New Probo docker images are now available for PHP 7.3 and PHP 7.4 for public testing. These images should be considered "beta" until we have added them to our official Probo Docker Images page, https://docs.probo.ci/build/images/. Please report any issues using these new images through our Slack support chat or Zendesk.
Add one of the following lines to your .probo.yaml file to enable PHP 7.3 or PHP 7.4 respectively, or update your existing image setting to one of the new image names.
