+# v3 Migration Guide
+
+## Consumer Settings Changes
+
+The v3 consumer command uses a [different library](https://watchfiles.helpmanual.io/) to unify
+the watching for new files in the consume directory. For the user, this removes several configuration options related to delays and retries
+and replaces with a single unified setting. It also adjusts how the consumer ignore filtering happens, replaced `fnmatch` with `regex` and
+separating the directory ignore from the file ignore.
+
+### Summary
