• @lumo-framework/core - Core framework and types
• @lumo-framework/adapter-aws - AWS Lambda runtime adapter
• @lumo-framework/adapter-cloudflare - Cloudflare Workers runtime adapter
• @lumo-framework/utils - Shared utilities

Version Format

• MAJOR: Breaking changes that require code modifications
• MINOR: New features that are backward compatible
• PATCH: Bug fixes and minor improvements
• PRERELEASE: Alpha/beta releases (e.g., -next.3, -alpha.1)

Release Channels
