Additions and Improvements

• Added trace_block JSON RPC API #449
• Added pulledStates and knownStates to the EthQL syncing query and eth_syncing JSON-RPC api #565

Bug Fixes

• Fixed file parsing behaviour for privacy enclave keystore password file #554 (thanks to magooster)
• Fixed known issue with being unable to re-add members to onchain privacy groups #471

Updated Early Access Features

• Onchain privacy groups with add and remove members. Known issue resolved (see above).
• TRACE API now includes trace_block, trace_replayBlockTransactions, and trace_transaction.
  Fixed some issues on the trace replay block transactions API #522.

Known Issues

Fast sync defaulting to full sync

• When fast sync cannot find enough valid peers rapidly enough, Besu defaults to full sync.

Workarounds:

1. To re-attempt fast syncing rather than continue full syncing, stop Besu, delete your database,
   and start again.
2. When fast syncing, explicitly disable pruning using --pruning-enabled=false to reduce the likelihood
   of encountering the pruning bug.

A fix to remove the default to full sync is in progress
is being actively worked on.

Error full syncing with pruning

• Error syncing with mainnet on Besu 1.3.7 node - MerkleTrieException #BESU-160
  The associated error is Unable to load trie node value for hash and is caused by the combination of
  full sync and pruning.

Workarounds:

1. Explicitly disable pruning using --pruning-enabled=false when using fast sync.
2. If the MerkleTrieException occurs, delete the database and resync.

A fix for this issue is being actively worked on.

Bootnodes must be validators when using onchain permissioning

• Onchain permissioning nodes can't peer when using a non-validator bootnode #BESU-181

Workaround -> When using onchain permissioning, ensure bootnodes are also validators.
