v2.9.1-ccip1.4.6

• chore: bump chain-selectors to v1.0.12 #627

Full Changelog: v2.9.1-ccip1.4.5-release...v2.9.1-ccip1.4.6-release

v2.9.1-ccip1.4.5

Changelog

• Upgrading Chainlink Node to the latest version 2.9.1
• Checking if both source and destination chains are not cursed before starting processing. Besides that, we also verify finality violation and checks are applied on all ocr2 phases #583, #580
• Detecting OnRamp dynamic config changes to properly update Price Registry #544

v2.8.0-ccip1.4.3

High level changelog

• Token pools are no longer configured with specific on- or offRamps but rather chains through chain selectors.

  • Token pools validate callers through the router, which should now be passed in via the constructor
  • Many events around adding/removing/updating allowed ramps now have an updated event around adding/removing/updating chains.
  • Rate limits are set for inbound and outbound explicitly, this is not different from the previous method where onRamps and offRamps are set separately.
    • Rate limits apply per remote chain, not per lane. This means that having multiple lanes enabled doesn't increase risk like it used to.
  • Enabling a chain on a token pool will allow every on- and offRamp that is configured on the router for that remote chain.
    • This also means that token pool ramp permissions do not need to be updated on a lane upgrade

• OffRamp offchain config format changed:

  • Renamed the MaxGasPrice field to DestMaxGasPrice.
  • Removed obsolete SourceFinalityDepth and DestFinalityDepth fields.

  This change is not breaking: the config decoder still accepts old field names.

• CommitStore offchain config format changed:

  • Renamed the MaxGasPrice field to SourceMaxGasPrice.
  • Removed obsolete SourceFinalityDepth and DestFinalityDepth fields.

  This change is not breaking: the config decoder still accepts old field names.

• Minor changes to the Prometheus metrics emitted by plugins

  • ccip_unexpired_report_skipped, ccip_execution_observation_reports_count, ccip_execution_observation_build_duration, ccip_execution_build_single_batch, ccip_execution_reports_iteration_build_batch
    removed, because they didn't introduce any additional value compared to the existing OCR2 metrics.
  • Some metrics added to track details of the processing
    • ccip_unexpired_commit_roots number of unexpired Commit Roots processed by Exec during the OCR2 iteration
    • ccip_number_of_messages_processed number of messages processed by the Exec when building the OCR2 reports and observations
    • ccip_sequence_number_counter latest sequence number that was used for generating Commit Report

• New DynamicPriceGetter implementation of PriceGetter.

  • allows for dynamic price fetching from an aggregator contract as well as using static configuration of token prices.
  • current pipeline implementation is still supported.
  • only one of the two PriceGetter implementations can be used at a time (specified in the job spec).

CCIP 1.2.1 Release

Feature Change Log

• Fixing database passing transaction context between CLO and CCIP plugins

v2.6.0-ccip1.2.0

CCIP 1.2.0 Release

Feature Change Log

USDC

• Support for sending USDC via native integration with Circle’s CCTP protocol.
  • Added USDC token pool to interface with Circle's ITokenMessenger and IMessageReceiver
  • Jobspec changes to support USDC information
  • USDC will be burned by CCTP on source chain and minted by CCTP to token receiver on destination chain.

Billing Changes

• TokenPool destination gas and TokenPool data sizes are now factored in billing to cover NOP costs.
• When the destination chain is a rollup, OnRamp additionally charges CCIP Sender L1 data availability fee to cover NOP costs.
  • GasPrice changed to uint224, with higher-order 112 bits being l1BaseFee of dest L2, lower-order 112 bits being dest gas price.
• Token transfer premium fee min/max changed back to be per-token.

Token Pool Data and Gas Cap

• OnRamp limits return data size from source TokenPool to the token-specific destBytesOverhead. For most tokens, this value is 0.
• OffRamp limits gas passed to TokenPools. Current default to 200K gas.

Public OnRamp

• Allowlist functionalities have been removed from OnRamp. OnRamp is now public.

Chain Expansion

• Add Wemix and Kroma support

Other Misc Changes

• LockReleaseTokenPool contract now has the option to reject outside liquidity.
• MessageId hashing scheme is updated.
• 0-amount token transfer is disallowed.
• PriceRegistry now accepts multiple gas price updates in a single update.
• All contracts implement TypeAndVersion. Previously, TokenPool and PriceRegistry were missing.
• Chain selectors moved to a dedicated repo: https://github.com/smartcontractkit/chain-selectors
• A number of offchain performance optimizations allowing for shorter OCR duration.
• Big versioning initiative to enable straightforward 0-downtime NOP upgrades.
• Fixing nil pointer reference from beta0
• Adding logs to debug missing L1 gas price in #217
• commit plugin - set offchain config n #218
• offchain - explicit initialisations in #219
• Add multi-chain telemetry support, exports OCR telemetry from commit and exec plugins.
• Update collision-resistent BytesOfBytesHashing
