 ### Improvement
 
-- Feat: Support post-quantum `X25519Kyber768Draft00` for incoming TLS initiation. This is non-default feature [feature: `post-quantum`]. Upstream connection to backend applications does not yet support PQC.
+- Feat: Support post-quantum `X25519Kyber768Draft00` for incoming and outgoing TLS initiation. This is non-default feature [feature: `post-quantum`].
 - Feat: emit WARN messages if there exist unused and unsupported options specified in configuration file.
 - Docs: `rpxy.io` is now available for the official website of `rpxy`.
 - Refactor: lots of minor improvements

 [^pure_rust]: Doubtfully can be claimed to be written in pure Rust since current `rpxy` is based on `aws-lc-rs` for cryptographic operations.
 
-By default, `rpxy` provides the *TLS connection sanitization* by correctly binding a certificate used to establish a secure channel with the backend application. Specifically, it always keeps the consistency between the given SNI (server name indication) in `ClientHello` of the underlying TLS and the domain name given by the overlaid HTTP HOST header (or URL in Request line) [^1]. Additionally, as a somewhat unstable feature, our `rpxy` can handle the brand-new HTTP/3 connection thanks to [`quinn`](https://github.com/quinn-rs/quinn), [`s2n-quic`](https://github.com/aws/s2n-quic) and [`hyperium/h3`](https://github.com/hyperium/h3).[^h3lib] Furthermore, `rpxy` supports the automatic issuance and renewal of certificates via [TLS-ALPN-01 (RFC8737)](https://www.rfc-editor.org/rfc/rfc8737) of [ACME protocol (RFC8555)](https://www.rfc-editor.org/rfc/rfc8555) thanks to [`rustls-acme`](https://github.com/FlorianUekermann/rustls-acme), and the hybridized post-quantum key exchange [`X25519Kyber768Draft00`](https://datatracker.ietf.org/doc/draft-tls-westerbaan-xyber768d00/)[^kyber] for TLS initiation thanks to `rustls-post-quantum` crate.

  [^h3lib]: HTTP/3 libraries are mutually exclusive. You need to explicitly specify `s2n-quic` with `--no-default-features` flag. Also note that if you build `rpxy` with `s2n-quic`, then it requires `openssl` just for building the package.
