The changes committed under SERVER-91195 introduced a clonable format for "special" timeseries catalog options that were not properly cloned in previous [sub-]versions (e.g. timeseriesBucketsMayHaveMixedSchemaData).
This enabled the possibility of resharding collections with such option (previously failing with CannotInsertTimeseriesBucketsWithMixedSchema), with the wrinkle that migrations will now only clone the new format. Because of that, tests checking for timeseriesBucketsMayHaveMixedSchemaData should be adapted to take into account the new format (this is an example).
