Feb 1, 2026February 2026 (2026-02) overview for Daytona: Delivered significant platform improvements across volume management, sandbox resizing, observability, recovery, and API reliability. Implemented Volume Management Enhancements including a dry-run preview for cleanup, volume mountpath labels, safeguards against deleting volumes in use, and an exclusion period to protect new volumes, reducing risk of accidental data loss. Extended Sandbox Resizing to Go and Ruby SDKs to support CPU, memory, and disk resource adjustments, with cleanup of outdated resizing examples. Launched Grafana Cloud monitoring for Daytona Sandbox usage and provided OpenTelemetry integration guidance to improve observability and incident response. Introduced Sandbox Recovery Admin Controls with an admin endpoint and enhanced recovery logic for null snapshots and pruned image tags. Strengthened API Reliability with separated public/internal health checks, flexible sandbox ID handling, and user-facing messaging around API key invalidation when removing members. This work, along with CI/CD workflow improvements and dependency updates, improved stability, scalability, and operator visibility across the Daytona platform.

Dec 1, 2025December 2025: Delivered core reliability and developer-experience improvements across rate limiting, sandbox recovery, and webhook payload handling for Daytona. Highlights include preserving headers and status on rate-limit errors, standardizing trackers and introducing failed-auth rate limiting, fixing anonymous rate limits for system-role users, enabling sandbox recovery with a recoverable flag and endpoints plus documentation/examples, and aligning webhook payloads with docs by introducing DTOs and updating handlers for clarity. These changes improve security against abuse, reduce unintended access restrictions, enhance storage-error resilience, and improve API clarity for consumers and internal teams.
