April 2025: Security-focused dependency update in monte-carlo-data/apollo-agent to mitigate a vulnerability by upgrading Jinja2 to 3.1.6. The patch touched multiple dependency files (requirements.in, requirements.txt, requirements-dev.txt) and was implemented via two commits: ca40926688bc342c184b936d2741efff5a490a05 (Bump jinja2 for VULN) and 1ac9ba45bcb84aaed10ffdd325591962a0255271 (Update requirements-dev.txt). Result: improved security posture, ensured compliance, and reduced exposure risk for downstream consumers.
