+### Bug Fixes
+
+#### Race condition when creating ingestion configs (PR [#562](https://github.com/sift-stack/sift/pull/562))
+
+`SiftStream` now attempts to create the ingestion config first and treats an `AlreadyExists` response
+as a successful lookup rather than an error. Previously, the logic fetched first and created on
+`NotFound`, which left a window where two processes starting simultaneously could both receive
+`NotFound` and then have one fail with `AlreadyExists`. The new approach also adds concurrent
+flow creation so that new flows added to an existing ingestion config are created in parallel.
