Released 3rd May 2017

New Features

Connecting to your data just got even easier: Data Loader Plugins - previously only available for use on the command line, can now be configured and used online from your Squirro installation. Just point and click...
More Query Power: you can now use wildcards in Squirro facetted queries for example;
- "company:*" ... match all items that have the company facet set
- "-company:*" ... match all items where it's missing
- "name:Jane*" match all items where facet "name" has a value that start with "Jane"
- For further details see the Query Syntax documentation
Steve, Steven or Stevie? It's all the same to us - we added support for synonyms allowing you to connect specific search terms which related to the same concept. Currently available via the Squirro REST API and Python SDK. Further details coming soon

Improvements

Smarter Memory Use: we split off the Redis cache database from the rest of the the Redis databases, allowing us to use it's LRU caching capabilities, which will typically mean less memory usage overall. Worth noting is the documentation on flushing caches...
Faster Service Restart: we optimised how Squirro services shutdown so less waiting around when restart Squirro or the server it is running on
Catch Up with Facebook: the Facebook data provide now supports the latest version of Facebooks Graph API
Flexible Tables: custom cell and header templates for Table widget
