Release Notes

rhysd/actionlint (actionlint)

v1.7.12

Compare Source

  on:
    schedule:
      # ERROR: The timezone is not a valid IANA timezone string
      - cron: '*/5 * * * *'
        timezone: 'Asia/Somewhere'

• Support the jobs.<job_name>.environment.deployment configuration. (#​639, thanks @​springmeyer)
