- Version 22.10.0 will require Java 17 to build and run.
- Flexible Privacy Groups (early access) support to Tessera's EC encryptor (contracts modified) [#4282](https://github.com/hyperledger/besu/pull/4282)
* Before this change, the `bytes32` type was used for the enclave public keys, just supporting encryptors with public keys of that length (like the default NaCl)
* For the EC encryptor, the encoded public key length is 91
- `--tx-pool-hashes-max-size` option removed (deprecated in 22.1.3)
- `--Xmerge-support` option remove (deprecated in 22.4.2) [#4518](https://github.com/hyperledger/besu/pull/4518)
- Breaking API changes in the `OperationTracer` interface to enable performance work.
* The `traceExecution` method has been replaced with `tracePreExecution` and `tracePostExecution` methods, called just before and just after operation execution.
* See `DebugOperationTracer` and `StandardJsonTracer` for migration examples.
