Reth v1.1.3 is out -- smol updates, but most importantly breaking changes in the library API, setting us up for Reth as a type-abstracted SDK for building nodes...similar to Cosmos SDK and Substrate, but for the Rollup-centric roadmap.
so far you've been able to overload payload building, txpool, rpcs, the runtime w/ evm or other state transition functions, soon you'll be able to define custom transaction & block types, setting up for innovation and unprecedented customization for both research and product differentiation
stay tuned!
