Ever have trouble sending large files as email attachments? There's now a new tool in the Gmail Compose window allowing you to attach Google Drive files to your email message. You can now insert files up to 10GB into your email message. Since the recipient will access these files from the cloud, they'll have access to the most current version as well.
Gmail's new compose experience, so you'll need to opt-in if you haven't already done so.
