If you go to Files at this product page you’ll notice two files. While I can delete the old file every time I upload a new version, I was wondering if it’s possible to select which one KDE will install from the Download New Widget menu.
normally both (or more) files are offered for download with description, so the user can pick which one to download.
Note that there was a bug that just got fixed and released in KDE Frameworks 24, so downloading from kde-look.org should work normally again sometime during this week (it is temporary in a “frozen mode” not updating to the latest products until the fix got in). This bug only affected Frameworks 23, so any version before and after should be fine.
