 ## [Unreleased]
 
+### Added
+
+- Added two new crate features: `crds` and `kube-ws` ([#1162]).
+
+### Fixed
+
+- BREAKING: Fix compilation failures when not enabling default features ([#1162]).
+  This is achieved by removing the `clap`, `telemetry` and `versioned` features, which were previously enabled by default.
+  They have been removed as the stackable-operator code actually always requires them.
