Many workers are about to leave on holiday trips, and Google is more than willing to help them avoid the office with an updated Gmail app for Android. The new release includes a vacation responder that will let fellow employees know that you're off the clock. If you're running Android 4.4 KitKat, you can also print email to avoid checking your phone during family gatherings. And if you simply must deal with that company report right away, you'll be glad to know that Gmail now supports file attachments of all types. The new app is gradually rolling out as of this writing, so don't be disappointed if you have to wait a little while for an upgrade.
