Currently downloads for 1.8.8 are not showing because Maven uploads are failing. I've tried to reach out to several people about this to no avail. I'm leaving this here so people know that I am aware of this issue.

This has been addressed now and builds are appearing as normal, changelogs and all. This shouldn't be an issue for a while now, provided the Forge guys don't completely reconfigure everything on Jenkins and/or Forge Gradle.
