As of NV27, all implementations support v2 snapshots with F3 data. On calibnet, all nodes must have this support, on mainnet this will happen today. Nonetheless, serving v2 snapshots for mainnet is postponed until ~Oct 7th as to avoid clashes with the network upgrade itself/weekend/Golden Week.

The snapshot service currently serves the latest v1 snapshots by default; this will change:

• calibnet will start serving v2 snapshots - Sep 24th
• mainnet will start serving v2 snapshots - Oct 9th
