+
+### DEPRECATION NOTICE
+
+The `sift_py` module is deprecated as of **v0.10.0** and will be removed in **v1.0.0**. 
+Please use `sift_client` for all new development. Several minor releases will follow 
+before the major release to add features and give users time to migrate.

+### What's New
+
+- Stabilizes the [sift_client](https://sift-stack.github.io/sift/python/latest/#sift-client-api-new) module.
+- [Add FileAttachmentsMixin to TestStep](https://github.com/sift-stack/sift/pull/466)
+- [Add support for live rule field in sift-client](https://github.com/sift-stack/sift/pull/463)
+- [Adds batch rule update/create support to sift_client](https://github.com/sift-stack/sift/pull/456)
