BigBox 2.x brings the first breaking changes to the theme’s development. While the changes are minor, they are not backwards compatible.

Breaking Changes

Previously:

add_action( 'wp_enqueue_scripts', 'bigbox_enqueue_styles', 10 );

Now:

add_action( 'wp_enqueue_scripts', 'bigbox_enqueue_styles', 20 );

Reason:

This allows for integrations, child themes, plugins, etc to filter the inline CSS on the default priority before the parent theme outputs it.

Previously

The parent theme’s uncompiled stylesheet was named style.scss

Now:

The parent theme’s uncompiled stylesheet is named app.scss

Reason:

Naming consistency.
