Changeset 30074 for trunk/src/wp-includes/theme.php

Timestamp:

Message:

Introduce a new means of outputting a <title> tag in the theme head. Requires a theme to add support by calling add_theme_support( 'title-tag' ). This is the first step in adding a more robust means of generating and outputting the title tag.

See #18548.
