Masterpress 1.3.6 is a compatibility release. It resolves an edge case with shared fieldsets not working for MySQL 8 when the fieldset is limited to more than 1 post type or taxonomy or excluding any post types or taxonomies.
WOOF_Inflector :: titleize( String $word, String $uppercase = "" )
Converts an underscored or CamelCase word into a English sentence, with each word having an uppercased first letter by default.
The titleize function converts text like “WelcomePage”, “welcome_page” or “welcome page” to this “Welcome Page”.
If second parameter is set to ‘first’ it will only capitalize the first character of the title.
