- Two compilers have been added to the Free Modula-2 Compilers page. (For those wondering what the previous sentence means, Modula-2 is a programming language that you can use to write computer programs. And loosely speaking, compilers are the software that translate your programs, written in a particular language, into a form that can run on the computer.)
- Another service has been added to the Free File Sharing and Storage page. This site lets you share files of up to 2 GB, without the need to sign up for an account.
- A new emulator has been added to the Free Atari Emulators page.

- New page: Free Software to Create Bootable and Multi-Boot USB drives. If you have ever needed to boot from a rescue disk, or an operating system installation disk, only to find that they are distributed in the form of an ISO file or CD/DVD media, these utilities allow you to transfer them, in bootable form, onto a USB thumb/flash drive. In fact, some of them can even create bootable drives containing multiple ISOs, with a menu that appears on startup, letting you select which to boot from.

- Updated: The Feedback Form Wizard has been updated to include an additional CAPTCHA option. This one is not only free, it apparently even pays you when your visitors solve the CAPTCHA challenges. For those wondering, CAPTCHAs are those "I am not a robot" or "I am human" checkboxes on forms, used to make sure that a human is at the helm, and not some spam robot.
Updated: How to Add a CAPTCHA Test to Your Feedback Form Script: Reducing Spam in Your Contact Form. The article on how to add a CAPTCHA to your contact form has been updated to include information on how you can use the newest CAPTCHA option (the one that potentially pays you for using them) of the Feedback Form Wizard.
- A new program has been added to the Free Static Code Analyzers (Lint) page. Such tools scan the source code for your program, looking for potential bugs and vulnerabilities (even before you compile and test it). The latest addition can handle programs written in Java, JavaScript, C#, TypeScript, Kotlin, Ruby, Go, Scala, Flex, Python, PHP, HTML, CSS, XML and VB.NET. (If you use a different language, such as C, C++, Fortran, there are other tools listed on that page that can scan those too.)

- If you are frustrated with how clumsy it is to work with Windows Explorer, when you want to copy or move files between two folders, you may want to use one of these new additions to the Free File Managers and Graphical Shells page. One of them makes multi-panel (dual-panel or four-panel) Windows Explorer windows, and the other creates tabbed Explorer windows. And yes, you read that right. They actually reuse Windows Explorer for the actual windows.
- New page: How to Get the Hash (MD5, SHA1, SHA256, SHA512) of a File on Windows Without Installing Anything. Sometimes, when you download a file, the website you get it from also lists its MD5, SHA1, SHA256 and SHA512 hashes, so that you can verify that the file you obtained has not been tampered with or corrupted in transit. This article shows you how you can check those hashes using Windows' built-in programs.
- Another program has been added to the Free Video Editors page. If you are looking for software to process your video file, whether to do something simple like split it into smaller segments or extract a scene, or something more elaborate like add special effects, watermarks, image overlays, and so on, take a look at the many free programs available here.
- Another web conferencing computer program has been added to the Free Video Conferencing Software page. This one was originally designed by Microsoft for academic learning and collaboration, but has since been released as open source software.

- Two new sources of free certificates have been added to the Free SSL Certificates for Websites/Web Servers page. They may be useful if you are thinking of moving your website from HTTP to HTTPS.

- New page: Why Can't I Make Up Any Domain I Want? Is There a Way to Do Away with a Registrar Altogether? I was asked by a visitor why he couldn't dispense with a registrar and just make up any domain name he wanted. You may be surprised to hear that you can actually do that. But it won't do you any good.
- New page: How to Prevent Two or More Words from Being Split into Separate Lines (HTML/CSS). Sometimes you may want to keep a group of words on a web page together on a single line, rather than allowing the web browser to break them up and placed on separate lines if there's no space. This article shows you the HTML and CSS to accomplish this.
- Two more emulators have been added to the Free Amiga Emulators page. One of them runs in a modern web browser (which means it can work on Windows, macOS, Linux, etc), and the other works on the Playstation Portable (PSP). (For those wondering, Amiga emulators are software that allow you to run Amiga programs and games on your modern computers, by mimicking the original Amiga computers.)
