- A new open source program has been added to the Free Static Code Analyzers page. This one analyses C programs on Linux, macOS and Windows (via WSL).
- New article: How to Convert Your Website from XHTML 1.0 to HTML5 the Quick and Easy Way. This guide takes you through the process of converting a website from XHTML 1.0 to HTML5 using the Fiverizer software. (Fiverizer is a program that I wrote to convert my own websites, all of which were also in XHTML 1.0. It may be downloaded and used free of charge.)
- New software: Fiverizer: convert a website from XHTML 1.0 to HTML5. If you have one or more websites written in XHTML 1.0, this program (which may be downloaded and used free of charge) lets you convert them to HTML5 without having to muck around with rewriting HTML and adding CSS.
- The Feedback Form Wizard has been fixed so that it can now, once again, create the CAPTCHA versions (ReCAPTCHA and hCaptcha) of the script. Apparently, somewhere along the line, I seem to have broken it during one of my internal updates. I'm very sorry for the inconvenience. Note: you do not have to recreate your script if you successfully generated it before. (The problem was that under certain conditions, the wizard choked and died before it could generate a script. So if you actually received a script, you are fine.)
- Updated: The Free Mobile-Friendly Layout Wizard has been updated. It will now place the meta charset tag before the title in the head section (so that it will be in the first 1 KB of your page even if you have a long title). In addition, if you select HTML5 as the output type, the shorter meta charset tag will be used.
- Steam Audio has been added to the Free Audio Libraries and Source Code page. This is an open source, cross-platform C library with plugins for Unity, Unreal Engine and FMOD Studio.
- Added Intel's open source monospace font to the Free Programmers' Fonts page. This one is designed to reduce developers' eyestrain and fatigue, and was made with people with poor eyesight in mind as well.
- A cross-platform open source C++ GUI library has been added to the Free GUI Libraries and Source Code page. It lets you code applications that can be compiled on Windows, macOS, Android, etc.
- A new Python compiler has been added to the Free Python Compilers and Interpreters page. This one compiles your code to native machine code, without any runtime dependencies.
- The script generated by the Feedback Form Wizard has been updated to improve compatibility with PHP 8 (eg, 8.0, 8.1, etc). Note: if you have generated your form and script after 1 January 2023, you already have this version (ver 3.2.0).
- Another service has been added to the Free File Sharing and Storage page. This one lets you upload up to 2 GB and set an expiry date for your files.
- A cross compiler that generates code for AmigaOS, Atari TOS/MiNT/Jaguar, WarpOS and MorphOS has been added to the Free C/C++ Compilers and Interpreters page. (You can also find the usual compilers for Windows, macOS and Linux there.)
- Have you ever wanted to use a font for (say) designing a particular picture but not wanted to install it permanently into your system? The newest addition to the Free Font Managers page lets you do just that. It allows you to temporarily install a font that will be available to all programs running in the system, as long as the manager is active.
- A new free, open source photo editor for Windows has been added to the Free Drawing and Painting Software, Image and Photo Editors page. This one does not even need to be installed, and can be placed on a USB stick.
- A cross compiler for Z80, 8080, 8085 (etc) has been added to the Free C/C++ Compilers and Interpreters page. The development system itself runs on Windows and macOS. Note that if you simply want to write Windows or macOS programs, you can also get normal compilers for those tasks from that page.
- A new Windows resource editor has been added to the Free Resource Editors, Compilers and Icon Editors. For those unfamiliar with what this is, a resource editor (in this context) is a type of software that lets you create dialog boxes, icons, cursors and other "resources" needed in a Windows program. They are usually used by programmers when they create a program, but can also be used by (say) webmasters to create icons (sometimes known as favicons) for their website.
- A new Eiffel compiler has been added to the Free Compilers and Interpreters for Miscellaneous Programming Languages page.
- A new open source Amiga emulator has been added to the Free Amiga Emulators page. This one runs on ARM-based boards like the Raspberry Pi, but if you can also find emulators for Windows, macOS, and Linux on the page.
- New page: How to Set the Height of a DIV Relative to a Browser Window (CSS). This article answers a visitor's question on how to set the height of a DIV (or even other elements) so that it is a percentage of the browser window/viewport. And no, using the percent unit (ie, "%") won't work the way you think.
- A new open source script has been added to the Free Content Management Systems (CMS) PHP Scripts page. This is a CMS that does not depend on any database server but saves its data in a text file. Amazingly, the entire download is only 48 KB and has only 7 files.
- A new open source software has been added to the Free Password Managers and Password Savers page. This latest one is a Windows program, but there are other programs on the page for macOS and Linux if you use those systems.
- If you are thinking of starting your own social networking website, take a look at the Free Social Network / Media Software page, where a new open source program has been added. This one lets you create a microblogging platform (like Twitter) where your users can post text, pictures, videos, and audio.
- Another open source program for Windows and macOS has been added to the Free Video Converters or Transcoders. Such software lets you convert video or movies between different formats.
- A parser generator (used by programmers who want to create language compilers and interpreters) that generates C# and Java source files has been added to the Free Compiler Construction Tools: Lexer and Parser Generators page.
- 4 new open source XML parsing libraries have been added to the Free XML Parser/Generator Libraries page. These programming libraries make it easier for you to write computer programs that handle XML files (whether they are configuration or data files).
- A new web hosting control panel has been added to the Free Web Hosting Control Panel Software page. Note that such software are only useful if you are running your own web server and want something convenient to manage it. If you merely want to start a website, see How to Set Up a Website instead.
- Another open source BASIC interpreter for Windows, Linux and Unix-like systems has been added to the Free BASIC Compilers and Interpreters page.
- New page: How to Give Alternate Table Rows a Different Colour (HTML/CSS). Give alternate rows of your tables a different colour ("color") to make it easier for your readers to distinguish which row is which. This article shows one way of doing this using CSS.
- Two replacement distributions for CentOS (with ready-to-use downloads) have been added to the the Free Linux Distributions page. These, like the CentOS of old, let you install systems that are binary compatible with the commercial Red Hat Enterprise Linux, thus letting you run programs (etc) that were designed for that system.
- New page: Free EPUB Readers (Ebook Viewing Software). If you have obtained ebooks in the EPUB format, you are not restricted to reading it on your hardware ebook device or mobile phone. This page lists many free (and open source) EPUB viewers that you can install on your computer to read them.
- New page: How to Generate the Free Let's Encrypt SSL Certificate on Your Own (Windows) Computer. Find out how to generate an SSL certificate for a website on your own computer. (For those wondering, SSL certificates are needed so that your site can be accessed using HTTPS instead of HTTP.)
- A new program has been added to the Free Font Editors page. This software lets you create your own TrueType or SVG fonts, and it runs on Windows, macOS, Linux, OpenBSD and FreeBSD.

- New page: How to Play a Song (or Some Other Audio Clip) from a List on a Website. One of my visitors wanted his users to be able to choose a song from a list, and have it play in an audio player on his web page. This article provides the JavaScript and HTML code for the task.
- The formerly-commercial DarkBASIC Professional, now free and open source, has been added to the Free BASIC Compilers and Interpreters page. If you are interested in writing computer games in the BASIC programming language, or any other type of program for that matter, check it out.
- A portable, open source C library that provides utility functions dealing with data structures, thread management, character set conversion, internationalization, and lots more, has been added to the Free C/C++ Libraries page. The library comes from the GNOME project, but is written to be independent of GNOME, and can be used on Linux, macOS, Windows and Unix-like systems.
- Two new lexical analyzer generators for Java have been added to the Free Compiler Construction Tools: Lexer and Parser Generators page. For those wondering, these are tools that make it easy for you to write computer programs that have to parse text input.
