## Features * **Generic and nested widget grouping**: Added support for generic and fully nested widget grouping using the [dynamic group](/app-builder/build-frontend/widgets/dynamic-group.md) widget. * **Data binding to groups**: Enabled high-level data binding for widget groups in the [dynamic group](/app-builder/build-frontend/widgets/dynamic-group.md#data-settings-data-bindings) configuration. * **Introduced the** [**card**](/app-builder/build-frontend/widgets/display-widgets/card.md) **widget**: Display visually grouped components dynamically inside your Apps. * **Multi-state** [**status lamp**](/app-builder/build-frontend/widgets/display-widgets/status-lamp.md): Improved the status lamp widget to support multiple states and a rectangular shape. * **Configurable backgrounds for icons**: Improved the icon component in [Text, icons and images](/app-builder/build-frontend/text-icons-and-images.md) to support optional background shapes. * **Runtime properties**: Added support for configuring multiple new properties at runtime across various [widgets](/app-builder/build-frontend/widgets.md). * **Database audit logging**: Added database audit logging to the [relational database](/app-builder/build-backend/functions/storage/relational-database.md#audit-logging) connector. * **Machine simulator option**: Added the machine simulator option to the [Process Simulations](/app-builder/build-backend/functions/extensions/process-simulations.md) extension. * **AI assistant (beta)**: Released the first experimental version of the AI assistant. * **Experimental subflows**: Released the first experimental support for [subflows](/app-builder/build-backend/functions/subflows.md). ## Improvements * **UI interaction and performance**: Optimized user interface interactions and platform performance across the workspace. * **Codebase health**: Cleaned up and consolidated the internal widget rendering factory. ## Fixes * **On-premise system restarts**: Fixed system start behaviors to reliably restore [on-premise installations](/tutorials/on-premise-installation.md) after a power cycle. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.heisenware.com/release-notes/v90-grouped-periodically.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
