WordPress 3.1 Beta

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
https://codex.www.ads-software.com/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.

Quoted from Nacin in the test list.
