In thread "Sencha Cmd 5.0.2 Beta is Now Available" it says to add these lines:


Code:



"js": [
        {
            "path": "${ext.dir}/build/ext-all-rtl-debug.js"  // new default for generated apps
        }

And the comment above the code is:

[...] as well as (optionally) add the following missing entry to the "js" array in your app.json file:

How can I determine if the line is required (I refer to the "optionally" part)?

When will that file be used? Both development and release?

Will it always use the "rtl" version?
