+## Changelog
+
+### v0.3.1 (2026-04-12)
+
+- **feat**: `order` — new `--leverage <N>` flag (1–100) sets account-level leverage for the coin before placing the order via `updateLeverage` action; fixes the UX gap where users specifying 10x leverage would silently get the account default (e.g. 20x)
+- **feat**: `order` — new `--isolated` flag to use isolated margin mode when `--leverage` is set (default is cross)
+- **fix**: `withdraw` — add $1 USDC fee notice in preview and output; balance check now validates amount + $1 fee; minimum withdrawal error changed from warning to bail
