 - added switches `--fk-table-fac0` and `--fk-table-frg0` to `pineappl read` to
   read out the squared factorization and fragmentation scales of FK-tables
+- C API: added new functions `pineappl_channels_new` and `pineappl_channels_delete`
+  to create and delete an instance of `Channels` object
+- C API: added `pineappl_grid_channels` and `pineappl_channels_count` to get
+  the channel objects for a given grid and their numbers
+- C API: added a function `pineappl_channels_combinations` to retrieve the
+  number of combinations of channels for a specified entry, and

+- C API: added new functions to fill grids with an arbitrary number of
