I did already.  And it reads

Clients that supports progress reporting:
* The mysql command line client, starting from version 15.0 (comes with MariaDB 5.3). 
* mytop which comes with MariaDB 5.3 has a '%' column that shows the progress.

It does not list the C-API.  maybe you should add "Clients compiled with the C-API as shipped with MariaDB 5.3+ provided that ... ". It it not all that the command line supports that is suppored in API (examples: \G-delimiter and SOURCE statement for instance) so listing CLI does not necessary. 

Now I have read 'deeper' and it looks like C-API is working too.  But I think it should be listed explicitly if supported.
