What shipped,
in order.

Runtime, control plane, and dashboard changes from the open-source PandaStack project.

2026-05-31
v0.5.0

Org-ready agent runtime

  • WebSocket multiplexed exec: tagged command frames, cancel, keepalive pings, and ~5ms socket-reuse overhead.
  • Organizations, members, invites, role hierarchy, personal-org provisioning, and dashboard org switching.
  • Stripe metered billing with pending_meter_events and 60s idempotent Meter Events worker.
  • Dashboard /settings/team, /settings/billing, and /settings/orgs shipped with org-switcher dropdown.
  • TypeScript and Python SDKs now expose sandbox.fork(), sandbox.forkTree(count), and promote(...).
2026-05-25
v0.4.0

Snapshot restore at production concurrency

  • Every create restores from a baked per-template snapshot for sub-75ms starts across common stacks.
  • Concurrent restore paths tuned to avoid head-of-line blocking during agent bursts.
  • Scheduler health checks now drain cold hosts before user-visible boot latency regresses.
2026-05-20
v0.3.5

Preview links and cleanup safety

  • Preview URLs for sandbox ports with auth-aware sharing primitives.
  • Postgres zombie-sandbox sweeper to reconcile dead agents and stale rows.
  • Network namespace DNAT fix for restored sandboxes after host churn.
2026-05-12
v0.3.0

Hibernate, MCP, and time-travel restore

  • Idle sandboxes hibernate to disk with sub-second wake on next request.
  • MCP server exposes sandbox create, exec, upload, and preview primitives to Claude and Cursor.
  • Time-travel snapshot / restore foundation for branchable agent execution.
2026-05-01
v0.2.5

Identity-preserving migration

  • Cross-agent snapshot restore now carries baked NATID for stable external identity.
  • Preview URL ACLs added for interview prompts, demos, and scoped customer links.
  • Restore metadata normalized so sandboxes can move hosts without broken routing.
2026-04-20
v0.2.0

Fork API and hibernation events

  • First public fork API for snapshotting a running sandbox and restoring a sibling.
  • Warm-fork phase landed for lower-latency branch creation.
  • Lifecycle events added for hibernate, wake, fork, restore, and stop transitions.
2026-04-01
v0.1.0

Phase 3 microVM primitives

  • Fork, hibernate, and eventing primitives established as the Phase 3 runtime baseline.
  • Firecracker boot path stabilized around warm snapshots and XFS reflink rootfs copies.
  • Initial Apache-2.0 marketing site, docs index, templates, and pricing pages shipped.
