Both download links for stable LXQt and testers LXQt on /wiki/ISO#testers_LXQt link to Kicksecure-LXQt-18.1.4.2.Intel_AMD64.iso at the time of writing
https://www.kicksecure.com/download/iso/18.1.4.2/Kicksecure-LXQt-18.1.4.2.Intel_AMD64.iso
When I go to https://www.kicksecure.com/download/iso/ I see a newer release /18.1.6.4?
Is that the correct testers .iso?
