 Severity:  normal        |   Keywords:

--------------------------+-----------------------------
 Tested on clean install of WP 3.9 beta 2 with no plugins activated.

 '''Case 1: previous_post_link/next_post_link returns nothing when
 "in_same_cat" parameter is true'''
 In /themes/twentyfourteen/inc/template-tags.php, if you replace

 {{{
 previous_post_link( '%link', __( '<span class="meta-nav">Previous
 Post</span>%title', 'twentyfourteen' ) );
 next_post_link( '%link', __( '<span class="meta-nav">Next
 Post</span>%title', 'twentyfourteen' ) );
 }}}
 with

 {{{
 previous_post_link( '%link', __( '<span class="meta-nav">Previous
 Post</span>%title', 'twentyfourteen' ), true );
 next_post_link( '%link', __( '<span class="meta-nav">Next
 Post</span>%title', 'twentyfourteen' ), true );
 }}}
 , the previous/next links are not displayed while they worked correctly on
 WP 3.8.1.

 '''Case 2: previous_post_link/next_post_link returns nothing when
 "excluded_terms" parameter is specified'''
 In /themes/twentyfourteen/inc/template-tags.php, if you replace
 {{{
 previous_post_link( '%link', __( '<span class="meta-nav">Previous
 Post</span>%title', 'twentyfourteen' ) );
 next_post_link( '%link', __( '<span class="meta-nav">Next
 Post</span>%title', 'twentyfourteen' ) );
 }}}
 with

 {{{
 previous_post_link( '%link', __( '<span class="meta-nav">Previous
 Post</span>%title', 'twentyfourteen' ), false, '2' );
 next_post_link( '%link', __( '<span class="meta-nav">Next
 Post</span>%title', 'twentyfourteen' ), false, '2');
 }}}
 , again the previous/next links are not displayed while they worked
 correctly on WP 3.8.1.
