Google just released its biggest update ever to its popular Gmail service.

The new features improve productivity and security.

Confidential mode allows you to set an expiration date where the content of an email message disappears after a specified date.  It also disables forwarding, copying and printing.

The new Nudge feature, reminds you to respond to messages that you may have missed.

A new security feature, boldly warns you if a message received seems suspicious.  If you don’t recognize the sender you can immediately delete the message.

You can also keep notes and to-dos in the new task bar.  This keeps you action items all in one place.
