Depending on your installation type, additional action may be required. * **Kubernetes installations**: The upgrade to 2026.02 is seamless and managed automatically within the application container. * **Spark Standalone installations**: You must manually upgrade your underlying Spark environment to Spark 4.1.0 before upgrading to version 2026.02. This is a mandatory prerequisite. To learn how to upgrade Spark, go to [Upgrade Spark](/data-quality-self-hosted/installation/agent/upgrade-spark.md). {% endhint %} {% hint style="danger" %} Starting in Data Quality & Observability (self-hosted) 2026.03, all Data Quality & Observability (self-hosted) repo keys used to pull images for self-hosted Kubernetes installations will expire on April 30, 2026. You will need to update your workflows before this date to avoid disruptions.As of Data Quality & Observability (self-hosted) 2026.02, a self-service option to download temporary repo keys from the "Docker Images" section of the [Downloads page](https://productresources.collibra.com/downloads/data-quality-observability-classic-2026-02/) (login required) is available. Temporary repo keys are valid for 5 days from the download date. The process of requesting long-lived keys from Collibra Support will no longer be supported.To ensure deployment stability, we recommend using the temporary keys to download images, uploading them to your internal Artifactory or registry, and generating internal credentials for production deployments. There is no impact to self-hosted Spark Standalone installations. For instructions on pulling images from the Collibra registry, go to [Install on self-hosted Kubernetes](/data-quality-self-hosted/installation/installing-data-quality-observability-self-hosted-on-self-hosted-kubernetes/install-on-self-hosted-kubernetes.md) . {% endhint %} * The JobRunner version has been upgraded to 8.3.1. * The [Simba BigQuery JDBC driver](/data-quality-self-hosted/connections/supported-connections/supported-jdbc-data-sources/connecting-to-google-bigquery.md) is now updated to version 1.6.5.1002, and the Spark BigQuery connector is now updated to version 0.43.1. * The [Admin page for Webhook Alerts](/data-quality-self-hosted/admin-configuration/admin-console/alerts/alert-webhook-configuration/add-webhooks.md) now includes new columns for "Global" and "JSON Template." These additions allow you to view the full configuration of a webhook directly in the table, eliminating the need to open each webhook for editing. * A new security setting and user role are now available in the Findings module to provide granular control over data export capabilities. Administrators can restrict specific users from downloading or copying records to the clipboard while still allowing them to preview data in the UI. ### Jobs * You can now [archive duplicate break records](/data-quality-self-hosted/core-concepts/explorer/processing-methods/pushdown-processing.md) when using SQL Server Pushdown. * When you [rename a dataset](/data-quality-self-hosted/core-concepts/dataset-directory/dataset-manager.md) using Dataset Manager, you now receive a notification that the process might take some time. This ensures you're informed and prevents issues caused by refreshing or navigating away during the renaming process. * You can no longer select non-text rows when adding a "Shapes" layer during the [job creation process](/data-quality-self-hosted/core-concepts/explorer/create-a-dq-job/add-layers.md). This ensures compatibility, as non-text rows are not supported. * The Explorer SQL Query landing page now supports Common Table Expression (CTE) queries. CTE-based queries compile successfully and are no longer automatically escaped. Queries starting with the `WITH` keyword no longer require parentheses or additional whitespace around the CTE definition. * Known limitation: Pretty Print is not supported, and random characters entered in the SQL Query, such as "asdfasdfasf," returns an error message. * For S3 connections using an Instance Profile, missing or expired credentials now result in an explicit error when you access the connection from the Explorer tree. This helps you quickly identify and resolve credential issues. ### Findings * You can now add or edit a rule dimension from the "Edit Rule" dialog box on the Findings page. This provides more flexibility in managing rule dimensions. * The Source Export report now passes the label instead of the passStatus value to improve usability. This update improves usability by providing clear visual indicators for rule statuses: a green checkmark for "passing," a horizontal rule for a neutral state, and a red "X" icon for "failing." ### Rules * The preview behavior now correctly supports alias names with spaces and preserves the expected column order. Additionally, the Run Result Preview in the Rule Workbench now properly handles queries with aliases for pullup datasets. ### APIs * The /v2/putweights endpoint now accepts URL-encoded form parameters with the request type application/x-www-form-urlencoded. This enhancement ensures all current form parameters are handled correctly while maintaining the same response and behavior as the existing multipart implementation. Additionally, the server is no longer limited by maxPartCount for these requests. ## Fixes ### Platform * You can now edit remote file jobs and view columns without needing ROLE\_ADMIN or ROLE\_CONNECTION\_MANAGER privileges, as long as the environment's security settings don't explicitly require them. The URL parsing logic has been corrected to support this functionality. ### Jobs * When you delete a dataset with default dataset ownership enabled, other datasets that include the original dataset name are no longer removed from default owner access. This ensures that datasets remain accessible to their owners. * For complex queries, the correct schema and table name are now pulled from the query and placed in the metabar accurately. * You can now validate source mapping on columns that have spaces or special characters in their names. * The SCHEDULE\_ENABLED flag now properly disables the job scheduler. When the flag is set to FALSE, the scheduled jobs no longer run. ### Findings * You no longer encounter ORA-01830 syntax errors in Oracle datasets when using time-based outlier bins. Date strings with time components are now handled properly, ensuring accurate date formatting. ### Alerts * The Rule Details table in email alerts now correctly shows all rows for conditional alerts with multiple conditions connected by `and` or `or`. For example, multi-alert conditions such as `score > 75 AND find_valid_rules > 20` are now fully supported.
