Google just updated the Gmail iOS app with a number of new features. Perhaps the most notable is that Notification Center support provides users with banners, alerts, and lock screen notification options that are manageable from settings. Google also noted on the Official Gmail Blog that notifications in the updated app are “up to 5x faster than in the previous version.”

Another new feature is a “From:” option when composing a new message. It allows you to switch between sender addresses under Settings->Accounts->Send mail as from Gmail on the desktop. Finally, Google explained the improved “persistent logins” would allow you to stay logged in as long as you want:

“we’ve improved the login process to allow you to stay logged into the app for as long as you’d like. You can still choose to sign out of your account, but you won’t be automatically logged out after a certain period of time has elapsed.”
