+
+`paths` and `routes` now track the current Relay API. Three endpoints are gone, request
+amount fields are nullable, and deposit addresses, fee sponsorship and route racing gained
+new options.
+
+**Breaking**
+
+- `/execute/swap`, `/requests/{requestId}/signature` and `/requests/{requestId}/signature/v2`
+  are removed from `paths` and from the exported `routes` array. Quotes come from
+  `POST /quote/v2`. `SwapBreakdown` and `Execute['breakdown']` are unchanged — the SDK now
+  declares that shape directly instead of deriving it from `/execute/swap`.
+- On `GET /requests/v2` and `GET /requests/v3`, amount-bearing fields are now `string | null`
+  rather than `string | undefined`: `appFees[]` / `paidAppFees[]` (`recipient`, `bps`,
+  `amount`, `amountUsd`, `amountUsdCurrent`), `data.fees.*` (`usd`, `amount`,
+  `amountFormatted`) and `data.route.*` currency amounts (`amount`, `amountFormatted`,
+  `amountUsd`, `minimumAmount`). This reaches `useRequests`, `queryRequests` and
+  `useDepositAddressStatus`. Passing one of these into a `string | undefined` slot no longer
+  compiles — use `?? undefined`, or widen the receiving type to accept `null`.
+- `ChainVM` gains `'hederavm'`. An exhaustive `switch` over `ChainVM` with a `never`
+  fallthrough needs the new case.
+- `GET /config/v2` no longer accepts `currency: "degen"` or `"usdh"`, and `GET /prices/rates`
+  no longer returns `DEGEN`. Remove references to those literals; `"ausd"` is now accepted.
+
+**Added**
+
+- `GET /deposit-addresses/v2` returns a deposit address with its `deposits` and `sweeps`
+  history, and `POST /deposit-addresses/{depositAddressId}/disable/v2` disables one.
+  `/quote` and `/quote/v2` responses now carry `requestId` and, on deposit-address steps,
+  `depositAddressId`.
+- Quote request options: `subsidizationBps` (share of each sponsored fee component the
+  sponsor covers, applied before `maxSubsidizationAmount`), `indicativeQuote`,
+  `referencePrice`, `useRouteRacing` and `routeRacingMinUsdSize`. `subsidizationBps` is
+  echoed back in `feeSponsorship` on quotes and requests.
+- `GET /requests/v3` accepts a `referrer` filter (requires `apiKey`) and returns `apiKeyName`
+  and `blockedAddresses` to the request's creator integrator. `GET /requests/v2` responses
+  carry a `deprecation` block with its sunset and successor.
+- `MANUAL_REFUND_REQUIRED` joins `refundFailReason`; `GET /intents/status/v3` now reports
+  `failReason` and `refundFailReason`; `GET /withdrawals/status` returns `txHash`;
+  `hederavm` joins the chain VM types.
+
+**Deprecated**
+
+- The `strict` quote parameter is ignored by `/quote/v2`; deposit-address creation follows
+  the requested trade type.
