# This script will get a list of currently supported versions from phpmyadmin.net.

# For each version, it pulls the Docker image for each flavor, including major and minor

# version shortcuts (5, 5.0, and 5.0.0). We check that the expected version is listed in ChangeLog.

#

# Future versions could use jq to parse package.json for the "version" field
