Are there plans to update to 4.2? I recently moved from a windows server that I had backed up with CrashPlan 4.2 to unRAID and now I can't restore any of those backups due to the version difference. I just see the error "Unable to restore due to a backup archive cryptography key error." which the problem/solution seems to be directly related to the version. I know I can restore to another machine and copy the files over - but that's a bit painful.
