Requirements

Python	3.10 or higher
Git	2.22 or higher

Git also needs to be added to the system PATH.

Limitations

At its core, diffhouse is a data extraction tool and therefore does not calculate software metrics like code churn or cyclomatic complexity; if this is needed, take a look at PyDriller instead.
