That link is about a windows release. There's no mention of linux at all.
I'm a recent adopter of maxthon across all my devices, windows, android, mac and linux.
This thread is the first I've heard of a risk of no linux commitment. I looked for such info when I first started with maxthon and found the version mis-match, but no explanation. It's not uncommon so I went with it.
I've invested many hours into making maxthon my alternative browser. Part of me thinks there should have been a warning on the download page, as this now feels like wasted time.
