CHANGELOG: CSV versioning
From
### Added
- New flags for [`operator-sdk new --type=helm`](https://github.com/operator-framework/operator-sdk/blob/master/doc/sdk-cli-reference.md#new), which can be used to populate the project with an existing chart. ([#949](https://github.com/operator-framework/operator-sdk/pull/949))
+- Command [`operator-sdk olm-catalog`](https://github.com/operator-framework/operator-sdk/blob/master/doc/sdk-cli-reference.md#olm-catalog) flag `--update-crds` optionally copies CRD's from `deploy/crds` when creating a new CSV or updating an existing CSV, and `--from-version` uses another versioned CSV manifest as a base for a new CSV version. ([#1016](https://github.com/operator-framework/operator-sdk/pull/1016))
### Changed
- Changed the Go, Helm, and Scorecard base images to `registry.access.redhat.com/ubi7/ubi-minimal:7.6` ([#1139](https://github.com/operator-framework/operator-sdk/pull/1139))
+- CSV manifest are now versioned according to the `operator-registry` [manifest format](https://github.com/operator-framework/operator-registry#manifest-format). See issue [#900](https://github.com/operator-framework/operator-sdk/issues/900) for more details. ([#1016](https://github.com/operator-framework/operator-sdk/pull/1016))
### Deprecated
