20.10.0

Release format

Hyperledger Besu is moving its versioning scheme to CalVer starting with the 20.10.0 (formerly 1.6.0) release. More information about the specific version of CalVer Besu is using can be found on the wiki.

20.10 Breaking Changes

When upgrading to 20.10, ensure you've taken into account the following breaking changes.

JSON-RPC HTTP Error Codes For Valid Calls (#1426)

Prior versions of Besu would set the HTTP Status 400 Bad Request for JSON-RPC requests that completed in an error, regardless of the kind of error. These responses could include a complete JSON-RPC response with an error field.

In Besu version 20.10, properly formatted requests that have valid parameters (count and content) will return a HTTP Status 200 OK, with an error field if an error occurred. For example, requesting an account that does not exist in the chain, or a block by hash that Besu does not have, will now return HTTP 200 OK responses. Unparsable requests, improperly formatted requests, or requests with invalid parameters will continue to return HTTP 400 Bad Request.

Users of Web3J should note that many calls will now return a result with the error field containing the message whereas before a call would throw an exception with the error message as the exception message.

20.10.0 Additions and Improvements

• Added support for ECIP-1099 / Classic Thanos Fork: Calibrate Epoch Duration. #1421 #1441 #1462
• Added the Open Telemetry Java agent to report traces to a remote backend. Added an example to showcase the trace reporting capabilities.
• Added EvmTool binary to the distribution. EvmTool is a CLI that can execute EVM bytecode and execute ethereum state tests. Documentation for it is available here. #1465
• Added support for the upcoming YOLOv2 ephemeral testnet and removed the flag for the deprecated YOLOv1 ephemeral testnet. #1386
• Added debug_standardTraceBlockToFile JSON-RPC API. This API accepts a block hash and will replay the block. It returns a list of files containing the result of the trace (one file per transaction). #1392
• Added debug_standardTraceBadBlockToFile JSON-RPC API. This API is similar to debug_standardTraceBlockToFile, but can be used to obtain info about a block which has been rejected as invalid. #1403
• Added support for EIP-2929 to YOLOv2. #1387
• Added --start-block and --end-block to the blocks import subcommand #1399
• Added support for multi-tenancy when using the early access feature of onchain privacy group management
• [Reverted] Fixed memory leak in eth/65 subprotocol behavior. It is now enabled by default. #1420, #1348, #1321

Bug Fixes

• Log block import rejection reasons at "INFO" level. Bug #1412
• Fixed NPE when executing eth_estimateGas with privacy enabled. Bug #1404

Previously identified known issues

• Eth/65 loses peers
• Fast sync when running Besu on cloud providers
• Privacy users with private transactions created using v1.3.4 or earlier

Deprecated and Scheduled for removal in Next Release

--privacy-precompiled-address

Deprecated in 1.5.1

• CLI option --privacy-precompiled-address option removed. This address is now derived, based
  on --privacy-onchain-groups-enabled. #1222

• Experimental dns support added via the --Xdns-enabled and --Xdns-update-enabled CLI options. #1247
• Add genesis config option ecip1017EraRounds for Ethereum Classic chains. #1329

Bug Fixes

• K8S Permissioning to use of Service IP's rather than pod IP's which can fail #1190

• Changes not saved to database correctly causing inconsistent private states

Breaking Change to Onchain Privacy Group Management

This early access feature was
changed in a way that makes onchain privacy groups created with previous versions no longer usable.

To enhance control over permissions on the privacy group management contract:

• The enclave key was removed as the first parameter for addParticipant and removeParticipant.
• The owner of the privacy group management contract is the signer of the private transaction that creates
  the privacy group. In the default onchain privacy group management contract implementation, only the
  owner can add and remove participants, and upgrade the management contract.

The onchain privacy support in the current version of the web3js-eea library (v0.9) will not be compatible
with Besu v1.5.3. We are actively working on an upgrade to webj3-eea that will support these changes.

1.5.2

1.5.2

Additions and Improvements

• Experimental offline backup and restore has been added via the operator x-backup-state and operator x-restore-state CLI commands. Data formats will be fluid for as long as the x- prefix is present in the CLI so it is advised not to rely on these backups for disaster recovery. #1235
• Experimental ethstats support added via the Xethstats and Xethstats-contact CLI commands. #1239
• Peers added via the JSON-RPC admin_addPeer and admin_removePeer will be shared or no longer shared via discovery respectively. Previously they were not shared. #1177 contributed by br0tchain.
• New Docker Images (see below). #1277
• Reworked static peer discovery handling. #1292

New Java VMs in Docker Image

• New docker images are being generated to use the latest version of OpenJDK (currently 14.0.1) with the tag suffix of -openjdk-latest, for example 1.5.2-openjdk-latest.
• New docker images are being generated to use GraalVM with the tag suffix of -graalvm, for example 1.5.2-graalvm.
• The existing images based on Java 11 are also being tagged with the suffix -openjdk-11, for example 1.5.2-openjdk-11, as well as 1.5.2.

The intent is that the major Java VM version or Java VM type shipped with the default docker images (latest, 1.5.x, etc.) may be changed during future quarterly releases but will remain consistent within quarterly releases.

Bug Fixes

• Offchain permissioning - fixed bug where sync status check prevented peering if static nodes configured. #1252

• GraphQL queries of miner in IBFT networks will no longer return an error. PR #1282 issue #1272.

Previously identified known issues

• Logs queries missing results against chain head
• Eth/65 loses peers
• Fast sync when running Besu on cloud providers
• Privacy users with private transactions created using v1.3.4 or earlier
• Permissioning issues on Kubernetes
• Restarts caused by insufficient memory can cause inconsistent private state

New and Old Maintainer

• David Mechler has been added as a new maintainer.
• Edward Evans voluntarily moved to emeritus status.
