# Qiskit Fermions release notes

## 0.1.0

### Prelude

This is the first release of Qiskit Fermions, an extension of Qiskit with tools for fermionic systems. It provides operator data structures, a framework and library for converting those operators to qubit form (mappers), and a framework and library for synthesizing the corresponding quantum circuits. Following Qiskit’s design philosophy, the core of this package is written in Rust and exposed through first-party bindings for both Python and C.
