Description of problem: Known Issues tracker bug for 3.1.2 release.
Removing 1230679 based on Federico's comment (https://bugzilla.redhat.com/show_bug.cgi?id=1230679#c53)
We are switching default tcmalloc threadcache from 32MB to 128MB. We need to document this change, explain the performance enhancement it brings, and provide an example of how to set it back to 32MB if so desired. Please include a link to the documentation on how to set the cache size.
Feature-wise, the headliners are 1. SELinux 2. Ubuntu Package cache (Apt-Cacher-NG) configuration for disconnected environments 3. Satellite 5 support
Tech Previews. We have a tech preview of Ceph as a Docker image; we are currently sorting out the logistics of refreshing it to 1.3.2 and adding it to the red hat registry so we can announce it at the same time as the release for better visibility. Jim Curtiss (added to the bug) will outline a paragraph or two for the release notes indicating how a user can test the image ("docker pull....") and pointers to any further documentation.
