+- Add the skip swap adapter that can be triggered to request token swaps on local or remote chains via IBC + PFM + Hooks, using Skip swap contracts. ([\#361](https://github.com/informalsystems/hydro/pull/361))
+- Add `ControlCenterPoolInfo` query to the Inflow vault contract that returns the pool info from the Control Center contract. ([\#363](https://github.com/informalsystems/hydro/pull/363))
+- Clean-up validators info from the LSM token info provider store in case of validator unbonding. ([\#370](https://github.com/informalsystems/hydro/pull/370))
