v1.6.0

Welcome to the v1.6.0 release of the Azure Quantum Development Kit!

The big feature in this release is the ability to compile Q# programs to QIR that require "Adaptive Profile" capabilities. This enables programs to take advantage of the latest capabilities of quantum hardware, such as the ability to perform mid-circuit measurement of qubits, branch based on the results, and perform some classical computations at runtime. For more details, see https://aka.ms/qdk.qir.

We've added or updated a number of samples that can leverage Adaptive Profile capabilities, such as the Three Qubit Repetition Code and the Iterative Phase Estimation notebook. Please do try it out and give us your feedback!

As part of the above work, the previous code generation approach was replaced, even in the non-Adaptive ("base profile") case. Please log an issue if you see any unexpected change in behavior.

Other notable new features include Q# linting support in Jupyter Notebooks, CodeActions in VS Code to fix certain Q# errors, Q# library documentation inside VS Code, and more!
