## Key points

- Range: 4.0.6 -> 4.0.8
- Version move: 4.0.6 -> 4.0.8
- Scope from baseline: 9 files changed, 116 insertions, 23 deletions

## Release Summary

This release finalizes the next patch step after 4.0.6 by aligning project version defaults to 4.0.8 and keeping maintenance-mode behavior and endpoint messaging consistent for production users.

- Project version defaults now target 4.0.8 in runtime and SDK package metadata.
- Landing and availability defaults are set for normal operation while preserving fallback endpoint guidance.
- Release messaging keeps the same operational safety model introduced in 4.0.6.

## Maintenance and Availability Hardening

The maintenance gate introduced in 4.0.6 remains the foundation for traffic control and endpoint safety when the primary service is limited.

- 503 responses now consistently include alternative endpoint details for API consumers.
- Limited-mode web access continues to preserve tutorial/blog routes and blog assets.
- The root landing page still acts as the canonical status and fallback handoff surface.

## SDK Track Updates

The official Python SDK remains the primary documented path, and this release now explicitly points TypeScript users to a maintained alternative package.

- Python SDK remains available through OpenMLBB with endpoint coverage aligned to API routers.
- TypeScript users now have a documented alternative: npm install mlbb-sdk.
- SDK onboarding text in docs and web UI now clarifies Python-first plus TypeScript-alternative usage.

## Configuration and Donation Defaults

Configuration defaults were refreshed to match current operational expectations and support messaging.

- Availability defaults target active service mode for regular traffic conditions.
- Support message baseline now reflects donation minimum guidance from $5.
- Date/version metadata in config has been moved forward for the 4.0.8 release line.

## Upgrade Guidance

No major API route break is introduced in this patch. Existing clients can upgrade with minimal friction.

- If you use OpenMLBB, update to the 4.0.8 package version and re-validate your environment defaults.
- If your project uses TypeScript, evaluate mlbb-sdk as an alternative client integration path.
- Keep fallback endpoint handling in your client for limited-mode or high-traffic windows.
