Phone Calls Tab in Gmail

Gmail added a tab that lets you make calls. If you've switched to Hangouts in the desktop Gmail interface, you should see a new phone icon at the bottom of the window. It shows a list of contacts that have phone numbers and it lets you search for names or phone numbers. Click a phone number to open an audio-only Hangouts window and dial the phone number you selected.

You can click "make a call" or use the search button to see the list of contacts. Google also suggests to "try our mobile apps for Android and iOS".

"Almost all calls to the U.S. and Canada are free from all countries where Hangouts calling is available. For the rest of 2014, the first minute of most calls to 25 countries are free, and you'll be charged for each minute after," informs Google. The list includes: China, France, Germany, Brazil, Russia, South Korea, Japan, India, United Kingdom.

Updated YouTube App for Apple TV

YouTube's app for Apple TV has a completely new UI that's more in line with YouTube's desktop and mobile interfaces. The updated app also includes personalized recommendations, shows suggestions as you type and lets you watch all the YouTube videos, not just some of them.

If you use Apple's remote, it's pretty cumbersome to enter a query. The new app shows search suggestions as you type and also displays search results, so it's easier to find a video.

YouTube's app now plays related videos automatically. You can pause the video and pick a related video from the list or you can sit back and watch some relevant videos picked by YouTube.

"The most consequential change is that YouTube videos on Apple TV will run with ads. Which also means that all of the videos that run on YouTube (most notably music videos) will now run on YouTube's Apple TV app," reports Re/code.
