Changes in version 1.0.8 (2026-05-18) - Updates to CRAN maintainer. - Fixes testing bug checking that multicore evaluation is not significantly slower than sequential as detected by CRAN automated checks. Changes in version 1.0.7 (2022-10-19) - Removal of unused import future::values given its deprecation. Changes in version 1.0.6 - Fixes to stratified cross-validation bugs. - More informative warnings when n (sample size) is less than or equal to V (number of folds). Changes in version 1.0.5 (2021-09-28) - Addition of glmnet to package Suggests since used in the vignette. - Resolve issue stemming from the partial matching of argument names (https://github.com/tlverse/origami/issues/56) by specifying throughout. Changes in version 1.0.4 - Fix the incorrect use of future.apply by including future.seed = TRUE, as per https://github.com/tlverse/origami/issues/48. - Fixes to folds_rolling_origin_pooled and folds_rolling_window_pooled, as per https://github.com/tlverse/origami/pull/50. - Sped up all pooled time-series fold functions with lapply. - All pooled time-series fold functions (folds_rolling_origin_pooled, folds_rolling_window_pooled, folds_vfold_rolling_origin_pooled, folds_vfold_rolling_window_pooled) now allow for variability in the number of observations for each independent unit (i.e., the subject). - Added test for pooled time-series cross-validation with multi-unit time-series to test the update above. In this test, the total number of observations and the time-points for which there are observations varies across the units. Changes in version 1.0.3 (2020-01-16) - A maintenance release addressing reported issues, including changes to unit tests that relied on Suggested packages dependencies. Changes in version 1.0.2 - Adds new functionality for cross-validation with time-series, especially functionality for pooling time-series data. This includes the new functions folds_rolling_origin_pooled, folds_rolling_window_pooled, folds_vfold_rolling_origin_pooled, folds_vfold_rolling_window_pooled. Changes in version 1.0.1 (2019-05-01) - Adds a simple check of the current R version in the unit tests in the file tests/testthat/test-overall.R to use appropriate hard-coded values that depend on the R version. Note that these differ between R < 3.6.0 and R > 3.6.0 due to an important change in the default PRNG. Changes in version 1.0.0 (2018-03-06) - Adds a new function folds2foldvec for easy conversion between the folds structure used by origami and other packages (e.g., glmnet). - Adds an option to use lapply instead of future_lapply, for compatibility with other packages in a custom parallelization framework. - Calls future_lapply from the new more modular package future.apply rather than from future, matching the author's recommendation. Changes in version 0.8.0 (2017-06-23) - First CRAN release. - Removed origami_SuperLearner functionality temporarily.
