Unraid OS 6.10-rc4 Now Available

6 10rc4
As always before updating, please create a backup of your USB flash via "Main/Flash/"Flash Backup".

This is primarily a bug fix release. We are committed to producing releases as quickly as possible as soon as issues are fixed and small improvements are made. The main issues addressed with rc4 are nchan errors, DNS Rebinding Protection check, and an XFS formatting issue.

It would be extremely helpful to us to report issues and bugs by creating a separate Bug Report.
