 ### Backward-compatibility notices:
+* Version 2.16.03 moved the position of the log-file name to the last column in the CSV output of `utils/bin/yask_log_to_csv.pl`.
 * Version 2.15.04 required a call to `yc_grid::set_dynamic_step_alloc(true)` to allow changing the
 allocation in the step (time) dimension for grid variables created at YASK compile-time.
 * Version 2.15.02 required all "misc" indices to be yask-compiler-time constants.
