disable lightbox on home page (and lists, tags etc…)

What “old plugin behaviour” do you refer to? There was never an option to exclude the plugin on the home page or archive pages.

If you need this, you can do this by adding a custom filter in your themes functions.php as described in the FAQ:

function my_lbwps_enabled($enabled, $id)
{
    // Disable the plugin for home page and archive pages
    if (is_front_page() || is_archive()) {
        return false;
    }

    return $enabled;
}

add_filter('lbwps_enabled', 'my_lbwps_enabled', 10, 2);

Edit:

Also note that for SEO it makes no difference, if the frontend script for the lightbox is loaded or not.

THIS!:
3.0
…New backend interface…
…added option to exclude…
==>> The lightbox will no longer be disabled on the home page, archive pages or search results if it is disabled in one or more pages/posts.

The old behaviour before 3.0 was to include the plugin also on the homepage and archive pages by default. It was only excluded of one of the pages or posts visible on the home page or on an archive page.
