Migration notes

How to upgrade

Pay attention to the warnings described in Limitations and warnings.

Migration paths to DSS 14

Limitations and warnings

Automatic migration from previous versions is supported (see above). Please pay attention to the following cautions, removal and deprecation notices.

Cautions

Dataiku Cloud Stacks: OS upgrade

For Cloud Stacks setups, the OS for the DSS nodes has been updated from AlmaLinux 8 to AlmaLinux 9.

Custom setup actions may require some updates

Cgroups have moved from V1 to V2. Most configurations (including the out-of-the-box configuration) are migrated automatically. Some specific configurations may require a manual update.

Dataiku Cloud Stacks: Removal of old Python versions

Cloud Stacks setup do not include Python 3.6, Python 3.7 nor Python 3.8 anymore by default. All these Python versions are deprecated, and we advise you to upgrade remaining code still using them.

If you need to maintain support for one of these Python versions, setup actions have been added to reinstall these versions, and can be configured in your Instance Template in Fleet Manager.

Container images: OS upgrade

The OS for container images has been updated from AlmaLinux 8 to AlmaLinux 9. Custom Dockerfile additions may require some updates (either if you build customized base images, or when using custom “container additions” in code envs)

Prebuilt container images: Removal of old Python versions

The Dataiku prebuilt container images do not include Python 3.6, Python 3.7 nor Python 3.8 anymore by default. All these Python versions are deprecated, and we advise you to upgrade remaining code still using them.

However, at the level of each code env, a “Container runtime addition” has been added to easily re-add, on a per-code-env basis, support for them.

On Dataiku Cloud Stacks, these container runtime additions are automatically added to existing code envs running one of these Python versions.

Dataiku Custom: Bump of minimal Java version

Dataiku now requires Java 17.

No action is required on Dataiku Cloud Stacks and Dataiku Cloud. On Dataiku Custom, you may need to install Java 17 prior to upgrading to Dataiku 14.

Support removal

Some features that were previously announced as deprecated are now removed or unsupported.

  • Support for R 3.6

  • Support for MLFlow < 2

  • Support for Python 3.6 and 3.7 for the builtin environment. Builtin environments using these versions will be automatically upgraded. Note that code envs can still use Python 3.6 to 3.8 but these are deprecated

  • Support for Java 11

  • Support for Red Hat Enterprise Linux 7.x

  • Support for CentOS 7.x

  • Support for Oracle Linux 7.x

  • Support for Debian 10.x

  • Support for Ubuntu 18.04

  • Support for SuSE 15 SP4 and below

In addition, the following plugins have been removed and cannot be used anymore with DSS 14:

Deprecation notices

DSS 14 deprecates support for some features and versions. Support for these will be removed in a later release.

  • Support for Python 3.8. As a reminder, Python 3.6 and 3.7 are already deprecated.

  • Govern: Support for PostgreSQL 12, 13 and 14

  • Time Series Forecasting: support for MXNet-based algorithms

Version 14.0.0 - June 27th, 2025

DSS 14.0.0 is a major upgrade to DSS with major new features.

New feature: New home page

A completely new home page for Dataiku has been introduced.

The home page brings together your projects, your recent items, learning content from Dataiku as well as content from your administrator in a refreshed and modern interface.

The projects listing has been upgraded with new capabilities such as easier moving of projects, a table view for quick mass operations on projects, a tree view for better organization of your projects, and better search across projects.

The data catalog is now directly accessible within the home page for more efficient exploration of your data.

New feature: Dashboards and Charts Theming

The platform now supports the use of reusable themes to enhance the visual presentation of charts and dashboards. These themes facilitate the standardization of colors, fonts, and design elements, thereby ensuring a professional and branded aesthetic. This functionality allows users to establish a consistent visual identity across their visualization assets, effectively reflecting their organization’s branding.

New feature: Automatic throttling for LLM connections

A new system has been added for automatically throttling requests to LLM API providers. This gives you finer and simpler control over the speed at which requests are issued, to better handle cases where you only have limited quotas on your LLM provider.

For more details, please see Rate Limiting

New feature: Enhanced documents embedding

The Embed Documents recipe can now embed PDF, DOCX, PPTX and more using text-only extraction. This does not use a Vision LLM, and is faster and cheaper when the documents do not need a visual interpretation. Note that this requires using a new internal code env (“Document extraction”), which needs to be set up.

The Embed Documents can now avoid re-processing documents you’ve already processed with the new Smart Sync, Upsert and Append modes.

The Embed Documents recipe is now faster, even when using visual extraction

New feature: AI-Assisted Metadata & Metadata synchronization

A new (optional) AI Assistant now helps you generate dataset metadata and column descriptions.

On SQL datasets, table and column descriptions can now be automatically synchronized to the underlying SQL table. This is enabled by default on Snowflake, Databricks, BigQuery and MySQL.

New feature: Deployment Alerts

In Unified Monitoring, administrators can now configure alerts for Project and API Endpoint deployment statuses, with notifications deliverable via various channels

New feature: Model evaluation for Time Series forecasting

Dataiku now integrates its Model Evaluation capabilities with time series forecasting models. This enhancement allows you to visualize the evolution of key metrics, set custom alert thresholds—including per-identifier thresholds via code—and detect performance drift over time. Delve into detailed comparisons of forecasts versus actuals, pinpoint problematic identifiers, and gain deeper insights into your model’s behavior.
