Private State Migration
Hyperledger Besu v1.4 implements a new data structure for private state storage that is not backwards compatible.
A migration will be performed when starting v1.4 for the first time to reprocess existing private transactions
and re-create the private state data in the v1.4 format.
If you have existing private transactions, see migration details.
Additions and Improvements
- Automatic Transaction Log Bloom Filter Caching
Add a new option --auto-logs-bloom-indexing-enabled which defaults to true. This performs the equivalent of the operator generate-log-bloom-cache CLI task or admin_generateLogBloomCache RPC call for each block as it arrives, in addition to caching older logs on first startup.
