Release Notes

1.1.0

Change Log

  • Significant enhancements to the downsampling functionality. Users can now specify different downsample methods and parameters. Additionally, the application now retains the downsampling configuration between sessions.
  • To help provide provenance, datasets are now depreecated rather than deleted. This ensures that the ancestry of an expression is preserved. The catalog now provides a toggle to show or hide deprecated datasets, with an option to restore previously deprecated datasets.
  • Users can now force datasets into memory on the computation server to ensure the fastest possible analytics.

Known Limitations

  • Reverting an in-progress “applied” expression may not update the data table as expected when working with multiple tabs. Any changes to the expression, however, will be correctly applied.

1.0.1

Change Log

  • Lux datasets can be configured through the Mosaic interface. YAML configuration files are no longer necessary.
  • HDF5 files are now supported on Windows.
  • Expressions can now reference both ground truth datasets and derived expressions.
  • Completed changes to allow a dataset to have the same name as a column.
  • The coerce operation now operates as expected.
  • Improved downsampling controls are easier to use and allow the user to specify no downsampling for smaller datasets.
  • Resovled an issue that caused statistics from SQL datasets to not display correctly.
  • Fixed a problem that resulted in Firefox not loading the Mosiac page at startup.
  • To maintain provenance, dataset URIs are no longer editable.

1.0.0

Known Limitations

  • HDF5 on Windows is not currently supported due to issues with the underlying libraries.
  • To use a Lux dataset (flat file repository) you must configure a startup-up YMAL file. Please refer to the Lux tutorial.
  • An expression in Mosaic can only reference other ground truth datasets in the catalog, that is, an expression cannot reference another derived expression.
  • All datasets are automatically downsampled. Future releases will expost greater user control and flexibility of this feature.
