Three additions to the checks every send passes through. The full list, in
order, is now at [Compliance checks](/docs/compliance-checks).

- **Quiet hours.** A marketing message outside 8:00am to 9:00pm in the
  recipient's local time (read from the area code) is refused with
  `403 quiet_hours`, or held until 8:00am with `"quiet_hours": "defer"`.
  Broadcasts, batches, recurring schedules and automations hold by default,
  recipient by recipient.
- **`category`** (`marketing`, `transactional`, `otp`) on
  `POST /v1/messages`, batches and schedules. Without it, broadcasts and
  numbers registered for Marketing are marketing and everything else is
  transactional, so codes, receipts and alerts are unaffected.
- **Who will notice.** If you send from a number registered for the
  Marketing use case, or send broadcasts, messages that fall in a
  recipient's quiet hours are now refused or held. Turn the check off in
  Console → Compliance if you handle quiet hours yourself.
- **Blocked messages are in your log.** Every send we refuse (opted out,
  quiet hours, unregistered sender, content, allowance, spend limit,
  credits) is stored with `status: "blocked"` and a `failure` reason,
  and is never charged. `GET /v1/messages?status=blocked`,
  `blocked_reason` and `failure_code` filters, a Blocked filter in
  Logs, and `reason` columns in the CSV export.
- **`message.blocked`** now fires for every blocked send, not only
  opt-outs, and carries `message_id`. New event: `message.deferred`.
- **Bring your opt-outs.** A migration now asks for the opt-out list from
  your previous provider, or your confirmation that there is none, before it
  runs. See [Opt-out](/docs/opt-out#bring-your-opt-outs).
- Sandbox: `+15005550015` is always in quiet hours.
- Node and Python SDKs 2.4.0: `category` and `quietHours`
  (`quiet_hours` in Python) on `messages.send`, the `quiet_hours`
  error code with `sendAfter`, and the `blocked` status.
