Config

• Added flag throttler-inbound-bandwidth-refill-rate, which specifies the max average inbound bandwidth usage of a peer.
• Added flag throttler-inbound-bandwidth-max-burst-size, which specifies the max inbound bandwidth usage of a peer.

Networking

• Updated peerlist gossiping to use the same mechanism as other gossip calls.
• Added inbound message throttling based on recent bandwidth usage.

Metrics

• Updated avalanche_{ChainID}_handler_gossip_{count,sum} to avalanche_{ChainID}_handler_gossip_request_{count,sum}.
• Updated avalanche_{ChainID}_lat_get_accepted_{count,sum} to avalanche_{ChainID}_lat_accepted_{count,sum}.
• Updated avalanche_{ChainID}_lat_get_accepted_frontier_{count,sum} to avalanche_{ChainID}_lat_accepted_frontier_{count,sum}.
• Updated avalanche_{ChainID}_lat_get_ancestors_{count,sum} to avalanche_{ChainID}_lat_multi_put_{count,sum}.
• Combined avalanche_{ChainID}_lat_pull_query_{count,sum} and avalanche_{ChainID}_lat_push_query_{count,sum} to avalanche_{ChainID}_lat_chits_{count,sum}.
• Added avalanche_{ChainID}_app_response_{count,sum}.
• Added avalanche_network_bandwidth_throttler_inbound_acquire_latency_{count,sum}
• Added avalanche_network_bandwidth_throttler_inbound_awaiting_acquire
• Added avalanche_P_vm_votes_won
• Added avalanche_P_vm_votes_lost

Indexer

• Added method GetContainerByID to client implementation.
• Client methods now return []byte rather than string representations of a container.

C-Chain

• Updated Geth dependency to 1.10.11.
• Added a new admin API for updating the log level and measuring performance.
• Added a new --allow-unprotected-txs flag to allow issuance of transactions without EIP-155 replay protection.

Subnet & Custom VMs
