• Line has trailing whitespace at the end, which commonly fails text/markdown linting and creates noisy diffs.

Our new AI master-detail feature will also display generated content in a format better suited to longer, more in-depth insights. The capability will include a prompt-driven data analysis UI within DataGrid master-detail interfaces, spanning the full width of the component.

• This markdown file has trailing whitespace at the end of lines, which commonly fails text/markdown linting and creates noisy diffs.

This issue also appears on line 6 of the same file.

We plan to integrate AI-driven data exploration into the [DataGrid](https://js.devexpress.com/Documentation/Guide/UI_Components/DataGrid/Overview/)'s master-detail scenario. This new functionality allows users to analyze individual record data using natural language. 

In v25.2, we released the [AI column capability](https://www.devexpress.com/subscriptions/new-2025-2.xml#js-grids-ai-columns) for DataGrid. This feature introduced the ability to extend component data using an AI prompt. However, certain usage scenarios do not require generated data for every row. Instead, users may need on-demand data generation for specific rows. Our new AI detail scenario will offer this capability, which can significantly reduce AI token consumption and enhance data generation performance. 

apps/demos/Demos/Map/OpenStreetMapProvider/description.md:1

• Other Map demo descriptions include a <!--split--> marker to separate preview text from the full description (e.g., Demos/Map/Markers/description.md:4, Demos/Map/Routes/description.md:4, Demos/Map/ProvidersAndTypes/description.md:6). This new description is missing it, which may affect how the demos site splits/preview-renders the text.

We plan to introduce [OpenStreetMap](https://www.openstreetmap.org/) (OSM) support in the DevExtreme Map component. The new provider will allow you to connect the Map to OSM-compatible tile, geocoding, and routing services, including commercial providers and self-hosted infrastructure.

• Line has trailing whitespace at the end of the sentence. This can trigger text/markdown linters and creates noisy diffs when edited later.
