## Change History
__2.2.0:__
* [`pyghidra.open_program()`](#pyghidraopen_program) and
[`pyghidra.run_script()`](#pyghidrarun_script) now accept a `nested_project_location` parameter
which can be set to `False` to open existing Ghidra projects that were created with the
Ghidra GUI.
__2.1.0:__
* [`pyghidra.open_program()`](#pyghidraopen_program) now accepts a `program_name` parameter, which
can be used to override the program name derived from the `binary_path` parameter.
