 - New [Microsoft.Quantum.Random namespace](xref:microsoft.quantum.random), providing a more convenient way to sample random values from within Q# programs. ([QuantumLibraries#311](https://github.com/microsoft/QuantumLibraries/pull/311), [qsharp-runtime#328](https://github.com/microsoft/qsharp-runtime/pull/328))
 - Improved [Microsoft.Quantum.Diagnostics namespace](xref:microsoft.quantum.diagnostics) with new [`DumpOperation` operation](xref:microsoft.quantum.diagnostics.dumpoperation), and new operations for restricting qubit allocation and oracle calls. ([QuantumLibraries#302](https://github.com/microsoft/QuantumLibraries/pull/302))

 - Support for automatically loading `.csproj` files for IQ#/Python hosts, which allows external project or package references to be loaded at initialization time. See the guide for using [Q# with Python and Jupyter Notebooks](xref:microsoft.quantum.guide.host-programs) for more details.
 - Added ErrorCorrection.Syndrome sample.
 - Added tunable coupling to SimpleIsing.
