Logins no longer automatically expire
Google has released an important update of its Gmail client for iOS. The main change is the addition of Notification Center support, which enables banners, alerts, and lockscreen pop-ups for messages. When composing email users now also have the option of picking a different "send as" address, so long as the address is already configured in Gmail.
The app has lastly gained persistent logins. Previously the app would automatically log people out of a Gmail account after a given time, forcing them to re-enter their passwords to get messages. Logins should now effectively be permanent, although users can still choose to sign out at will.
The app is a free download, and supports any device running iOS 4.0 or better.
