 # Changes
 
 ### Version 2.3.0:
 
- * Fixed bug where if the user-agent passed to `isAllowed()` / `isDisallowed()` is called "constructor" it would throw an error.
- * Added support for relative URLs. This does not affect the default behavior so can safely be upgraded.
- 
-   Relative matching is only allowed if both the robots.txt URL and the URLs being checked are relative.
