Review details

Suppressed comments (1)

src/wp-includes/widgets.php:1641

• This change is specifically about the number and timing of get_option() calls, but there is no regression test for that behavior. Please add a test with multiple RSS items that counts blog_charset and date_format option retrievals, including the show_date-disabled path, so the optimization cannot silently regress to per-item calls.

	$blog_charset = get_option( 'blog_charset' );
	$date_format  = $show_date ? get_option( 'date_format' ) : '';
