Deprecated useAppcache Attribute in aura:application

Browser vendors have deprecated AppCache, so we followed their lead. Remove the useAppcache attribute in the <aura:application> tag of your standalone apps (.app resources) to avoid cross-browser support issues due to deprecation by browser vendors. If you don’t currently set useAppcache in an <aura:application> tag, you don’t have to do anything because the default value of useAppcache is false.

We included this information in a patch release for the Spring ’17 Release Notes. We’re repeating the deprecation notice in case you missed the patch update.
