+    to be active before the call — e.g.,
+    `future::plan(future::multisession)` — and throws an informative
+    error if none is set.
+  - New all-core usage setup: when the number of AB columns is smaller
+    than the number of available cores, rows are now split into batches
+    so all cores stay active (row-batch mode). Previously, a 6-column
+    dataset on a 16-core machine would only use 6 cores; now all 16 are
+    used, with each worker processing a smaller row slice (lower
