The newest Dota 2 introduced a new feature called Anonymous Mode, which will be in handy for those who want to limit their interaction with other players as well as for streamers and content creators.
The mode hides avatars, nicknames and in-game chat messages from people that are not on your friends list. Besides that, the feature allows you to not see guild information from guilds you are not part of. The option is available in the Social tab in settings.
In addition to it, the update allows players to track their guild challenges progress during the game. The update also includes changes that were specified in patch notes for 7.27 but not added to the game at the time, including adjustments to Satanic, Solar Crest, Phoenix Fire Spirits, Nature’s Prophet talents, Dark Seer talents.
