# 3.8.3 - Release Notes Squirro 3.8.3 was released July 24, 2023. Reference: Learn more about the [Squirro Release Process](../../squirro-release-process.md#getting-squirro-process). ## What’s New - Introduced the beta feature _Hybrid Search_, which retrieves results based on semantic/vector processes and keywords. This feature was created by adding the scoring profile `semantic`, allowing users to perform approximate vector searches on paragraph embeddings. Note that this feature is currently in beta, and the pipelet and the semantic search components only work if a separate model is available (which is not the case for current Squirro out-of-the-box deployments). For more information, see [Scoring Plugins](../../../../technical/search/relevancy/scoring-plugins/index.md#search-scoring-plugins). - Added the scoring profile `extractive-qa`. This highlights the answer to a query within the top-ranked paragraphs. - Added the scoring profile `cross-encoder`. This allows for top-N paragraph reranking based on contextualized similarity of `query and paragraph`. - PDF inline search, which appears within the item detail screen, now uses the same query processing as global search. This significantly improves search quality inside the item detail scren and allows for future improvements on the backend. - Added `query` to community subscriptions collection, allowing for community subscription filtering via query. This is currently available in the Items Table widget. - Admins can now access query-processing results in dashboard query templates using the `queryContext` variable. - Introduced a new pipeline step called _Archive Extraction_ that extracts archive files. At the moment only ZIP files are supported. Each file in the archive becomes an individual item, and the archive itself is removed. - Created a new index manager service for Elasticsearch maintenance. ## Improvements - If pasting text into the global search bar is long enough to trigger concept search, Squirro will check now check for filters. If there are more than two found then concept search is not triggered and the search string is treated as a complex query. - ItemDetail will now include additional widget queries from ItemsWidget and use it for highlights. - Added `query_template_clause`, also known as _ACL handling_, to the entities query endpoint. - The QA widget configuration within project configuration is now displayed in a user-friendly way. - Reset SELinux content from `unconfined_u` to `system_u` for the `/var/{lib,log,run}/redis` folders. - The connectors for Dropbox, Google Drive, and OneDrive have been moved from the _Enterprise_ tab to the _Web_ tab for better discoverability. - Added special facets to the _Items Table_ widget - It is now possible to hide the sort options from Items widget. ## Bug Fixes - Fixed an issue with CommunitiesList widget not reacting to global search being cleared. - Fixed missing body content in document bulk labelling within AI Studio. - Fixed an issue with the _Timeline_ widget not displaying on the Explore dashboard. - Fixed several issues relating to how multiple Items widgets interact on the same dashboard. - Fixed an issue that occurred when, in some cases, Item detail opened multiple times when multiple Items widgets were present in a dashboard. - Fixed ItemsWidget infinite loading loop if the widget had an additional query in the configuration. - Fixed an issue with missing global search queries in the requests from the _Labels_ widget. - Fixed an issue with original global search queries in query visibility conditions. ## Breaking Changes - The `perform_on_languages` option in the QA widget configuration no longer supports the `None` value. To find an answer regardless of the language of the question, set this option to `*`. - The `terminate_after` option in the content typeahead configuration no longer supports boolean values. To stop query execution from terminating early, set this option to `0`. ## Installation and Upgrade For new installations, find step-by-step instructions in [Install and Manage Squirro with Ansible](../../../install/ansible/index.md#ansible) (recommended) or [Installing Squirro on Linux](../../../install/linux.md#install-linux).
