 # mlr3 0.13.4
 
+* Added new options for parallelization (`"mlr3.exec_random"` and
+  `"mlr3.exec_chunk_size"`). These options are passed down to the respective map
+  functions in package `future.apply`.
 * Fixed runtime measures depending on specific predict types (#832).
 * Added `head()` and `tail()` methods for `Task`.
 * Improved printing of multiple objects.
