Bug fixes

• Fixed issue, that the Local UI does not display progress information during volume export operations.
• Fixed issue, that the Workload Audit Logs are currently not stored on dedicated storage, which does not comply with the requirements outlined in IEC 62443-4-2.
• Fixed issue, when the Local Repository configuration is saved via the Local UI, the password is returned in plaintext in the response to a GET API request.
• Fixed issues, where in rare cases, an error window may appear in the Connection Manager. The functionality of the Connection Manager is not affected by this.

Known issues and limitations

• Changing an external interface in LocalUI (e.g. extern1) to unconfigured (from previously on DHCP) may yield in losing the network connection.
• DNA State is not updated, when updating a version of a Workload, on a device where the target DNA file did not included workload hashes.
• MFN 100, Siemens Simatic BX39 and Siemens Simatic IPC427 are not supported yet for Secure boot and Disk Encryption operation. Installation of Nerve 3.0 is potentially failing.
