 ## Unreleased
 
 ### Fixed
-- Fix Colab renderer detection to use `COLAB_NOTEBOOK_ID` env var instead of importing `google.colab`, so the `colab` renderer is only set for Colab web notebooks and not for other environments like the Colab VS Code extension [[#5473](https://github.com/plotly/plotly.py/pull/5473)]
+- Use presence of `COLAB_NOTEBOOK_ID` env var to enable Colab renderer instead of testing import of `google.colab` [[#5473](https://github.com/plotly/plotly.py/pull/5473)], with thanks to @kevineger for the contribution!
 - Fix issue where user-specified `color_continuous_scale` was ignored when template had `autocolorscale=True` [[#5439](https://github.com/plotly/plotly.py/pull/5439)], with thanks to @antonymilne for the contribution!
 - Update tests to be compatible with numpy 2.4 [[#5522](https://github.com/plotly/plotly.py/pull/5522)], with thanks to @thunze for the contribution!
