This files describes API changes for question import/export format plugins.

=== 2.2 ===

* The plugin name used to be defined in a string called the same thing as the
format, with assoicated help strings, for example:

$string['aiken'] = 'Aiken format';
$string['aiken_help'] = 'This is a simple format ...';
$string['aiken_link'] = 'qformat/aiken';

This needs to be changed to use the standard string name pluginname, as for
other plugin types.

$string['pluginname'] = 'Aiken format';
$string['pluginname_help'] = 'This is a simple format ...';
$string['pluginname_link'] = 'qformat/aiken';
