 * As you’ve probably seen in the blog WordPress 3.1 Beta is out now.
 * Please be sure to reference this **known issue** if you attempt use of it.
 * >  I’ll start with a known issue that many of you are likely going to see:
   >  Fatal
   > error: Call to a member function is_page() on a non-object in /wp-includes/
   > query.php
   > is_page() may be any conditional tag from
   >  [http://codex.wordpress.org/Conditional_Tags](http://codex.wordpress.org/Conditional_Tags).
   > Here’s the issue: A theme or plugin is doing something wrong. Some code is 
   > checking the value of a conditional tag before we actually set up the Query,
   > which means they don’t work yet.
