 ## Unreleased
 
+### Bug Fixes
+
+- The command `operator-sdk olm-catalog gen-csv --csv-version=<version> --update-crds` would fail to copy over CRD manifests into `deploy/olm-catalog` for manifests whose name didn't end with a `_crd.yaml` suffix. This has been fixed so `gen-csv` now copies all CRD manifests specified by `deploy/olm-catalog/csv_config.yaml` by checking the type of the manifest rather than the filename suffix. ([#2015](https://github.com/operator-framework/operator-sdk/pull/2015))
