Posts, Post Types: Deprecate `get_page_by_title()` in favour of `WP_Query`.
Formally deprecate `get_page_by_title()`. In its current form the function is unpredictable in that it may return a result that leads to a 404 error and will return different results depending on the database version/engine combination used.
It is recommended developers use `WP_Query` instead:
{{{
$query = new WP_Query(
array(
'post_type' => 'page',
'title' => 'Sample Page',
)
);
}}}
