+* `version` is a Pear version object holding incoming version information
 * `app` indicates whether the update represents an application (`true`) or platform (`false`) update
-* `filename` is supplied if the `perFile` option is `true` and is the path of the file from application root
-* `reloads` is supplied if the `liveReload` option is `true` and is an array of objects containing the original, previous and next module/component instances that can be passed on to a hot-reloader. Objects take the form `{ original <Module>, previous <Module>, next <Module> }`

-For launched applications, use the default behavior (`perFile: false`) to respond to platform and application updates in production.
-
-For developed applications, the `liveReload`, `perFile` and `paths` options in combination with `pear.config.watch` and `pear.config.dev` are useful for setting up project devex hot-reload functionality. In development mode `version` and `current` will always be `null`.

-**Options**
-* `liveReload <Boolean>` Default: `false` - auto-reload JS libraries and supply to `reloads` array to `listener` 
-* `perFile <Boolean>` Default: `liveReload` - rather than per incoming version, updates are per file
-* `paths <Array>` - array of paths to watch for updates on. Only applies is `perFile` is `true`
+* `diff` is an array of file paths from the application root (drive keys) that were updated
