# New Features

27 Jan 2024: Introduced two new methods
1. Settings::section_exists(&self, section_name: &str) -> bool
As the name of the method itself says, it returns a boolean value that indicates whether the section exists or not
2. Settings::key_exists(&self, section_name: &str, key: &str) -> bool
As the name of the method itself says, it returns a boolean value that indicates whether the key exists or not
