-ormsgpack is a fast msgpack library for Python. It is a fork/reboot of [orjson](https://github.com/ijl/orjson)
-It serializes faster than [msgpack-python](https://github.com/msgpack/msgpack-python) and deserializes a bit slower (right now).
-It supports serialization of:
-[dataclass](#dataclass),
-[datetime](#datetime),
-[numpy](#numpy),
-[pydantic](#pydantic) and
-[UUID](#uuid) instances natively.
-
-Its features and drawbacks compared to other Python msgpack libraries:
-
-* serializes `dataclass` instances natively.
-* serializes `datetime`, `date`, and `time` instances to RFC 3339 format,
-e.g., "1970-01-01T00:00:00+00:00"
-* serializes `numpy.ndarray` instances natively and faster.
-* serializes `pydantic.BaseModel` instances natively
-* serializes arbitrary types using a `default` hook
-
-ormsgpack supports CPython 3.8, 3.9, 3.10, 3.11, 3.12 and 3.13.
-ormsgpack does not support PyPy. Releases follow semantic
-versioning and serializing a new object type without an opt-in flag is
-considered a breaking change.
