Assets/P4Connect/Editor/PackageIcons.cs(30,31): warning CS0618: UnityEditor.BuildPipeline.BuildAssetBundleExplicitAssetNames(UnityEngine.Object[], string[], string, UnityEditor.BuildAssetBundleOptions)' is obsolete:BuildAssetBundleExplicitAssetNames has been made obsolete. Please use the new AssetBundle build system introduced in 5.0 and check BuildAssetBundles documentation for details.'

This is on my todo list.... Eventually.

The PackageIcons script is only used to create an Icon package for distribution.
It only runs under Unity 4 and it gives this script warning in Unity 5, since I only run it under Unity 4
I haven't bothered to fix it yet.

I think I ran into this before while showing P4Connect in front of a bunch of digital artists. It was part of the reasons artists-in-training are not using Perforce even they knew that that's what they need to do when they get into the industry.

I believe that this is fixed in GA.7 by #ifdefing the code for 4.X only.

If you see it in a release later than GA.7 please let me know.
