<Update label="Week of August 3, 2026">
  ## Breaking changes

  * **[`kalshi.ohlcv_hourly`](/data-catalog/curated/prediction-markets/kalshi/ohlcv_hourly): candles stop at settlement.** Forward-filled candles after settlement are removed and `market_end_time` now marks the final candle. Update queries that relied on post-settlement rows.&#x20;
  * **[`polymarket_polygon.market_details`](/data-catalog/curated/prediction-markets/polymarket/market_details): columns retyped.** Eleven `varchar` columns become native booleans, timestamps, integers, and arrays; the Snowflake datashare follows. Remove text casts, and markets previously dropped by the type mismatch reappear in [`polymarket_polygon.ohlcv_hourly`](/data-catalog/curated/prediction-markets/polymarket/ohlcv_hourly). &#x20;
  * **Stablecoin tables are now a premium dataset.** Free public access to the [`stablecoins_*`](/data-catalog/curated/stablecoins/overview) schemas ended on August 3; provisioned teams are unaffected.&#x20;

  ## Fixes

  * **[`polymarket_polygon.market_trades`](/data-catalog/curated/prediction-markets/polymarket/market_trades): missing trades restored.** Trades on tokens the original exchange contracts never listed were dropped; historical volumes from late June onward revise upward.&#x20;
  * **[`tokens_xrpl.transfers`](/data-catalog/curated/token-transfers/xrpl/xrpl-token-transfers): issued-token transfers complete.** Every successful issued-token balance change is now covered (payment paths, offers, AMMs, issuance, redemption); holder histories change.&#x20;
</Update>

<Update label="Week of July 27, 2026">
  ## Deprecations

  * **`tokens_{chain}.balances_daily_agg` removed.** Replaced by the premium [`balances_<chain>`](/data-catalog/curated/balances/overview) dataset ([`latest`](/data-catalog/curated/balances/evm-latest), [`updates`](/data-catalog/curated/balances/evm-updates), [`daily_updates`](/data-catalog/curated/balances/evm-daily-updates)), which carries a different schema. Migrate queries that reference the removed tables.&#x20;

  ## Methodology

  * **Stablecoins: finer entity subcategories.** [`address_subcategory`](/data-catalog/curated/stablecoins/balances-enriched/stablecoins-evm-balances-enriched) now distinguishes custodians, prime brokers, market makers, derivatives exchanges, issuers, lending desks, and wallet providers instead of a single `cex` bucket; aggregations grouped by subcategory shift. &#x20;

  ## New data & improvements

  * **Entity labels: enriched address dataset.** The new `entity_labels_evm.addresses_enriched` table serves one row per address with the owner's identity inline, including wallet-level `role_tags`, so reading a label needs no join.&#x20;
