What's New

Adds interactive processes, multi-cluster fleet planner, and SDK parity improvements.

Breaking Changes

  • Sandbox CRD now rejects names longer than 63 characters when `spec.service` is true.
  • `proxy.Lookup` interface changes to use `Resolve` instead of `Get`/`GetByName`.

New Features

  • Interactive processes with full PTY support via `commands.start()`.
  • Multi-cluster warm-pool fleet planner for capacity-aware replica placement.
  • Go and Python SDK parity with injected `ApiClient` and health/metadata APIs.
  • New Docker sandboxes example for KVM-enabled nodes.
  • Configurable warm-candidate grace period for slow IPAM/CNI environments.

Improvements

  • Enhanced Go and Python SDK parity with timeouts and tunnel support.
  • Configurable warm-candidate grace period for slow IPAM/CNI environments.
  • New `examples/docker-sbx` example.

Bug Fixes

  • Fixed warm-pool status updates under API throttling.
  • Fixed dropped PTY output in `sandboxd`.
  • Fixed stale evictions in router cache.

Upgrade Notes

Ensure Sandbox names are 63 characters or fewer if `spec.service` is enabled, or disable the service. Update `proxy.Lookup` implementations to use `Resolve` instead of `Get`/`GetByName`.
