 Bugs Fixed
 **********
 
+- **CLIRequest:** Fixed a bug where ``parseCommand()`` could throw a TypeError when ``argv`` is missing.
 - **Content Security Policy:** Fixed a bug where empty ``Content-Security-Policy``, ``Content-Security-Policy-Report-Only``, and ``Reporting-Endpoints`` response headers were generated when no corresponding values existed.
 - **Logger:** Fixed a bug where interpolating a log message with array or non-stringable context values could raise PHP warnings or errors.
