# Changelog

> Product updates and what we're shipping.

<Update label="March 7, 2026" tags={["API", "iMessage"]}>
  **Leased Number Configuration** — You can now configure leased numbers using the Lease API, including customizing failover behavior. [Learn more](/api-reference/product/leases/configure)
</Update>

<Update label="March 1, 2026" tags={["API"]}>
  **iMessage Link Preview** — Fixed some links not rendering/appearing as text in messages. Now, if a user has your number saved as a contact, or have interacted with you before, they'll see a rich link preview. If they don't have your number saved, they'll see the link preview, after clicking the "touch to load" button.

  **Error handling improvements** — When SMS fallback is unavailable (for example, when your <code>fallback.from</code> does not support SMS).

  **Get iMessage Availability** — You can now query live iMessage availability for a destination. Requires a leased iMessage-capable number to be eligible. [Get iMessage Availability](/api-reference/product/imessage/availability)

  **Contiguity Voice** — Coming to more customers soon. Docs and edge-case fixes in progress.

  **Onboarding latency** — Initial load reduced by 6x.

  **Incoming Emails** — Verify a domain, set a webhook URL, receive incoming emails. Free and unlimited during beta.

  **Console** — High-volume senders: "recent messages" tables now support pagination. Uptime visibility in the sidebar so you can see if Contiguity is having issues.

  **Message tracking (early beta)** — Updates at each hop, API to device.

  **Python SDK v2** — Shipped. Docs coming soon.

  **Uptime visibility** — See status directly in the Console.

  **API errors** — Will return links to relevant docs when available.

  **Risk calculation** — Revamped; accuracy improved \~30% using real-world Console data. More transparent (what contributed to your score, similar to Stripe's fraud risk visuals).

  **MMS shipped early** — Public beta, no entitlements required. [MMS docs](/api-reference/product/text/mms)

  MMS supports longer messages — up to 1500 characters before splitting (no more 160-character chunks). Billing for MMS is still being finalized; currently priced as text.
