+### [rkyv]
+
+[rkyv] is a zero-copy deserialization framework for Rust. It's similar to FlatBuffers
+and Cap'n Proto and can be used for data storage and messaging.
+
+A [benchmark][rust-serialization-benchmark] was put together to compare rkyv
+against other leading serialization solutions and gather feedback and use
+cases for development. A [summary and analysis][rkyv-is-faster-than] of the
+results is also available.
+
+Version 0.5 is hot off the presses and rolls up features from the 0.4
+development cycle:
+
+- Derive macros can now implement `PartialEq` and `PartialOrd` between
+  archived and unarchived types
+- Custom type bounds for serialization and deserialization can be added
+  with derive attributes
+- Helper types like [AlignedVec][rkyv-AlignedVec] and
+  [Infallible][rkyv-Infallible] were introduced to improve ergonomics
+- `const_generics` are now enabled by default
+- Helper functions have been added to make getting root objects easier
+- Several bugfixes and performance improvements
+
+A [feedback issue][rkyv-feedback] is still open for providing feedback on
+further development.
