Channel Rewind and State Persistence

Ably introduces Channel Rewind, an optimization for its Pub/Sub Channels that simplifies the process of retrieving realtime messages sent over a channel prior to connection. With this feature, developers can now connect to a channel, instantly load the state, and subscribe to all future realtime updates with a single API interaction. Channel Rewind is useful in various scenarios such as location tracking, weather updates, chat applications, IoT devices, and more. It also works well with Message Delta Compression and State Persistence features offered by Ably.
