The version was changed from v3.0.1 to v3, which appears to be a downgrade. Version v3 is a major version tag that may point to the latest v3.x release, but it's more common practice to use a specific patch version or minor version for stability. Consider using a specific version tag like v3.0.1 or the latest available v3.x version to ensure reproducible builds.
