Fatal error with last version

Hi,

With last version we get this error on several websites:

Fatal error: Uncaught Error: Call to undefined function register_block_style() in /home/wp-content/plugins/wp-accessibility-a/wp-accessibility-longdesc.php:176 Stack trace: #0 /home/wp-content/plugins/wp-accessibility-a/wp-accessibility.php(44): require_once() #1 /home/wp-admin/includes/plugin.php(1897): include('/home/...') #2 /home/wp-admin/plugins.php(172): plugin_sandbox_scrape('wp-accessibilit...') #3 {main} thrown in /home/wp-content/plugins/wp-accessibility-a/wp-accessibility-longdesc.php on line 176

We rollback to previuos version.
