A security concern was identified and action was taken to resolve it by removing the deprecated Ubuntu 14.04 and 16.04 Probo images that were planned for removal in our September Probo release effective immediately. The Probo Container Manager service was restarted to load the updated approved images list.
Probo users that have defined an Ubuntu 16.04 or Ubuntu 14.04 image in their .probo.yaml configuration file will need to update their image to the respective 18.04 image that we have available for their version of PHP to submit new Probo builds. Probo users that did not define an image in their .probo.yaml may need to add an image specific to their version of PHP used in Production, as the new default image is now proboci/ubuntu:18.04-php7.3 for all new Probo builds without an image defined. The old default Probo image was running PHP 5.6, which we also planned to update to PHP 7.3 as the default version in the September release.
