Summary

Indexer line for the ledger 9 network upgrade on Mainnet. Requires a full re-index from genesis.

• Indexes the chain across the switch from ledger 8 to ledger 9 and follows the chain across the upgrade
• Requires a full re-index from genesis; wipe the indexer and ledger databases together
• 4.3.800 to 4.4.101 is not an upgrade path
• Serves post-upgrade state for contracts untouched since the switch (breaking)
• A contract action subscription without an offset delivers only new actions; pass an offset such as height 0 to replay history (breaking)
• Reports DUST capacity correctly after the DUST reset; required by wallet SDK 2.0.0
• Pairs with node 2.1.101 and ledger 9.1.0.1
