This version is backwards compatible to v1.7.0. It is optional, but encouraged.

Consensus

• Added asynchronous processing of App.* messages.
• Added height indexing support to the proposervm and rpcchainvm. If a node is updated to >=v1.7.5 and then downgraded to <v1.7.5, the user must enable the --reset-proposervm-height-index=true flag to ensure the proposervm height index is correctly updated going forward.
• Fixed bootstrapping job counter initialization that could cause negative ETAs to be reported.
• Fixed incorrect processing check that could log incorrect information.
• Removed incorrect warning logs.

Miscellaneous

• Added tracked subnets to be reported in calls to the info.peers API.
• Updated gRPC implementations to use buf tooling and standardized naming and locations.
• Added a consistent hashing implementation to be used in future improvements.
• Fixed database iteration invariants to report ErrClosed rather than silently exiting.
• Added additional sanity checks to prevent users from incorrectly configuring their node.
• Updated log timestamps to include milliseconds.

Coreth

• Added beta support for offline pruning.
• Refactored peer networking layer.
• Enabled cheap metrics by default.
• Marked RPC call metrics as expensive.
• Added Abigen support for native asset call precompile.
• Fixed bug in BLOCKHASH opcode during traceBlock.
• Fixed bug in handling updated chain config on startup.

This version is backwards compatible to v1.7.0. It is optional, but encouraged.

The first startup of the C-Chain will take a few minutes longer due to an index update.

Consensus

• Removed deprecated Snowstorm consensus implementation that no longer aligned with the updated specification.
• Updated bootstrapping logs to no longer reset counters after a node restart.
• Added bootstrapping ETAs for fetching Snowman blocks and executing operations.
• Renamed the MultiPut message to the Ancestors message to match other message naming conventions.
• Introduced Whitelist conflicts into the Snowstorm specification that will be used in future X-chain improvements.
• Refactored the separation between the Bootstrapping engine and the Consensus engine to support Fast-Sync.

Coreth

• Added an index mapping height to the list of accepted atomic operations at that height in a trie. Generating this index will cause the node to take a few minutes longer to startup the C-Chain for the first restart.
• Updated Geth dependency to v1.10.15.
• Updated networkID to match chainID.

VMs

• Refactored platformvm rewards calculations to enable usage from an external library.
• Fixed platformvm and avm UTXO fetching to not re-iterate the UTXO set if no UTXOs are fetched.
• Refactored platformvm status definitions.
• Added support for multiple address balance lookups in the platformvm.
• Refactored platformvm and avm keystore users to reuse similar code.

RPCChainVM

• Returned a 500 InternalServerError if an unexpected gRPC error occurs during the handling of an HTTP request to a plugin.
• Updated gRPC server's max message size to enable responses larger than 4MiB from the plugin's handling of an HTTP request.

Configs

• Added --stake-max-consumption-rate which defaults to 120,000.
• Added --stake-min-consumption-rate which defaults to 100,000.
• Added --stake-supply-cap which defaults to 720,000,000,000,000,000 nAVAX.
• Renamed --bootstrap-multiput-max-containers-sent to --bootstrap-ancestors-max-containers-sent.
• Renamed --bootstrap-multiput-max-containers-received to --bootstrap-ancestors-max-containers-received.
• Enforced that --staking-enabled=false can not be specified on public networks (Fuji and Mainnet).

Metrics

• All multi_put metrics were converted to ancestors metrics.

Miscellaneous

• Improved corruptabledb error reporting by tracking the first reported error.
• Updated CPU tracking to use the proper EWMA tracker rather than a linear approximation.
• Separated health checks into readiness, healthiness, and liveness checks to support more fine-grained monitoring.
• Refactored API client utilities to use a Context rather than an explicit timeout.

This version is backwards compatible to v1.7.0. It is optional, but encouraged.

Consensus

• Introduced a notion of vertex conflicts that will be used in future X-chain improvements.

Coreth

• Added an index mapping height to the list of accepted atomic transactions at that height. Generating this index will cause the node to take approximately 2 minutes longer to startup the C-Chain for the first restart.
• Fixed bug in base fee estimation API that impacted custom defined networks.
• Decreased minimum transaction re-gossiping interval from 1s to 500ms.
• Removed websocket handler from the static vm APIs.

Database

• Reduced lock contention in prefixDBs.

Networking

• Increase the gossip size from 6 to 10 validators.
• Prioritized Connected and Disconnected messages in the message handler.

Miscellaneous

• Notified VMs of peer versions on Connected.
• Fixed acceptance broadcasting over IPC.
• Fixed 32-bit architecture builds for AvalancheGo (not Coreth).

This version is backwards compatible to v1.7.0. It is optional, but encouraged.

Coreth

• Fixed memory leak in the estimate gas API.
• Reduced the default RPC gas limit to 50,000,000 gas.
• Improved RPC logging.
• Removed pre-AP5 legacy code.

PlatformVM

• Optimized validator set change calculations.
• Removed storage of non-decided blocks.
• Simplified error handling.
• Removed pre-AP5 legacy code.

Networking

• Explicitly fail requests with responses that failed to be parsed.
• Removed pre-AP5 legacy code.

Configs

• Introduced the ability for a delayed graceful node shutdown.
• Added the ability to take all configs as environment variables for containerized deployments.

Utils

• Fixed panic bug in logging library when importing from external projects.
