Microsoft has announced the first major upgrade to its Quantum Development Kit since its introduction last year. It has added several new features designed to open the platform to a wider array of developers, including support for Linux and macOS, as well as additional open source libraries. Further, the kit will be interoperable with the Python computing language. Microsoft announced the Quantum Development Kit at its Ignite conference last fall. It launched the free preview about three months later, featuring the new Q# programming language.
