Upgrade Notes

  • You can upgrade to the latest version of Nessus from any previously supported version.
  • If your upgrade path skips versions of Nessus, Tenable recommends reviewing the release notes for all skipped versions to learn about new features and bug fixes.
  • If you upgrade to this version of Nessus and downgrade later on, run the following command to ensure support for Internet Explorer: nessuscli fix --set ssl_cipher_list=compatible.
  • If you want your scanners to update to the newest version before the GA date automatically, set your Nessus Update Plan to Opt in to Early Access releases.
  • If you want to update your scanners to the latest version before the GA date manually, disable automatic updates so the scanner does not automatically downgrade to the previous version.
  • For Nessus 8.8.0 and later running on Windows, you must install Visual C++ Redistributable for Visual Studio 2015 on the host operating system. The following Windows versions require a minimum Service Pack to be installed:

    • Windows 7 SP1
    • Windows Server 2008 SP2
    • Windows Server 2008 R2 SP1
