## 0.5.1 ##

 - General:
    - Unify `TimeType.from_float` between fractions and gmpy2 backend behaviour (fixes issue 529).

## 0.5 ##

 - General:
   - Improve `TimeType` consistency by leveraging str(float) for rounding by default.
   - Add support for sympy==1.5
   - Add volatile parameters. Repetition counts can now be changed at runtime in some cases (useful for DNP). See
     `volatile` kwarg of `create_program`

 - Hardware:
   - Add a `measure_program` method to the DAC interface. This method is used by the QCoDeS integration.
   - Add a `set_measurement_mask` to DAC interface. This method is used by the QCoDeS integration.
   - Add a `get_sample_times` util method to share code for exact and fast sample time calculation
   - Add a driver for Tektronix AWG5000/7000
   - Add a driver for Zurich Instruments HDAWG
   - Warn the user if waveforms need to be concatenated to be compatible with hardware requirements.

- Pulse Templates:
    - Add `__repr__` and `__format__` for easier inspection
    - `MappingPulseTemplate`:
        - `allow_partial_parameter_mapping` is now True as a default. The default can be changed with the class variable `MappingPulseTemplate.ALLOW_PARTIAL_PARAMETER_MAPPING`.
        - Add specializations for `map_parameters` because the auto-inference of the return type did not work for empty input.
        - Channels mapped to None are now dropped
    - Add simple arithmetic operations for pulse templates
        - offset and scaling with scalars
        - addition with atomic pulse templates

- Expressions:
    - Expressions can now be formatted as floats if they do not have free variables

- Parameters:
    - Replace Parameter class with Scope
    - Parameter class is now deprecated

- Backward incompatible changes:
    - Removed deprecated classes:
      - Sequencer: Replaced by PulseTemplate.create_program method
      - Condition: Never used
      - InstructionBlock: Old representation of programs. Replaced by Loop
      - MultiChannelProgram: Was required in the instruction block framework

## 0.4 ##

- General:
    - Add utility function `qupulse.utils.types.has_type_interface` and use it to circumvent autoreload triggered isinstance fails
    - Add utility function `qupulse.utils.time_from_fraction` to make creation from numerator and denominator obvious.

- Pulse Templates:
    - `MappingPulseTemplate`:
        - Raise a ValueError if more than one inner channel is mapped to the same outer channel
    - Plotting:
        - Make `plotting.render` behaviour and return value consistent between calls with `InstructionBlock` and `Loop`. Render now always returns 3 arguments.

## 0.3 ##

- General:
    - Introduce qupulse.utils.isclose (an alias for math.isclose if available)
    - Dropped support for Python 3.4 in setup.py due to incompatible syntax in qupulse.
    - Official support for Python 3.7 has begun.

- Pulse Templates:
    - `AtomicMultichannelPulseTemplate`:
        - Add duration keyword argument & example (see MultiChannelTemplates notebook)
        - Make duration equality check approximate (numeric tolerance)
    - Plotting:
        - Add `time_slice` keyword argument to render() and plot()
    - Add `AbstractPulseTemplate` class
    - `PointPulseTemplate`:
        - Fixed bug in integral evaluation
    - Add `ParallelConstantChannelPulseTemplate` which allows adding a constant valued channel to an arbitrary pulse template

- Expressions:
    - Make ExpressionScalar hashable
    - Fix bug that prevented evaluation of expressions containing some special functions (`erfc`, `factorial`, etc.)

- Parameters:
    - `ConstantParameter` now accepts a `Expression` without free variables as value (given as `Expression` or string)

## 0.2 ##

- General:

    - officially removed support for Python 3.3 (qupulse and dependencies are not compatible anymore)

- Serialization / Storage:

    - Added functionality to easily access available content/identifiers in `PulseStorage` and `StorageBackend`.
    - DEPRECATED `list_contents()` of `StorageBackend` (use `contents property` instead).
    - DEPRECATED: `CachingBackend` because its functionality is a subset of `PulseStorage`.

- Expressions:
    - Fixed bug in `Expression.evaluate_numeric` if result is array of numeric sympy objects

## 0.1.2 ##
