Google announced automatic message translation in Gmail and starting in the next few days, you will see an option to “Translate message” in the header at the top of every message that is written in a foreign language.
Also Gmail made a small title tweaks, they changed the text in the browser tab so that you can more easily see if you have new messages. The tab now reads "Inbox (20) - user@example.com - Gmail" instead of "Gmail - Inbox (20) - user@example.com.”
