This project doesn't really do anything that could be a security issue. It is simply a library. Using it is left to the user.
The development of fluids is linear at this time; upgrade fluids to the latest version to obtain any security fixes, in the event that there ever are any.
This project has the following automated security scanning tools setup via GitHub Actions:
- pip-audit: Scans dependencies for known security vulnerabilities
 - bandit: Performs static analysis to identify common security issues in Python code
 
It is not expected any vulnerabilities would be found on a library used for calculations. The inclusion of scanners is a general best practice, not an indication of concern.
