## 2026-07-25 - Full and partial combo redemption lineage

Added dedicated combo redemption endpoints without changing existing position
or activity responses.

What's new:

* `GET /v3/combos/redemptions` returns canonical combo redemption and reduction
  history across wallets.
* `GET /v3/wallets/{address}/combos/redemptions` returns the same history for
  one wallet.
* Every row identifies `redemption_scope` as `full`, `partial`, or
  `transformation` and exposes its supporting `redemption_evidence`.
* Full redemptions map automated redemption activity to the actual user and
  combo position.
* Partial reductions expose source, destination, removed, remaining, parent,
  and child identifiers, with `leg_transition` values such as `5_to_1`.
* When canonical market metadata exists, enriched legs include token, result,
  and current-price fields. Permissionless legs retain their exact position ID
  without guessed market fields.
* Filters cover wallet, condition, position, event kind, scope, transaction
  hash, and time range.

## 2026-07-24 - Clearer WebSocket and RPC capacity limits

Updated the public limit contract so client connection planning is distinct
from subscription planning.

What's clarified:

* A WebSocket physical-connection allowance is separate from the number of
  logical subscriptions and filters multiplexed over each connection.
* Requests authenticated by a member-owned API key use that key's own plan
  limits rather than a shared platform key's allowance.
* Eligible paid API keys can use the documented Polygon RPC allowance of 50
  requests per second.
* Existing endpoint, message, and authentication formats are unchanged.

## 2026-07-22 - polynode is now part of Agg

polynode joined Agg and continues as a standalone product for Polymarket data
customers.

What this means for customers:

* Existing API and WebSocket domains, endpoints, API keys, SDK workflows, and
  documentation remain available. No client migration is required.
* Current plan names and pricing remain in place, and the product stays open
  to all builders.
* The product focus remains faster maintenance, stronger reliability, and
  broader data coverage.

## 2026-07-21 - Query trades by order hash

V3 trade feeds can now return every fill associated with one exact Polymarket
order hash.

What's new:

* Use `order_hash` on `GET /v3/trades`,
  `GET /v3/wallets/{address}/trades`,
  `GET /v3/markets/{token_id}/trades`, and
  `GET /v3/markets/slug/{slug}/trades`.
* Wallet queries can combine the hash with maker/taker role, token, condition,
  market, event, time, and amount filters. Filtering occurs before pagination.
* `group_by=order_hash` and `sort_by=order_hash` work consistently across the
  global, wallet, market-token, and market-slug routes.
* A valid hash with no matching fills returns an empty page. A malformed hash
  returns HTTP `400`.
* Combo trades do not expose a Polymarket order hash, so combining
  `order_hash` with `include_combos=true` returns HTTP `400`.

## 2026-07-21 - Clearer subscription expiry and resubscription

Updated how the dashboard handles an earlier paid subscription after its
recorded access period ends.

What's changed:

* Paid access moves to the Free plan at the recorded end time rather than
  remaining indefinitely on an expired subscription.
* Existing API keys remain active and adopt Free-plan access and limits.
* A Free account sees **Subscribe** in Settings and is sent to current pricing,
  even when the account retains an older billing reference.
* A newer active subscription or another valid paid-access method takes
  precedence, so an old expiry cannot overwrite current access.
* Delayed billing events from an earlier subscription cannot overwrite a newer
  successful resubscription.

## 2026-07-20 - Updated card checkout and billing portal

Moved new card purchases to the current polynode subscription catalog while
preserving active access and in-progress checkouts during the transition.

What's improved:

* Starter, Growth, and Enterprise purchase buttons open the current card
  checkout for the published plan and price.
* The Starter plan retains its three-day trial.
* A checkout opened from an older browser session is translated to the
  corresponding current plan instead of failing on an outdated reference.
* Customers with an active subscription are sent to the correct billing portal
  instead of creating a duplicate Checkout.
* Existing paid access remains valid through its recorded paid-through period.
