18-October-2016 This is critical update release to fix a really terrible bug in an otherwise invisible system function. There is a “cleaner” that runs on Feed folders to remove documents older than 30 days. This is in place to keep Feed folders from growing out of control. Modifications to this cleaner (for use in other areas of the system) resulted in workflow rules being deleted from all Feed folders. Action is required to recover from this error. See your email and the Insiders Slack channel for instructions.
