tfoWe recently built a WordPress site based on the Sandbox theme. I just noticed that we now have two link tags referencing Comments RSS in head. One of them seems to be created by the call to wp_head(). I can't find any plug-ins that are activated that are creating the extra one. This line exists in header.php in our theme:
<link rel="alternate" type="application/rss+xml" href="<?php bloginfo('comments_rss2_url') ?>" title="<?php echo wp_specialchars(get_bloginfo('name'), 1) ?> <?php _e('Comments RSS feed', 'sandbox'); ?>" />
Did Comments RSS move into core in a recent release? I can't find mention of that, but I'm also having trouble tracking down why wp_head() would be generating a reference to comments_rss2_url but not rss2_url.
