Nessus Pro 8.1 is now available.

https://docs.tenable.com/releasenotes/nessus/nessus810.htm

The following are the new features included in the Nessus Pro 8.1.0 Release:

• Dynamic Scan Policies – Often you may need to scan your client's environment for vulnerabilities with a specific type of behavior, for example, all vulnerabilities with a known exploit. In the past, with each plugin release, users would have to add each of these plugins to their policy manually. Now, using Dynamic Scan Policies, users can build a scan by creating a specific filter, e.g., all exploitable, and incorporating the filter into the scan policy. By using these filters with your scan policies, new plugins that match the filter are automatically added to the policy.
• Revamped Advanced Settings Page - Improved the Advanced Settings UI in Nessus Pro to allow for a more straightforward view of these advanced controls. 
• Remote Log Extraction - Troubleshooting scans and agents can be a significant challenge. With the release of 8.0, we simplified this by allowing users to collect local logs directly from the UI. With this release, we are laying the foundation to also be able to request remote logs from managed scanners and agents. NOTE: scanners will need to be running 8.1 above and agents will need to be running 7.2 which is planned to be released in the coming weeks.
• Internationalized Dates -  Update the Nessus UI to use the international standard date notation, YYYY-MM-DD, where dates are shown.
• Update to SSL Ciphers - Use strong ciphers by default when negotiating SSL connections.
• Non-credentialed scan optimization - To decrease the time it takes to run scans, we have updated the logic for non-credentialed scans launched from Nessus to avoid running specific plugins that require credentials to work. Additionally, this significantly improves scan times for Host Discovery scans.
