# Release Notes ## 0.1.0a1 ### Prelude This is the first release of Qiskit Bosons, an extension of Qiskit with tools for bosonic systems. It provides a bosonic operator data structure, a framework and library for encoding those operators into qubits (mappers), and a framework and library for bosonic circuits that a transpilation pipeline synthesizes into qubit circuits. Following Qiskit’s design philosophy, the core of this package is written in Rust and exposed through first-party Python bindings. This is an alpha release: the API may change in response to feedback. Please [open an issue](https://github.com/Qiskit/qiskit-bosons/issues/new/choose) to share yours.
