v1.15.0

Notable Changes

New QuantumArithmetic library

This release is the first to add the QuantumArithmetic library by @fedimser to the list of suggested libraries! Check out more about the library at https://github.com/fedimser/quant-arith-re.

Measurement and qubit reuse decompositions handled in QIR generation

This change addresses a long-standing point of confusion regarding how programs compiled for QIR Base profile are displayed in places like the circuit visualizer. By delaying application of decompositions for deferred measurement and avoidance of qubit reuse to the QIR generation step, the stdlib implementation of measurement no longer needs to have a different implementation for Base profile vs other profiles. This should make the displayed circuits match the written code more often. See #2230 for more details.
