It looks like there is a second hotfix release for NetWorker 8.0 SP4, but there are no release notes or Hotfixes readme file showing what is fixed or what are the new features with this release (if there are any)!
It is release 18.104.22.168, Build 441.
So, I’m waiting for EMC to put readme file or release note. Please stay tuned…:-)
If you need a specific OS binary of this release, then make contact with EMC Technical support, and they will for sure give you the right thing you need.
These packages are also available at: ftp://ftp.legato.com/pub/NetWorker/Cumulative_Hotfixes/8.0/22.214.171.124/
After downloading the necessary binary, make sure it is the good build!
