About mlr3
mlr3 is hardening the seams where its abstractions meet real learners
Releases arrive every few weeks and read as a systematic audit of the Learner interface. Recent versions added a native_model binding and a predict_raw flag so users can reach the underlying package's model and raw prediction, gave encapsulated learners a wall-clock deadline alongside the existing timeout, and removed the deprecated Task$divide(). A run of fixes addresses correctness at the boundary - factor level ordering that inverted binary probabilities, fallback learners losing state, misaligned probability columns.
