Sympathy for Data v1.1.2 available!

Highlights

Sympathy for Data version 1.1 is a significant minor release for Sympathy for Data. Since version 1.0 was released almost one year ago, the application has been rewritten entirely in Python. It is however not redesigned and with a few exceptions, all existing nodes and flows should work out of the box.

This maintenance release 1.1.2 improves on 1.1.1 with improved API documentation, several minor fixes and improved overall stability. The release also includes a new system for raising warnings and exceptions in nodes. A regression affecting many nodes caused by an overzealous length check was fixed.

Fixed Bugs Compared To v1.1.1

The following issues have been fixed:

    • Relaxed overzealous column length checks in sytable
    • Raise IndexError in case of out of bounds integer indices in sytable.getitem.
  • Library fixes
    • Fixed handling of encoded attributes in LAA importer.
    • Always coercing header to unicode in LAA importer.
    • Fixed potential unicode problems in MDF and sydata exporters and importers.
    • Fixed a case where unit and description could become numeric values in csv/xls/xlsx importers.
    • Fixed lost table name in select table rows nodes.
    • Fixed incorrect uses of ADAF source_id in standard library.

  • Interface
    • Copy/cut from context menu now works for subflows too.
    • Fixed a problem when when creating a subflow with input port from selection.
