> What shipped, and when.

<Update label="2026-04-17" description="SMS Phase 3">
  * **Multi-country routing.** Send to NG, GH, KE, CI through one API with per-country pricing and automatic country detection from E.164. [Guide](/sms/multi-country)
  * **Provider failover.** Added Termii as a Nigerian fallback to Beem. Every send records `provider_attempts` showing exactly who we tried.
  * **Python + Go SDK parity.** `pm.sms.*`, `pm.sender_ids.*`, `pm.sms_templates.*` now exposed with typed request/response structs in both languages.
</Update>
