At this time both Go 1.19 and 1.20 are supported. The version specified in the go.mod file is the minimum version we expect Helm to be compiled against. This is the oldest supported version to support environments where others compile Helm. The Helm project is using Go 1.20 to build Helm itself. Updating to Go 1.19 also includes dealing with io/ioutil deprecation and some additional linting issues around staticcheck. All the staticcheck issues were in test files so linting was skipped for those. Signed-off-by: Matt Farina <matt.farina@suse.com>
