+## [v0.13.0] - March 24, 2026
+### What's New
+#### SiftClient Export API
+The `sift_client` module now exposes a public export interface and wrapper, making it easier to integrate with downstream tools and workflows.
+
+#### Module Migration to `sift_client`
+The `grpc`, `rest`, and `time` modules have been migrated from `sift_py` to `sift_client`. All imports from `sift_py` for these modules have been removed. This continues the transition toward `sift_client` as the primary interface ahead of the `v1.0.0` release.
+
+#### Arbitrary File Attachment Uploads
+File attachment uploads now support arbitrary file types (e.g., Parquet, pcapng) by falling back to `application/octet-stream` for unknown MIME types.
+
+#### Improved SiftChannelConfig URL Handling
+`SiftChannelConfig` now handles URLs more robustly, fixing gRPC connection errors caused by missing URL schemes.
+
+#### Streaming Ingestion Performance
+The streaming ingestion module has been refactored to use `sift_stream_bindings` types for improved performance.
