+All `World` methods acting on namespaces as resources have been updated to use `ResourceId namespaceId` as parameter instead of `bytes14 namespace`.
+The reason for this change is to make it clearer when a namespace is used as resource, as opposed to being part of another resource's ID.
+
+```diff
++ import { ResourceId } from "@latticexyz/store/src/ResourceId.sol";
+
+IBaseWorld {
+- function registerNamespace(bytes14 namespace) external;
++ function registerNamespace(ResourceId namespaceId) external;

+- function transferOwnership(bytes14 namespace, address newOwner) external;
++ function transferOwnership(ResourceId namespaceId, address newOwner) external;

+- function transferBalanceToNamespace(bytes14 fromNamespace, bytes14 toNamespace, uint256 amount) external;
