Thanks @merefield - the version check server needed some tweaks to understand the new -dev
suffix on tests-passed version numbers. Should be working now:
[7] pry(main)> Discourse::VERSION::STRING
=> "3.2.0.beta1-dev"
[8] pry(main)> DiscourseHub.discourse_version_check
=> {"success"=>"OK", "latestVersion"=>"3.1.0.beta7", "criticalUpdates"=>false, "missingVersionsCount"=>0}
