Jul 1, 2025July 2025 (mlr3pipelines, mlr-org/mlr3pipelines): Key features delivered, bugs fixed, and value delivered through a focused release cycle. Delivered Release 0.9.0 with imputation improvements for factor and ordered features, plus paradox compatibility adjustments, and a version bump to 0.9.0. Reverted debugging changes that affected preproc examples to restore stable preproc.R and man/preproc.Rd behavior. Fixed documentation inconsistencies, correcting a typo in PipeOpImputeOOR.R and updating PipeOpImpute.Rd to reflect the parameter rename from create_empty_levels to create_empty_level. These changes enhance reliability, API consistency, and onboarding, supporting faster adoption of imputation enhancements while reducing maintenance overhead. Technologies and skills demonstrated include R packaging practices, documentation tooling, and robust release engineering, with careful changes to code and docs to ensure API stability and user-facing clarity.
