Released 28th October 2016

New Features

  • Painless prototyping: it's now possible to reset the search index, facets and dashboards via the API - great for when a new project is evolving. Details for use in the squirro python client are here under reset_project and the raw API documentation is here.
  • Pinpoint problems fast: the topic API log file now contains a new type of log message showing user requests and how long they took. Handy for debugging slow response times.
  • Flexible Facet Tables: the Facet Table widget gains an optional "detail view", offering new ways to present results to users. What's more, using the custom widget API, it's possible customise the look and feel to your requirements.


  • Smarter PowerPoint results: if your search matches content from a presentation, we now show you which slide was matched so you can quickly find your place in large presentations

  • Facet Lists the way you want them: the facet list widget now allows a custom sort of the order of facets, as an alternative to the default alphabetical sorting

  • Reduced dashboard noisiness: dashboards can now fold away facet lists just like on the standard search screen meaning less distraction for the eye from the results that matter

  • Faster Loading Results: static inline content like images is now served directly via nginx, reducing load times significantly

  • Keep and eye on trend training: the trend detection API response now includes a trends_healthy boolean value telling you whether the training, or re-training, of trend detection went successfully

  • You shall not pass! it's now possible disable new signups for installations where user access is fully managed via a different system.

  • Clearer error reporting: When user attempts to access an embedded dashboard but lacks security permission, we now return an HTTP 403 error

  • Cleaner Logs: the std*.log files are now rotated automatically by default and have been tuned to reduce verbosity and emphasise important messages

  • Fast Patching: project-specific changes and urgent updates can now be quickly and easily delivered via RPM without needing to upgrade to a new Squirro version

  • Bigger by default: the default number of Elasticsearch shards for new installations increases from 2 to 6 making it easier to handle larger datasets by default
  • Efficient loading of trends and smart filters: reduced the number of API calls required to load trend detection data as well as smart filters when "explain" mode is on

  • Migration to new Microsoft Bing API: To continue to use the bing provider you have to subscribe to the new microsoft cognitive service bing api and adjust your license key in the bing.ini configuration file. This improvement was added on the 23rd of November 2016.

API Changes

The dashboard format has changed. POSTing a dashboard with 2.4.3 format using the Squirro API will automatically convert the dashboard to 2.4.4 format.

How will this affect you? The 2.4.4 dashboards are not backward compatible anymore. It is not possible to convert a dashboard back to be usable with 2.4.3.

Fresh Installation Instructions

Please follow the regular installation steps.

Upgrade Instructions

To upgrade to version 2.4.4 of Squirro, please ensure that your current version is at least version 2.4.3 or higher. This is because of squirro rpm version number changes from "0.1" to "2.4.4". If you are on a version older than 2.4.3, please contact support.

Additionally if you are using Squirro in a Box, additional steps are involved. In this case we also ask you to contact support.
