I have the standalone ver 6.0 with the latest available update. The de-haze slider is "missing." Any thoughts? When I open the effects panel, the vignette and grain sub-panels are there but not the de-haze slider.
De-haze is a new feature available only in LR CC 2015. It will most likely be available in LR 7.
As a workaround, try
Invoke the Dehaze effect in LR6
