Steam has begun rolling out its new text and voice features, as well as its updated friends list, to all users beginning today. The Valve-owned video game storefront is increasingly trying to compete with popular chat app Discord, and it finally embarked on a quest to implement some popular and much-needed Discord-like features into the Steam client back in June, when it launched a beta version of its more robust Steam Chat. Now, those features look to be live as Steam tries to win back some of the Discord crowd it’s lost since the latter company launched just three years ago.

The new updates are mainly around design and chat versatility. Now you can share GIFs and rich social and video links with friends in Steam Chat, sort friends by favorites, group your friends by game and by party, and maintain more fully featured group chats that are designed more like Discord servers. Steam Chat also now offers built-in voice chat with many of the same perks, like channels and link inviting, that you get with Discord.
