I received the following notice after publishing the air permit data just now:

The set-output command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

You can see it on the following run: https://github.com/NYCPlanning/ceqr-app-data/actions/runs/5509099768
