Tailored Customization for Dates and Times

The manipulation of dates and times often requires specific formatting for various representations based on 4D’s internal resources or operating system settings.

While the default formats are usually all you need, there are scenarios in which custom formatting is essential, particularly for different geographical locations or unique requirements. In 4D v20 R4, significant advances have been made to meet this precise need

In the next phase with 4D v20 R4, we’re expanding this approach to intercept errors during expression execution.
Let’s delve into the details.

Auto-Generated SSL/TLS Certificates for Client-Server Communications

To simplify the security of client-server communications, from 4D v20 R4 onwards, 4D Server generates its own SSL/TLS certificates instead of relying on the default certificates provided by 4D.

This update brings a significant advantage for both testing and production environments. You’ll experience heightened security measures without the necessity of providing your own certificates. Let me explain to you what will change.

Structure Definition Export in HTML

Sharing structure definitions with colleagues, users, or customers is simplified through HTML formatting.

In 4D, structure definitions are presented in XML+XSL, which browsers render as HTML for easy human readability and computer-based content parsing.

However, recent browser restrictions prevent local files from using certain external resources unless sourced from the web. To overcome this issue, 4D has now re-factored this export in an HTML+CSS format, providing the option to export either XML as before or directly as HTML.
