 ### Breaking Changes
 - `--host-whitelist` has been deprecated since 2020 and this option is removed. Use the equivalent `--host-allowlist` instead. 
+- Changed tracer API to include the mining beneficiary in BlockAwareOperationTracer::traceStartBlock [#8096](https://github.com/hyperledger/besu/pull/8096)
 
 ### Upcoming Breaking Changes
 - `MetricSystem::createLabelledGauge` is deprecated and will be removed in a future release, replace it with `MetricSystem::createLabelledSuppliedGauge`

 ### Additions and Improvements
 - Add RPC HTTP options to specify custom truststore and its password [#7978](https://github.com/hyperledger/besu/pull/7978)
 - Retrieve all transaction receipts for a block in one request [#6646](https://github.com/hyperledger/besu/pull/6646)
-
+- Implement EIP-7840: Add blob schedule to config files [#8042](https://github.com/hyperledger/besu/pull/8042)
+- Allow gasPrice (legacy) and 1559 gasPrice params to be specified simultaneously for `eth_call`, `eth_createAccessList`, and `eth_estimateGas` [#8059](https://github.com/hyperledger/besu/pull/8059)
+- Add support for EIP-7702 transaction in the txpool [#8018](https://github.com/hyperledger/besu/pull/8018) [#7984](https://github.com/hyperledger/besu/pull/7984)
 
 ### Bug fixes
 - Fix serialization of state overrides when `movePrecompileToAddress` is present [#8204](https://github.com/hyperledger/besu/pull/8024)
 - Revise the approach for setting level_compaction_dynamic_level_bytes RocksDB configuration option [#8037](https://github.com/hyperledger/besu/pull/8037)
