# 3.16.0 Release Notes Squirro 3.16.0 was released on May 28, 2026. Learn more about the [Squirro Release Process](../squirro-release-process.md#getting-squirro-process) page. > **Notes for administrators** > > Oracle Database is no longer supported by Squirro as of version 3.16.0. Squirro strongly recommends migrating to PostgreSQL. For guidance on migration options, visit the [Squirro Support website](https://go.squirro.com/support) and submit a technical support request. ## Improvements ### AI - AWS Bedrock Guardrails configurable via `genai.sqgpt.settings` using the `guardrail_config` parameter on Bedrock chat model settings. ### Platform - Elasticsearch, Filebeat, and OpenSearch upgraded for improved performance and security. - Faster responses on dashboard queries that use only facet filters. Language detection is skipped when a query contains no natural-language terms, avoiding an unnecessary call to the search engine. ## Bug Fixes - Content conversion failing for files saved with non-standard character encoding. - Ingester batches occasionally dropped during retry when the queue folder was removed before items could be moved in. - Dataloader log rotation not working on systems with SELinux in enforcing mode. - Long documents failing to index with a `ParagraphIndexOperationError` when using a Semantic Search pipeline or a pipeline that includes the Paragraph Embedding step. - Paragraph index updates timing out on large documents. ## Known Issues - In specific scenarios, cross-lingual information retrieval for semantic search may deliver lower-than-expected quality (SQ-28171). ## Installation and Upgrade For new installations, find step-by-step instructions on the [Install and Manage Squirro with Ansible](../../install/ansible/index.md#ansible) page (recommended) and [Installing Squirro on Linux](../../install/linux.md#install-linux) pages.
