Commands Renaming and Deprecations

As developers, we all appreciate efficiency and simplicity in our coding routines. The fewer keystrokes we need to remember, the better!

With this in mind, we’re revisiting and refining command names while deprecating outdated ones in 4D 20 R7 to make them shorter, more consistent, and aligned with modern development standards.

Energize your Web applications with the OutgoingMessage Class

In today’s digital world, a smooth and intuitive user experience is key to any web application’s success. A critical part of this experience is providing users with easy access to various resources—whether documents, images, or other data types. To make this possible, your server must manage and deliver different content formats efficiently.

With 4D’s 20 R7 new REST server feature, managing diverse content delivery is now easier than ever. Previously, the REST server could only return scalar, entity, or entity selection data. Now, it can deliver full web content directly—content ready for a browser to handle.

Downloading files or receiving binary data from the REST server is now straightforward, thanks to the new OutgoingMessage class. With it, you can easily customize responses to suit your needs.

Read on to explore how the OutgoingMessage class can enhance your application!

Encryption. Authentication. & Certificate Authority Validation

In recent releases, 4D’s security capabilities have been significantly expanded, particularly in the area of certificates. This includes auto-generated certificates for client-server communication, support for ECDSA certificates, and, with 4D 20 R7, the validation of certificate authority for client-server communication of engined applications. Some customers require the highest level of security, highlighting the importance of these features.

However, security can be complex, and there have been requests for an explanation of how a TLS/SSL connection works and the role of certificates. Therefore, before delving into the new features, it’s helpful to first break down the basic security concepts and their interactions.

Introducing Session Singletons

Singletons have been one of the standout features of 4D 20 R5. Previously, developers could leverage two types of singletons:

  • the process singleton, which is unique to each process but different across processes,
  • and the shared singleton, which is unique across the whole application.

With 4D 20 R7, we are releasing a new type of singleton: the session singleton!
