Version history and updates to the SeaLegs Developer API

API Versioning

The SeaLegs API uses versioning in the URL path (e.g., /v3/). We follow these principles:

  • Major versions (v3, v4) may include breaking changes
  • Minor updates within a version are backwards compatible
  • Deprecated features are announced at least 6 months before removal
