a downgrade instead of a upgrade to tampermonkey in terms of numbers
How so? 1.064 is very old and doesn't even work properly from now on since Twitch updated their design. And especially if you've the new Highwind player (though they seem to have disabled it for now, or i'm just not anymore in its beta atm), or if you're using the squad stream feature.
There's no additional check being made outside of the first one for the player type, and the main checks are still using getElementsByClassName, so clearly, there's no downgrade.
Please beware from Updates from now on.
I don't why but it's appears to be that 1.12 compare to 1.064 is a downgrade instead of a upgrade to tampermonkey in terms of numbers. So, my point is to never use the x.0xx again, because its read like a superior version that the normal enumerating.
