+## [v0.7.0-rc.5] - November 24, 2025
+### What's New
+#### SiftStream FlowDescriptors and FlowBuilders
+The `FlowDescriptor` and `FlowBuilder` structs have been added as a new way to send data with `SiftStream`.
+The `FlowDescriptor` while similar to the `FlowConfig`, represents the minimum required information to
+create the protobuf object required by the ingestion APIs in Sift. It allows flexibility in how "channels"
+can be uniquely identified within that flow, with the most performant option to utilize the channel's index
+to directly set the value, bypassing potential bottlenecks such as string allocations or hash operations.
+
+#### SiftStream Flow-Config Cache Updates
+When initializing `SiftStream`, if no initial flow configs are provided, `SiftStream` will populate it's cache
+with all known flows configs from Sift. This can help improve workflows that require restarting `SiftStream`, such
+as when deploying new containers or processes.
