Yahoo is now breathing new life into Yahoo Messenger with a set of new messaging apps.<br />The older web-based Yahoo Messenger will continue to be supported for the next couple months but will eventually be retired, the company says.<br />On the surface, the new Yahoo Messenger app is similar to WhatsApp, Facebook Messenger and other messaging apps: Log in with your phone number (or your Yahoo Mail account, if you have one) and the app scans your contacts for people you know who also use the app.<br />But the revamped Yahoo Messenger does have a few tricks of its own, including built-in GIF search (via Tumblr) and the ability to share large numbers of photos almost instantly, regardless of whether you're on Wi-Fi or a data connection (via Flickr.)<br />You can also like individual messages within a thread or unsend a message you've sent at any time.
