Reference: Learn more about the [Squirro Release Process](../../squirro-release-process.md#getting-squirro-process). ## What’s New - Squirro now supports license keys for easier provisioning and updating of Squirro features and metrics. - Added a mechanism to the ingester service to restart the local Apache Tika service in case of internal server errors. This mechanism is controlled by the server config option `ingester.tika.restart-on-error-*`. - You can now change boolean operator chip values (`AND`, `OR`, `NOT`) by clicking on them and selecting from the dropdown.
