Lightning App can't read x-zip-compressed Static Resource

I'm working on the Lightning Developer Trailhead and the Lightning Component Developer Guide Quickstart, and in both cases, I've uploaded a static resource (as instructed) to be used by the applications in question.  However, the SLDS zip file doesn't appear to be working.  I have an older version of the SLDS in my org (v090) that is is file format application/zip, and that one works fine.  But the newest few SLDS downloads are in file format application/x-zip-compressed and none of these zip files in that format are working.  What am I missing here?

Nevermind, I figured it out:
The first line of the app in both examples use the following:
    <ltng:require styles="{!$Resource.SLDSv2+'/assets/styles/salesforce-lightning-design-system-ltng.css'}"/>

However, the newest LDS zip-files have the asset file named without the final 'ltng' so by changing the ltng:require tag to 
    <ltng:require styles="{!$Resource.SLDSv2+'/assets/styles/salesforce-lightning-design-system.css'}"/>
everything now works.
