Managing Project Dependencies Has Never Been Easier
With the latest updates to the Project Dependency Manager in 4D 20 R8, your projects are always a step ahead. Dependencies are regularly checked for updates, giving you access to the latest versions and enabling you to make informed decisions about when and how to integrate changes.
Additionally, you’re in full control with the ability to edit dependency rules, providing unmatched flexibility. Adjust these rules—whether to opt for the latest version, up to the next major, or up to the next minor version—to ensure your project evolves on your terms, balancing innovation with stability.
Empower Your Development Process with your forms
During the development phase, early detection of syntax errors is important for producing quality code. Real-time code checking is a valuable aid to developers. Not only does it improve efficiency, it also enhances quality and boosts productivity. By correcting errors immediately, you can concentrate on the functional development of your application, rather than on annoying bugs that crop up during compilation.
With 4D 20 R8, we’re delighted to introduce two new features that will transform the way you work.
- The first is the ability to associate a class with a form, enabling syntax checking with expressions such as Form.myProperty.
- The second is a real-time check of expressions in the property list, with a description of the error or warning displayed.
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!
IMAP API: Retrieve Unread Email Counts for multiple mailboxes in One Call
Many of you rely on IMAP commands to display the number of unread emails in your app’s UI, helping users stay informed about new messages. With 4D 20 R7, we’ve enhanced the IMAPTransporter.getBoxList() function, enabling it to retrieve unread email counts and mailbox properties simultaneously, ensuring faster response times.
Enhancing Compilation with Direct Typing in 4D
With 4D 20 R7 you can say goodbye to “Compiler_” methods and embrace more freedom in how and where you declare your variables. Save time by staying focus on your development workflow and your coding process thanks to Direct Typing.
4D NetKit: Retrieve Unread Email Counts for multiple labels in One Call with Gmail API
A lot of you use Gmail commands to show the number of unread emails in your app’s UI to let users know about new messages. So, starting with 4D 20 R7, we’ve upgraded Google.mail.getLabelList() function so that it can get the number of unread emails along with label properties for Gmail all at once to ensure optimal response times.
4D Write Pro: Mastering Sections and Subsections with new functions!
Sections and subsections are the building blocks of any well-structured document. You’ve likely used them countless times, perhaps without even realizing it, as every document contains at least one section by default!
Whether you’re a seasoned pro or just starting out, this post will walk you through the basics of sections and subsections.
We’ll also explore the exciting new 4D Write Pro features in 4D 20 R7, which make managing these elements easier and more powerful than ever.
Listbox: “Blank if null” for TIME Columns and Footers!
For many versions, the “Blank if null” property has been available for “time” type zones, whether for input or display. However, it was not previously available for columns or footers of this type in listboxes. With 4D 20 R7, this limitation has been removed!
Access Qodly Studio for 4D directly from your 4D server to test and debug your code
Qodly Studio for 4D allows you to extend your 4D applications with web pages. Development is integrated into 4D Developer Edition.
During the development phase, there are often times when specific features or bugs can only be replicated on a server or in a production environment. This poses a challenge for developers, who require direct access to debugging tools to efficiently resolve issues.
With the latest release of 4D 20 R7, Qodly Studio for 4D is now accessible directly from your 4D server, you can debug and test your Qodly application like never before.
Here’s a quick guide on how to make the most of this new feature.
