 ## Changelog
 
+- **v1.2** (2026-06-14) — Removed 16 maker/taker terminal-PnL columns
+  (`pnl_maker_total`, `pnl_taker_total`, and their per-category siblings)
+  from `user_pnl_summary`. These were shipped undocumented in v1.1 and the
+  per-category role columns did not recombine to the base per-category
+  totals for users who acted as both maker and taker (≈17.5% of users), so
+  they have been withdrawn. The five documented variants (base, resolved,
+  no-fee, spread-adjusted, spread-adjusted resolved-only), their
+  per-category breakdowns, and the `portfolio_value` / `usdc_balance`
+  decomposition are unchanged. No other table is affected. A user's
+  maker-vs-taker activity is still fully recoverable from the `trades`
+  table (each row carries `maker_address` and `taker_address`); see the
+  [documentation](https://www.vincentgregoire.com/polymarket-users-data)
+  recipes.
