Will the new heading changes in 4.3 affect APF?

Hi,

It should be fine.

Just tried WordPress 4.3beta4 and although APF still uses h2 for the screen title element, I could not find any noticeable difference from using h1.

If you need to change the heading title element tag, you can do something like this in the setUp() method.

$this->setPageHeadingTabTag( 'h1' );

However, you want to keep in mind that APF automatically creates a navigation bar for added pages and each tabbed page title uses the set tag, h2 by default. Only one h1 tag element is supposed to exist in a page. So when you set h1, you want to make sure that no navigation bar is created.

For in-page tabs, you can use the setInPageTabTag() method.

$this->setInPageTabTag( 'h1' );
