# Changelog (/changelog)



This log covers the public API surfaces, the console, and platform behavior. It is intentionally high-level; per-endpoint detail lives in the [API reference](/api-reference/introduction).

<Update label="2026-06-12" description="Login plane and billing controls">
  ## Console accounts and billing [#console-accounts-and-billing]

  * Real login plane: email and password (Argon2id), plus Google and GitHub sign-in. Sessions are httpOnly cookies; password reset revokes all other sessions.
  * Email verification gates API-key creation. An unverified account can sign in but cannot mint keys.
  * Stripe-backed billing: the $5/month base plan, prepaid pay-as-you-go [credits](/pricing/credits-and-budgets), and the Stripe customer portal.
  * Budget controls: hard monthly caps, 50/80/100% alert thresholds, [per-key budgets](/authentication), and explicit overage opt-in recorded in the audit log.
</Update>

<Update label="2026-06-09" description="BYOK, governance, and data rights">
  ## Bring your own keys and enterprise governance [#bring-your-own-keys-and-enterprise-governance]

  * [BYOK provider credentials](/guides/byok-setup) and subscription credentials (Claude Code, ChatGPT Codex). Raw tokens are fingerprinted and discarded; only the fingerprint, provider, and plan label are retained.
  * Provider keys at rest are sealed with AES-256-GCM and opened only at execution time.
  * GDPR and CCPA tooling: machine-readable [data export](/security/gdpr-ccpa), an erasure flow with signed receipts, a published sub-processor list, and per-project Do-Not-Sell preferences.
  * Per-project [regional policy](/security/data-privacy-and-retention) and retention profiles.
</Update>

<Update label="2026-06-01" description="Native state and reproducibility">
  ## /v2 stateful API [#v2-stateful-api]

  * [Artifacts](/concepts/artifacts), [bundles](/concepts/bundles), [sessions](/concepts/sessions), and append-only [branches](/concepts/branches) with optimistic concurrency.
  * [Snapshots](/concepts/snapshots) that pin ordered logical state for a branch head.
  * Immutable [model alias releases](/concepts/model-aliases) and per-response resolution records.
  * [QoS outcomes](/concepts/qos), the [agent-hints contract](/concepts/agent-hints), idempotency and attempt lineage.
  * [Purge jobs and signed receipts](/concepts/retention-and-purge) with profile-specific guarantee classes.
</Update>

<Update label="2026-05-15" description="Provider-first diagnostic platform">
  ## Initial launch [#initial-launch]

  * Exact OpenAI-compatible [`/v1`](/openai-compatibility): responses, chat completions, embeddings, and models.
  * Managed-provider execution across OpenAI, Anthropic, xAI, Google Gemini, and Fireworks AI through the Bifrost gateway.
  * Trace capture, the [Workload Reuse Score](/concepts/workload-reuse-score), and the opportunity-versus-realized-reuse [diagnostic](/guides/workload-diagnostics).
  * Project auth, API keys, quotas, and usage telemetry.
