The release is imminent, but one of our requirements for a release is to deploy the latest version to discuss(.flarum.org). As we've moved discuss into a private git repository we need to slightly modify the deployment process as we're going to tackle continuous deployment from that repository to production in one go.
Our apologies for the delay. Please note that we're doing a lot of other things behind the scenes, including organisationally which will shape the future of Flarum. 2019 will be a great year, promised 😉
