4D 21 R2 Beta Starts Today

Upload and Use Files in AI Conversations

4D AIKit now supports native file uploads. Use OpenAI.files.create() to upload documents and attach them to messages so the AI works directly with the original file. Summaries, questions, and analysis stay grounded in the source document, with explicit lifecycle control and no preprocessing.

Vector Based Ordering in Queries

Queries can now order results by vector similarity. When a vector field is used in both the filter and the order by clause, the same similarity calculation determines relevance and ranking. The query itself expresses what matters most, and results come back already ordered by meaning.

QODLY PAGES ACCESSIBLE FROM THE 4D IDE

Create and edit Qodly Pages directly from the 4D Explorer. Pages live alongside the rest of the project, and opening them launches Qodly Studio immediately, keeping backend and web UI workflows connected.

FLUENT UI RENDERING FOR 4D FORMS (DEVELOPER PREVIEW)

4D forms can now be rendered using the Fluent UI design system on Windows, as a Developer Preview. Enable it globally or per form to adopt a modern Windows look with native light and dark mode support. Existing forms keep their logic and structure, while deployment remains predictable with automatic fallback to classic rendering.

UNIFIED SYNTAX CHECKING AND CODE COMPLETION

Syntax checking and IntelliSense now share the same inference logic across the 4D IDE and VS Code. Errors are underlined precisely where they occur, types are inferred consistently, and editor feedback becomes reliable instead of noisy.

AUTOMATIC INDENTATION FOR BULLETED LISTS

Bulleted and numbered lists created using standard actions are now automatically indented. Lists align correctly inside the page without manual margin adjustments, and removing bullets restores the original layout. Formatting stays predictable, even in multilingual documents.

FIND IN DESIGN ACROSS COMPONENTS

Find in Design now searches across the host project and all accessible components. Results clearly indicate their origin, and exports preserve project and component context for refactoring and audits.

CUSTOM ICONS FOR COMPONENT DEPENDENCIES

Components can now display custom icons in the Component Manager. A simple logo file gives each dependency a visual identity, making large dependency lists easier to scan.

SPREADJS ENGINE UPDATED TO 18.2

4D View Pro now runs on SpreadJS 18.2, improving performance, reducing memory usage, and unlocking new PivotTable, calculation, and import/export capabilities, without changing existing documents.
