-  - **Almost done in version 0.4.0**:
-    Split `rpxy` source codes into `rpxy-lib` and `rpxy-bin` to make the core part (reverse proxy) isolated from the misc part like toml file loader. This is in order to make the configuration-related part more flexible (related to [#33](https://github.com/junkurihara/rust-rpxy/issues/33))

 - Cache option for the response with `Cache-Control: public` header directive ([#55](https://github.com/junkurihara/rust-rpxy/issues/55))
 - Consideration on migrating from `quinn` and `h3-quinn` to other QUIC implementations ([#57](https://github.com/junkurihara/rust-rpxy/issues/57))
-- Benchmark with other reverse proxy implementations like Sozu ([#58](https://github.com/junkurihara/rust-rpxy/issues/58))
-  - Currently, Sozu can work only on `amd64` format due to its HTTP message parser limitation... Since the main developer have only `arm64` (Apple M1) laptops, so we should do that on VPS?
