GitHub has introduced Organizations to streamline the management of group-owned repositories, enhancing workflow for businesses and large open-source projects by centralizing code and billing under a single account. Organizations offer advanced permissions control through teams, allowing for easy management of access levels, including a new read-only option. Each organization has its own dashboard context for focused work environments, and the feature is free for open-source projects. Organizations can be created by converting existing user accounts, and GitHub has updated its pricing plans to accommodate the new feature, offering tiered plans based on the number of private repositories while keeping public repositories free.
