Changelog

[unreleased]

Protocol Changes

• Stabilize account_id_in_function_call_permission feature: enforcing validity of account ids in function call permission.
• Enable TIER1 peer discovery. Validator nodes are now exchanging the public addresses set in config. The TIER1 connections support (direct connections between validators) based on this discovery mechanism will be added soon.

Non-protocol Changes

• use_db_migration_snapshot and db_migration_snapshot_path options are now deprecated. If they are set in config.json the node will fail if migration needs to be performed. Use store.migration_snapshot instead to configure the behaviour #7486
• /status response has now two more fields: node_public_key and validator_public_key. The node_key field is now deprecated and should not be used since it confusingly holds validator key.
• Added near_peer_message_sent_by_type_bytes and near_peer_message_sent_by_type_total Prometheus metrics measuring size and number of messages sent to peers.
• near_peer_message_received_total Prometheus metric is now deprecated. Instead of it aggregate near_peer_message_received_by_type_total metric. For example, to get total rate of received messages use sum(rate(near_peer_message_received_by_type_total{...}[5m])).
• Added near_node_protocol_upgrade_voting_start Prometheus metric whose value is timestamp when voting for the next protocol version starts.
• Few changes to view_state JSON RPC query:
  • The requset has now an optional include_proof argument. When set to true, response’s proof will be populated.
  • The proof within each value in values list of a view_state response is now deprecated and will be removed in the future. Client code should ignore the field.
  • The proof field directly within view_state response is currently always sent even if proof has not been requested. In the future the field will be skipped in those cases. Clients should accept responses with this field missing (unless they set include_proof).
• Backtraces on panics are enabled by default, so you no longer need to set RUST_BACKTRACE=1 environmental variable. To disable backtraces, set RUST_BACKTRACE=0.
• Enable receipt prefetching by default. This feature makes receipt processing faster by parallelizing IO requests, which has been introduced in #7590 and enabled by default with #7661. Configurable in config.json using store.enable_receipt_prefetching.
• neard cmd can now verify proofs from JSON files.
• In storage configuration, the value trie_cache_capacities now is no longer a hard limit but instead sets a memory consumption limit. For large trie nodes, the limits are close to equivalent. For small values, there can now fit more in the cache than previously. #7749
• New options store.trie_cache and store.view_trie_cache in config.json to set limits on the trie cache. Deprecates the never announced store.trie_cache_capacities option which was mentioned in previous change. #7578
• Tracing of work across actix workers within a process: #7866, #7819, #7773.
• Scope of collected tracing information can be configured at run-time: #7701.
• Attach node's chain_id, node_id, and account_id values to tracing information: #7711.
• Change exporter of tracing information from opentelemetry-jaeger to opentelemetry-otlp: #7563.

1.29.0 [2022-08-15]

Protocol Changes

• Stabilized protocol_feature_chunk_only_producers. Validators will now be assigned to blocks and chunks separately.
• The validator uptime kickout threshold has been reduced to 80%
• Edge nonces between peers can now optionally indicate an expiration time

Non-protocol Changes

• The logic around forwarding chunks to validators is improved
• Approvals and partial encoded chunks are now sent multiple times, which should reduce stalls due to lost approvals when the network is under high load
• We now keep a list of "TIER1" accounts (validators) for whom latency/reliability of messages routed through the network is critical
• /debug HTTP page has been improved
• Messages aren't routed through peers that are too far behind
• Log lines printed every 10 seconds are now less expensive to compute
• message broadcasts have been improved/optimized
• network.external_address field in config.json file is deprecated. In fact it has never been used and only served to confuse everyone #7300
• Due to increasing state size, improved shard cache for Trie nodes to put more nodes in memory. Requires 3 GB more RAM #7429

1.28.0 [2022-07-27]

Protocol Changes

• Stabilized alt_bn128_g1_multiexp, alt_bn128_g1_sum, alt_bn128_pairing_check host functions #6813.

Non-protocol Changes

• Added path option to StoreConfig which makes location to the RocksDB configurable via config.json file (at store.path path) rather than being hard-coded to data directory in neard home directory #6938
• Removed testnet alias for localnet command; it’s been deprecated since 1.24 #7033
• Removed undocumented unsafe_reset_all and unsafe_reset_data commands; they were deprecated since 1.25
• Key files can use private_key field instead of secret_key now; this improves interoperability with near cli which uses the former name #7030
• Latency of network messages is now measured #7050

1.27.0 [2022-06-22]

Protocol Changes

• Introduced protobuf encoding as the new network protocol. Borsh support will be removed in two releases as per normal protocol upgrade policies #6672

Non-protocol Changes

• Added near_peer_message_received_by_type_bytes #6661 and near_dropped_message_by_type_and_reason_count #6678 metrics.
• Removed near_<msg-type>_{total,bytes} #6661, near_<msg-type>_dropped, near_drop_message_unknown_account and near_dropped_messages_count #6678 metrics.
• Added near_action_called_count metric [#6679]((near#6679)
• Removed near_action_<action-type>_total metrics [#6679]((near#6679)
• Added near_build_info metric which exports neard’s build information #6680
• Make it possible to update logging at runtime: #6665
• Use correct cost in gas profile for adding function call key #6749

Non-protocol Changes

• Switch to LZ4+ZSTD compression from Snappy in RocksDB #6365
• Moved Client Actor to separate thread - should improve performance #6333

• NEP205: Configurable start of protocol upgrade voting #6309
• Make max_open_files and col_state_cache_size parameters configurable #6584
• Make RocksDB block_size configurable #6631
• Increase default max_open_files RocksDB parameter from 512 to 10k #6607
• Use kebab-case names for neard subcommands to make them consistent with flag names. snake_case names are still valid for existing subcommands but kebab-case will be used for new commands.

1.25.0 [2022-03-16]

Protocol Changes

• max_gas_burnt has been increased to 300.

Non-protocol Changes
