-# PIL is affected by CVE-2023-4863
-#   https://nvd.nist.gov/vuln/detail/CVE-2023-4863
-# 
-# The vulnerability is patched in Pillow >= 10.0.1. This version does not support Python 3.7 due to this version being end-of-life.
-# Python 3.7.3 is the default Python version for Raspbian / Raspberry Pi OS, and upgrading Python versions is difficult for non-technical users.
-#
-# Therefore, addressing the CVE at this time would be a breaking change for most users without an easy upgrade path to Python 3.8+.
