4D v20 Beta Starts Today

We’re excited to announce that beta testing for 4D v20, one of our most anticipated LTS versions yet, is starting today!

With over +100 advances, including enhancements to existing products and highly requested features that have been voted for by our 4D developers, this release promises to be one of our most comprehensive and feature-rich releases yet.

Buckle up, and let’s discover some of what 4D v20 Beta has to offer:

 

  • Build real-time web applications that can handle large volumes of data and provide a seamless user experience with the new built-in WebSocket Server.
  • Work with complex data structures with object and collection literals that provide a more concise and readable way to initialize objects and collections in your code.
  • Quickly and efficiently search and replace code with the Find and Replace feature improvements.
  • Create a custom “Help” menu for your application by passing a collection describing the menu items.
  • Save time and quickly analyze and organize your data with 4D Write Pro’s tables, which automatically fill your data in tables with page breaks, headers, footers, and even break rows.
  • Take advantage of 4D Write Pro text boxes (floating containers) to print complex product flyers or brochures.
  • Evaluate the new feature, QUIC Network layer, a total rewrite of Client/Server communication. Built on UDP instead of TCP, it facilitates faster recovery in case of packet loss, congestion, and other issues that can cause delays and disruptions in network traffic.
  • Native support for Microsoft 365 using the Microsoft Graph API allows sending, receiving, organizing emails, and handling user authentication with Single Sign On (OAuth2)
  • Much more awaits you with this LTS (see below)

ORDA – From Beginner to Expert

ORDA, which stands for Object Relational Data Access, is a method of accessing data that combines the advantages of object-oriented programming with those of relational databases, allowing developers to focus on solving business problems rather than managing data access.

Whether you are new to ORDA or already familiar with it and want to expand your knowledge, consider this blog post a road map to guide you through the learning process.

Filter Access to your Data with a Complete System of Permissions

Filter access to data is a must-have feature to prevent malicious access to your application.

So far, you could expose or not expose as a REST resource a dataclass and some of its attributes. It was already a convenient means to restrict access to your data. Still, we’re thrilled to deliver in the v19R8 a powerful and fully customizable system to protect your data from unauthorized users. A system to protect your data depends on who is accessing it and which data is accessed.

Build your Compiled Structure or Component with Build4D

With the introduction of the project mode, it’s pretty easy to manipulate the components of your projects.

In the last few feature releases, we have added several functionalities that allow you to create your own build chain adapted to your team, your working methods, and your needs.

For example:

 

To help you create your own build chain or integrate 4D into a continuous integration tool, we have developed a component named Build4D, available on GitHub with the sources.

For this first step, Build4D allows you to create a compiled structure and a component. We will continue to enrich it to enable you to manage a single-user application, client application, or server application.

Latest Improvements of the HTTP Client

With 4D v19R6, we brought you a new way to perform HTTP requests: HTTP classes. At that time, some of the HTTP classes functionalities were not final, as we wanted to adapt them to the new syntax. It is now done! In v19R7, compressed responses, chunked responses, and redirections functionalities are now complete.

As a bonus, we also added a new way to log HTTP requests. And as it’s helpful to everyone, this new logging is available to the new HTTP classes as well as for the legacy syntax.
