In templates comments.tpl and picture.tpl we have replaced:

{include file='comment_list.tpl' comment_derivative_params=$derivative_params}

by

{if isset($COMMENT_LIST)}
  {$COMMENT_LIST}
{else}
  {include file='comment_list.tpl' comment_derivative_params=$derivative_params}
{/if}

All themes with a custom comments.tpl or picture.tpl should apply the same change.

In index.tpl, in the H2 (breadcrumbs) the number of photos of the current section is no longer in the $TITLE template variable, but provided separately in $NB_ITEMS. You need to update your index.tpl (if not using the default theme one). Replace:

<h2>{$TITLE}</h2>

by

<h2>{$TITLE} {if $NB_ITEMS > 0}<span class="badge nb_items">{$NB_ITEMS}</span>{/if}</h2>

To replace the aspect of badges (actually between brackets), you can add in your theme.css:

.badge {
  background-color: #808080;
  color: black;
  padding: 1px 5px;
  border-radius: 10px;
  font-size: 10px;
}
 
.badge:before
{
   content : '';
}
 
.badge:after
{
  content : '';
}
 
dl#mbCategories li {
  margin-top: 3px ;
  margin-bottom: 3px;
}

trigger_notify("delete_tags", $tag_ids);
trigger_notify('delete_group', $groupids);

• pwg.users.favorites.remove
• pwg.users.favorites.getList

The single_insert function now can perform an INSERT IGNORE (just like mass_inserts) :

single_insert($table_name, $data, array('ignore' => true));
