Mandatory Upgrade

This is a mandatory update for the upcoming Fort Canning Epilogue chain upgrade. It contains key upgrades for the protocol.

Update of mainnet node to v2.11.1 before the chain upgrade block is REQUIRED.

Upgrade Notes

• For nodes >= 2.9.1, this is a drop in upgrade. No reindex required.
• For nodes that are being restored from recent snapshot, as with all updates before: -rescan for the wallet txs and additionally -spv_resync for users who hold BTC. If either isn't used, they may not be shown in the wallet until rescanned/resynced.
• For other nodes, one of the following is required: a fresh sync, the most recent snapshot.
