The control and quantum_if statements have been unified into one
statement in native QMOD and the SDK under the name control.
SDK: The unified control statement accepts a qbit (q), a q-array
(qbv), or a comparison of a qnum and an integer (n == 5) as the
first argument.
SDK: The old control syntax (with ctrl as the second argument) is
deprecated and will be removed in the next release.
SDK: The quantum_if operator is deprecated and will be removed in the
next release.
Native QMOD: quantum_if is no longer supported, use the new control
statement instead.
SDK: The QParam and Array types are deprecated and will be
removed in the next release.
Instead of QParam[int], use CInt.
Instead of QParam[float], use CReal.
Instead of QParam[bool], use CBool.
Instead of QParam[List[...]], use CArray[...].
Instead of QParam[Array[..., size]], use CArray[..., size].
SDK: Using Python types (int, bool, etc.) in struct declarations
(@struct) is deprecated and will not be supported by the next release.
Instead, use classical data types (CInt, CBool, etc., see above).
Default timeout for sending jobs to AWS changed from 5 minutes to 4 hours.
Deprecations
The error mitigation settings in the execution preferences are no longer
available.
The aer_simulator backend has been removed. Use Classiq's simulator backend
instead (ClassiqSimulatorBackendNames.SIMULATOR).
Enhancements
Improved error messages.
Bug fixes
Fixed a bug preventing execution of circuits synthesized with hardware aware synthesis on Azure and IonQ.
