  All related queries and visualizations have been updated on the **Data in Helmholtz**, **Repositories**, and **Assess my Data** pages.

* As evidenced by the issue ([#144](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/144)),

### Features update

* As evidenced by the issues ([#151](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/151), [#149](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/149)),
  the **text content and configuration files (YAML)** for all dashboard sections have been reviewed, standardized, and refined for clarity.

* As evidenced by the issue ([#141](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/141)),
  a **“How to Contribute”** section has been added to the main `README.md`, outlining best practices and contribution steps for open-source collaborators.

* As evidenced by the issue ([#155](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/155)),
  **averaging of FAIR scores** has been enhanced in the **sunburst plot**, providing a more accurate and balanced overall representation of FAIRness levels across datasets.

* As evidenced by the issue ([#129](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/129)),
  **numbers were removed from the list of centers** displayed on the welcome page, resulting in a cleaner and more accessible layout.

* As evidenced by the issue ([#134](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/134)),
  the **X (Twitter) icon** was replaced by the **Bluesky icon** to align with the current social media platforms used by the project.

* As evidenced by the issue ([#161](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/161)),
  the **Changelog page** has been updated to the documentation as well as in `CHANGELOG.md` file to provide users with a comprehensive overview of all changes, updates, and improvements made in version 3.0.0.

### Incompatible changes and deprecations

* As evidenced by the issues ([#154](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/154), [#162](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/162)),
  a complete **license compliance review** was conducted to ensure that all components are fully compatible with the **Apache 2.0 License**.
  Minor refactoring was required for some files and dependencies.

* The **database schema for the `fuji_score` table** has undergone a **significant redesign**.
  All F-UJI score results are now stored in a **single JSON field**, rather than in multiple column entries.
  These values are parsed dynamically at runtime within the dashboard for plotting and metric computation.
  This change improves performance and flexibility but **requires migration** of the previous table structure.

* The migration to **Dash 3** ([#144](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/144)) introduced **breaking changes** in the Bootstrap and Navbar components.
  Code adjustments were implemented to maintain functionality and layout consistency.

### Bug fixes and minor changes

* As evidenced by the issue ([#153](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/153)),
  fixed an issue where **empty data appeared for certain filter selections** on the *Repositories* page.

* As evidenced by the issue ([#155](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/155)),
  fixed a **bug in the averaging of FAIR scores**, which previously affected the overall representation in both the **sunburst plots** and the **FAIR score timeline plots** (evaluation over time).

* As evidenced by issues ([#135](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/135), [#136](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/136), [#114]),
  fixed a **license reuse bug** in banner images and fonts to comply with repository usage and attribution standards. Both **banner images and fonts were removed** to avoid this issue.

* As evidenced by the issue ([#148](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/148)),
  corrected an error in **v3.0.0-beta1** where **header links were not displayed**.

* As evidenced by the issue ([#80](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/hmc-fair-data-dashboard/-/issues/80)),
  discrepancies in **scoring consistency** between the dashboard and toolbox calculations were investigated and resolved.

  the **documentation for both the Dashboard and the Toolbox** has been fully updated for Version 3.0.

    "react-icons": "^5.5.0"
  }
  ```

  replacing the previous setup based on Next 14 / Nextra 2. These upgrades significantly **changed the documentation directory layout and build structure**.

* Introduced **version-switching options** in the documentation menu to allow readers to easily toggle between **the latest and older documentation versions**.

* Updated the [dashboard documentation](https://codebase.helmholtz.cloud/hmc/hmc-public/FAIR-dashboard/documentation/) to reflect:

  * Integration of [F-UJI metrics 0.8](https://doi.org/10.5281/zenodo.15045911) (including, in particular, the addition of metrics A1.1 and A1.2)
