API Reference, Sandbox Metrics & Private Images

API Reference, Sandbox Metrics & Private Images API Reference, Sandbox Metrics & Private Images

This release improves the developer and agent experience by introducing comprehensive API documentation and enhanced sandbox visibility. A new API reference component and an expanded guide for Reinforcement Learning (RL) via TRL provide deeper integration paths for advanced AI workflows.

For infrastructure management, Daytona now tracks started sandbox metrics and exposes per-sandbox resource limits directly in the dashboard, ensuring better resource transparency and management.

Functional upgrades include support for private images in the declarative builder and several critical API stability fixes.

We have addressed issues regarding account linking eligibility, build information loading performance, and JSON body validation.

Additionally, this version ensures regulatory compliance by requiring user consent before setting cookies across the dashboard and documentation sites, while also bumping Astro for improved documentation infrastructure.
