@@ -75,6 +75,12 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Bump `@metamask/controller-utils` from `^11.19.0` to `^11.20.0` ([#8344](https://github.com/MetaMask/core/pull/8344))
 - Bump `@metamask/messenger` from `^1.0.0` to `^1.1.0` ([#8364](https://github.com/MetaMask/core/pull/8364))
 
+### Removed
+
+- **BREAKING:** Remove `adaptMarketFromMYX`, `adaptPriceFromMYX`, `adaptMarketDataFromMYX`, `filterMYXExclusiveMarkets`, `isOverlappingMarket`, `buildPoolSymbolMap`, `buildSymbolPoolsMap`, and `extractSymbolFromPoolId` from the public package exports to prevent `@myx-trade/sdk` from being included in the static webpack bundle ([#8374](https://github.com/MetaMask/core/pull/8374))
+  - These functions are still used internally by `MYXProvider`, which is loaded via dynamic import
+  - Consumers that imported these utilities directly should instead import from `@metamask/perps-controller/src/utils/myxAdapter` or duplicate the logic locally
+
 ### Fixed
 
 - Fix incorrect fee estimate when flipping a position ([#8333](https://github.com/MetaMask/core/pull/8333))
