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.
Note
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.
