### Breaking Changes
- Removed support for Kotti network (ETC) [#5816](https://github.com/hyperledger/besu/pull/5816)
- Layered transaction pool implementation is now stable and enabled by default, so the following changes to experimental options have been done [#5772](https://github.com/hyperledger/besu):
- Layered transaction pool implementation is now stable and enabled by default, so the following changes to experimental options have been done [#5772](https://github.com/hyperledger/besu/pull/5772):
- `--Xlayered-tx-pool` is gone, to select the implementation use the new `--tx-pool` option with values `layered` (default) or `legacy`
- `--Xlayered-tx-pool-layer-max-capacity`, `--Xlayered-tx-pool-max-prioritized` and `--Xlayered-tx-pool-max-future-by-sender` just drop the `X` and keep the same behavior
### Additions and Improvements
- Add access to an immutable world view to start/end transaction hooks in the tracing API[#5836](https://github.com/hyperledger/besu/pull/5836)
- Layered transaction pool implementation is now stable and enabled by default. If you want still to use the legacy implementation, use `--tx-pool=legacy`.
By default, the new transaction pool is capped at using 25MB of memory, this limit can be raised using `--layered-tx-pool-layer-max-capacity` options [#5772](https://github.com/hyperledger/besu)

- Tune G1GC to reduce Besu memory footprint, and new `besu-untuned` start scripts to run without any specific G1GC flags [#5879](https://github.com/hyperledger/besu/pull/5879)
- Reduce `engine_forkchoiceUpdatedV?` response time by asynchronously process block added events in the transaction pool [#5909](https://github.com/hyperledger/besu/pull/5909)
