Version 1.5.0

Released on 16.11.2023

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.

Version 1.4.1

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

Version 1.3.0

Released on 20.12.2022

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 “:raw-latex:`\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.

Version 1.2.0

Bugfixes

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

Version 1.1.0

Released on 25.07.2022

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.
