According to Lightroom Killer Tips (on 16 June), Adobe are releasing updates to Lightroom CC and Lightroom Mobile - but not (not) LR6.
The LR Mobile changes allow more editing; while the LR CC adds, amongst other things, a new feature called Dehaze (or add haze) Effect which, Killer Tips, describes as "pretty darn slick..... and for anyone who shoots u/w photography or at an aquarium". Apparently it cuts through haze and doesn't just add contrast.
The Mobile version has already appeared through the usual App Store updates. I've not yet received the CC update.
