24.5.0-RC1 is currently still burning in, but it is functionally equivalent to [the test run on these nodes last week](https://grafana.o11y.web3factory.consensys.net/d/_Mqt4ksnz/besu-full?orgId=19&var-system=dev-elc-bu-tk-mainnet-jframe-halt-1&var-system=dev-elc-bu-tk-mainnet-jframe-halt-10&var-system=dev-elc-bu-tk-mainnet-jframe-halt-2&var-system=dev-elc-bu-tk-mainnet-jframe-halt-3&var-system=dev-elc-bu-tk-mainnet-jframe-halt-4&var-system=dev-elc-bu-tk-mainnet-jframe-halt-5&var-system=dev-elc-bu-tk-mainnet-jframe-halt-6&var-system=dev-elc-bu-tk-mainnet-jframe-halt-7&var-system=dev-elc-bu-tk-mainnet-jframe-halt-8&var-system=dev-elc-bu-tk-mainnet-jframe-halt-9&var-sync_task_quantile=All&var-executor=All&var-vertx_pool_name=All&var-protocol_inbound=All&var-protocol_outbound=All&var-diskdevices=%5Ba-z%5D%2B%7Cnvme%5B0-9%5D%2Bn%5B0-9%5D%2B&var-overview_engine_percentiles=All&var-txpool_layer=All&from=1714462487150&to=1715067287150) (24.4.0-RC3 + haltfix2)
