Apr 1, 2025OpenSlides/openslides-meta (April 2025) delivered a data-entry simplification feature by introducing default values for critical metadata in models.yml (language, theme accents, primary colors, warning colors, and meeting language configurations). This reduces manual input and ensures consistency when creating new entries across deployments. A single commit (4616f0a9281198942cd2dcb9dc9ecffeb2454519) changed values from required to default to enable easier inserts (#247). The result is faster onboarding, fewer data-entry errors, and improved maintainability of metadata models.
