Other

None

Release v1.6.0

Breaking Changes

None

Bugfixes

• Fixed a bug with the qtconsole package no longer being part of jupyter. It is now listed
  explicitly in the dependencies.
• Fixed SystemTrayIcon error when activating GUI modules

New Features

None

Other

• Removed setup.py and moved fully to pyproject.toml instead

Release v1.5.1

Breaking Changes

None

Bugfixes

• Fixed deprecated import path for windows module from scipy.signal in qudi.util.math
• Fixed decay parameter estimation in qudi.util.fit_models.exp_decay.ExponentialDecay fit model
• Fixed syntax error in qudi.util.fit_models.lorentzian.LorentzianLinear fit model

New Features

None

Other

• Improved documentation getting_started.md
• Added documentation programming_guidelines/data_fitting_integration.md

Release v1.5.0

Breaking Changes

None

Bugfixes

• Fixes a bug where all fit configurations for a fit model/container fail to load upon activation
  of a module because the fit model saved in AppData is no longer available. Throws a warning now
  instead and ignores the respective fit configuration.
• Fixed a bug that caused qudi.util.models.DictTableModel to raise IndexError when used in a
  ListView and/or when data at index zero is requested.

New Features

• Added helper functions in util/linear_transform.py to allow transformations (rotations and shifts) using the affine transformation matrix formalism.

Other

• Fine-tuning of string output of fit results from qudi.util.units.create_formatted_output(): Failed fits should provide
  error= np.nan. Fixed parameters are marked as such. Brackets introduced, eg. (2.67 ± 0.01) GHz.

Release v1.4.1

Breaking Changes

None

Bugfixes

None

New Features

• Added utility descriptor objects to new module qudi.util.descriptors. Can be used to
  facilitate smart instance attribute handling.

Other

• Support for Python 3.10
• Better backwards compatibility of qudi.util.constraints.ScalarConstraint with the deprecated
  qudi.core.interface.ScalarConstraint object

Release v1.3.0

Breaking Changes

None

Bugfixes

• NULL bytes in log messages are handled now and no longer lead to crashes of qudi. They are
  replaced by the corresponding hex literal "\x00".
• Rubberband selection of utility plot widgets now works for pyqtgraph != 0.12.4. This specific
  version is broken in that regard and a comprehensive error is thrown if it is detected.
• Adjusted 2D gaussian fit arguments to be compatible with the datafitting toolchain.

New Features

• Multiple qudi sessions can now be run in parallel locally. However, the user must ensure
  non-conflicting socket server settings for namespace server and remote module server in the
  configs to load.

Other

• Bumped minimum package requirement pyqtgraph >= 0.13.0.
• Introduced properties to make qudi.util.constraints.ScalarConstraint mostly backwards
  compatible with the deprecated qudi.core.interface.ScalarConstraint. Only exception is unit
  which should not be supported anymore.

Release v1.2.0

Breaking Changes

None

Bugfixes

None

New Features

• New general-purpose interactive data display widget
  qudi.util.widgets.plotting.interactive_curve.InteractiveCurvesWidget providing multiple optional
  features:
  • Legend creation and generic dataset naming
  • Linking of fit curve to dataset and synchronous handling of both
  • Rubberband zooming in 1 and 2 dimensions
  • Data markers in 1 and 2 dimensions
  • Data range selections in 1 and 2 dimensions
  • Checkbox-based toggling of dataset visibility
  • Plot editor for setting axis labels, units and view ranges
  • Mouse cursor tracking and display in data coordinates
  • Various signals to interface with the above-mentioned features

Other

None

Release v1.1.0

Breaking Changes

• Changed event handling of qudi module state machine. on_deactivate will be run BEFORE the state
  machine actually changes into state deactivated.
• ConfigOption meta-attributes of qudi modules are no longer set in config under the module name
  section directly, but must be specified in an options subsection instead.
  So something like

  my_module_name:
      module.Class: 'qudi.hardware.my_module.MyModule'
      first_option: 42
      second_option: 'hello world'

  must become now

  my_module_name:
      module.Class: 'qudi.hardware.my_module.MyModule'
      options:
          first_option: 42
          second_option: 'hello world'

Bugfixes

• Qudi logging facility active during startup procedure
• Reduced RPyC related errors in qudi IPython kernel

New Features

• Support for enum.Enum types in qudi.util.yaml, enabling use of enums in qudi config and
  status variables.
• qudi.util.constraints.ScalarConstraint data class to easily define bounds for, check and clip
  scalar values.
• Added qudi logger object to qudi IPython kernels to give users the possibility to directly log
  messages into qudi from e.g. a jupyter notebook.

Other

• Structure and type checking as well as default value handling in the qudi configuration file is
  now done via JSON Schema (Draft-07). The applied schema is defined in qudi.core.config.schema.
  Every time you load/dump a configuration from/to file or add/remove a module config or set a global
  config option using qudi.core.config.Configuration, the config is validated against this JSON
  schema.

Release v1.0.1

• Enabled Qt5 support for high DPI displays
• Got rid of .png icons, using .svg/.svgz source files instead
• Added support for Python 3.9 as last supported Python version of PySide2. Any further Python upgrades require a port to PySide6.
• Added PyPI metadata
• Better installation instructions

Release v1.0.0

This is the initial release of qudi as a proper Python namespace package.
