 - Install and log in to Codex CLI. The default `--ai-command` uses `codex exec`, so the installed Codex CLI must support `exec`, `--sandbox read-only`, `--ephemeral`, `--output-schema`, `--output-last-message`, and `-m <model>`. If you use `--ai-provider azure` instead, Codex CLI is not required; set `AZURE_OPENAI_KEY` and `AZURE_OPENAI_BASE_URL` (or `OPENAI_BASE_URL`) environment variables.

+Use Codex to generate release notes:

     --version 8.5.7 \
     --excel /path/to/release-note-excel.xlsx \

+export GITHUB_TOKEN=<your-token>
