## 1.1.0 — 2026-05

**Token-based metering**

* New `tex.usage.today()` and `tex.usage.summary(month=...)` methods.
* Every `remember` and `recall` response now carries a `usage` field with `tokens_in` and `tokens_out`.
* Daily quotas enforced at the engine. Exceeding them raises `RateLimitError`.

**Conversation-native verbs**

* `tex.conversations.remember(turns=..., session_id=...)` for first-class turn ingestion.
* `tex.recall(q=..., session_id=..., mode="active"|"deep")` with confidence scoring and optional timeline.

**Improvements**

* HTTP/2 enabled by default for \~25% lower tail latency on recall.
* Automatic JWT refresh on 401, with single-retry semantics.
* Stable type stubs (`py.typed`) shipped with the wheel.

## 1.0.0 — 2026-03

Initial public release. Supermemory-compatible verbs (`add`, `search`, `profile`).
