Just the industry config in the V2Routes/Regions/SouthernCA folder

I downloaded the #4 update. I have backed up ALL files in the Run8 directory. After I run the update, what specific files need to be recopied back to the active run8 folder(s)? I am anxious to install the new LA route, but I assume I need the #4 update loaded first. Any advise.

Run 8 has released Update #4 for V2 Today. Below are a list of changes
[list]
[*]Adjusted the threshold PSI/Second reduction-rate necessary to trigger the Emergency-Application Valve; this solves a minor issue reported about inconsistent emergency-application dump behaviour. (Since the customer who reported this is from Australia, I've added the extraneous “u” to the word “behaviour” in his honor)
[*]Corrected a crash-condition null reference that sometimes occurred during uncoupling
[*]Fixed two code mistakes with NORAC signals regarding non-dwarf MediumClear and LimitedClear aspects (for the Selkirk and Mohawk routes)
[*]Fixed a code mistake regarding the rear trucks of the SD40 Tunnel Motors
[*]Fixed another possible cause of the random loss of Simulation Settings when the program exits
[*]Fixed issue with humped-cars slamming too hard into bowl-tracks that are close

An update was also released for the Selkirk/Mohawk Region which addresses track, signal, and scenery issues.
