 - Fix tracing in precompiled contracts when halting for out of gas [#7318](https://github.com/hyperledger/besu/issues/7318)
 - Correctly release txpool save and restore lock in case of exceptions [#7473](https://github.com/hyperledger/besu/pull/7473)
 - Fix for `eth_gasPrice` could not retrieve block error [#7482](https://github.com/hyperledger/besu/pull/7482)
+- Correctly drops messages that exceeds local message size limit [#5455](https://github.com/hyperledger/besu/pull/7507)
 - **DebugMetrics**: Fixed a `ClassCastException` occurring in `DebugMetrics` when handling nested metric structures. Previously, `Double` values within these structures were incorrectly cast to `Map` objects, leading to errors. This update allows for proper handling of both direct values and nested structures at the same level. Issue# [#7383](https://github.com/hyperledger/besu/pull/7383)
 - `evmtool` was not respecting the `--genesis` setting, resulting in unexpected trace results. [#7433](https://github.com/hyperledger/besu/pull/7433)
