Updated: we release a mandatory hot-fix v2.2.1
This version is a mandatory release.
From this version, TomoChain will support TomoX Protocol.
It means that the node that runs TomoChain V2.2+ can store orderbook (spot trading, p2p lending) and process order-matching.
TomoChain v2.2+ also added tomox and posv JSON-RPC APIs to allow the clients to interact with nodes using TomoX protocol.
All the nodes (Masternodes, Fullnodes) have to update to this version before the hard-fork. The hard-fork will happen at block number: 20581700 (Est. 2020-05-12 00:02 UTC).
