In my case this release, and 1205/1206 make WiFi do not work at all. There are no visible option to even try to connect. ifconfig do not show any wireless device.

Have you tried #1207 (is that what you mean by "this release" - I don't like guessing).

If #1207 isn't working please post pastebin links to your dmesg from #1204 (which I assume is working) and also #1207.    

Well i wasn't sure if the problem started with #1204 because i was using ethernet cable, and was just checking 1205/1206/1207 if there is wireless signal (i read about some dependencies between wifi and BT when i was trying to find solution for my earlier problem).
So i checked few releases and there is no wifi card detected.
So i moved into the past... LibreELEC-Generic.x86_64-9.0-Milhouse-20170202210210-#0202-g8d14fdd - no wifi, and...
LibreELEC-Generic.x86_64-8.0-Milhouse-20161201042826-#1130-g0ad9cf6 also no wifi. I chkecked like 6 from many months and wifi wasn't working, so i think it is from the beginning.
BUT - in the stable release WiFi is working, and i can use it.
Here are logs between versions:
