👋🏽 I maintain the cran checks badges. Please change to the new cran checks badge URL (e.g., https://badges.cranchecks.info/worst/rgbif.svg). Old badges at (e.g. https://cranchecks.info/badges/worst/rgbif) will be unavailable as of Jan 1st 2023.

• Blog post announcing the change: https://recology.info/2022/06/cran-checks-badges/
• New badges repo: https://github.com/r-hub/cchecksbadges
• Old badges repo: https://github.com/sckott/cchecksapi
