+- Weaver: bump version to 5.1.1
+
+  - See changes in the [Weaver changes 
+    file](https://github.com/crim-ca/weaver/blob/ec5f403958de21e1af27ff86da391d0d53ded5d9/CHANGES.rst?plain=1#L23-L249)
+
+- Weaver: WPS retry logic on post-compose step.
+  - Apply `--network birdhouse_default` to the Docker `curl` image to allow HTTP requests to properly resolve
+    against the running services (WPS bird providers, Weave and Magpie). In some cases, this network would not
+    be automatically resolved.
+  - Fix the index used during HTTP request retry to avoid going one step over the intended retry attempts.
