved services (and eventually frontendinstances) that an account is allowed to utilize. Service reservations could also be time-limited, or possibly even bandwidth-limited (the reservation expires after a bandwidth threshold is crossed).
📄️ Public/Private Sharing
In v0.3 new sharing modes and new types of built-in services were introduced.
