For apps that are now Universal, you need to indicate under requirements that they are universal, because there are users that may want to run native-ARM apps, if available (and if you own an ARM mac, why wouldn't you want to run native apps if available?). This free application is developed for Mac OS X 10.5.0 or later. The program is included in Audio & Video Tools. Maybe that means separate MU pages for each platform in the case of VLC, or you need to host both versions and offer the user a choice which file when downloading. The VLC media player installer is commonly called vlc-2.1.0.dmg, vlc-2.1.2.dmg, vlc-2.1.3.dmg, vlc-2.1.4.dmg or vlc-2.1.5.dmg etc. So come up with a system to handle this new world we live in, every day that goes by it only will get more confusing. VLC is the first app I've seen that comes as separate installers, but logical to think more will come, for whatever reason a Universal app is not available (technical reasons, licensing, size of the executable, who knows). There a many Universal apps now, but if you look at the MAc Update page for them, there is no indication that they are Universal and requirements still say Intel-64. As I've been telling MU for several months you need to come up with a system/policy for how to document and catalog Universal and/or ARM only apps. The download you are hosting currently as of this date is the ARM version.
VLC is now available in separate Intel and ARM (Apple Silicon) versions, with DIFFERENT versioning schemes.
