v1.6.2

This version is backwards compatible to v1.6.0. It is optional, but encouraged.

Config Options

• Removed --coreth-config.
• Added --throttler-inbound-node-max-processing-msgs.
• Added --db-config-file.

API

• API method avm.exportAVAX has been removed. Use avm.export instead.
• API method avm.importAVAX has been removed. Use avm.import instead.
• API method info.peers now treats the PublicIP field as option and only populates it when a valid IP is provided.
• API client platform.getValidatorsAt has been added.
• API client admin.lockProfile has been fixed to correctly call lockProfile.
• API client health.health has been fixed to properly handle responses from an unhealthy server.
• Improved responses from the Health Check API to be more descriptive.

Benchlist

• Changed the minimum time a validator must be unresponsive and the maximum amount of time a validator will be benched for. These used to be 5 minutes and 30 minutes, respectively, and are now 2.5 minutes and 15 minutes.

Database

• Allowed users to specify database config with flag --db-config-file.

Subnets

• Added the ability for a client to configure a subnet as private to restrict membership to only approved validators.

Networking

• Changed the default size of the inbound at-large message allocation from 32 MiB to 6 MiB.
• Changed the default size of the outbound at-large message allocation from 32 MiB to 6 MiB.
• Changed the default maximum number of bytes a node can take from the inbound at-large message allocation from 4 MiB to 2 MiB.
• Changed the default maximum number of bytes a node can take from the outbound at-large message allocation from 4 MiB to 2 MiB.
• Added additional inbound message rate-limiting. A node will not read more messages from a peer until it is processing less than --throttler-inbound-node-max-processing-msgs from that peer.
• Changed default number of non-validators an AppGossip message is gossiped to from 2 to 0.
• Changed default number of validators an AppGossip message is gossiped to from 4 to 6.
• Introduced the ability for a VM to gossip to specific validators rather than just uniformly randomly.
• Fixed an issue that caused some nodes to never attempt to reconnect to a previously disconnected node.

ProposerVM

• Introduced a pessimistic P-chain height lag to improve stability during high P-chain block issuance.
• Correctly applied the requested block delay.

Metrics

• Removed API request histogram metrics from the X-chain and the P-chain.
• Added P-chain mempool metrics.
• Added validator_sets metrics to the platformvm.

Other

• Refactored node startup and shutdown to avoid ungraceful shutdowns in the event that the node is started and then immediately stopped.
• Fixed P-chain mempool to correctly track the number of allocated bytes.
• Upgraded the C-chain to run geth 1.10.9.
• Supported abigen for the C-chain.
• Added support for pre-image support on the C-chain.
• Added support for the fee history endpoint on the C-chain.
• Refactored ID aliasing to better support GRPC tests.
• Removed the end-to-end test branch matchup logic.
• Removed the deprecated main entry point for the database migration's process manager.
