NETGEAR announced the availability ReadyNAS firmware version 6.9.0 on Oct. 19th. Additionally, ReadyNAS devices will notify admins that their devices can be upgraded to this version when they sign in to the NETGEAR admin UI.
At this time, we strongly advise admins NOT to upgrade to firmware version 6.9.0 as it will break software compatibility with Egnyte Storage Sync. The Egnyte team is in the process of qualifying a Storage Sync release. Please check back here for the availability announcement of the compatible Storage Sync version.
