Custom Icons via simple_social_default_glyphs filter disappeared

Hello,

I basically created a function using the simple_social_default_glyphs filter to add custom theme icons and now they are gone since the update.

Here’s what it looked like:

add_filter( 'simple_social_default_glyphs', 'ppdn_simple_social_icons_glyphs' );
function ppdn_simple_social_icons_glyphs( $glyphs ) {
	$glyphs = array(		
 		'email'       => '<span class="ppd-email-alt"></span><span class="screen-reader-text"></span>',
 		'facebook'    => '<span class="ppd-facebook"></span><span class="screen-reader-text"></span>',		
 		'gplus'       => '<span class="ppd-google-plus"></span><span class="screen-reader-text"></span>',		
 		'linkedin'    => '<span class="ppd-linkedin"></span><span class="screen-reader-text"></span>', 		
 		'rss'         => '<span class="ppd-rss"></span><span class="screen-reader-text"></span>',		
 		'twitter'     => '<span class="ppd-twitter"></span><span class="screen-reader-text"></span>',
 		'youtube'     => '<span class="ppd-youtube"></span><span class="screen-reader-text"></span>',
 	);

 	return $glyphs;
}

But now it isn’t working anymore. The actual default icons have replaced them since the update. Any thoughts?

Thanks in advance,

Rich
