If you go to the download page it funny enough first attempted to serve me the older and more reliable CLI program, supposedly tried and tested, and only at the second attempt offered the GUI program for download. I'ld have to check if this problem is also present in the CLI version (it wasn´t previously when used around three years ago as I ran frequent tests) but for now with the move to a more comfortable graphical interface I've only got the new app installed.
Most sites like whatismyip.com will tell you that everything is fine. It seems like they're only running one test. Also, when tested on AirVPN's ipleak.net everything appears fine at first glance. However, they're running more tests and eventually after around 20-30 seconds suddenly a second DNS is detected and pops up as visible in the screenshot below. This is the DNS of the ISP.
Here's an excerpt from the announcement.
"Well folks, in spite of the dire predictions of YouTube pundits, this morning the Slackhog emerged from its development den, did *not* see its shadow, and Slackware 15.0 has been officially released - another six weeks (or years) of the development treadmill averted. This has been an interesting development cycle (in the "may you live in interesting times" sense). Anyone who has followed Linux development over the years has seen the new technology and a slow but steady drift away from the more UNIX-like structure. The challenge this time around was to adopt as much of the good stuff out there as we could without changing the character of the operating system. Keep it familiar, but make it modern. And boy did we have our work cut out for us. We adopted PAM (finally) as projects we needed dropped support for pure shadow passwords. We switched from ConsoleKit2 to elogind, making it much easier to support software that targets that Other Init System and bringing us up-to-date with the XDG standards. We added support for PipeWire as an alternate to PulseAudio, and for Wayland sessions in addition to X11. Dropped Qt4 and moved entirely to Qt5. Brought in Rust and Python 3. Added many, many new libraries to the system to help support all the various additions. We've upgraded to two of the finest desktop environments available today: Xfce 4.16, a fast and lightweight but visually appealing and easy to use desktop environment, and the KDE Plasma 5 graphical workspaces environment, version 5.23.5 (the Plasma 25th Anniversary Edition). This also supports running under Wayland or X11."
Also, for the first time ever a "make_world.sh" script that allows automatically rebuilding the entire operating system from source is included. All the sources have been tested and confirmed to build properly.
