# Changelog

Track baseline releases and documentation changes across the Polaris Labs product suite.

## Drift 0.3.1

- Documented the `expiresAt(key)` deadline-inspection method, which returns the
  absolute Unix-epoch expiry timestamp in milliseconds (or `undefined` for
  absent, expired, or permanent entries) without changing LRU recency.
- Expanded the `ttl(key)` description to clarify its `undefined` return
  conditions and that it does not affect LRU recency.
- Updated the [store method reference](/api/store-methods) and
  [Drift concepts](/drift/concepts) pages.

## Flagpole 1.1.0

- New public `GET /ready` deployment probe returns
  `{ "status": "ready", "version": "1.1.0" }` without credentials, joining
  `GET /health` and `GET /version` as unauthenticated service probes.
- All service probes now report version `1.1.0`.
- Updated the [API overview](/api/introduction),
  [API reference](/guides/flagpole-api), [quickstart](/flagpole/quickstart),
  [configuration](/customization), and [OpenAPI spec](/api) to reflect the
  new endpoint and version.

## Documentation baseline

The first suite-wide baseline documents both current product releases and the
workflow that combines them.

- Flagpole `1.0.0`: health and version probes, paginated flag reads, status
  and rollout projections, percentage rollouts, tags, history, environments,
  and webhook delivery records.
- Drift `0.2.0`: typed stores, TTL and LRU behavior, persistence, namespaces,
  lifecycle events, collection reads, batches, and rollback-on-error
  transactions.
- Shared guide: cache Flagpole evaluation responses in Drift with a short TTL.

Future entries should describe the reader-visible result and link to the
updated concept, guide, or reference page.
