 - Removed legacy warp message handlers in favor of ACP-118 SDK handlers.
 - Use `state-history` eth config flag to designate the number of recent states queryable.
 - Moves atomic operations from plugin/evm to plugin/evm/atomic and wraps the plugin/evm/VM in `atomicvm` to separate the atomic operations from the EVM execution.
+- Demoted unnecessary error log in `core/txpool/legacypool.go` to warning, displaying unexpected but valid behavior.
