UPGRADE TO 4D 21
IMMEDIATE BUSINESS VALUE.
LONG TERM CONFIDENCE.
4D 21 LTS is built for applications that are designed to last. It brings together years of evolution into a release focused on one outcome: delivering more value without increasing risk, cost, or operational complexity.
This upgrade is a rational business decision. You keep the same team, the same architecture, and the same delivery model, while expanding what your applications can do and how confidently you can position them with clients.
With 4D 21, intelligence becomes native, the web becomes an extension instead of a rewrite, documents become dependable business assets, and identity and communication move back under your control. At the same time, the language continues to mature in ways that protect delivery speed, code stability, and long term maintainability.
The result is a Long Term Support release that strengthens what you already sell and gives you room to grow.
4D 21: Your AI Engine
DELIVER MORE VALUE FROM THE DATA YOU ALREADY OWNIn 4D 21, AI is not an external layer you have to justify or maintain. It lives inside the platform, where your application already thinks. This lets you introduce intelligent behavior that increases perceived value without increasing architectural or operational cost.
Search and data access move from rigid queries to intent based understanding. Users reach the right information faster, training effort goes down, and large datasets remain usable as language and usage evolve. The same data now supports more users with less friction
Because meaning is part of the system, existing content gains value. Notes, descriptions, messages, and logs become reusable signals instead of passive text. You extract more value from what you already store, without redesigning models or collecting more data.
AI capabilities extend naturally into workflows. Summarization, translation, analysis, and generation enhance existing logic instead of creating parallel systems. Features are easier to justify, easier to price, and safer to support over time.
What makes this sustainable is control. Structured outputs and tool calling keep AI behavior predictable and explainable, which is essential for long lived business applications.
With AI embedded in the platform, you deliver smarter features, reduce integration risk, and confidently sell intelligence as part of your core offering.

4D Qodly Pro
EXTEND YOUR APPLICATION TO THE WEB WITHOUT SPLITTING YOUR ARCHITECTURE4D Qodly Pro turns the web into a controlled extension of your application, not a separate project. You expand reach and modernize interfaces without rewriting logic, duplicating teams, or committing to long term frontend maintenance.
Qodly pages sit directly on your existing ORDA model and server classes. Data, rules, and behavior stay centralized. What already works continues to work, now available through the browser.
Interfaces are assembled visually, using reusable components bound directly to your data. Delivery cycles shorten, changes are easier to absorb, and interface evolution stays predictable instead of fragile.
Desktop forms and Qodly pages coexist within the same application. Sessions, privileges, and licenses are shared. Users stay in context. Deployment stays simple.
Because 4D Qodly Pro follows the same Long Term Support philosophy as the rest of 4D, browser evolution is handled by the platform, not pushed onto your roadmap or your client’s.
With 4D Qodly Pro, the web becomes a growth lever, not a cost center. You expand scope while keeping architecture stable and maintenance under control.

4D Write Pro
DELIVER DOCUMENTS THAT SCALE WITH YOUR BUSINESSWith 4D Write Pro, document generation stops being a technical task and becomes a reliable business capability. Documents are no longer just outputs. They are controlled assets that reflect your data, your rules, and your professionalism.
Templates stay tightly connected to your application logic, allowing contracts, invoices, quotes, reports, and operational documents to be generated directly from live data. This reduces manual handling, keeps information consistent, and ensures every document reflects the current state of the business.
As data grows, documents remain stable. Layout, tables, and structured content adapt predictably without breaking downstream processes. Non technical users can generate documents with confidence, while you retain full control over structure, rules, and automation.
Exports remain consistent across formats. What you design is what gets delivered, whether as PDF, Word, or embedded content. This reliability supports professional delivery, long term archiving, and regulated workflows without post processing or rework.
Because templates stay readable and maintainable over time, document driven workflows evolve safely instead of becoming liabilities. Maintenance cost stays under control, even years after delivery.
With 4D Write Pro, documents scale with your data, support real business operations, and continue to earn their place in your application.

4D NetKit & Emailing
CONTROL IDENTITY AND COMMUNICATION AS PART OF YOUR APPLICATIONAs applications grow, identity and communication often fragment across external services. 4D NetKit brings them back under a single, coherent model that stays aligned with your application logic.
Authentication feels native while supporting enterprise identity providers. Authorization remains consistent across environments. Security improves without slowing delivery or complicating onboarding.
Email and calendar scheduling become part of your application’s behavior, not side channels users have to manage separately. Messages, labels, events, and meetings reflect workflow state instead of clutter. Communication becomes something your application understands, coordinates, and acts on.
With one model for identity, email, and calendar interactions, integrations are simpler, maintenance is lower, and the story you sell to clients is clearer and more credible. Trust becomes built in, not managed around.

The 4D Language
BUILD, CHANGE, AND SHIP WITH CONFIDENCEIn real business applications, the true cost is not writing code. It is changing it safely over time. With 4D 21, the language evolves to reduce delivery risk, protect existing systems, and keep long-term maintenance predictable as scope grows.
- Code reads closer to intent. Structure and shared behavior are easier to express and understand, which shortens onboarding, speeds up reviews, and reduces dependency on tribal knowledge.
- Mistakes surface earlier. Issues are caught closer to where they are written, keeping production incidents rare and releases calmer.
- Changes stay localized. Updates affect the parts you touch, not unrelated areas, making refactoring safer and easier to justify.
- Shared logic stays under control. Application-wide and per-user behavior lives in clear, intentional places, reducing duplication and accidental coupling.
- Error handling becomes deliberate. Failures follow controlled paths instead of surprising side effects, making behavior easier to explain and support.
- Data movement stays efficient. Synchronization focuses on what actually changed, keeping large datasets responsive without full reloads or workarounds.
- Concurrency becomes predictable. Shared state is easier to reason about, reducing race conditions and defensive locking patterns.
- Debugging takes less effort. What runs, for whom, and why is easier to inspect, shortening investigation time when something goes wrong.
- Maintenance noise fades over time. Codebases stay readable, legacy patterns shrink naturally, and long-term support becomes a strength instead of a burden.
With the 4D language in 4D 21, you build systems that absorb change, support long term commitments, and remain reliable long after their first release.

4D 21 is much more than this
Beyond what’s highlighted here, 4D 21 strengthens the parts of your application that decide long-term value.- More reliable client connections with QUIC keep users productive even on unstable networks, reducing interruptions, support overhead, and friction in mobile or remote environments.
- Stronger data consistency at scale protects long-running operations and automated workflows from silent errors, lowering risk as datasets and usage grow.
- Cleaner web and API foundations make integrations easier to deliver without compromising security, session control, or license usage.
- Faster, more dependable spreadsheets with 4D View Pro ensure large reports load quickly, calculate predictably, and remain usable as business data expands.
These improvements don’t add complexity.
They reduce risk, protect performance, and extend the lifetime value of the applications you deliver.
