 ## [Unreleased]
 
+### Changed
+- Python 3.12 is the floor (`requires-python = ">=3.12"`): netOrk runs every driver
+  on 3.12, so 3.10 and 3.11 are no longer tested (NAPALM/driver-standard#6).
+- The floor on napalm is 5.1: older releases import `pkg_resources`, which a Python
+  3.12 venv no longer has.
+- The floor on urllib3 is 1.26.5: older releases bundle a `six` that Python 3.12
+  cannot import.
+
 ## [0.6.0] - 2026-10-23
 
 The first release on PyPI.
