News Official release announcement for 4D 20 R9 highlighting new features in the latest version of the 4D development platform, set against a colorful gradient background

Introducing 4D 20 R9 – Available Now!

You don’t need more tools. You need sharper ones. The kind that remove friction you’ve quietly accepted. That reduce context switching. That stay out of your way, until the second you need them.

4D 20 R9 does exactly that—cleaner flow, smarter control, faster outcomes. It’s not louder. Just better.

  • Built-In 4D AI Kit Component: AI where it belongs—inside your 4D application logic. Call third-party AI APIs like OpenAI directly in 4D using the built-in AI Kit component. Generate text, tag content, analyze images, automate tasks. No wrappers. No bridge apps. Native, fast, under your control.
  • AI Writing Assistant in 4D Write Pro: Edits shouldn’t break your flow. Use WP SetAIKey to link OpenAI and unlock the assistant. Summarize, translate, rewrite—all in 4D Write Pro, without switching tools.
  • New TCPListener Class: Your 4D application doesn’t just send—it listens. With TCPListener, accept incoming TCP connections. Integrate with smart devices, hardware, or or local systems—all with real-time control.
  • Edit & Debug Components in Host Project: Fix fast, stay focused. Edit and debug component code directly in the host project—no switching, no reloads. Breakpoints work. Changes apply instantly. You stay in context, reduce friction, and save dev time where it matters most.
  • Follow 4D Version for Dependencies: Upgrades and downgrades, now frictionless. Dependencies stay in sync automatically with the new “Follow 4D version” rule. No manual version tracking.
  • OTP & Session Restore: Secure flows, uninterrupted. Use createOTP() and restore() to build safe, multi-step web interactions. You can hand off one-time passcodes across third-party flows—while keeping session state intact.
  • Label Wizard & Code Editor Enhancements: Catch issues before they cost you. Insert and validate formulas safely in the Label Wizard. Deprecated syntax like C_LONGINT($1) now triggers smart warnings in the code editor.
  • Smarter OAuth & Calendar Integration: OAuth setup, simplified. Use host-based redirects for OAuth 2.0. Access Google and Microsoft 365 calendars with calendar.getCalendars() and calendar.getEvents().
  • Improved Document Imports in 4D View Pro: No more race conditions. VP IMPORT DOCUMENT and VP FLUSH COMMAND now wait for custom functions to complete before callbacks fire.
  • macOS UUID & OEM License Auto-Refresh: Unique builds. Seamless licensing. 4D 20 R9 assigns a UUID to every macOS build. OEM licenses refresh automatically—no manual renewals, no downtime.

This is just a glimpse of what’s available in 4D 20 R9. Download 4D 20 R9 and discover how far you can go with this feature release.
