Maintenance release with planned changes and deprecations. Users should note completed deprecations and consult notes below. Please see our changelog for a description of all changes. Deprecations and removals Estimator Tags for multiple estimator types The deprecated ignores-exogeneous-X tag for forecasters has been removed. It has been replaced by capability:exogenous. The logic of the tag is flipped, i.e., if capability:exogenous=True, the estimator can handle exogenous variables. The deprecated univariate-only tag present in multiple estimator types has been removed. It has been renamed to capability:multivariate, with boolean flip. If capability:multivariate=True, the estimator can handle multivariate data. Users and maintainers of third party estimators should update their code and estimators to use the new tags. Forecasters The deprecated scitype:y tag present in forecasters has been removed. It is renamed to capability:multivariate. If capability:multivariate=True, the estimator can handle multivariate data, if False, it cannot. Values of the old tag map as follows onto the new tag: "univariate" maps onto False, "multivariate" and "both" map onto True. Users and maintainers of third party estimators should update their code and estimators to use the new tag. The deprecated legacy API for global forecasting (y in predict) has been removed. Users should use the new global forecasting API through pretrain. The capability:global_forecasting tag is deprecated and will be removed entirely in version 1.2.0; until then, access will raise a warning. Users should use the capability:pretrain tag instead.Tag queries will not be redirected due to simultaneous presence of both tags in versions prior.
