smartcontractkit/chainlink v2.7.0 on GitHub

Added

Added new configuration field named LeaseDuration for EVM.NodePool that will periodically check if internal subscriptions are connected to the "best" (as defined by the SelectionMode) node and switch to it if necessary. Setting this value to 0s will disable this feature.
Added multichain telemetry support. Each network/chainID pair must be configured using the new fields:

[[TelemetryIngress.Endpoints]]
Network = '...' # e.g. EVM. Solana, Starknet, Cosmos
ChainID = '...' # e.g. 1, 5, devnet, mainnet-beta
URL = '...'
ServerPubKey = '...'

These will eventually replace TelemetryIngress.URL and TelemetryIngress.ServerPubKey. Setting TelemetryIngress.URL and TelemetryIngress.ServerPubKey alongside [[TelemetryIngress.Endpoints]] will prevent the node from booting. Only one way of configuring telemetry endpoints is supported.

Added bridge_name label to pipeline_tasks_total_finished prometheus metric. This should make it easier to see directly what bridge was failing out from the CL NODE perspective.
LogPoller will now use finality tags to dynamically determine finality on evm chains if UseFinalityTags=true, rather than the fixed FinalityDepth specified in toml config

Changed

P2P.V1 is now disabled (Enabled = false) by default. It must be explicitly enabled with true to be used. However, it is deprecated and will be removed in the future.
P2P.V2 is now enabled (Enabled = true) by default.

Upcoming Required Configuration Changes

Starting in v2.9.0:

TelemetryIngress.URL and TelemetryIngress.ServerPubKey will no longer be allowed. Any TOML configuration that sets this fields will prevent the node from booting. These fields will be replaced by [[TelemetryIngress.Endpoints]]
P2P.V1 will no longer be supported and must not be set in TOML configuration in order to boot. Use P2P.V2 instead. If you are using both, V1 can simply be removed.

Removed

Removed the ability to set a next nonce value for an address through CLI
