i read directional specular was deprecated, i am not sure if it was replaced by something else.
It seems in general the lighting menus have been changed a lot

i know it may take some time to update the videos, but could you summarize what has changed on 2017?
It seems they improved mixed lighting though the details escape me until i finish reading the manual
Yes they did change some of the lighting settings. I've been hesitant to update the content as the lighting tools Unity has implemented are still somewhat buggy, although they may have been fixed. I'll take a look at the lighting settings in the latest version of Unity to see how well they work now and if so I'll update them.
Two of the biggest areas for lighting is the progressive light mapper that allows you to see what the lighting will look like before you bake it. It's incredibly useful as it can be frustrating to bake lighting for so long only to realize you forgot to make an object static and/or something doesn't look right. Here is some documentation on it: https://docs.unity3d.com/Manual/ProgressiveLightmapper.html
The other is the light explorer window which allows you to select all the lights in your scene to adjust them separately without having to search for each of them in your scene. All the other settings are nice to have and adjustments to older lighting settings, but those two are the biggest changes. You can read more about the light explorer here: https://docs.unity3d.com/Manual/LightingExplorer.html
thank you for the prompt answer. Do you recommend going to a previous versions of unity to follow on the courses?
when i installed i just downloaded the latest but if the new stuff is not good and it complicates the ramp up i may just get another version.
