What changed, when, and whether you need to care. Breaking changes get 90 days' notice and a migration snippet — that's a promise, not a roadmap item.
invite links
Team-invite and workspace-join links are now classified alongside magic_link, verification, and unsubscribe. No SDK update needed — it's a new value, not a new field.
For apps that batch their outbound mail. The default stays 30s; passing timeout: 60_000 no longer 400s. Existing tests are unaffected.
Emails that mention a phone number, an order ID, and a one-time code sometimes extracted the wrong digits. The classifier now weighs label proximity and formatting; the reported-case pass rate went from 94.1% to 99.97%. Thanks to the three of you who sent raw MIME samples.
POST every received message to your endpoint, signed with your webhook secret. Retries with backoff for 24h. Long-polling is still the right tool inside a test; webhooks are for everything around it.
pip install mailfixture. Sync and async clients, pytest fixtures included (@pytest.fixture def inbox — yes, a fixture fixture). API parity with the Node SDK.
GET /v1/poll (v0 endpoint)
The pre-1.0 polling endpoint sunsets Aug 1, 2026 — 90 days from this notice. Migration is one line: replace it with GET /v1/inboxes/:id/wait. Both SDKs did this for you in 0.9.
