1.5 Breaking changes

When upgrading to 1.5, ensure you've taken into account the following breaking changes.

Docker users with volume mounts

To maintain best security practices, we're changing the user:group on the Docker container to besu.

What this means for you:

• If you are running Besu as a binary, there is no impact.
• If you are running Besu as a Docker container and have a volume mount for data, ensure that the
  permissions on the directory allow other users and groups to r/w. Ideally this should be set to
  besu:besu as the owner.

Note that the besu user only exists within the container not outside it. The same user ID may match
a different user outside the image.

If you’re mounting local folders, it is best to set the user via the Docker —user argument. Use the
UID because the username may not exist inside the docker container. Ensure the directory being mounted
is owned by that user.

Remove Manual NAT method

The NAT manager MANUAL method has been removed.
If you have have been using the MANUAL method, use the NONE method instead. The behavior of the
NONE method is the same as the previously supported MANUAL methods.

Privacy users

Besu minor version upgrades require upgrading Orion to the latest minor version. That is, for
Besu <> Orion node pairs, when upgrading Besu to v1.5, it is required that Orion is upgraded to
v1.6. Older versions of Orion will no longer work with Besu v1.5.

1.5

Additions and Improvements

• Public Networks Default to Fast Sync: The default sync mode for named permissionless networks, such as the Ethereum mainnet and testnets, is now FAST.
  • The default is unchanged for private networks. That is, the sync mode defaults to FULL for private networks.
  • Use the --sync-mode command line option to change the sync mode. #384
• Proper Mining Support: Added full support for eth_hashrate and eth_submitHashrate. It is now possible to have the hahsrate when we mine with a GPU mining worker #1063
• Performance Improvements: The addition of native libraries (#775) and changes to data structures in the EVM (#1089) have improved Besu sync and EVM execution times.
• Tracing API Improvements: The Tracing API is no longer an Early Access feature and now has full support for trace_replayBlockTransactions, trace_Block and trace_transaction.
• New Plugin API Block Events: BlockAdded and BlockReorg are now exposed via the Plugin API #637.

• Add CLI option --Xnat-kube-pod-name to specify the name of the loadbalancer used by the Kubernetes nat manager #1078

Bug fixes

Known Issues

Known issues are open issues categorized as Very High or High impact.

Previously identified known issues

• Scope of logs query causing Besu to hang
• Eth/65 loses peers
• Fast sync when running Besu on cloud providers
• Privacy users with private transactions created using v1.3.4 or earlier

Additions and Improvements

• local permissioning TOML config now supports additional keys (nodes-allowlist and accounts-allowlist).
  Support for nodes-whitelist and accounts-whitelist will be removed in a future release.
• CLI now supports --host-allowlist. Support for --host-whitelist will be removed in a future release.
• Additional Allowlist JSON RPC endpoints for permissioning now supported. Whitelist endpoints will be removed in a future release.
  • Add perm_getNodesAllowlist as an alternative equivalent to perm_getNodesWhitelist
  • Add perm_addNodesToAllowlist as an alternative equivalent to perm_addNodesToWhitelist
  • Add perm_removeNodesFromAllowlist as an alternative equivalent to perm_removeNodesFromWhitelist
  • Add perm_getAccountsAllowlist as an alternative equivalent to perm_getAccountsWhitelist
  • Add perm_addAccountsToAllowlist as an alternative equivalent to perm_addAccountsToWhitelist
  • Add perm_removeAccountsFromAllowlist as an alternative equivalent to perm_removeAccountsFromWhitelist
• Add missing mixHash field for eth_getBlockBy* JSON RPC endpoints
