Fortifying Security: 4D Embraces OpenSSL 3.1
In an era where data security is paramount, updating security libraries is crucial.
4D v20 has taken a significant step forward by upgrading its OpenSSL library from version 1.1 to 3.1.
This advancement brings forth a multitude of advantages and improvements for 4D developers, enabling them to build applications that are not only highly secure but also exceptionally efficient.
Now, let’s explore these benefits in detail.
Websocket Client
In today’s interconnected world, the need for real-time updates is paramount for websites and IoT applications.
A way to deliver information instantly to your sites or applications is to use the Websocket protocol which provides a full-duplex communication channel between a server and a client. From 4D V20, you can create a websocket server with the 4D.WebSocketServer class. We continue in v20 R2 with the 4D.WebSocket class that allows you to create a websocket client to connect to any websocket servers.
Create a standalone application with the Build4D component
A new build4D component has been available on GitHub for a few months. It empowers you to effortlessly create a compiled project or a component. Things are getting even better; this new component version will enable you to generate a single-user application, expanding the possibilities for your development workflow.
So with tool4D available since v20, integrating the application generation process into your CI (Continuous Integration) tools has become remarkably convenient.
Let’s delve into the details!
4D for Mobile Goes Open Source: A Big Step for the Community!
Declaring Class Properties
The 4D language is constantly improving. For v20, we bring you a new feature that will ease the use of your classes: declared class properties. Declaring your class properties will significantly improve autocomplete and give you meaningful errors when compiling. Do you want to know more about it? Let me show you how it works!
Logging ORDA Calls on the Server
Since its release, ORDA has grown in popularity and is now widely used on your production servers.
With 4D v20, we provide two improvements on how ORDA requests are logged server-side:
- The first is an improvement of the request log that will now give more information about ORDA calls.
- The second is the addition of a server-side ORDA log similar to the client-side ORDA log. Let me introduce you to these new features.
Build an Application with 4D Commands
Since several versions of 4D, different features have been added to create your own build chain. For example,
- the creation of a “.zip” folder,
- the addition of information such as the copyright on an executable or a “dll”,
- the creation of an “info.plist” file,
- and the new build4D component.
With 4D v20, two new features allow finalizing the creation of a standalone or client/server application in 4D code:
- the addition of an icon to an executable
- the generation of the deployment license file for a server (OEM license only) or a standalone application.
Data Explorer Embedded in 4D
Data Explorer allows you to view the data in your database. You can choose which fields to display, organize, filter, and sort the data.
With 4D v20, the Data Explorer can be opened in 4D instead of an external browser. Users can access the Data Explorer directly from the toolbar with just one click, saving time and improving productivity.
4D Write Pro & Text Boxes: docx Import/Export Options
Introduced with 4D v19 R8, text boxes allow you to insert text, tables, images, formulas, and other elements anywhere into your applications. This feature has been improved in v20 to include the ability to export and import these elements from and to docx documents.
In addition, a new export option has been added that is also valid for other document types!
IMAP: Mailbox Id and mail keywords
4D v20 brings two very useful features to IMAP Transporters!
Interacting with some IMAP mail servers and clients requires to manage custom keywords in mails, and benefit from some of their specific features.
We also added the mailbox ID support in our IMAP Transporter so that you can identify a given mailbox even after it is renamed.
