+
+Add a default catalog value for BitBucketDiscoveryProcessor. This allows to have a target like so: https://bitbucket.mycompany.com/projects/backstage/repos/service-*
+which will be expanded to https://bitbucket.mycompany.com/projects/backstage/repos/service-a/catalog-info.yaml given that repository 'service-a' exists.
+
+## Migration
+
+If you are using a custom [Bitbucket parser](https://backstage.io/docs/integrations/bitbucket/discovery#custom-repository-processing) and your `bitbucket-discovery` target (e.g. in your app-config.yaml) omits the catalog path in any of the following ways:
+
+- https://bitbucket.mycompany.com/projects/backstage/repos/service-*
+- https://bitbucket.mycompany.com/projects/backstage/repos/*
+- https://bitbucket.mycompany.com/projects/backstage/repos/*/
+
+then you will be affected by this change.
+The 'target' input to your parser before this commit would be '/', and after this commit it will be '/catalog-info.yaml', and as such needs to be handled to maintain the same functionality.
