Google Chat

Google first announced their plan to begin retiring Google Hangouts in October 2019.[4] In October 2020, Google announced that it would open Google Chat up to consumers in 2021. Google also announced that Hangouts conversations, contacts, and history would be migrated over to Google Chat.[5]

Google Chat began to roll out to consumer accounts in "early access" in February 2021,[6][7] but at the time Google stated that Hangouts would remain a consumer-level product for people using standard Google accounts.[8][9][10] By April 2021, Google Chat became fully available for free as an "early access" service, for users who choose to use it instead of Hangouts.[11]

In August 2021, Google started automatically signing out Google Hangouts users on iOS and Android and notifying them to switch to Google Chat.[12]

Google plans to deprecate Google Hangouts and replace it with Google Chat in early 2022.[13] In February 2022, Google announced plans to begin the final migration of all Google Workspace customers from Google Hangouts to Google Chat, which is scheduled to be finalized in May 2022.[14] In September 2022, Google announced all Hangouts data will be deleted by January 1, 2023.[15]

Spaces, originally called Rooms, is a chat room feature built within Google Chat for topic-based collaboration, with shared files, tasks and conversations.[17][18] It functions alongside Google Chat and Google Meet to integrate group productivity features like message threading and real-time collaboration to organize topic-based conversations without exiting Gmail.[19] The feature revives the brand name previously used in an unrelated service of the same name from 2016 to 2017, with the rebranding occurring as part of the expansion of Google Workspace to all users in 2021.[20][21] Spaces are designed for collaboration on long-term projects. In contrast to spaces, group conversations only support chatting and do not have any task functionality or a separate files tab to view a list of shared files.[22] Spaces also allow users to change the name of the chat, which is not possible with group conversations, and they allow users to only be notified when they are mentioned.[23] Each space has three tabs, a chat tab for chatting, a files tab for sharing files, and a tasks tab for creating and assigning tasks.[23]

The service is accessible from within Gmail alongside Chat and Meet as part of the Google Workspace expansion to all Gmail users.[24] With the relaunch, Spaces allows up to 8,000 users to collaborate on projects and utilize other Workspace features such as creating Google Drive documents and Google Meet meetings from within a Space,[25][26] as well as integration with Task creation and Calendar availability.[27] By the end of 2022, the Spaces team size limit will increase to 25,000.[28] Spaces are discoverable across an organization[29] and a Space's creator is the default manager of the space with the ability to delegate manager status to another user.[30] The move from Rooms to Spaces also brought improvements in moderation and security features.[31][32] In February 2022, Google rolled out a new Gmail interface for Workspace that was designed to better integrate Spaces as well as Chat and Meet.[33][34] Spaces is expected to gain increased functionality when Google Currents is shut down sometime in 2023[35] and user content is moved to Spaces.[36]
