# 3.4.6 Release Notes ## Breaking Changes - [Squirro 3.4.5](squirro-3.4.5-release-notes.md#release-notes-3-4-5) introduced a configurable Query-Processing pipeline and automatically installed a default workflow on newly created projects. Now with 3.4.6 the auto-wiring of the default query-processing workflow is disabled because it failed to handle some operations correctly as defined in the official Squirro Query Syntax (COMPARISON operator). If you are affected by unexpected query-behaviour, simply disable query-processing in the Project-Configuration > `topic.search.query-workflow` (remove the workflow ID). The automatic workflow creation for new projects is now set to be OPT-IN (Server Setting > `topic.search.setup-default-query-workflow` set to False). The default-workflow feature will be re-enabled in the next releast. ## Features - QueryPipeline Example: Showcase how to customise SpaCy’s Tokeniser to not split Terms by Hyphen _-_ or Slash _/_ characters. This will force SpaCy to keep _new-york_ or _AC/DC_ as one single token and help to create more precise queries. - The size of the rerun from index batches is now configurable via the `datasource.rerun.index.batch-size` configuration option (through the Configuration Service). - SAML plugin now shows the correct error message if the user doesn’t have required role while logging in through SSO. - SpacyNormalizer: Added a new _Phrase Matcher_ - If used, it can automatically merge terms in quotes into one single token (_config.merge_phrases_). ## Bug Fixes - Fixed the `Scroll to top` action in the Item Detail view. - Fixed the missing `Scroll more` button in the ItemListCards. - Enabled AI Studio components cleanup and ML workflow removal during project deletion. - [AI Studio] Fixed improper buttons that were shown in the candidate set. - [Spellchecking Widget] Fixed a bug where the suggestion was not clickable anymore. - Changed the workflow name for the workflow associated with a published AIS model. - Exporting and importing of AI studio models now also correctly exports all the relevant models & jobs next to Machine Learning Workflows. - Fixed a rare bug where editing a custom widget could break the widget - Query Processing / ML-Workflow Studio plugin: (Active Processing Workflow button) Now handles the case when a project does not use an active workflow for query-processing. - Fixed various bugs around the batch creation of communities. - Fixed text hiding the remove icon when it is too long in the reset filter widget. ## Installation and Upgrade You will have to resolve at least the following config files when upgrading from Squirro 3.3.0 - `/etc/nginx/conf.d/ssl.inc` - `/etc/squirro/common.ini` For new installations, please follow the [Installing Squirro on Linux](../../../install/linux.md#install-linux) instructions.
