New nodes

Documentation

  • Documentation is built as part of the installation process. This means that documenatation should usually be available directly after installation.

  • Third-party library documentations can be built separately.

  • Documentation is now by default built for only the platform and the standard library.

  • Documentation pages are generated for library subflows. The subflows documentation can be edited in the subflow properties dialog.

  • Building the documentation places it in <SY_ROOT>/Docs/ by default.

  • Node documentation pages now start with the node’s description.

  • A warning is automatically added if a node is deprecated.

  • Nodes can now have a list of related nodes, which shows up on the node’s documentation page.

  • A node’s docstring is now used as description if the description field is missing or empty.

  • Basic node documentation for nodes with optional ports.

  • Updated documentation for available command line arguments.

API changes

News in 1.6.1

Release 1.6.1 is a bug-fix release addressing several bugs present in 1.6.0.

Platform changes

  • Write value and list to the syx file again for ParameterList. This change will have to wait until we have rooted out all nodes that use .value or .list of a list parameter.

  • Made it possible to open workflow with reference to missing library.

  • Made it possible to open tabbed subflow configurations containing failed configurations.

Node changes

  • Changes in Figure:

    • Add property ‘Distance to Axes’ to legend. Use this to tweak the position of the legend when placed outside of the Axes. If the legend is placed inside the Axes this property is ignored.

    • Avoid rare exception when editing some properties.

    • Improved default values and editors for Annotations.

  • Changes in Figure Compressor and Layout Figures in Subplots:

    • Fixed a bug when copying axes with unsupported elements. Those elements will now simply be ignored.

  • Fixed inability to configure and execute Calculator Table(s) if comment contained newlines.

  • Introduced compatibility option for Select rows in Table(s).

  • Fixed issues with configuration related to missing list and value in:

  • Fixed issues with preview/viewer on Windows for:

  • Fixed issue in JSON to Table (deprecated).

  • Fixed use of Fit/Fit Transform with One-Hot Encoder.
