Welcome to this morning's edition of "First To Know," a series in which we keep you in the know on what's happening in the digital world.
Today, we're looking at three stories from the tech world you may have missed. Twitter updated its mobile apps on iOS and Android with photo galleries and improved login verifications. The cross-platform mobile messaging app WhatsApp is adding voice features to its service. Millions of smartphone owners use the app -- particularly outside of the United States. And Facebook has tweaked its news feed to ensure you see content you may have missed. The feed is live on the web but has not rolled out to mobile devices yet.
Check out the video above for more details on these stories.
