Comment 9 Adam Williamson 2017-05-26 21:12:01 UTC
Discussed at 2017-05-25 Fedora 26 Beta Go/No-Go meeting, acting as a freeze exception review meeting: https://meetbot-raw.fedoraproject.org/fedora-meeting-2/2017-05-25/f26-beta-go-no-go-meeting.2017-05-25-17.00.html . Accepted as a freeze exception issue, as we definitely want to avoid shipping Beta with widely-publicized, significant security vulns.
