 # Changelog
 
+## 1.5.5
+
+**Release date:** 2026-05-20
+
+This patch release fixes several reliability issues. HTTP artifact fetches
+could block indefinitely and stall reconciliations, the Kubernetes client
+transport accumulated a new retry wrapper on every reconcile causing
+unbounded memory growth, non-CRD objects placed under a chart's `crds/`
+directory were force-applied, and the Helm test action failed to find
+releases with names longer than 53 characters. It also moves Helm back to
+upstream v4.2.0 (off the Flux fork) and updates Kubernetes and fluxcd/pkg
+dependencies.
+
+Fixes:
+- Add configurable HTTP timeout for artifact fetching
+  [#1497](https://github.com/fluxcd/helm-controller/pull/1497)

+- Use ShortenName for release name in Test action
+  [#1498](https://github.com/fluxcd/helm-controller/pull/1498)
