<Update label="New Markets: To Advance, Player Games Won, and Soccer Alts">
  New market types are available on **QA** as of June 29, 2026, and will be rolled out to **Production** by Tuesday, June 30, 2026.

  **New market types:**

  * `TO_ADVANCE` - Which team advances to the next round (FIFA World Cup)
  * `PLAYER_GAMES_WON` - Tennis player total games won in a match (ATP, WTA)

  **Expanded markets:**

  * `SPREAD` and `TOTAL` alternates are now offered across all soccer leagues
</Update>

<Update label="June 17, 2026 - Scheduled Deployment Tonight">
  Hey everyone, we'll be doing a deployment tonight starting around 1AM EDT. We'll cancel open orders before resuming trading.
</Update>

<Update label="June 2, 2026 - Scheduled Downtime & Tick Table Reminder">
  We will be deploying critical infrastructure updates tomorrow (June 2) at 9:00 AM eastern. We expect approximately 1 hour of downtime.

  **Separate Reminder:** The deadline for the new tick table has passed. We have not yet started rejecting orders on invalid ticks, but will be doing so soon and with minimal notice — please get your implementation across the line ASAP.

  If you have any questions about the tick table please do not hesitate to reach out.
</Update>

<Update label="May 8, 2026 - GET /markets/{marketId} Works for Settled Markets">
  You can now call `GET /nbx/v2/emm/markets/{marketId}` for markets that have already settled. The response includes `settledAt` and the outcomes' `WIN`/`LOSS` statuses, so you can look up final results without needing to capture them while the market was still open.
</Update>

<Update label="May 8, 2026 - Higher Rate Limits & Page Size for User History Endpoints">
  We've raised the limits on the user history endpoints:

  * **Burst:** 16 requests/second (up from 5)
  * **Sustained:** 256 requests/minute (new, smoothed over 60s)
  * **Page size (`limit` parameter):** max 256 items per request (up from 100)

  **Affected endpoints:**

  * `GET /nbx/v2/emm/fills/all`
  * `GET /nbx/v2/emm/orders/all`
  * `GET /nbx/v2/emm/transactions`

  A note on last week's change: Last week's rate-limit adjustment broke things for some of you and we're sorry about that. The new burst + sustained limits above should give you a lot more room to work with. Going forward, any rate limit change will be announced in our changelog with enough lead time for you to adjust.
</Update>

<Update label="May 8, 2026 - Tick Table Endpoint & Price Validation">
  A new REST endpoint is available for fetching the canonical set of valid order prices (ticks).

  **New endpoint:**

  * [`GET /nbx/v2/emm/ticks`](/api-reference/ticks) - Fetch the full tick table

  Orders must be priced at a valid tick; submissions at off-tick prices will be rejected.

  **Migration cutover: June 1, 2026.** Until then, previously valid prices will continue to be accepted. After June 1, only tick-table prices will be accepted.

  **Market makers should fetch the tick table dynamically and not hardcode it**, as the table may change in the future. See the [Tick Table](/api-reference/ticks) page for details.
</Update>

<Update label="April 2, 2026 - New Strike Request Endpoint">
  A new REST endpoint is now available for requesting new strikes on existing markets.

  **New endpoint:**

  * [`POST /nbx/v2/emm/strike-requests`](https://docs.novig.com/api-reference/markets/request-new-market-strike) - Request a new strike for an existing market

  Submit a `marketId` and `strike` value to notify the Novig team. Whole number strikes (e.g. `300`) are automatically converted to half-point strikes (e.g. `300.5`). A successful response does **not** guarantee the market will be created.
</Update>

<Update label="New Events REST Endpoints Available">
  New REST endpoints for fetching events and markets are now available on both **Production** and **QA** environments. These endpoints provide a simpler alternative to GraphQL for event discovery and market data.

  **New endpoints:**

  * `GET /nbx/v2/emm/events` - List events with filters
  * `GET /nbx/v2/emm/events/{eventId}` - Get a single event
  * `GET /nbx/v2/emm/events/getMarketsByEvent/{eventId}` - Get markets with orderbook data
  * `GET /nbx/v2/emm/event-metadata/leagues` - List available leagues
  * `GET /nbx/v2/emm/event-metadata/types` - List event types
  * `GET /nbx/v2/emm/event-metadata/statuses` - List event statuses

  If you're currently using GraphQL for event queries, see our [GraphQL to REST Migration Guide](migration-guides/graphql-to-rest-events) for detailed migration instructions.

<Update label="Upcoming Change to EMM Authentication">
