+# Apache StreamPipes 0.98.0 Release
+
+Apache StreamPipes 0.98.0 is a major step forward in the evolution of the
platform, delivering **powerful dashboard
+enhancements, extended OPC UA capabilities, improved security and
authentication**, and a large set of **UX and
+architectural refinements**.
+
+This release focuses on consolidating visualization and dashboard
functionality, improving operational transparency, and
+modernizing the underlying architecture. Highlights include **dashboard
cloning and kiosk mode**, **new aggregation
+functions**, **enhanced OPC UA authentication and certificate handling**,
**file logging support**, and a **modernized
+UI**.
+
+In total, this release closes around 100 issues across enhancements, bug
fixes, and maintenance tasks.
+
+Read on to discover what’s new in StreamPipes 0.98.0!
+
+<!--truncate-->
+
+## Industrial Connectivity & OPC-UA
+
+### Redesign of the adapter creation page
+
+StreamPipes Connect is the central interface to connect a wide variety of
industrial protocols with Apache StreamPipes.
+In this release, a new overview page simplifies selection of appropriate
adapters, taking less space and allowing users
+to get a better overview over available connectors.
+
+<img src="/img/blog/2025-12-15/adapter-selection.png" alt="Excel export"/>
+
+### OPC UA X.509 Authentication & Certificate Management
+
+Support for OPC-UA security is greatly enhanced in 0.98.0.
+We added a new authentication option that supports **X.509 user
authentication**. Users can now directly upload their
+X.509 certificates which are securely stored within StreamPipes.
+
+For encrypted communication, we also added enterprise features to handle
OPC-UA certificates.
+Until now, certificates had to be managed through environment variables. In
the new release, server certificates can be
+**centrally managed** from the user interface, simplifying secure deployments.
+In case a non-trusted certificate is provided by the OPC-UA server, the
certificate is stored in the StreamPipes core
+for manual approval. In the settings menu, admins can explicitly trust or
reject a given certificate.
+The UI view also contains extended certificate information, making it easy to
get an overview of all OPC-UA certificates
+that are currently used.
+
+Version 0.98.0 also supports more OPC-UA data types such as better support of
**ExtensionObjects**, allowing more
+complex OPC-UA data structures to be processed.
+
+These improvements strengthen StreamPipes as a secure and enterprise-ready
IIoT integration platform.

+
+### Other improvements
+
+Minor improvements for other adapters include:
+
+- Configurable **wait and lease times** for PLC connectors.
+- Improved adapter state handling and recovery options.
+- Better schema guessing and duplicate field handling in OPC-UA adapters.
+
+## Dashboards & Data Explorer
+
+### Harmonized Data Explorer & Dashboard Experience
+
+The consolidation of visualization tools is finished in 0.98.0.
+The **Chart and Dashboard** views have been further harmonized, ensuring
consistent configuration and behavior.
+The deprecated dashboard has been removed and the new dashboard tool is fully
in place. Users can now add any chart
+directly to the live dashboard.
+
+This work lays the foundation for faster innovation and a more consistent
visualization experience going forward.
+
+### Dashboard Cloning & Kiosk Mode
+
+Dashboards have received further several long-awaited improvements:
+
+- **Dashboard cloning** allows users to quickly duplicate existing dashboards
and reuse configurations.
+- **Kiosk mode** enables distraction-free, full-screen dashboards—ideal for
shop floor displays and control rooms.
+- Improved configuration panel now clearly indicate missing or incomplete
dashboard and chart configurations.
+
+These enhancements significantly simplify dashboard reuse and deployment in
operational environments.
+
+### New Visualizations & Chart Improvements
+
+Several new visualization and charting capabilities were added:
+The **status heatmap visualization** was enhanced with a dedicated
color-mapping component, in the **chart appearance
+settings**, additional chart-specific configurations were added, including
improved heatmap configuration with
+customizable min/max values.
+To improve usability, icons and descriptions were added to the chart type
dropdown, making chart selection more
+intuitive.
+
+### New Aggregation Functions
+
+The chart view now supports additional aggregation functions:
+
+- **MEDIAN**
+- **SPREAD**
+- **STDDEV**
+
+These functions enable more advanced statistical analysis directly within
pipelines and the Chart view.
+
+### Excel export
+
+Besides CSV and JSON, datasets can now be directly exported to a Microsoft
Excel format (xlsx). In addition, Excel
+templates can be uploaded that can be used to add any company-specific header
data to an Excel export.
+
+<img src="/img/blog/2025-12-15/excel-export.png" alt="Excel export"/>
+
+## Security & Authentication
+
+Since we aim for enterprise-grade security, we added additional advanced
configuration options to integrate Apache
+StreamPipes with 3rd-party authentication providers.
+
+### OAuth & External Authentication Improvements
+
+Security and identity management received several upgrades.
+
+**External role assignment** is now supported in the OAuth configurations.
Besides default roles, users can now be
+assigned their roles directly from an external authentication service.
+To further increase flexibility, StreamPipes-internal roles and groups can be
assigned an **alternate ID**, which can be
+used to map external role names to StreamPipes roles and groups.
+
+**OAuth and OpenID configurations** are now loaded at startup time, so that
invalid settings are detected earlier upon
+startup.
+
+### User Management Enhancements
+
+User transparency was improved with:
+
+- Tracking and displaying **user creation date** and **last login date** in
the user configuration.
+- Optional **terms acknowledgment**, allowing organizations to enforce
acceptance of usage terms.
+
+## UX & UI Improvements
+
+### Modernized UI with Material 3
+
+The StreamPipes UI has been upgraded to **Material Design 3**, delivering a
cleaner, more modern look and feel.
+Additional UI improvements include:
+
+- Broader use of design tokens so that theming becomes easier for external
developers.
+- Panel resize components for flexible layouts.
+- Improved breadcrumb navigation in dashboards.
+
+### StreamPipes becomes multilingual
+
+Release 0.98.0 starts to add internationalization features to Apache
StreamPipes.
+While this will be a greater effort spanning multiple releases, this new
release lays the groundwork for a completely
+localized Apache StreamPipes experience.
+
+As a first feature, we've localized most parts of the UI to the german
language. More languages will follow in the
+future - if you are willing to help us translate StreamPipes to more
languages, let us know!
+
+
+<img src="/img/blog/2025-12-15/i18n.png" alt="Localized StreamPipes version in
German"/>
+
+### Actions menu
+
+To ensure a consistent design and a clean, streamlined look and feel, all data
tables across StreamPipes now use a
+unified actions menu. Instead of displaying multiple action buttons inline,
available actions are grouped under a
+three-dot menu. Simply hover over the icon to reveal the actions for a given
resource, making tables easier to scan
+while keeping all functionality readily accessible.
+
+<img src="/img/blog/2025-12-15/actions-menu.png" alt="New actions menu"/>
+
+## Developer experience
+
+### Migration to the New Data Processor API
+
+The migration to the **new Data Processor API** continues, improving
consistency and performance across pipeline
+elements.
+As part of this effort:
+
+- The legacy `StreamPipesDataProcessor` and `StreamPipesDataSink` APIs are now
**deprecated**.
+- The Flink-based wrapper has also been deprecated and will be removed in a
future release.
+
+Developers are encouraged to migrate to the new APIs to ensure long-term
compatibility.
+
+### Custom theming
+
+With the upgrade of the design system, we changed the way how the StreamPipes
UI can be customized with company-specific
+color settings.
+Settings that can be used for custom theming have been isolated in two files
(```_custom-variables.scss``` and ```_theme-colors.scss```).
+We encourage developers to investigate the modified prebuild script and the
two scss files to generate individual
+theming files.
+
+## Breaking Change
+
+### Default Messaging System Switched to NATS 💣
+
+The default `docker-compose` setup in the **installer directory** now uses
**NATS** instead of Apache Kafka for internal
+messaging.
+
+⚠️ **Important:**
+This change only affects users who are updating from a previous installation.
+If your existing StreamPipes instance uses Kafka, continue using the provided
`docker-compose.kafka.yml` file.
+
+## Deprecations ⚠️
+
+The following components and features are deprecated and scheduled for removal
in future versions:
+
+- Deprecated domain property APIs (use semantic type API)
+- Nested rule creation functionality
+- Legacy configurable data format APIs
+- Flink wrapper
+- IO-Link IFM adapter
+- NetIO adapter
+
+Users are encouraged to migrate early to avoid disruption in upcoming releases.
+
+## Other improvements
+
+As usual, StreamPipes 0.98.0 includes a variety of minor improvements, bug
fixes and dependency updates. Users are
+encouraged to update as soon as possible.
+
+## Conclusion
+
+Apache StreamPipes 0.98.0 delivers major improvements in **dashboarding, OPC
UA integration, security, and user
+experience**, while continuing the architectural cleanup and modernization
started in previous releases.
+
+We would like to thank all contributors and community members who made this
release possible.
+As always, we welcome your feedback—join the discussion on
[GitHub](https://github.com/apache/streampipes/discussions)
+or the [mailing list](mailto:[email protected]), and help shape the
future of StreamPipes!
