Code that depended on inputs being merged into the target through alias must now pass copies explicitly. The documented 'update the target' behavior is preserved on the target itself. * - DeepMergeMetaMetaData has been renamed to DeepMergeMergeInfo. Imports must be updated. - The MetaDataUpdater callback's `metaMeta` parameter is now `mergeInfo`. Implementations must update the parameter name accordingly. - The MM generic shorthand has been renamed to MI (e.g. in `MetaDataUpdater`). * The `DeepMergeIntoFunctionUtils` type has been renamed to `DeepMergeIntoUtils`. * Updates the internal calculation logic for mergeMaps and mergeMapsInto.
