4D 20 R10 Beta Starts Today

NEW 4D.VECTOR native class

Use 4D.Vector to store, compare, and manipulate high-dimensional numeric data directly in your app. Perfect for semantic search, intelligent ranking, or document classification—no external dependencies required.

Vector Generation via OpenAI in AI Kit

The AI Kit now supports OpenAI’s vector API. The OpenAIEmbeddingsAPI.create() method lets you convert text or collections into typed vectors for similarity scoring, search filters, and recommendation engines—natively and securely.

CLASS-TYPED OBJECT FIELDS IN STRUCTURE EDITOR

Assign object fields to specific classes to unlock compile-time autocompletion, runtime validation, and schema-based data integrity. Pair with 4D.Vector to store AI-ready fingerprints on each entity.

SUPPORT FOR V7 UUIDS

Generate v7 UUIDs using UUID.generate()—ideal for distributed systems, time-based indexing, and scalable databases.

Entity Constructors and onTouch() Event

Define constructor logic and use the new onTouch() event for dataclass entities to react to attribute changes in memory. Centralize validation, initialize context-aware values, and bring lifecycle awareness directly into your data layer.

DYNAMIC FORMULAS FOR FORM OBJECTS

Bind form object values to live formulas using OBJECT SET DATA SOURCE FORMULA. Pair this with listbox constants like lk selected items expression for adaptive UIs that respond in real time—reducing code duplication and boosting clarity.

NEW UDP COMMANDS

Leverage 4D.UDPSocket for low-overhead, event-driven messaging. Listen with onData, track errors, and inspect events with 4D.UDPEvent.

TCP CONNECTION TIMEOUT CONTROL

Use the new .timeout property on TCPConnection to limit wait times and prevent frozen interfaces during slow or failed connections.

RECURSIVE DEPENDENCY RESOLUTION & MANAGEMENT

The Component Manager now handles recursive dependency loading, detects cyclic references, and ensures components initialize in the correct order—so your modular architecture stays clean and predictable.

Create, update, and delete events in Microsoft 365 and Google Calendars

Use cs.NetKit.Office365.calendar and cs.NetKit.Google.calendar to create, update, and delete events—complete with attendee lists, recurrence rules, meeting links, and notifications—all via secure OAuth2.

BuildApp License Automation

BuildApp now detects valid deployment licenses and embeds them automatically. Choose your mode (manual, auto, evaluation), track usage in logs, and get clear post-build reports in the UI.

Secure Paste for Formulas

Formulas pasted from external sources are now sanitized—only evaluated results are retained in multi-style fields and Write Pro areas, reducing the risk of unintentional logic injection.

MECAB REMOVAL

The MeCab library for Japanese segmentation has been removed. If needed, custom tokenization logic can be implemented using ORDA and component-based queries.
