Stream Massive Update Round

GetStream has recently undergone a comprehensive upgrade, enhancing various aspects of its product, including new API endpoints, improved official clients, updated documentation, and a redesigned dashboard for better usability. The improvements include a new JavaScript client that can be used both client-side and server-side, and the documentation has been rewritten to provide examples ready for use in Ruby, Node, Python, and PHP. Notable new features include notification feeds that facilitate app integration with real-time updates and unique reference management through the foreign_id field, allowing for easier activity deletion and uniqueness control. Additionally, GetStream now supports schema-less custom fields, enhanced control over fan-outs with the "to" field, and batch activity insertion, which simplifies importing large amounts of data. These updates aim to streamline the development of scalable social applications, offering users greater flexibility and efficiency.
