 - Breaking: `hyper`-1.0 for both server and client modules.
 - Breaking: Remove `override_host` option in upstream options. Add a reverse option, i.e., `disable_override_host`. That is, `rpxy` always override the host header by the upstream hostname by default.
+- Breaking: Introduced `hyper-tls-backend` feature to use the native TLS engine to access backend applications.
+- Redesigned: Cache structure is totally redesigned with more memory-efficient way to read from cache file, and more secure way to strongly bind memory-objects with files with hash values.
+- Redesigned: HTTP body handling flow is also redesigned with more memory-and-time efficient techniques without putting the whole objects on memory by using `futures::stream::Stream` and `futures::channel::mpsc`
+- Refactor: lots of minor improvements

   - Persistent cache (if possible).
+  - More secure cache file object naming
