In @.github/workflows/generic-gateway-chart-cicd.yml:
- Around line 19-20: The workflow sets helm-version default to "4.2.0" (used by
azure/setup-helm@v5) which may be incompatible with existing Helm v3
expectations; change the default for helm-version in the
generic-gateway-chart-cicd workflow to the repo's agreed Helm 3 pin (e.g., match
'helm-version' used in sw-cicd.yml or README, such as '3.21.0' or '3.2.4'), or
remove the hard default and require callers to pass a version, and add a short
comment near the helm-version declaration describing the supported Helm major
version to prevent accidental upgrades; ensure azure/setup-helm@v5 usage stays
compatible with the chosen helm-version.

🌐 Web query:
Is Helm CLI version 4.2.0 officially released and what are the documented breaking changes vs Helm 3 that impact helm lint, helm template, or helm package?
💡 Result:
Yes, Helm CLI version 4.2.0 is officially released [1][2]. It was published on May 14, 2026 [1][3]. Helm 4 introduces several architectural and breaking changes compared to Helm 3. While many workflows remain compatible, specific changes impact how you use commands like helm lint, helm template, and helm package [4][5]. Key breaking changes and impacts include: 1. Linting (helm lint) - The lint package has been refactored [6]. Specifically, it was moved to be part of each chart version to improve validation, including enhanced support for CRD directories [6][7][8]. - The linting process now returns early if the templates/ directory does not exist [6]. - Legacy Helm v2 template lint rules have been removed [6]. 2. Templating (helm template) - Post-renderers, which are used during rendering, are now implemented as plugins [5][8]. Consequently, you can no longer pass an executable directly to the post-renderer flag; you must use a configured plugin name instead [5]. - Several flags (e.g., --hide-notes and --render-subchart-notes) are deprecated and have no effect, as template output no longer includes notes by default [5]. - New template functions such as mustToYaml and mustToJson have been added [6][7][9]. 3. Packaging (helm package) - The internal package structure has been moved to versioned packages (e.g., pkg/chart/v2) to support future chart API versions [5][7][8]. - Plugin packaging, signing, and verification processes were overhauled, including the removal of unnecessary file I/O operations [6][8]. General breaking changes also include: - Removal of the HELM_EXPERIMENTAL_OCI environment variable; OCI registry support is now enabled by default [10]. - Flag renaming for certain commands (e.g., --atomic changed to --rollback-on-failure and --force to --force-replace) [7]. - Plugin system overhaul based on WebAssembly (WASM), which may require existing plugins to be updated for compatibility [7][10]. - If you use Helm as a Go library, the module path has changed from helm.sh/helm/v3 to helm.sh/helm/v4 [10][8]. For detailed migration steps and a full list of changes, refer to the official Helm release notes and documentation [11][4][5].

Verify Helm 4.2.0 compatibility before defaulting helm-version in generic-gateway-chart-cicd
File: .github/workflows/generic-gateway-chart-cicd.yml (Lines 19-20, also 85-86)
default: "4.2.0"
type: stringThe workflow now defaults helm-version to 4.2.0 (for both workflow_call and workflow_dispatch), installs it via azure/setup-helm@v5, and uses it for helm lint, helm template, and helm package. The repo still documents/pins Helm 3 expectations (.github/workflows/sw-cicd.yml uses helm-version: '3.2.4', and README.md lists helm-version as v3.21.0), so Helm 4’s breaking behavioral changes could affect lint/template/package outputs across callers.
