Releases from before GA are kept on the [legacy documentation site](https://docs.dataplatform.ovh.net/#/en/changelog). ## September 14, 2026 **General** - **Cookie consent:** cookie preferences now use the standard OVHcloud consent manager, reachable at any time from the cookie icon in the header. - **Fixes:** - permission checks for project creation are corrected. - a clearer error page is shown when your session cannot be verified. **Lakehouse Manager** - **[Row filters](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-row-filters.md):** restrict which rows of a table a user or group can see, without duplicating the table. The table keeps one copy of its data, and each person queries it through their own filters. - Write the condition in the default builder mode (column, operator, value, combined with _Match ALL (AND)_ or _Match ANY (OR)_), or switch to SQL mode for conditions the builder cannot express. - The impact panel reports how many rows the filter would keep and how many it would hide, before anyone is assigned to it. - Filters are enforced on Trino queries, so they cover Analytics Manager queries and dashboards and Trino consumers. A notebook reading through PySpark or PyIceberg, and direct storage access, are not filtered. - A filter can be saved inactive, switched on and off from the list, duplicated onto another table, and travels with a project configuration export. - **Fixes:** - deleting a project now also removes the dataset shares it granted, so a consumer project no longer lists a shared dataset whose source project is gone. **Data Processing Engine** - **Spark job memory:** Spark jobs now receive their full allotted memory, overhead included, which reduces out-of-memory failures. - **[Custom action](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-custom.md) logs:** `print()` and standard error output from action code now show up in the job logs, and a missing action produces a clearer error message. - **[Spark UI and History](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-spark-history-server.md):** Spark applications now carry the job's name instead of a generic one. - **Fixes:** - stopping a job now terminates its Spark application. - a job whose pod crashes is detected and reported instead of hanging. - running jobs are no longer archived out of the job history. - jobs that finish while you watch them now appear correctly in executed jobs, and pipeline stages display reliably. - Iceberg table procedures such as `expire_snapshots` and `remove_orphan_files` work again in PySpark jobs. **Analytics Manager** - **[SQL editor](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/analytics-manager-queries-sql-editor.md) autocomplete:** the editor now suggests SQL keywords, ready-made snippets, and every available Trino function with its description. - **Fixes:** - the runtime shown in the [query history](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/analytics-manager-history.md) is now formatted correctly. **Control Center** - **[Audit trail](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/control-center-auditing.md) search:** a new full-text search finds an event quickly, and the layout is clearer. **Apps and API** - **App resources:** each DPU allocated to an app now gives it 1 vCPU and 4 GB of RAM, matching the [DPU definition](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/manage-pricing.md#billing-units). Apps previously received half of that. The change applies on the app's next restart. - **Fixes:** - a build that gets stuck now reports why, with a status message and an event log. - two builds of the same app can no longer run at the same time. - an application again has exactly one active version. ## August 31, 2026 **Lakehouse Manager** - **[Views](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-views.md):** save a SQL `SELECT` query as a named virtual table inside a dataset and query it like a table, with results always computed live from the source tables. - Columns are derived automatically from the SQL, which is validated on every create and edit with human-readable errors. - Views track their own **Valid** or **Broken** status: they are re-checked automatically when a source table changes and recover on their own once the source is restored. - Policy tags, dataset permissions, and the audit trail apply to views just like to tables, and views created by external tools are discovered automatically. - **[Filtered tabs](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-tables.md#filtered-tabs):** filtered views in the Tables section are renamed to filtered tabs, to avoid confusion with the new views. **Data Processing Engine** - **[Deduplicate action](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-deduplicate.md):** new ready-to-use action to remove duplicate rows from a lakehouse or PostgreSQL table, keeping exactly one row per deduplication key. - The key is pre-filled from the table's identifier fields, a read-only scan previews how many rows a run would remove, and you choose which row survives (any, most recent, or oldest). - An optional backup table protects the run; on lakehouse tables a run can also be undone with Time Travel. - **Parallel job runs:** launching the same job several times in parallel is now safe: each run keeps its own data and results. - **[Spark History](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-spark-history-server.md):** the Spark application history is now reachable from older jobs too, not only the most recent ones. - **Fixes:** - when a job fails because a secret cannot be read, the actual cause is now shown instead of an opaque error. - the Rebuild action confirmation now shows the name of the table being rebuilt. ## August 24, 2026 **Lakehouse Manager** - **[Lineage](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-lineage.md):** a new built-in lineage view maps how data flows through your project, from the pipelines that feed each table down to the tables built from it. - Open it from the new **Lineage** section or straight from a table's details page, and drill down to column-level lineage. - Lineage now covers PySpark too: automatic for Load and Aggregate PySpark actions, opt-in through the [SDK](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/developers-python-sdk-lineage.md) for Custom PySpark actions and PySpark notebooks. - **Fixes:** - checkboxes in the Tables list view are now correctly aligned. - sharing a dataset with a consumer project that does not exist now returns a clear error instead of a storage engine failure. **Data Processing Engine** - **[Notebook export as a custom action](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-notebooks-data-platform-extension.md#export-a-notebook-as-a-custom-action):** the Data Platform extension can now turn a notebook into a custom action directly from JupyterLab, with the notebook's pip installs automatically converted into action dependencies. - **Fixes:** - environment variables already defined on a job are no longer overridden when the job starts. **Control Center** - **Fixes:** - job metric charts now display over any time range: the measurement precision adapts to the selected window instead of failing on wide ranges. ## August 3, 2026 **General** - **New guide:** [Trino data types and casts](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/tutorials-trino-types-and-casts.md), covering the mapping between Lakehouse types and Trino types and how to fix `TYPE_MISMATCH` errors when writing through Trino. - **Expanded docs:** deeper Lakehouse Manager pages on data types, naming rules, the storage model, and cross-project sharing, plus new Data Processing Engine docs on code sharing between actions, triggering notebooks from workflows, and CI/CD. **Lakehouse Manager** - **Fixes:** - sharing a dataset in read-only no longer downgrades the owner's own read-write access to that dataset. - the API now returns a 404 error instead of a 500 when a resource is missing or was deleted. **Data Processing Engine** - **[Data Platform Extension](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-notebooks-data-platform-extension.md):** a new JupyterLab extension adds a side panel to browse your project's datasets and storage buckets, run quick read-only SQL queries, and start from a gallery of ready-to-use notebooks wired to your own data. - **marimo extension:** the marimo notebook extension is now preinstalled in all notebook images. - Both extensions are new: try them out and share your feedback. - **[Custom action helpers](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-custom.md#use-the-helper-panel):** the helper panel in the Custom action and [Custom PySpark](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-custom-pyspark.md#use-the-helper-panel) editors now offers ready-to-use scenarios organized by category, SDK guides, a tab to browse your data, and a FAQ. **Control Center** - **[Audit trail](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/control-center-auditing.md):** new event types record configuration export and import operations. - **Fixes:** - job logs in the [Logs Explorer](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/control-center-logs-explorer.md) now display in the correct order without gaps or duplicated lines, streaming resumes after an interruption, and a loading error is shown instead of an empty log view. - the **Open logs** button now opens the Logs Explorer with the correct parameters instead of doing nothing. **Apps and API** - **Application scheduling (beta):** automatically start and stop an application (apps, APIs, Superset) during weekly activity windows, to avoid paying for idle time. - Pick a timezone and add one or more windows with days and start and stop times; outside these windows the application is stopped. - Transitions are evaluated about every 5 minutes, so a start or stop can be delayed by up to 5 minutes. - **In-memory caching (beta):** deploy a Valkey or Redis cache alongside an application service. - Choose the cache engine version and the share of DPU allocated to it (10 to 50%); the change takes effect after restarting the deployed version. - **SQLite backups (beta):** applications that store data in SQLite can now enable automatic backups. - Set the daily retention in days and how many weekly and monthly backups to keep, and open stored backups directly in the Lakehouse. ## July 20, 2026 **Lakehouse Manager** - **[Iceberg bucket](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-buckets.md#iceberg-bucket):** the Buckets screen now lists your project's Iceberg bucket, the storage behind your Lakehouse tables, in read-only mode. **Data Processing Engine** - **[Overview](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/landing-page-dpe.md) heatmap:** job activity is now grouped by day and 4-hour slot, with run counts shown per cell and only finished jobs counted. - **Build logs:** logs from the build phase of a job are now available, so errors during a build are visible and easier to debug. - **Notebook import and export:** notebooks are now imported and exported as ZIP archives. - **[Workflows](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-workflows.md):** a workflow must now contain at least one action to be started; empty workflows can no longer be run. ## July 6, 2026 **General** - **Configuration export and import:** each service module can now be imported directly from the UI, without calling an endpoint to import a configuration. **Lakehouse Manager** - **Fixes:** - **Explore snapshot** from Time Travel now redirects to the [Explorer](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-explorer.md) with the snapshot loaded. - searching a dataset by its full name (for example `default_dataset`) now returns the dataset instead of "You have no dataset". - deleting a shared dataset from a receiving project no longer leaves the Explorer without a dataset name. **Data Processing Engine** - **[Overview](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/landing-page-dpe.md) metrics:** new **Resource consumption**, **Top consumers**, and **Spark History Server** metrics, with a selectable last 7, 30, or 90 day range and faster loading. - **Fixes:** the [Rebuild action](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-rebuild.md) now mirrors an attribute's state when it is marked **Required + Identifier**. **Control Center** - **[Overview](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/landing-page-control-center.md) metrics:** new **Total resource consumption**, **Data scanned over time**, **DB storage (tables)**, and **Object storage (buckets)** metrics, shown both as current values and over time. - Metrics on the Overview and [Jobs Central](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/control-center-jobs-central.md) now load faster. - **Fixes:** - the [Alerts](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/landing-page-control-center-alerting.md) page now shows an error notification when alerts fail to load, instead of an empty "No alerts" state. - the [Audit trail](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/control-center-auditing.md) now loads further entries when paging past the cached results, at both project and organization level. ## June 22, 2026 **General** - **App Service component count:** the organization home now shows the number of deployed App Service components on each project box. - **New tutorial:** [Build an IoT fleet-monitoring pipeline](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/tutorials-iot-fleet-monitoring.md), an end-to-end guide streaming simulated sensor data from a Custom action through Kafka into a live Superset dashboard. **Connectors** - **Database connector pagination:** the database connector list is now paginated, making large lists easier to browse. - **Fixes:** sorting by column header now works on the Trino consumers table. **Lakehouse Manager** - **[Required and Identifier fields](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-manage-tables.md#attribute-constraints):** attributes can now be marked **Required** (never NULL) or **Required + Identifier** (part of the row's uniqueness key for upserts). - Required fields cannot be added once a table is built; use the new [Rebuild action](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-rebuild.md) to add them. Identifier fields cannot be `double` or `decimal`. - **Table metrics:** tables now have a **Metrics** section surfacing key statistics about the table. - **Fixes:** in the [Explorer](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-explorer.md), the **Export as CSV** button is disabled with an explanatory message when no query engine is active. **Data Processing Engine** - **[Write strategy](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-jobs-preferences.md#write-strategy):** Load and Aggregate actions (Python and PySpark) can now upsert using a table's identifier fields. - Choose **Upsert**, **Insert when not matched**, or **Insert all** in the action preferences. - Actions default to **Insert all**; select **Upsert** manually to enable matching behavior. - **[Rebuild action](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-rebuild.md):** rebuild a table from scratch to change field constraints, restructure partitioned data, and clean its metadata. - Set a default value when promoting a field to Required/Identifier; optionally keep a backup of the previous table. - Removes all table history; Time Travel is no longer available after a rebuild. - **[SQL action](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-sql.md):** write and run a SQL query against your datasets and tables on the Trino engine, as a schedulable, workflow-ready action. - Supports reads, metadata, DML, DDL, and `CREATE TABLE AS SELECT`, which also builds the new table in the Lakehouse Manager. - Validate before creating, with destructive-query confirmation and a re-validation check on every run. - **[Spark History Server](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-spark-history-server.md):** inspect the execution history of your PySpark actions and workflows from a new DPE page. - Start the server on demand to browse recent runs; it auto-stops when idle and is billed per DPU only while running. - Open each run's **Spark UI**, or analyze it with **DataFlint** performance insights, live or after completion. **Analytics Manager** - **Fixes:** in [Queries](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/analytics-manager-queries.md), the **Export as CSV** button is disabled with an explanatory message when no query engine is active. **Control Center** - **[Logs Explorer](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/control-center-logs-explorer.md) performance:** the Logs Explorer now issues a single metrics and jobs request instead of one per project, speeding up loading. - **[Alerting](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/landing-page-control-center-alerting.md):** the **Create alert** action is available again from the project homepage. - **Fixes:** - logs no longer display "Invalid date". - refreshing the [Auditing](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/control-center-auditing.md) trail no longer duplicates rows. **Apps and API** - **App Service UI (beta):** a redesigned, more unified interface for the App Service is now available as a beta, bringing it in line with the rest of the platform. - We will ship improvements and updates continuously over the coming weeks and months. Your feedback is welcome. - **Fixes:** creating an environment variable no longer fails with a 400 error. ## June 2, 2026 **Connectors** - **[Trino consumers](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/connectors-consumers-trino.md):** create a Trino connection string in a few clicks from the **Consumers** tab, instead of setting up a service account, API keys, and the connection string by hand. - Pick a **READ** or **READ & WRITE** access level per consumer. - The connection string appears only once, at creation; each consumer has a dedicated service account. ## May 25, 2026 **General** - **Contact Support:** the **Contact Support** link now opens an in-platform support form instead of redirecting to the external OVHcloud Help Centre. **Lakehouse Manager** - **[Cross-project dataset sharing](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-datasets.md#cross-project-sharing-beta) (beta):** datasets can now be shared read-only with other projects in the same organization. - Admins share from the source project via the dataset's **Configuration** tab → **Manage share settings** → pick one or more target projects. - Receiving projects see the dataset in their Lakehouse Manager **Datasets** menu with a shared icon and the type **Lakehouse Manager (shared)**. Tables can be previewed but not modified. - In the [Explorer](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/lakehouse-manager-explorer.md), shared tables appear under a new **Shared Datasets** category in the _list by dataset_ view. SQL editor only. **Data Processing Engine** - **Fixes:** importing a DPE configuration into another project now correctly rewrites repository references in workflows. Previously, workflows imported into the destination project still pointed to the source project's `repository_id` for the **Default** repository, breaking action references. **Control Center** - **[Auditing](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/control-center-auditing.md):** notebooks are now covered by the audit trail. ## May 5, 2026 **Connectors** - **New connectors:** - [HubSpot](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/connectors-sources-hubspot.md): extract contacts, companies, deals, tickets, pipelines, forms, marketing emails, and more. - [Odoo](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/connectors-sources-odoo.md): extract contacts, CRM leads, sales orders, invoices, products, inventory, HR, and projects from your Odoo ERP instance.

While active, the platform is read-only; run operations remain allowed. **Connectors** - **OpenLineage consumer:** - auth token is now optional. - new **Disable Trino events** toggle - skip Trino-generated lineage (Explorer, Analytics Manager) and forward only DPE batch lineage. - **Fixes:** schemas no longer displayed incorrectly in Marquez for forwarded lineage events. **Lakehouse Manager** - **Explorer:** - **Export to CSV:** scale fields now come before data fields in visual-query CSV exports (download and bucket export). - all non-numeric values are now quoted in CSV exports, which avoids parsing issues with commas, quotes and line breaks. - **Fixes:** **Preview table** now opens the Explorer with the selected table loaded. **Data Processing Engine** - **Git dependency auto-update:** [Custom](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-custom.md) and [Custom PySpark](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-custom-pyspark.md) actions now support `@latest` in Git-hosted Python dependencies: - Append `@latest` to any `git+` dependency URL to automatically resolve the most recent published release at build time. - Click **Force Build** to pick up a new version. No more manual tag or commit hash updates across actions. - Note: the latest release is not detected automatically at runtime, a manual **Force Build** is required to pull the update. - **Custom action lineage SDK:** new `lineage_run` context manager, auto-emits `START` / `COMPLETE` / `FAIL` and generates `run_id`. - **Custom action lineage helpers:** new `schema_facet` (declare schemas) and `column_lineage_facet` (column-to-column mappings). - **Auto schema detection:** pass `connector=` to `lineage_run` to extract schemas automatically. - Updated docs: [Track data lineage in a Custom action](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/developers-python-sdk-lineage.md). **Analytics Manager** - **Queries:** - **Export to CSV:** scale fields now come before data fields in visual-query CSV exports (download and bucket export). - all non-numeric values are now quoted in CSV exports, which avoids parsing issues with commas, quotes and line breaks. **Control Center** - **New: [Auditing](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/control-center-auditing.md) (initial release):** logs significant create / update / delete activity on the platform. Coverage will expand in upcoming releases. - Project-level view in Control Center; filter by service (Connectors, Lakehouse Manager, DPE, Analytics Manager, IAM), resource and time window. - Organization-level view in Organization Settings. Currently covers organization IAM and member management; billing, quotas and similar are coming soon. - Two new roles at each level: **Audit Trail Admin** and **Audit Trail Viewer**. - **Alerting (beta):** [alerting](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/landing-page-control-center-alerting.md) has been reworked and re-enabled. Please report any issues you run into. - **Fixes:** Logs Explorer now displays execution logs for DPE actions and workflows correctly. ## April 7, 2026 **Lakehouse Manager** - **OpenLineage compliance:** Data Platform now tracks and exposes data lineage events using the [OpenLineage](https://openlineage.io/) standard. Lineage events are recorded automatically for Load and Aggregate actions, and opt-in for Custom actions. - **Fixes:** Query Gateway now correctly auto-infers `catalog.schema` for Direct Query catalogs. This only affected tables with Direct Query enabled. **Connectors** - **New Consumer:** Added the [OpenLineage consumer](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/connectors-consumers-openlineage.md), connect your own OpenLineage-compatible lineage solution (e.g. Marquez) by providing an endpoint URL and auth token. **Data Processing Engine** - **New Action:** Added [Send OpenLineage Events](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/dpe-actions-send-openlineage-events.md), forward data lineage events from Data Platform to your external lineage backend. Supports cron scheduling or always-up continuous mode. - **SDK:** Added documentation for [tracking data lineage in Custom actions](https://docs.ovhcloud.com/en/guides/public-cloud/data-platform/developers-python-sdk-lineage.md) using the `emit_lineage` function.
