3.8.2 - Release Notes#

Squirro 3.8.2 was released July 12, 2023.

Reference: Learn more about the Squirro Release Process.

What’s New#

  • Squirro query syntax now supports multiple sort clauses, allowing you to add additional sorting clauses when two or more items match their primary sort criteria. See Multiple Sorting Criteria to learn more.

  • Introduced a new pipeline step called MIME Type Detection that identifies the MIME type of file-based items. This step can serve as a central way to detect MIME types in the pipeline, instead of replicating this logic in various dataloader plugins in cases where the MIME type is either not provided or is not trusted because it may be incorrect.

  • Enabled typeahead for PDF inline search inside the Item Detail modal.

  • Created the option to display only unique items within the Timeline and Metric widgets.

  • AutoML now supports Fasttext models.

  • Squirro now supports Speech to Text for the global search bar within Chrome browsers.

  • Squirro Docs now includes auto-generated Scoring Profile Plugin Reference documentation.


  • Disabled balancing dataset on AutoML templates to avoid downsampling.

  • Phrases are now highlighted in a more robust way (don’t split tokens).

  • Added weighted evaluation metrics to AutoML for imbalanced datasets.

  • Added config to enable/disable balancing of dataset inside balancer step. (#416)

  • Extended the default supported formats of the filesystem plugin to support ODT, ODP, ODS, CSV, and RTF file formats.

  • Added translate and compare tooltips to the ItemsWidget card.

Bug Fixes#

  • Fixed an issue with items within the pipeline editor not working properly because jQuery draggable was not available.

  • The React version of the Pie Chart widget now correctly supports the Rest slice and accompanying options.

  • Fixed an issue with yum remove squirro-tika-server failing because set -e was present.

  • Fixed an issue with the AutoML document classifier not labeling properly.

  • Fixed an issue with concept search not working in the CommunityItem widget.
